Abstract
BACKGROUND Fracture of the distal radius is a common clinical problem. A key method of surgical fixation is percutaneous pinning, involving the insertion of wires through the skin to stabilise the fracture. This is an update of a Cochrane Review published in 2007. OBJECTIVES To assess the effects (benefits and harms) of percutaneous pinning versus cast immobilisation alone and of different methods and techniques of percutaneous pinning, modalities or duration of immobilisation after pinning, and methods or timing of pin or wire removal for treating fractures of the distal radius in adults. Our primary focus was on dorsally displaced fractures. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, trial registers, conference proceedings and reference lists of articles up to June 2019. SELECTION CRITERIA Randomised or quasi-randomised controlled clinical trials involving adults with a fracture of the distal radius, which compared percutaneous pinning with non-surgical treatment or different aspects of percutaneous pinning. Our main outcomes were patient-reported function at the short term (up to three months), medium term (three up to 12 months) and long term (greater than 12 months); overall numbers of participants with complications requiring secondary treatment and any complication; grip strength and health-related quality of life at 12 months. DATA COLLECTION AND ANALYSIS At least two review authors independently performed study screening and selection, 'Risk of bias' assessment and data extraction. We pooled data where appropriate and used GRADE for assessing the quality of evidence for each outcome. MAIN RESULTS We included 21 randomised controlled trials (RCTs) and five quasi-RCTs, involving 1946 generally older and female adults with dorsally displaced and potentially or evidently unstable distal radial fractures. Trial populations varied but the majority of studies reported mean ages in the sixth decade or older. All trials were at high risk of bias, invariably performance bias - which for most trials reflected the impracticality of blinding care providers or participants to treatment allocation - and often detection bias and selective reporting bias. Allocation concealment was secure in one trial only. All trials reported outcomes incompletely. The studies tested one of 10 comparisons. In the following, we report on those of the main outcomes for which evidence was available. No subgroup analysis, such as by pinning methods, was viable. Eleven heterogeneous trials involving 917 participants compared percutaneous pinning with plaster cast immobilisation after closed reduction of the fracture. The quality of the evidence was very low for all reported outcomes. Thus, we are uncertain if percutaneous pinning compared with plaster cast alone makes any difference to patient-reported function, measured using the DASH questionnaire, at six weeks or six months (incomplete data from one trial). Overall numbers of participants with complications were not reported. Redisplacement resulting in secondary treatment occurred on average in 12% (range 3.3% to 75%) of participants treated by cast alone (six trials) whereas pin tract infection requiring antibiotics and, often, early wire removal, occurred on average in 7.7% (range 0% to 15%) of pinning group participants (seven trials). We are uncertain whether pinning makes a difference to the incidence of complex regional pain syndrome, reported in four studies. Although two studies found finger stiffness after cast removal was less common after pinning (20% versus 36%), the treatment implications were not reported. Other reported complications were mainly surgery-related. Based on incomplete data or qualitative statements from only four studies, we are uncertain of the effects of pinning on grip strength at 12 months. We are uncertain if percutaneous pinning compared with plaster cast alone makes any difference to patient-reported quality of life at four months (one study). Five comparisons of different pinning methods were made by six trials in all. One of these trials, which reported results for 96 participants, compared Kapandji intrafocal pinning (2 or 3 wires) with early mobilisation versus trans-styloid fixation (2 wires) with six weeks cast immobilisation. We are uncertain whether Kapandji pinning slightly increases the risk of superficial radial nerve symptoms or complex regional pain syndrome, or whether it makes a difference in grip strength at 12 months (very low-quality evidence). Two small trials using two distinct pinning techniques compared biodegradable pins versus metal pins in 70 participants. Although very low-quality evidence, the extra demands at surgery of insertion of biodegradable pins and excess of serious complications (e.g. severe osteolytic reactions) associated with biodegradable material are important findings. Three poorly-reported trials involving 168 participants compared burying of wire ends versus leaving them exposed. We are uncertain whether burying of wires reduces the incidence of superficial infection (very low-quality evidence). There is low-quality evidence that burying of wires may be associated with a higher risk of requiring more invasive treatment for wire removal. Four small trials compared different types or duration of postoperative immobilisation. Very low-quality evidence of small between-group differences in individual complications and grip strength at 17 weeks, means we are uncertain of the effects of positioning the wrist in dorsiflexion versus palmar flexion during cast immobilisation following pinning of redisplaced fractures (one trial; 60 participants). Three small heterogeneous trials compared cast immobilisation for one week (early mobilisation) versus four or six weeks after percutaneous pinning in 170 people. Although we note one trial using Kapandji pinning reported more complications in the early group, the very low-quality evidence means there is uncertainty of the effects of early mobilisation on overall and individual complications, or grip strength at 12 months. No trials tested different methods for, or timing of, pin/wire removal. AUTHORS' CONCLUSIONS Overall, there is insufficient RCT evidence to inform on the role of percutaneous pinning versus cast immobilisation alone or associated treatment decisions such as method of pinning, burying or not of wire ends, wrist position and duration of immobilisation after pinning. Although very low-quality evidence, the serious complications associated with biodegradable materials is noteworthy. We advise waiting on the results of a large ongoing study comparing pinning with plaster cast treatment as these could help inform future research.

Abstract
BACKGROUND Dislocation of the acromioclavicular joint is one of the most common shoulder injuries in a sport-active population. The question of whether surgery should be used remains controversial. This is an update of a Cochrane Review first published in 2010. OBJECTIVES To assess the effects (benefits and harms) of surgical versus conservative (non-surgical) interventions for treating acromioclavicular dislocations in adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (to June 2019), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2019, Issue 6), MEDLINE (1946 to June 2019), Embase (1980 to June 2019), and LILACS (1982 to June 2019), trial registries, and reference lists of articles. There were no restrictions based on language or publication status. SELECTION CRITERIA We included all randomised and quasi-randomised trials that compared surgical with conservative treatment of acromioclavicular dislocation in adults. DATA COLLECTION AND ANALYSIS At least two review authors independently performed study screening and selection, 'Risk of bias' assessment, and data extraction. We pooled data where appropriate and used GRADE to assess the quality of evidence for each outcome. MAIN RESULTS We included five randomised trials and one quasi-randomised trial. The included trials involved 357 mainly young adults, the majority of whom were male, with acute acromioclavicular dislocation. The strength of the findings in all studies was limited due to design features, invariably lack of blinding, that carry a high risk of bias. Fixation of the acromioclavicular joint using hook plates, tunnelled suspension devices, coracoclavicular screws, acromioclavicular pins, or (usually threaded) wires was compared with supporting the arm in a sling or similar device. After surgery, the arm was also supported in a sling or similar device in all trials. Where described in the trials, both groups had exercise-based rehabilitation. We downgraded the evidence for all outcomes at least two levels, invariably for serious risk of bias and serious imprecision.Low-quality evidence from two studies showed no evidence of a difference between groups in shoulder function at one year, assessed using the Disability of the Arm, Shoulder, and Hand questionnaire (DASH) (0 (best function) to 100 (worst function)): mean difference (MD) 0.73 points, 95% confidence interval (CI) -2.70 to 4.16; 112 participants. These results were consistent with other measures of function at one-year or longer follow-up, including non-validated outcome scores reported by three studies. There is low-quality evidence that function at six weeks may be better after conservative treatment, indicating an earlier recovery. Very low-quality evidence from one trial found no difference between groups in participants reporting pain at one year: risk ratio (RR) 1.32, 95% CI 0.54 to 3.19; 79 participants. There is very low-quality evidence that surgery may not reduce the risk of treatment failure, usually resulting in non-routine secondary surgery: 14/168 versus 15/174; RR 0.99, 95% CI 0.51 to 1.94; 342 participants, 6 studies. The main source of treatment failure was complications related to surgical implants in the surgery group and persistent symptoms, mainly discomfort, due to the acromioclavicular dislocation in the conservatively treated group.There is low-quality evidence from two studies that there may be little or no difference between groups in the return to former activities (sports or work) at one year: 57/67 versus 62/70; RR 0.96, 95% CI 0.85 to 1.10; 137 participants, 2 studies. Low-quality but consistent evidence from four studies indicated an earlier recovery in conservatively treated participants compared with those treated with surgery. There is low-quality evidence of no clinically important difference between groups at one year in quality of life scores, measured using the 36-item or 12-item Short Form Health Survey (SF-36 or SF-12) (0-to-100 scale, where 100 is best score), in either the physical component (MD -0.63, 95% CI -2.63 to 1.37; 122 participants, 2 studies) or mental component (MD 0.47 points, 95% CI -1.51 to 2.44; 122 participants). There is very low-quality and clinically heterogenous evidence of a greater risk of an adverse event after surgery: 45/168 versus 16/174; RR 2.82, 95% CI 1.65 to 4.82; 342 participants, 6 studies; I2 = 48%. Common adverse outcomes were hardware complications or discomfort (18.5%) and infection (8.7%) in the surgery group and persistent symptoms (7.1%), mainly discomfort, in the conservatively treated group. The majority of surgical complications occurred in older studies testing now-outdated devices known for their high risk of complications. The very low-quality evidence from one study (70 participants) means that we are uncertain whether there is a between-group difference in patient dissatisfaction with cosmetic results.It is notable that the evidence for function, return to former activities, and quality of life came from the two most recently conducted studies, which tested currently used devices and interventions in clearly defined participant populations that represented the commonly perceived population for which there is uncertainty over the use of surgery. There were insufficient data to conduct subgroup analysis relating to type of injury and whether surgery involved ligament reconstruction or not. AUTHORS' CONCLUSIONS There is low-quality evidence that surgical treatment has no additional benefits in terms of function, return to former activities, and quality of life at one year compared with conservative treatment. There is, however, low-quality evidence that people treated conservatively had improved function at six weeks compared with surgical management. There is very low-quality evidence of little difference between the two treatments in pain at one year, treatment failure usually resulting in secondary surgery, or patient satisfaction with cosmetic result. Although surgery may result in more people sustaining adverse events, this varied between the trials, being more common in techniques such as K-wire fixation that are rarely used today. There remains a need to consider the balance of risks between the individual outcomes: for example, surgical adverse events, including wound infection or dehiscence and hardware complication, against risk of adverse events that may be more commonly associated with conservative treatment such as persistent symptoms or discomfort, or both.There is a need for sufficiently powered, good-quality, well-reported randomised trials of currently used surgical interventions versus conservative treatment for well-defined injuries.

Abstract
BACKGROUND Acute anterior shoulder dislocation, which is the most common type of dislocation, usually results from an injury. Subsequently, the shoulder is less stable and is more susceptible to re-dislocation or recurrent instability (e.g. subluxation), especially in active young adults. After closed reduction, most of these injuries are treated with immobilisation of the injured arm in a sling or brace for a few weeks, followed by exercises. This is an update of a Cochrane Review first published in 2006 and last updated in 2014. OBJECTIVES To assess the effects (benefits and harms) of conservative interventions after closed reduction of traumatic anterior dislocation of the shoulder. These might include immobilisation, rehabilitative interventions or both. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, CINAHL, PEDro and trial registries. We also searched conference proceedings and reference lists of included studies. Date of last search: May 2018. SELECTION CRITERIA We included randomised or quasi-randomised controlled trials comparing conservative interventions with no treatment, a different intervention or a variant of the intervention (e.g. a different duration) for treating people after closed reduction of a primary traumatic anterior shoulder dislocation. Inclusion was regardless of age, sex or mechanism of injury. Primary outcomes were re-dislocation, patient-reported shoulder instability measures and return to pre-injury activities. Secondary outcomes included participant satisfaction, health-related quality of life, any instability and adverse events. DATA COLLECTION AND ANALYSIS Both review authors independently selected studies, assessed risk of bias and extracted data. We contacted study authors for additional information. We pooled results of comparable groups of studies. We assessed risk of bias with the Cochrane 'Risk of bias' tool and the quality of the evidence with the GRADE approach. MAIN RESULTS We included seven trials (six randomised controlled trials and one quasi-randomised controlled trial) with 704 participants; three of these trials (234 participants) are new to this update. The mean age across the trials was 29 years (range 12 to 90 years), and 82% of the participants were male. All trials compared immobilisation in external rotation (with or without an additional abduction component) versus internal rotation (the traditional method) following closed reduction. No trial evaluated any other interventions or comparisons, such as rehabilitation. All trials provided data for a follow-up of one year or longer; the commonest length was two years or longer.All trials were at some risk of bias, commonly performance and detection biases given the lack of blinding. Two trials were at high risk of selection bias and some trials were affected by attrition bias for some outcomes. We rated the certainty of the evidence as very low for all outcomes.We are uncertain whether immobilisation in external rotation makes a difference to the risk of re-dislocation after 12 months' or longer follow-up compared with immobilisation in internal rotation (55/245 versus 73/243; risk ratio (RR) 0.67, 95% confidence interval (CI) 0.38 to 1.19; 488 participants; 6 studies; I² = 61%; very low certainty evidence). In a moderate-risk population with an illustrative risk of 312 per 1000 people experiencing a dislocation in the internal rotation group, this equates to 103 fewer (95% CI 194 fewer to 60 more) re-dislocations after immobilisation in external rotation. Thus this result covers the possibility of a benefit for each intervention.Individually, the four studies (380 participants) reporting on validated patient-reported outcome measures for shoulder instability at a minimum of 12 months' follow-up found no evidence of a clinically important difference between the two interventions.We are uncertain of the relative effects of the two methods of immobilisation on resumption of pre-injury activities or sports. One study (169 participants) found no evidence of a difference between interventions in the return to pre-injury activity of the affected arm. Two studies (135 participants) found greater return to sports in the external rotation group in a subgroup of participants who had sustained their injury during sports activities.None of the trials reported on participant satisfaction or health-related quality of life.We are uncertain whether there is a difference between the two interventions in the number of participants experiencing instability, defined as either re-dislocation or subluxation (RR 0.84, 95% CI 0.62 to 1.14; 395 participants, 3 studies; very low certainty evidence).Data on adverse events were collected only in an ad hoc way in the seven studies. Reported "transient and resolved adverse events" were nine cases of shoulder stiffness or rigidity in the external rotation group and two cases of axillary rash in the internal rotation group. There were three "important" adverse events: hyperaesthesia and moderate hand pain; eighth cervical dermatome paraesthesia; and major movement restriction between 6 and 12 months. It was unclear to what extent these three events could be attributed to the treatment. AUTHORS' CONCLUSIONS The available evidence from randomised trials is limited to that comparing immobilisation in external versus internal rotation. Overall, the evidence is insufficient to draw firm conclusions about whether immobilisation in external rotation confers any benefit over immobilisation in internal rotation.Considering that there are several unpublished and ongoing trials evaluating immobilisation in external versus internal rotation, the main priority for research on this question consists of the publication of completed trials and the completion and publication of ongoing trials. Meanwhile, evaluation of other interventions, including rehabilitation, is warranted. There is a need for sufficiently large, good-quality, well-reported randomised controlled trials with long-term follow-up. Future research should aim to determine the optimal immobilisation duration, precise indications for immobilisation, optimal rehabilitation interventions, and the acceptability of these different interventions.

Abstract
BACKGROUND At least one-third of community-dwelling people over 65 years of age fall each year. Exercises that target balance, gait and muscle strength have been found to prevent falls in these people. An up-to-date synthesis of the evidence is important given the major long-term consequences associated with falls and fall-related injuries OBJECTIVES: To assess the effects (benefits and harms) of exercise interventions for preventing falls in older people living in the community. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, three other databases and two trial registers up to 2 May 2018, together with reference checking and contact with study authors to identify additional studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) evaluating the effects of any form of exercise as a single intervention on falls in people aged 60+ years living in the community. We excluded trials focused on particular conditions, such as stroke. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Our primary outcome was rate of falls. MAIN RESULTS We included 108 RCTs with 23,407 participants living in the community in 25 countries. There were nine cluster-RCTs. On average, participants were 76 years old and 77% were women. Most trials had unclear or high risk of bias for one or more items. Results from four trials focusing on people who had been recently discharged from hospital and from comparisons of different exercises are not described here.Exercise (all types) versus control Eighty-one trials (19,684 participants) compared exercise (all types) with control intervention (one not thought to reduce falls). Exercise reduces the rate of falls by 23% (rate ratio (RaR) 0.77, 95% confidence interval (CI) 0.71 to 0.83; 12,981 participants, 59 studies; high-certainty evidence). Based on an illustrative risk of 850 falls in 1000 people followed over one year (data based on control group risk data from the 59 studies), this equates to 195 (95% CI 144 to 246) fewer falls in the exercise group. Exercise also reduces the number of people experiencing one or more falls by 15% (risk ratio (RR) 0.85, 95% CI 0.81 to 0.89; 13,518 participants, 63 studies; high-certainty evidence). Based on an illustrative risk of 480 fallers in 1000 people followed over one year (data based on control group risk data from the 63 studies), this equates to 72 (95% CI 52 to 91) fewer fallers in the exercise group. Subgroup analyses showed no evidence of a difference in effect on both falls outcomes according to whether trials selected participants at increased risk of falling or not.The findings for other outcomes are less certain, reflecting in part the relatively low number of studies and participants. Exercise may reduce the number of people experiencing one or more fall-related fractures (RR 0.73, 95% CI 0.56 to 0.95; 4047 participants, 10 studies; low-certainty evidence) and the number of people experiencing one or more falls requiring medical attention (RR 0.61, 95% CI 0.47 to 0.79; 1019 participants, 5 studies; low-certainty evidence). The effect of exercise on the number of people who experience one or more falls requiring hospital admission is unclear (RR 0.78, 95% CI 0.51 to 1.18; 1705 participants, 2 studies, very low-certainty evidence). Exercise may make little important difference to health-related quality of life: conversion of the pooled result (standardised mean difference (SMD) -0.03, 95% CI -0.10 to 0.04; 3172 participants, 15 studies; low-certainty evidence) to the EQ-5D and SF-36 scores showed the respective 95% CIs were much smaller than minimally important differences for both scales.Adverse events were reported to some degree in 27 trials (6019 participants) but were monitored closely in both exercise and control groups in only one trial. Fourteen trials reported no adverse events. Aside from two serious adverse events (one pelvic stress fracture and one inguinal hernia surgery) reported in one trial, the remainder were non-serious adverse events, primarily of a musculoskeletal nature. There was a median of three events (range 1 to 26) in the exercise groups.Different exercise types versus controlDifferent forms of exercise had different impacts on falls (test for subgroup differences, rate of falls: P = 0.004, I² = 71%). Compared with control, balance and functional exercises reduce the rate of falls by 24% (RaR 0.76, 95% CI 0.70 to 0.81; 7920 participants, 39 studies; high-certainty evidence) and the number of people experiencing one or more falls by 13% (RR 0.87, 95% CI 0.82 to 0.91; 8288 participants, 37 studies; high-certainty evidence). Multiple types of exercise (most commonly balance and functional exercises plus resistance exercises) probably reduce the rate of falls by 34% (RaR 0.66, 95% CI 0.50 to 0.88; 1374 participants, 11 studies; moderate-certainty evidence) and the number of people experiencing one or more falls by 22% (RR 0.78, 95% CI 0.64 to 0.96; 1623 participants, 17 studies; moderate-certainty evidence). Tai Chi may reduce the rate of falls by 19% (RaR 0.81, 95% CI 0.67 to 0.99; 2655 participants, 7 studies; low-certainty evidence) as well as reducing the number of people who experience falls by 20% (RR 0.80, 95% CI 0.70 to 0.91; 2677 participants, 8 studies; high-certainty evidence). We are uncertain of the effects of programmes that are primarily resistance training, or dance or walking programmes on the rate of falls and the number of people who experience falls. No trials compared flexibility or endurance exercise versus control. AUTHORS' CONCLUSIONS Exercise programmes reduce the rate of falls and the number of people experiencing falls in older people living in the community (high-certainty evidence). The effects of such exercise programmes are uncertain for other non-falls outcomes. Where reported, adverse events were predominantly non-serious.Exercise programmes that reduce falls primarily involve balance and functional exercises, while programmes that probably reduce falls include multiple exercise categories (typically balance and functional exercises plus resistance exercises). Tai Chi may also prevent falls but we are uncertain of the effect of resistance exercise (without balance and functional exercises), dance, or walking on the rate of falls.

Abstract
BACKGROUND Clavicle fractures are common, accounting for 2.6% to 4% of all fractures. Eighty per cent of clavicle fractures are located in the middle third of the clavicle. Although treatment of these fractures is usually non-surgical, displaced clavicle fractures may be considered for surgical treatment because of their greater risk of non-union. This is an update of a Cochrane Review first published in 2013. OBJECTIVES To assess the effects (benefits and harms) of surgical versus conservative interventions for treating middle third clavicle fractures. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Specialised Register, CENTRAL, MEDLINE, Embase, LILACS, trials registries and reference lists updated to December 2017. We did not apply any language or publication restrictions. SELECTION CRITERIA We considered randomised and quasi-randomised controlled trials evaluating surgical versus conservative interventions for treating fractures in the middle third of the clavicle. The primary outcomes were shoulder function or disability, pain and treatment failure, defined as the number of participants who had been given a non-routine secondary surgical intervention (excluding hardware removal), for symptomatic non-union, malunion or other complications. DATA COLLECTION AND ANALYSIS At least two review authors selected eligible studies, independently assessed risk of bias and cross-checked data. Where appropriate, we pooled results of comparable studies. MAIN RESULTS We included 14 studies involving 1469 participants with acute middle third clavicle fractures. All studies included adults, with the overall range from 17 to 70 years. Of the studies that reported gender, men were over-represented. Ten studies compared plate fixation with sling or figure-of-eight bandage, or both, and four studies compared intramedullary fixation with wearing either a sling or a figure-of-eight bandage. Almost all studies had design features that carry a high risk of bias, thus limiting the strength of their findings.Low-quality evidence from 10 studies (838 participants), showed that, compared with conservative treatment, surgical treatment of acute middle third clavicle fractures may not improve upper arm function at follow-up of one year or longer: standardised mean difference (SMD) 0.33, 95% confidence interval (CI) -0.02 to 0.67. We downgraded the quality of the evidence because of risk of bias and high statistical heterogeneity (I2 = 83%). This corresponds to a mean improvement of 2.3 points in favour of surgery (0.14 points worse to 4.69 points better), on the 100-point Constant score; this does not represent a clinically important difference. There may be no difference in pain measured using a visual analogue scale (0 to 100 mm; higher scores mean worse pain) between treatments (mean difference (MD) -0.60 mm, 95% CI -3.51 to 2.31; 277 participants, 3 studies; low-quality evidence reflecting risk of bias and imprecision). Surgery may reduce the risk of treatment failure, that is, number of participants who had non-routine secondary surgical intervention (excluding hardware removal), for symptomatic non-union, malunion or other complication (risk ratio (RR) 0.32, 95% CI 0.20 to 0.50; 1197 participants, 12 studies; low-quality evidence, downgraded for risk of bias and imprecision). The main source of treatment failure was mechanical failure (3.4%) in the surgery group and symptomatic non-union (11.6%) in the conservative-treatment group.We are uncertain whether surgery results in fewer people having one or more cosmetic problems, such as deformities, which were more common after conservative treatment, or hardware prominence or scarring, which only occurred in the surgery group (RR 0.55, 95% CI 0.31 to 0.98; 1130 participants, 11 studies; I2 = 63%; very low-quality evidence downgraded for risk of bias, imprecision and inconsistency). We are uncertain whether there is any difference between surgery and conservative treatment in the risk of incurring an adverse outcome that includes local infection, dehiscence, symptomatic malunion, discomfort leading to implant removal, skin and nerve problems: RR 1.34, 95% CI 0.68 to 2.64; 1317 participants, 14 studies; I2 = 72%; very low-quality evidence, downgraded for risk of bias, imprecision and inconsistency). Hardware removal for discomfort was a common adverse outcome in the surgery group (10.2%) while symptomatic malunion was more common in the conservative-treatment group (11.3% versus 1.2% in the surgery group). Infection occurred only in the surgery group (3.2%). There may be no between-group difference in quality of life at one year (SF-12 or SF-36 physical component scores: 0 to 100 scale, where 100 is the best score): MD 0.30 (95% CI -1.95 to 2.56, 321 participants, 2 studies; low-quality evidence downgraded for risk of bias and imprecision). AUTHORS' CONCLUSIONS There is low-quality evidence that surgical treatment has no additional benefits in terms of function, pain and quality of life compared with conservative treatment, but may result in fewer treatment failures overall. Very low-quality evidence means that we are very uncertain of the findings of a slightly better cosmetic result after surgery and of no difference between surgical and conservative treatment in the risk of adverse events. For both composite outcomes, there is a need to consider the balance of risks between the individual outcomes; for example, surgical adverse events, including wound infection or dehiscence and hardware irritation, against risk of adverse events that may be more commonly associated with conservative treatment such as symptomatic malunion and shoulder stiffness.Treatment options must be chosen on an individual patient basis, after careful consideration of the relative benefits and harms of each intervention and of patient preferences.

Abstract
BACKGROUND Wrist fractures, involving the distal radius, are the most common fractures in children. Most are buckle fractures, which are stable fractures, unlike greenstick and other usually displaced fractures. There is considerable variation in practice, such as the extent of immobilisation for buckle fractures and use of surgery for seriously displaced fractures. OBJECTIVES To assess the effects (benefits and harms) of interventions for common distal radius fractures in children, including skeletally immature adolescents. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group's Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, trial registries and reference lists to May 2018. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs comparing interventions for treating distal radius fractures in children. We sought data on physical function, treatment failure, adverse events, time to return to normal activities (recovery time), wrist pain, and child (and parent) satisfaction. DATA COLLECTION AND ANALYSIS At least two review authors independently performed study screening and selection, 'Risk of bias' assessment and data extraction. We pooled data where appropriate and used GRADE for assessing the quality of evidence for each outcome. MAIN RESULTS Of the 30 included studies, 21 were RCTs, seven were quasi-RCTs and two did not describe their randomisation method. Overall, 2930 children were recruited. Typically, trials included more male children and reported mean ages between 8 and 10 years. Eight studies recruited buckle fractures, five recruited buckle and other stable fractures, three recruited minimally displaced fractures and 14 recruited displaced fractures, typically requiring closed reduction, typically requiring closed reduction. All studies were at high risk of bias, mainly reflecting lack of blinding. The studies made 14 comparisons. Below we consider five prespecified comparisons:Removable splint versus below-elbow cast for predominantly buckle fractures (6 studies, 695 children)One study (66 children) reported similar Modified Activities Scale for Kids - Performance scores (0 to 100; no disability) at four weeks (median scores: splint 99.04; cast 99.11); low-quality evidence. Thirteen children needed a change or reapplication of device (splint 5/225; cast 8/219; 4 studies); very low-quality evidence. One study (87 children) reported no refractures at six months. One study (50 children) found no between-group difference in pain during treatment; very low-quality evidence. Evidence was absent (recovery time), insufficient (children with minor complications) or contradictory (child or parent satisfaction). Two studies estimated lower healthcare costs for removable splints.Soft or elasticated bandage versus below-elbow cast for buckle or similar fractures (4 studies, 273 children)One study (53 children) reported more children had no or only limited disability at four weeks in the bandage group; very low-quality evidence. Eight children changed device or extended immobilisation for delayed union (bandage 5/90; cast 3/91; 3 studies); very low-quality evidence. Two studies (139 children) reported no serious adverse events at four weeks. Evidence was absent, insufficient or contradictory for recovery time, wrist pain, children with minor complications, and child and parent satisfaction. More bandage-group participants found their treatment convenient (39 children).Removal of casts at home by parents versus at the hospital fracture clinic by clinicians (2 studies, 404 children, mainly buckle fractures)One study (233 children) found full restoration of physical function at four weeks; low-quality evidence. There were five treatment changes (home 4/197; hospital 1/200; 2 studies; very low-quality evidence). One study found no serious adverse effects at six months (288 children). Recovery time and number of children with minor complications were not reported. There was no evidence of a difference in pain at four weeks (233 children); low-quality evidence. One study (80 children) found greater parental satisfaction in the home group; low-quality evidence. One UK study found lower healthcare costs for home removal.Below-elbow versus above-elbow casts for displaced or unstable both-bone fractures (4 studies, 399 children)Short-term physical function data were unavailable but very low-quality evidence indicated less dependency when using below-elbow casts. One study (66 children with minimally displaced both-bone fractures) found little difference in ABILHAND-Kids scores (0 to 42; no problems) (mean scores: below-elbow 40.7; above-elbow 41.8); very low-quality evidence. Overall treatment failure data are unavailable, but nine of the 11 remanipulations or secondary reductions (366 children, 4 studies) were in the above-elbow group; very low-quality evidence. There was no refracture or compartment syndrome at six months (215 children; 2 studies). Recovery time and overall numbers of children with minor complications were not reported. There was little difference in requiring physiotherapy for stiffness (179 children, 2 studies); very low-quality evidence. One study (85 children) found less pain at one week for below-elbow casts; low-quality evidence. One study found treatment with an above-elbow cast cost three times more in Nepal.Surgical fixation with percutaneous wiring and cast immobilisation versus cast immobilisation alone after closed reduction of displaced fractures (5 studies, 323 children)Where reported, above-elbow casts were used. Short-term functional outcome data were unavailable. One study (123 children) reported similar ABILHAND-Kids scores indicating normal physical function at six months (mean scores: surgery 41.9; cast only 41.4); low-quality evidence. There were fewer treatment failures, defined as early or problematic removal of wires or remanipulation for early loss in position, after surgery (surgery 20/124; cast only 41/129; 4 studies; very low-quality evidence). Similarly, there were fewer serious advents after surgery (surgery 28/124; cast only 43/129; 4 studies; very low-quality evidence). Recovery time, wrist pain, and satisfaction were not reported. There was lower referral for physiotherapy for stiffness after surgery (1 study); very low-quality evidence. One USA study found similar treatment costs in both groups. AUTHORS' CONCLUSIONS Where available, the quality of the RCT-based evidence on interventions for treating wrist fractures in children is low or very low. However, there is reassuring evidence of a full return to previous function with no serious adverse events, including refracture, for correctly-diagnosed buckle fractures, whatever the treatment used. The review findings are consistent with the move away from cast immobilisation for these injuries. High-quality evidence is needed to address key treatment uncertainties; notably, some priority topics are already being tested in ongoing multicentre trials, such as FORCE.

Abstract
BACKGROUND Falls in care facilities and hospitals are common events that cause considerable morbidity and mortality for older people. This is an update of a review first published in 2010 and updated in 2012. OBJECTIVES To assess the effects of interventions designed to reduce the incidence of falls in older people in care facilities and hospitals. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (August 2017); Cochrane Central Register of Controlled Trials (2017, Issue 8); and MEDLINE, Embase, CINAHL and trial registers to August 2017. SELECTION CRITERIA Randomised controlled trials of interventions for preventing falls in older people in residential or nursing care facilities, or hospitals. DATA COLLECTION AND ANALYSIS One review author screened abstracts; two review authors screened full-text articles for inclusion. Two review authors independently performed study selection, 'Risk of bias' assessment and data extraction. We calculated rate ratios (RaR) with 95% confidence intervals (CIs) for rate of falls and risk ratios (RRs) and 95% CIs for outcomes such as risk of falling (number of people falling). We pooled results where appropriate. We used GRADE to assess the quality of evidence. MAIN RESULTS Thirty-five new trials (77,869 participants) were included in this update. Overall, we included 95 trials (138,164 participants), 71 (40,374 participants; mean age 84 years; 75% women) in care facilities and 24 (97,790 participants; mean age 78 years; 52% women) in hospitals. The majority of trials were at high risk of bias in one or more domains, mostly relating to lack of blinding. With few exceptions, the quality of evidence for individual interventions in either setting was generally rated as low or very low. Risk of fracture and adverse events were generally poorly reported and, where reported, the evidence was very low-quality, which means that we are uncertain of the estimates. Only the falls outcomes for the main comparisons are reported here.Care facilitiesSeventeen trials compared exercise with control (typically usual care alone). We are uncertain of the effect of exercise on rate of falls (RaR 0.93, 95% CI 0.72 to 1.20; 2002 participants, 10 studies; I² = 76%; very low-quality evidence). Exercise may make little or no difference to the risk of falling (RR 1.02, 95% CI 0.88 to 1.18; 2090 participants, 10 studies; I² = 23%; low-quality evidence).There is low-quality evidence that general medication review (tested in 12 trials) may make little or no difference to the rate of falls (RaR 0.93, 95% CI 0.64 to 1.35; 2409 participants, 6 studies; I² = 93%) or the risk of falling (RR 0.93, 95% CI 0.80 to 1.09; 5139 participants, 6 studies; I² = 48%).There is moderate-quality evidence that vitamin D supplementation (4512 participants, 4 studies) probably reduces the rate of falls (RaR 0.72, 95% CI 0.55 to 0.95; I² = 62%), but probably makes little or no difference to the risk of falling (RR 0.92, 95% CI 0.76 to 1.12; I² = 42%). The population included in these studies had low vitamin D levels.Multifactorial interventions were tested in 13 trials. We are uncertain of the effect of multifactorial interventions on the rate of falls (RaR 0.88, 95% CI 0.66 to 1.18; 3439 participants, 10 studies; I² = 84%; very low-quality evidence). They may make little or no difference to the risk of falling (RR 0.92, 95% CI 0.81 to 1.05; 3153 participants, 9 studies; I² = 42%; low-quality evidence).HospitalsThree trials tested the effect of additional physiotherapy (supervised exercises) in rehabilitation wards (subacute setting). The very low-quality evidence means we are uncertain of the effect of additional physiotherapy on the rate of falls (RaR 0.59, 95% CI 0.26 to 1.34; 215 participants, 2 studies; I² = 0%), or whether it reduces the risk of falling (RR 0.36, 95% CI 0.14 to 0.93; 83 participants, 2 studies; I² = 0%).We are uncertain of the effects of bed and chair sensor alarms in hospitals, tested in two trials (28,649 participants) on rate of falls (RaR 0.60, 95% CI 0.27 to 1.34; I² = 0%; very low-quality evidence) or risk of falling (RR 0.93, 95% CI 0.38 to 2.24; I² = 0%; very low-quality evidence).Multifactorial interventions in hospitals may reduce rate of falls in hospitals (RaR 0.80, 95% CI 0.64 to 1.01; 44,664 participants, 5 studies; I² = 52%). A subgroup analysis by setting suggests the reduction may be more likely in a subacute setting (RaR 0.67, 95% CI 0.54 to 0.83; 3747 participants, 2 studies; I² = 0%; low-quality evidence). We are uncertain of the effect of multifactorial interventions on the risk of falling (RR 0.82, 95% CI 0.62 to 1.09; 39,889 participants; 3 studies; I² = 0%; very low-quality evidence). AUTHORS' CONCLUSIONS In care facilities: we are uncertain of the effect of exercise on rate of falls and it may make little or no difference to the risk of falling. General medication review may make little or no difference to the rate of falls or risk of falling. Vitamin D supplementation probably reduces the rate of falls but not risk of falling. We are uncertain of the effect of multifactorial interventions on the rate of falls; they may make little or no difference to the risk of falling.In hospitals: we are uncertain of the effect of additional physiotherapy on the rate of falls or whether it reduces the risk of falling. We are uncertain of the effect of providing bed sensor alarms on the rate of falls or risk of falling. Multifactorial interventions may reduce rate of falls, although subgroup analysis suggests this may apply mostly to a subacute setting; we are uncertain of the effect of these interventions on risk of falling.

Abstract
BACKGROUND Falls and fall-related injuries are common, particularly in those aged over 65, with around one-third of older people living in the community falling at least once a year. Falls prevention interventions may comprise single component interventions (e.g. exercise), or involve combinations of two or more different types of intervention (e.g. exercise and medication review). Their delivery can broadly be divided into two main groups: 1) multifactorial interventions where component interventions differ based on individual assessment of risk; or 2) multiple component interventions where the same component interventions are provided to all people. OBJECTIVES To assess the effects (benefits and harms) of multifactorial interventions and multiple component interventions for preventing falls in older people living in the community. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature, trial registers and reference lists. Date of search: 12 June 2017. SELECTION CRITERIA Randomised controlled trials, individual or cluster, that evaluated the effects of multifactorial and multiple component interventions on falls in older people living in the community, compared with control (i.e. usual care (no change in usual activities) or attention control (social visits)) or exercise as a single intervention. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, assessed risks of bias and extracted data. We calculated the rate ratio (RaR) with 95% confidence intervals (CIs) for rate of falls. For dichotomous outcomes we used risk ratios (RRs) and 95% CIs. For continuous outcomes, we used the standardised mean difference (SMD) with 95% CIs. We pooled data using the random-effects model. We used the GRADE approach to assess the quality of the evidence. MAIN RESULTS We included 62 trials involving 19,935 older people living in the community. The median trial size was 248 participants. Most trials included more women than men. The mean ages in trials ranged from 62 to 85 years (median 77 years). Most trials (43 trials) reported follow-up of 12 months or over. We assessed most trials at unclear or high risk of bias in one or more domains.Forty-four trials assessed multifactorial interventions and 18 assessed multiple component interventions. (I2 not reported if = 0%).Multifactorial interventions versus usual care or attention controlThis comparison was made in 43 trials. Commonly-applied or recommended interventions after assessment of each participant's risk profile were exercise, environment or assistive technologies, medication review and psychological interventions. Multifactorial interventions may reduce the rate of falls compared with control: rate ratio (RaR) 0.77, 95% CI 0.67 to 0.87; 19 trials; 5853 participants; I2 = 88%; low-quality evidence. Thus if 1000 people were followed over one year, the number of falls may be 1784 (95% CI 1553 to 2016) after multifactorial intervention versus 2317 after usual care or attention control. There was low-quality evidence of little or no difference in the risks of: falling (i.e. people sustaining one or more fall) (RR 0.96, 95% CI 0.90 to 1.03; 29 trials; 9637 participants; I2 = 60%); recurrent falls (RR 0.87, 95% CI 0.74 to 1.03; 12 trials; 3368 participants; I2 = 53%); fall-related hospital admission (RR 1.00, 95% CI 0.92 to 1.07; 15 trials; 5227 participants); requiring medical attention (RR 0.91, 95% CI 0.75 to 1.10; 8 trials; 3078 participants). There is low-quality evidence that multifactorial interventions may reduce the risk of fall-related fractures (RR 0.73, 95% CI 0.53 to 1.01; 9 trials; 2850 participants) and may slightly improve health-related quality of life but not noticeably (SMD 0.19, 95% CI 0.03 to 0.35; 9 trials; 2373 participants; I2 = 70%). Of three trials reporting on adverse events, one found none, and two reported 12 participants with self-limiting musculoskeletal symptoms in total.Multifactorial interventions versus exerciseVery low-quality evidence from one small trial of 51 recently-discharged orthopaedic patients means that we are uncertain of the effects on rate of falls or risk of falling of multifactorial interventions versus exercise alone. Other fall-related outcomes were not assessed.Multiple component interventions versus usual care or attention controlThe 17 trials that make this comparison usually included exercise and another component, commonly education or home-hazard assessment. There is moderate-quality evidence that multiple interventions probably reduce the rate of falls (RaR 0.74, 95% CI 0.60 to 0.91; 6 trials; 1085 participants; I2 = 45%) and risk of falls (RR 0.82, 95% CI 0.74 to 0.90; 11 trials; 1980 participants). There is low-quality evidence that multiple interventions may reduce the risk of recurrent falls, although a small increase cannot be ruled out (RR 0.81, 95% CI 0.63 to 1.05; 4 trials; 662 participants). Very low-quality evidence means that we are uncertain of the effects of multiple component interventions on the risk of fall-related fractures (2 trials) or fall-related hospital admission (1 trial). There is low-quality evidence that multiple interventions may have little or no effect on the risk of requiring medical attention (RR 0.95, 95% CI 0.67 to 1.35; 1 trial; 291 participants); conversely they may slightly improve health-related quality of life (SMD 0.77, 95% CI 0.16 to 1.39; 4 trials; 391 participants; I2 = 88%). Of seven trials reporting on adverse events, five found none, and six minor adverse events were reported in two.Multiple component interventions versus exerciseThis comparison was tested in five trials. There is low-quality evidence of little or no difference between the two interventions in rate of falls (1 trial) and risk of falling (RR 0.93, 95% CI 0.78 to 1.10; 3 trials; 863 participants) and very low-quality evidence, meaning we are uncertain of the effects on hospital admission (1 trial). One trial reported two cases of minor joint pain. Other falls outcomes were not reported. AUTHORS' CONCLUSIONS Multifactorial interventions may reduce the rate of falls compared with usual care or attention control. However, there may be little or no effect on other fall-related outcomes. Multiple component interventions, usually including exercise, may reduce the rate of falls and risk of falling compared with usual care or attention control.

Abstract
BACKGROUND Anterior cruciate ligament (ACL) tears are serious knee injuries that are frequently treated surgically in the form of arthroscopically assisted reconstruction with grafts from the patella or hamstrings tendons. We reviewed the evidence for the choice of arthroscopically assisted ACL reconstruction technique in terms of whether it should involve one incision (femoral tunnel drilled from inside the knee joint under arthroscopic visualisation) or two incisions (femoral tunnel drilled from outside to inside the knee joint). OBJECTIVES To assess the effects (benefits and harms) of one-incision versus two-incision techniques for arthroscopically assisted ACL reconstruction in adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Latin American and Caribbean Health Sciences (LILACS), the World Health Organization International Clinical Trials Registry Platform, ClinicalTrials.gov, reference lists, and conference abstracts. The date of the search was 16 August 2017. SELECTION CRITERIA Randomised and quasi-randomised controlled clinical trials evaluating one-incision versus two-incision techniques for arthroscopically assisted ACL reconstruction in adults. DATA COLLECTION AND ANALYSIS Two review authors independently searched and selected studies, and extracted data and assessed the risk of bias of the eligible studies. We undertook limited pooling of data using the fixed-effect model. MAIN RESULTS We included five trials (four randomised and one quasi-randomised) evaluating a total of 320 participants who were mainly in their 20s. All participants underwent ACL reconstruction with patella tendon grafts. All five included trials were at a high risk of bias, particularly performance bias. Based on these limitations and the insufficiency of the available data resulting in imprecision of effect estimates, we judged the quality of the evidence as very low for all outcomes. This means that we are uncertain of the findings of the review.We found very low-quality evidence of no clinically important differences between the two techniques in self reported knee function, measured using the Lysholm knee score (scale 0 to 100: best outcome), at short-term (3 months) (mean difference (MD) 2.73 favours one-incision technique, 95% confidence interval (CI) -2.70 to 8.15; 79 participants, 2 studies), intermediate-term (12 months) (MD -3.68 favours two-incision technique, 95% CI -6.61 to -0.75; 79 participants, 2 studies), and long-term follow-up. The data available for long-term follow-up (2 to 5 years) was expressed in terms of the numbers of participants with excellent Lysholm scores (90 points or more); we found no difference between the two groups (42/45 versus 36/40; risk ratio (RR) 1.04, 95% CI 0.91 to 1.18; 1 study). There were no data for quality of life measures or for overall numbers of participants incurring an adverse event. We found very low-quality evidence of little between-group differences in individual adverse events such as infection, knee stiffness, reoperation, and graft failure.We found very low-quality evidence from one study (59 participants) of little difference between the two groups in activity levels measured using Tegner scores (scale 0 to 10: highest sport activity) at two years (MD -0.80 favours two-incision technique, 95% CI -1.90 to 0.30). There was very low-quality evidence from four studies of minimal between-group difference in the number of participants with normal or nearly normal objectively measured knee function (International Knee Documentation Committee objective assessment grading) at intermediate follow-up (means 12 to 28 months): 56/78 versus 63/89; RR 1.01, 95% CI 0.85 to 1.21; 167 participants). AUTHORS' CONCLUSIONS The very low-quality and often absent evidence means that we are uncertain whether one-incision arthroscopically assisted ACL reconstruction techniques yield better, worse, or equivalent results compared with two-incision techniques in terms of short-, intermediate-, or long-term subjective function, quality of life, adverse outcomes, activity levels, and objectively rated knee function. The evidence was available only for single-bundle ACL reconstruction using patella tendon grafts.When considering priorities for high-quality randomised trials on techniques for ACL reconstruction, it is important to note the insufficiency of the evidence available to inform this key comparison.

Abstract
BACKGROUND Muscle soreness typically occurs after intense exercise, unaccustomed exercise or actions that involve eccentric contractions where the muscle lengthens while under tension. It peaks between 24 and 72 hours after the initial bout of exercise. Many people take antioxidant supplements or antioxidant-enriched foods before and after exercise in the belief that these will prevent or reduce muscle soreness after exercise. OBJECTIVES To assess the effects (benefits and harms) of antioxidant supplements and antioxidant-enriched foods for preventing and reducing the severity and duration of delayed onset muscle soreness following exercise. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, SPORTDiscus, trial registers, reference lists of articles and conference proceedings up to February 2017. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials investigating the effects of all forms of antioxidant supplementation including specific antioxidant supplements (e.g. tablets, powders, concentrates) and antioxidant-enriched foods or diets on preventing or reducing delayed onset muscle soreness (DOMS). We excluded studies where antioxidant supplementation was combined with another supplement. DATA COLLECTION AND ANALYSIS Two review authors independently screened search results, assessed risk of bias and extracted data from included trials using a pre-piloted form. Where appropriate, we pooled results of comparable trials, generally using the random-effects model. The outcomes selected for presentation in the 'Summary of findings' table were muscle soreness, collected at times up to 6 hours, 24, 48, 72 and 96 hours post-exercise, subjective recovery and adverse effects. We assessed the quality of the evidence using GRADE. MAIN RESULTS Fifty randomised, placebo-controlled trials were included, 12 of which used a cross-over design. Of the 1089 participants, 961 (88.2%) were male and 128 (11.8%) were female. The age range for participants was between 16 and 55 years and training status varied from sedentary to moderately trained. The trials were heterogeneous, including the timing (pre-exercise or post-exercise), frequency, dose, duration and type of antioxidant supplementation, and the type of preceding exercise. All studies used an antioxidant dosage higher than the recommended daily amount. The majority of trials (47) had design features that carried a high risk of bias due to selective reporting and poorly described allocation concealment, potentially limiting the reliability of their findings.We tested only one comparison: antioxidant supplements versus control (placebo). No studies compared high-dose versus low-dose, where the low-dose supplementation was within normal or recommended levels for the antioxidant involved.Pooled results for muscle soreness indicated a small difference in favour of antioxidant supplementation after DOMS-inducing exercise at all main follow-ups: up to 6 hours (standardised mean difference (SMD) -0.30, 95% confidence interval (CI) -0.56 to -0.04; 525 participants, 21 studies; low-quality evidence); at 24 hours (SMD -0.13, 95% CI -0.27 to 0.00; 936 participants, 41 studies; moderate-quality evidence); at 48 hours (SMD -0.24, 95% CI -0.42 to -0.07; 1047 participants, 45 studies; low-quality evidence); at 72 hours (SMD -0.19, 95% CI -0.38 to -0.00; 657 participants, 28 studies; moderate-quality evidence), and little difference at 96 hours (SMD -0.05, 95% CI -0.29 to 0.19; 436 participants, 17 studies; low-quality evidence). When we rescaled to a 0 to 10 cm scale in order to quantify the actual difference between groups, we found that the 95% CIs for all five follow-up times were all well below the minimal important difference of 1.4 cm: up to 6 hours (MD -0.52, 95% CI -0.95 to -0.08); at 24 hours (MD -0.17, 95% CI -0.42 to 0.07); at 48 hours (MD -0.41, 95% CI -0.69 to -0.12); at 72 hours (MD -0.29, 95% CI -0.59 to 0.02); and at 96 hours (MD -0.03, 95% CI -0.43 to 0.37). Thus, the effect sizes suggesting less muscle soreness with antioxidant supplementation were very unlikely to equate to meaningful or important differences in practice. Neither of our subgroup analyses to examine for differences in effect according to type of DOMS-inducing exercise (mechanical versus whole body aerobic) or according to funding source confirmed subgroup differences. Sensitivity analyses excluding cross-over trials showed that their inclusion had no important impact on results.None of the 50 included trials measured subjective recovery (return to previous activities without signs or symptoms).There is very little evidence regarding the potential adverse effects of taking antioxidant supplements as this outcome was reported in only nine trials (216 participants). From the studies that did report adverse effects, two of the nine trials found adverse effects. All six participants in the antioxidant group of one trial had diarrhoea and four of these also had mild indigestion; these are well-known side effects of the particular antioxidant used in this trial. One of 26 participants in a second trial had mild gastrointestinal distress. AUTHORS' CONCLUSIONS There is moderate to low-quality evidence that high dose antioxidant supplementation does not result in a clinically relevant reduction of muscle soreness after exercise at up to 6 hours or at 24, 48, 72 and 96 hours after exercise. There is no evidence available on subjective recovery and only limited evidence on the adverse effects of taking antioxidant supplements. The findings of, and messages from, this review provide an opportunity for researchers and other stakeholders to come together and consider what are the priorities, and underlying justifications, for future research in this area.

Abstract
BACKGROUND Patellofemoral pain syndrome, now generally referred to as patellofemoral pain (PFP), is one of the most common orthopaedic disorders, characterised by pain in the anterior or retropatellar knee region. Neuromuscular electrical stimulation (NMES) has been proposed generally as a complementary treatment, associated with other interventions such as exercise, or as a single treatment to increase muscle force, reduce knee pain, and improve function. OBJECTIVES To assess the effects (benefits and harms) of neuromuscular electrical stimulation for people with patellofemoral pain. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PEDro, CINAHL, SPORTDiscus, AMED, LILACS, trial registers, conference abstracts, and reference lists. We carried out the search in May 2017. SELECTION CRITERIA We included randomised controlled clinical trials that evaluated the use of NMES for people with PFP. DATA COLLECTION AND ANALYSIS Two review authors independently performed the process of study selection, data extraction, and 'Risk of bias' assessment in duplicate. The primary outcomes were knee pain, knee function, and adverse events. The timing of outcome measurements was up to three months (short term), three to 12 months (medium term), and 12 months and above from trial entry (long term). We calculated risk ratios for dichotomous data and mean differences or standardised mean differences for continuous data. Where appropriate, we pooled data using the fixed-effect model. MAIN RESULTS We included eight randomised clinical trials, reporting results for 345 participants with PFP. The mean ages of trial populations ranged from 25 to 43 years, and the majority (53% to 100%) of participants were female. There was a wide duration of symptoms, with the minimum duration of symptoms for trial inclusion ranging from one to six months. In addition to the study inclusion criteria, studies varied widely in the characteristics of the NMES and its application, and associated co-interventions. We assessed all trials as at high risk of bias in at least one domain, particularly blinding and incomplete outcome data. The results of a laboratory-based trial reporting knee pain immediately after a single 15-minute session of NMES are not reported here as these are of questionable clinical relevance. The seven remaining trials provided evidence for three comparisons. We assessed the overall quality of the evidence, using GRADE, for all primary outcomes for all comparisons as very low, thus we are very unsure of the findings.Four studies compared NMES plus exercise versus exercise alone. Patellar taping was applied as well as exercise to all participants of one study, and patellar taping and ice were also applied in another study. Each trial tested a different multiple-session NMES programme. Pooled data from three studies (118 participants) provided very low-quality evidence that NMES is associated with reduced pain at the end of treatment (ranging from 3 to 12 weeks): mean difference -1.63, 95% confidence interval (CI) -2.23 to -1.02; visual analogue scale (VAS) 0 to 10; higher scores = worse pain. However, this result may not be clinically relevant since the minimal clinically important difference for VAS during activities (1.5 to 2.0, out of 10 points) lies within the 95% CI. We found very low-quality evidence from pooled data from two trials of little effect of NMES on knee function, as measured by two knee function rating systems. We found inconclusive and very low-quality evidence from one trial (29 participants) of little effect of NMES on pain and function at one-year follow-up. None of the four trials reported on adverse effects of treatment.One study (94 participants) compared NMES, applied four hours per day on a daily basis for four weeks, with two types of exercises (isometric and isokinetic). The study did not report on knee pain or adverse events. The study provided very low-quality evidence of no important difference between the two groups in knee function at the end of the four-week treatment. Of note is the potentially onerous NMES schedule in this study, which does not correspond to that typically used in clinical practice.Two studies compared different types of NMES. Simultaneously delivered high-low frequencies NMES was compared with sequentially delivered high-low frequencies NMES in one trial (14 participants) and with fixed frequency NMES in the second trial (64 participants). The studies provided very low-quality evidence of no important differences at the end of the six-week treatment programme between the simultaneous frequencies NMES and the two other NMES programmes in overall knee pain, knee function, or in quadriceps fatigue (an adverse event). AUTHORS' CONCLUSIONS This review found insufficient and inconclusive evidence from randomised controlled trials to inform on the role of NMES for treating people with PFP in current clinical practice. The very low-quality evidence available means that we are uncertain whether or not a multiple-session programme of NMES combined with exercise over several weeks versus exercise alone results in clinically important differences in knee pain and function at the end of the treatment period or at one year. There were no data on adverse effects such as muscle fatigue and discomfort. High-quality randomised clinical trials are needed to inform on the use of NMES for people with PFP. However, professional and stakeholder consensus is required on prioritisation of the research questions for interventions for treating people with PFP, including on the NMES treatment protocol for trials testing NMES.

Abstract
BACKGROUND Pulled elbow (nursemaid's elbow) is a common injury in young children. It often results from a sudden pull on the arm, usually by an adult or taller person, which pulls the radius through the annular ligament, resulting in subluxation (partial dislocation) of the radial head. It can also be caused by a fall or twist. The child experiences sudden acute pain and loss of function in the affected arm. Pulled elbow is usually treated by manual reduction of the subluxed radial head. Various manoeuvres can be applied; most commonly, supination of the forearm, often combined with flexion, and (hyper-)pronation. It is unclear which is most successful. This is an update of a Cochrane review first published in 2009 and last updated in 2011. OBJECTIVES To compare the effects (benefits and harms) of the different methods used to manipulate pulled elbow in young children. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, CINAHL, LILACS, PEDro, clinical trial registers and reference lists of articles. Date of last search: September 2016. SELECTION CRITERIA Randomised or quasi-randomised controlled clinical trials evaluating manipulative interventions for pulled elbow were included. Our primary outcome was failure at the first attempt, necessitating further treatment. DATA COLLECTION AND ANALYSIS Two review authors independently evaluated trials for inclusion, assessed risk of bias, and extracted data. We pooled data using a fixed-effect model. MAIN RESULTS Overall, nine trials with 906 children (all younger than seven years old and 58% of whom were female) were included, of which five trials were newly identified in this update. Eight trials were performed in emergency departments or ambulatory care centres, and one was performed in a tertiary paediatric orthopaedic unit. Four trials were conducted in the USA, three in Turkey, one in Iran, and one in Spain. Five trials were at high risk of selection bias because allocation was not concealed and all trials were at high risk of detection bias due to the lack of assessor blinding. Eight trials compared hyperpronation with supination-flexion. We found low-quality evidence that hyperpronation resulted in less failure at first attempt than supination-flexion (9.2% versus 26.4%, risk ratio (RR) 0.35; 95% confidence interval (CI) 0.25 to 0.50; 811 participants, 8 studies). Based on an illustrative risk of 268 failures at first attempt per 1000 children treated using supination-flexion, this amounted to 174 fewer failures per 1000 children treated using hyperpronation (95% CI 134 to 201 fewer). Based on risk differences data, we also estimated a number needed to treat of 6 (95% CI 5 to 8); this means that six children would need to be treated with the hyperpronation method rather than the supination-flexion method to avoid one additional failure at the first attempt.The very low-quality evidence (from four studies) for pain during or after manipulation means that it is uncertain whether there is or is not a difference between pronation and supination-flexion. There was very low-quality evidence from six studies that repeat pronation may be more effective than repeat supination-flexion for the second attempt after initial failure. The remaining outcomes were either not reported (adverse effects, recurrence) or unsuitable for pooling (ultimate failure). Ultimate failure, reported for the overall population only because of the differences in the study protocols with respect to what to do after the first attempt failed, ranged from no ultimate failures in two studies to six failures (4.1% of 148 episodes) in one study.One trial compared supination-extension versus supination-flexion. It provided very low-quality evidence (downgraded three levels for very serious risk of bias and serious imprecision) of no clear difference in failure at first attempt between the two methods. AUTHORS' CONCLUSIONS There was low-quality evidence from eight small trials that the pronation method may be more effective at first attempt than the supination method for manipulating pulled elbow in young children. For other outcomes, no conclusions could be drawn either because of very low-quality evidence or the outcomes not being reported. We suggest that a high-quality randomised clinical trial comparing hyperpronation and supination-flexion is required to provide definitive evidence. We recommend that this is preceded by a survey among clinicians to establish the extent of clinical equipoise and to optimise the study design and recruitment.

Abstract
BACKGROUND Plantar heel pain, commonly resulting from plantar fasciitis, often results in significant morbidity. Treatment options include nonsteroidal anti-inflammatory drugs (NSAIDs), orthoses, physical therapy, physical agents (e.g. extracorporeal shock wave therapy (ESWT), laser) and invasive procedures including steroid injections. OBJECTIVES To assess the effects (benefits and harms) of injected corticosteroids for treating plantar heel pain in adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials (the Cochrane Library), MEDLINE, Embase, CINAHL, clinical trials registries and conference proceedings. Latest search: 27 March 2017. SELECTION CRITERIA Randomised and quasi-randomised trials of corticosteroid injections in the treatment of plantar heel pain in adults were eligible for inclusion. DATA COLLECTION AND ANALYSIS At least two review authors independently selected studies, assessed risk of bias and extracted data. We calculated risk ratios (RRs) for dichotomous outcomes and mean differences (MDs) for continuous outcome measures. We used a fixed-effect model unless heterogeneity was significant, when a random-effects model was considered. We assessed the overall quality of evidence for individual outcomes using the GRADE approach. MAIN RESULTS We included a total of 39 studies (36 randomised controlled trials (RCTs) and 3 quasi-RCTs) that involved a total of 2492 adults. Most studies were small (median = 59 participants). Participants' mean ages ranged from 34 years to 59 years. When reported, most participants had heel pain for several months. The trials were usually conducted in outpatient specialty clinics of tertiary care hospitals in 17 countries. Steroid injection was given with a local anaesthetic agent in 34 trials. Follow-up was from one month to over two years. With one exception, trials were assessed at high risk of bias in one or more domains, mostly relating to lack of blinding, including lack of confirmation of allocation concealment. With two exceptions, we rated the available evidence as very low quality, implying in each case that we are 'very uncertain about the estimate'.The 39 trials covered 18 comparisons, with six of the seven trials with three or four groups providing evidence towards two comparisons.Eight trials (724 participants) compared steroid injection versus placebo or no treatment. Steroid injection may lead to lower heel pain visual analogue scores (VAS) (0 to 100; higher scores = worse pain) in the short-term (< 1 month) (MD -6.38, 95% CI -11.13 to -1.64; 350 participants; 5 studies; I² = 65%; low quality evidence). Based on a minimal clinically significant difference (MCID) of 8 for average heel pain, the 95% CI includes a marginal clinical benefit. This potential benefit was diminished when data were restricted to three placebo-controlled trials. Steroid injection made no difference to average heel pain in the medium-term (1 to 6 months follow-up) (MD -3.47, 95% CI -8.43 to 1.48; 382 participants; 6 studies; I² = 40%; low quality evidence). There was very low quality evidence for no effect on function in the medium-term and for an absence of serious adverse events (219 participants, 4 studies). No studies reported on other adverse events, such as post-injection pain, and on return to previous activity. There was very low quality evidence for fewer treatment failures (defined variously as persistent heel pain at 8 weeks, steroid injection at 12 weeks, and unrelieved pain at 6 months) after steroid injection.The available evidence for other comparisons was rated as very low quality. We are therefore very uncertain of the estimates for the relative effects on people with heel pain of steroids compared with other interventions in:1. Tibial nerve block with anaesthetic (2 trials); orthoses (4 trials); oral NSAIDs (2 trials); and intensive physiotherapy (1 trial).2. Physical modalities: ESWT (5 trials); laser (2 trials); and radiation therapy (1 trial).3. Other invasive procedures: locally injectable NSAID (1 trial); platelet-rich plasma injections (5 trials); autologous blood injections (2 trials); botulinum toxin injections (2 trials); cryopreserved human amniotic membrane injection (1 trial); localised peppering with a needle (1 trial); dry needling (1 trial); and mini scalpel needle release (1 trial).We are also uncertain about the estimates from trials testing different techniques of local steroid injection: ultrasonography-guided versus palpation-guided (5 trials); and scintigraphy-guided versus palpation-guided (1 trial).An exploratory analysis involving pooling data from 21 trials reporting on adverse events revealed two ruptures of plantar fascia (reported in 1 trial) and three injection site infections (reported in 2 trials) in 699 participants allocated to steroid injection study arms. Five trials reported a total of 27 participants with less serious short-term adverse events in the 699 participants allocated steroid injection study arms. Reported treatments were analgesia, ice or both. Given the high risk of selective reporting for these outcomes and imprecision, this evidence was rated at very low quality. AUTHORS' CONCLUSIONS We found low quality evidence that local steroid injections compared with placebo or no treatment may slightly reduce heel pain up to one month but not subsequently. The available evidence for other outcomes of this comparison was very low quality. Where available, the evidence from comparisons of steroid injections with other interventions used to treat heel pain and of different methods of guiding the injection was also very low quality. Although serious adverse events relating to steroid injection were rare, these were under-reported and a higher risk cannot be ruled out.Further research should focus on establishing the effects (benefits and harms) of injected steroids compared with placebo in typical clinical settings, subsequent to a course of unsuccessful conservative therapy. Ideally, this should be preceded by research, including patient involvement, aimed to obtain consensus on the priority questions for treating plantar heel pain.

Abstract
BACKGROUND Simple bone cysts, also known as a unicameral bone cysts or solitary bone cysts, are the most common type of benign bone lesion in growing children. Cysts may lead to repeated pathological fracture (fracture that occurs in an area of bone weakened by a disease process). Occasionally, these fractures may result in symptomatic malunion. The main goals of treatment are to decrease the risk of pathological fracture, enhance cyst healing and resolve pain. Despite the numerous treatment methods that have been used for simple bone cysts in long bones of children, there is no consensus on the best procedure. This is an update of a Cochrane review first published in 2014. OBJECTIVES To assess the effects (benefits and harms) of interventions for treating simple bone cysts in the long bones of children, including adolescents.We intended the following main comparisons: invasive (e.g. injections, curettage, surgical fixation) versus non-invasive interventions (e.g. observation, plaster cast, restricted activity); different categories of invasive interventions (i.e. injections, curettage, drilling holes and decompression, surgical fixation and continued decompression); different variations of each category of invasive intervention (e.g. different injection substances: autologous bone marrow versus steroid). SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, the China National Knowledge Infrastructure Platform, trial registers, conference proceedings and reference lists. Date of last search: April 2016. SELECTION CRITERIA Randomised and quasi-randomised controlled trials evaluating methods for treating simple bone cysts in the long bones of children. DATA COLLECTION AND ANALYSIS Two review authors independently screened search results and performed study selection. We resolved differences in opinion between review authors by discussion and by consulting a third review author. Two review authors independently assessed risk of bias and data extraction. We summarised data using risk ratios (RRs) or mean differences (MDs), as appropriate, and 95% confidence intervals (CIs). We used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system to assess the overall quality of the evidence. MAIN RESULTS In this update in 2017, we did not identify any new randomised controlled trials (RCT) for inclusion. We identified one ongoing trial that we are likely to include in a future update. Accordingly, our results are unchanged. The only included trial is a multicentre RCT conducted at 24 locations in North America and India that compared bone marrow injection with steroid (methylprednisolone acetate) injection for treating simple bone cysts. Up to three injections were planned for participants in each group. The trial involved 90 children (mean age 9.5 years) and presented results for 77 children at two-year follow-up. Although the trial had secure allocation concealment, it was at high risk of performance bias and from major imbalances in baseline characteristics. Reflecting these study limitations, we downgraded the quality of evidence by two levels to 'low' for most outcomes, meaning that we are unsure about the estimates of effect. For outcomes where there was serious imprecision, we downgraded the quality of evidence by a further level to 'very low'.The trial provided very low quality evidence that fewer children in the bone marrow injection group had radiographically assessed healing of bone cysts at two years than in the steroid injection group (9/39 versus 16/38; RR 0.55 favouring steroid injection, 95% CI 0.28 to 1.09). However, the result was uncertain and may be compatible with no difference or small benefit favouring bone marrow injection. Based on an illustrative success rate of 421 children with healed bone cysts per 1000 children treated with steroid injections, this equates to 189 fewer (95% CI 303 fewer to 38 more) children with healed bone cysts per 1000 children treated with bone marrow injections. There was low quality evidence of a lack of difference between the two interventions at two years in functional outcome, based on the Activity Scale for Kids function score (0 to 100; higher scores equate to better outcome: MD -0.90; 95% CI -4.26 to 2.46) or in pain assessed using the Oucher pain score. There was very low quality evidence of a lack of differences between the two interventions for adverse events: subsequent pathological fracture (9/39 versus 11/38; RR 0.80, 95% CI 0.37 to 1.70) or superficial infection (two cases in the bone marrow group). Recurrence of bone cyst, unacceptable malunion, return to normal activities, and participant satisfaction were not reported. AUTHORS' CONCLUSIONS The available evidence is insufficient to determine the relative effects of bone marrow versus steroid injections, although the bone marrow injections are more invasive. Noteably, the rate of radiographically assessed healing of the bone cyst at two years was well under 50% for both interventions. Overall, there is a lack of evidence to determine the best method for treating simple bone cysts in the long bones of children. Further RCTs of sufficient size and quality are needed to guide clinical practice.

Abstract
BACKGROUND Clavicle (collarbone) fractures account for around 4% of all fractures. Most (76%) clavicle fractures involve the middle-third section of the clavicle. Treatment of these fractures is usually non-surgical (conservative). Commonly used treatments are arm slings, strapping and figure-of-eight bandages.This is an update of a Cochrane review first published in 2009 and updated in 2014. OBJECTIVES To evaluate the effects (benefits and harms) of different methods for conservative (non-operative) treatment for acute (treated soon after injury) middle third clavicle fractures in adolescents and adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE (from 1966), Embase (from 1980), LILACS (from 1982), trial registers, orthopaedic proceedings and reference lists of articles. We applied no language or publication restrictions. The date of the last search was 5 January 2016. SELECTION CRITERIA Randomised and quasi-randomised controlled trials testing conservative interventions for treating adolescents and adults with acute middle third clavicle fractures. The primary outcomes were shoulder function or disability, pain and treatment failure. DATA COLLECTION AND ANALYSIS For this update, two review authors selected eligible trials, independently assessed risk of bias and cross-checked data extraction. We calculated risk ratios and 95% confidence intervals for dichotomous variables, and mean differences and 95% confidence intervals for continuous variables. There was very limited pooling of data. MAIN RESULTS We included four trials in this review with 416 participants, who were aged 14 years or above. One new trial was included in this update.Very low quality evidence was available from three trials (296 participants) that compared the figure-of-eight bandage with an arm sling for treating acute middle third clavicle fractures. The three trials were underpowered and compromised by poor methodology. Shoulder function was assessed in different ways in the three trials (data for 51, 61 and 152 participants); each trial provided very low quality evidence of similar shoulder function in the two groups. Pooled data from two trials (203 participants) showed no clinical difference between groups after two weeks in pain (visual analogue scale: 0 (no pain) to 10 (worst pain); mean difference (MD) 0.43, 95% confidence interval (CI) -0.35 to 1.21; I² = 74%; very low quality evidence). A third trial (61 participants) provided very low quality evidence based on a non-validated scoring system of more pain and discomfort during the course of treatment in the figure-of-eight group. Treatment failure, measured in terms of subsequent surgery, was not reported in two trials; the third trial (152 participants) reported one participant in the arm sling group had surgery for secondary plexus nerve palsy. There was very low quality evidence from one trial (148 participants) of little difference in time to clinical fracture healing (MD 0.2 weeks, 95% CI -0.11 to 0.51); data from four non-symptomatic non-unions in the figure-of-eight group were not included. The very low evidence quality data for individual adverse outcomes (poor cosmetic appearance; change in allocated treatment due to pain and discomfort, worsened fracture position on healing; shortening > 15 mm; non-symptomatic non-union and permanent pain) did not confirm a difference between the two groups. There was no clear between group difference in the time to return to school or work activities (MD -0.12 weeks, 95% CI -0.69 to 0.45; 176 participants; very low quality evidence).Moderate quality evidence was available from one trial (120 participants; reporting data for 101 participants), which evaluated therapeutic ultrasound. This trial was at low risk of bias but was underpowered and did not report on shoulder function or quality of life. The trial found no evidence of a difference between low-intensity pulsed ultrasound and placebo in pain, treatment failure (subsequent surgery: 6/52 versus 5/49; RR 1.13, 95% CI 0.37 to 3.47), the time to clinical fracture healing (MD -0.32 days, 95% CI -5.85 to 5.21), adverse events (one case of skin irritation was reported in each group) or time to resume previous activities. AUTHORS' CONCLUSIONS The current evidence available from randomised controlled trials is insufficient to determine which methods of conservative treatment are the most appropriate for acute middle third clavicle fractures in adolescents and adults. Further research is warranted.

Abstract
BACKGROUND Older people with hip fractures are often malnourished at the time of fracture, and subsequently have poor food intake. This is an update of a Cochrane review first published in 2000, and previously updated in 2010. OBJECTIVES To review the effects (benefits and harms) of nutritional interventions in older people recovering from hip fracture. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, CENTRAL, MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, Embase, CAB Abstracts, CINAHL, trial registers and reference lists. The search was last run in November 2015. SELECTION CRITERIA Randomised and quasi-randomised controlled trials of nutritional interventions for people aged over 65 years with hip fracture where the interventions were started within the first month after hip fracture. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, extracted data and assessed risk of bias. Where possible, we pooled data for primary outcomes which were: all cause mortality; morbidity; postoperative complications (e.g. wound infections, pressure sores, deep venous thromboses, respiratory and urinary infections, cardiovascular events); and 'unfavourable outcome' defined as the number of trial participants who died plus the number of survivors with complications. We also pooled data for adverse events such as diarrhoea. MAIN RESULTS We included 41 trials involving 3881 participants. Outcome data were limited and risk of bias assessment showed that trials were often methodologically flawed, with less than half of trials at low risk of bias for allocation concealment, incomplete outcome data, or selective reporting of outcomes. The available evidence was judged of either low or very low quality indicating that we were uncertain or very uncertain about the estimates.Eighteen trials evaluated oral multinutrient feeds that provided non-protein energy, protein, vitamins and minerals. There was low-quality evidence that oral feeds had little effect on mortality (24/486 versus 31/481; risk ratio (RR) 0.81 favouring supplementation, 95% confidence interval (CI) 0.49 to 1.32; 15 trials). Thirteen trials evaluated the effect of oral multinutrient feeds on complications (e.g. pressure sore, infection, venous thrombosis, pulmonary embolism, confusion). There was low-quality evidence that the number of participants with complications may be reduced with oral multinutrient feeds (123/370 versus 157/367; RR 0.71, 95% CI 0.59 to 0.86; 11 trials). Based on very low-quality evidence from six studies (334 participants), oral supplements may result in lower numbers with 'unfavourable outcome' (death or complications): RR 0.67, 95% CI 0.51 to 0.89. There was very low-quality evidence for six studies (442 participants) that oral supplementation did not result in an increased incidence of vomiting and diarrhoea (RR 0.99, 95% CI 0.47 to 2.05).Only very low-quality evidence was available from the four trials examining nasogastric multinutrient feeding. Pooled data from three heterogeneous trials showed no evidence of an effect of supplementation on mortality (14/142 versus 14/138; RR 0.99, 95% CI 0.50 to 1.97). One trial (18 participants) found no difference in complications. None reported on unfavourable outcome. Nasogastric feeding was poorly tolerated. One study reported no cases of aspiration pneumonia.There is very low-quality evidence from one trial (57 participants, mainly men) of no evidence for an effect of tube feeding followed by oral supplementation on mortality or complications. Tube feeding, however, was poorly tolerated.There is very low-quality evidence from one trial (80 participants) that a combination of intravenous feeding and oral supplements may not affect mortality but could reduce complications. However, this expensive intervention is usually reserved for people with non-functioning gastrointestinal tracts, which is unlikely in this trial.Four trials tested increasing protein intake in an oral feed. These provided low-quality evidence for no clear effect of increased protein intake on mortality (30/181 versus 21/180; RR 1.42, 95% CI 0.85 to 2.37; 4 trials) or number of participants with complications but very low-quality and contradictory evidence of a reduction in unfavourable outcomes (66/113 versus 82/110; RR 0.78, 95% CI 0.65 to 0.95; 2 trials). There was no evidence of an effect on adverse events such as diarrhoea.Trials testing intravenous vitamin B1 and other water soluble vitamins, oral 1-alpha-hydroxycholecalciferol (vitamin D), high dose bolus vitamin D, different oral doses or sources of vitamin D, intravenous or oral iron, ornithine alpha-ketoglutarate versus an isonitrogenous peptide supplement, taurine versus placebo, and a supplement with vitamins, minerals and amino acids, provided low- or very low-quality evidence of no clear effect on mortality or complications, where reported.Based on low-quality evidence, one trial evaluating the use of dietetic assistants to help with feeding indicated that this intervention may reduce mortality (19/145 versus 36/157; RR 0.57, 95% CI 0.34 to 0.95) but not the number of participants with complications (79/130 versus 84/125). AUTHORS' CONCLUSIONS There is low-quality evidence that oral multinutrient supplements started before or soon after surgery may prevent complications within the first 12 months after hip fracture, but that they have no clear effect on mortality. There is very low-quality evidence that oral supplements may reduce 'unfavourable outcome' (death or complications) and that they do not result in an increased incidence of vomiting and diarrhoea. Adequately sized randomised trials with robust methodology are required. In particular, the role of dietetic assistants, and peripheral venous feeding or nasogastric feeding in very malnourished people require further evaluation.

Abstract
BACKGROUND Cartilage defects of the knee are often debilitating and predispose to osteoarthritis. Microfracture, drilling, mosaicplasty, and allograft transplantation are four surgical treatment options that are increasingly performed worldwide. We set out to examine the relative effects of these different methods. OBJECTIVES To assess the relative effects (benefits and harms) of different surgical interventions (microfracture, drilling, mosaicplasty, and allograft transplantation) for treating isolated cartilage defects of the knee in adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, CENTRAL, EMBASE, MEDLINE, SPORTDiscus, LILACS, trial registers and conference proceedings up to February 2016. SELECTION CRITERIA Any randomised or quasi-randomised trials that evaluated surgical interventions (microfracture, drilling, mosaicplasty, and allograft transplantation) for treating isolated cartilage defects of the knee in adults. DATA COLLECTION AND ANALYSIS At least two review authors independently selected studies, assessed risk of bias and extracted data. Intervention effects were assessed using risk ratios (RR) for dichotomous data and mean differences (MD) for continuous data, with 95% confidence intervals (CI). Data were pooled using the fixed-effect model, where possible. MAIN RESULTS We included three randomised controlled trials comparing mosaicplasty versus microfracture for isolated cartilage defects in adults. Two trials were single-centre trials and one involved three centres. These small trials reported results for a total of 133 participants, of whom 79 (59%) were male. Mean participant age in the three trials ranged from 24.4 years to 32.3 years. All studies included grade 3 or 4 cartilage lesions (International Cartilage Repair Society (ICRS) classification). The defect area ranged from 1.0 cm² to 6.0 cm²; the mean area in all three trials was 2.8 cm². No trials of allograft transplantation or drilling were identified.All trials were judged as being at high or unclear risk of performance and reporting bias. We judged that the quality of evidence was very low for all outcomes. For individual outcomes, we downgraded the quality of evidence by one or two levels for risk of bias, one level for indirectness where there were data from a single-centre trial only, one or two levels for imprecision where there were wide confidence intervals and an insufficient number of events, and one level for inconsistency reflecting heterogeneity. This means that we are very uncertain about the estimates for all outcomes.There is very low quality evidence from one single-centre trial (57 participants), which included athletes only, that mosaicplasty resulted in higher patient-reported function scores (probably the IKDC 2000 subjective knee evaluation score) compared with microfracture (range 0 to 100; higher score = better function) at one year follow-up (MD 10.29 favouring mosaicplasty, 95% CI 7.87 to 12.71). Very low quality evidence from the same trial showed that this effect persisted in the long term at 10 years follow-up. However, there is very low quality evidence from the two other trials (72 participants) of little difference in patient-reported function, assessed via the Lysholm score (range 0 to 100; higher score = better function), between the two groups at long-term follow-up (MD -1.10 favouring microfracture, 95% CI -4.54 to 2.33). One trial (25 participants) provided very low quality evidence of no significant difference between the two groups in quality of life or pain at long-term follow-up. Pooled results for treatment failure - primarily symptom recurrence - reported at long-term follow-up (means ranging from 6.3 to 1.4 years) in the three trials (129 participants) favoured mosaicplasty (10/64 versus 20/65; RR 0.47, 95% CI 0.24 to 0.90). Based on an illustrative risk of 379 treatment failures per 1000 patients treated with microfracture, there is very low quality evidence that 201 fewer patients (95% CI 38 to 288 fewer) would have treatment failure after mosaicplasty. All three trials reported activity scores but due to clear statistical and clinical heterogeneity, we did not pool the long term Tegner score results. There was very low quality evidence from one study (57 participants) of higher Tegner scores - indicating greater activity - at intermediate-term and long-term follow-up in the mosaicplasty group; however, the between-group difference may not be clinically important. The other two trials provided very low quality evidence of no significant difference between the two groups in activity scores. AUTHORS' CONCLUSIONS We found no evidence from randomised controlled trials on allograft transplantation or drilling. The very low quality evidence from RCTs comparing mosaicplasty with microfracture is insufficient to draw conclusions on the relative effects of these two interventions for treating isolated cartilage defects of the knee in adults. Of note is that treatment failure, with recurrence of symptoms, occurred with both procedures. Further research is needed to define the best surgical option for treating isolated cartilage defects. We suggest the greatest need is for multi-centre RCTs comparing reconstructive procedures (mosaicplasty versus allograft transplantation) for large osteochondral lesions and reparative procedures (microfracture versus drilling) for small chondral lesions.

Abstract
BACKGROUND Rupture of the anterior cruciate ligament (ACL) is a common injury, mainly affecting young, physically active individuals. The injury is characterised by joint instability, leading to decreased activity, which can lead to poor knee-related quality of life. It is also associated with increased risk of secondary osteoarthritis of the knee. It is unclear whether stabilising the knee surgically via ACL reconstruction produces a better overall outcome than non-surgical (conservative) treatment. OBJECTIVES To assess the effects of surgical versus conservative interventions for treating ACL injuries. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (18 January 2016), the Cochrane Central Register of Controlled Trials (2016, Issue 1), MEDLINE (1946 to January Week 1 2016), MEDLINE In-Process & Other Non-Indexed Citations (18 January 2016), EMBASE (1974 to 15 January 2016), trial registers (February 2016) and reference lists. SELECTION CRITERIA We included randomised controlled trials that compared the use of surgical and conservative interventions in participants with an ACL rupture. We included any trial that evaluated surgery for ACL reconstruction using any method of reconstruction, type of reconstruction technique, graft fixation or type of graft. DATA COLLECTION AND ANALYSIS Three review authors independently screened all titles and abstracts for potentially eligible studies, for which we then obtained full-text reports. Two authors then independently confirmed eligibility, extracted data and assessed the risk of bias using the Cochrane 'Risk of bias' tool. We used the GRADE approach to assess the overall quality of the evidence. MAIN RESULTS We identified one study in which 141 young, active adults with acute ACL injury were randomised to either ACL reconstruction followed by structured rehabilitation (results reported for 62 participants) or conservative treatment comprising structured rehabilitation alone (results reported for 59 participants). Built into the study design was a formal option for subsequent (delayed) ACL reconstruction in the conservative treatment group, if the participant requested surgery and met pre-specified criteria.This study was deemed at low risk of selection and reporting biases, at high risk of performance and detection biases because of the lack of blinding and at unclear risk of attrition bias because of an imbalance in the post-randomisation exclusions. According to GRADE methodology, the overall quality of the evidence was low across different outcomes.This study identified no difference in subjective knee score (measured using the average score on four of the five sub-scales of the KOOS score (range from 0 (extreme symptoms) to 100 (no symptoms)) between ACL reconstruction and conservative treatment at two years (difference in KOOS-4 change from baseline scores: MD -0.20, 95% confidence interval (CI) -6.78 to 6.38; N = 121 participants; low-quality evidence), or at five years (difference in KOOS-4 final scores: MD -2.0, 95% CI -8.27 to 4.27; N = 120 participants; low-quality evidence). The total number of participants incurring one or more complications in each group was not reported; serious events reported in the surgery group were predominantly surgery-related, while those in conservative treatment group were predominantly knee instability. There were also incomplete data for total participants with treatment failure, including subsequent surgery. In the surgical group at two years, there was low-quality evidence of far fewer ACL-related treatment failures, when defined as either graft rupture or subsequent ACL reconstruction. This result is dominated by the uptake by 39% (23/59) of the participants in the conservative treatment group of ACL reconstruction for knee instability at two years and by 51% (30/59) of the participants at five years. There was low-quality evidence of little difference between the two groups in participants who had undergone meniscal surgery at anytime up to five years. There was low-quality evidence of no clinically important between-group differences in SF-36 physical component scores at two years. There was low-quality evidence of a higher return to the same or greater level of sport activity at two years in the ACL reconstruction group, but the wide 95% CI also included the potential for a higher return in the conservative treatment group. Based on an illustrative return to sport activities of 382 per 1000 conservatively treated patients, this amounts to an extra 84 returns per 1000 ACL-reconstruction patients (95% CI 84 fewer to 348 more). There was very low-quality evidence of a higher incidence of radiographically-detected osteoarthritis in the surgery group (19/58 (35%) versus 10/55 (18%)). AUTHORS' CONCLUSIONS For adults with acute ACL injuries, we found low-quality evidence that there was no difference between surgical management (ACL reconstruction followed by structured rehabilitation) and conservative treatment (structured rehabilitation only) in patient-reported outcomes of knee function at two and five years after injury. However, these findings need to be viewed in the context that many participants with an ACL rupture remained symptomatic following rehabilitation and later opted for ACL reconstruction surgery. Further research, including the two identified ongoing trials, will help to address the limitations in the current evidence, which is from one small trial in a young, active, adult population.

Abstract
BACKGROUND Ankle fractures, which usually occur after a twisting incident, are a diverse collection of injuries with different levels of complexity and severity. They have an incidence of 1 in 1000 a year in children. Treatment generally involves splints and casts for minor fractures and surgical fixation with screws, plates and pins followed by immobilisation for more serious fractures. OBJECTIVES To assess the effects (benefits and harms) of different interventions for treating ankle fractures in children. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (22 September 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (2015, Issue 8), MEDLINE (1946 to September Week 2 2015), MEDLINE In-Process & Other Non-Indexed Citations (21 September 2015), EMBASE (1980 to 2015 Week 38), CINAHL (1937 to 22 September 2015), trial registers (17 February 2015), conference proceedings and reference lists of articles. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials evaluating interventions for treating ankle fractures in children. DATA COLLECTION AND ANALYSIS Two review authors independently screened titles, abstracts and full articles for inclusion, assessed risk of bias and collected data. We undertook no meta-analysis. MAIN RESULTS We included three randomised controlled trials reporting results for 189 children, all of whom had a clinical diagnosis of a "low risk" ankle fracture. These were predominantly classified as undisplaced Salter-Harris type I fractures of the distal fibula. All three trials compared non-surgical management options. The three trials were at high risk of bias, primarily relating to the impracticality of blinding participants and treating clinicians to the allocated interventions.Two trials compared the Aircast Air-Stirrup ankle brace versus a rigid cast, which was a removable fibreglass posterior splint in one trial (trial A) and a below-knee fibreglass walking cast in the other trial (trial B). In trial A, both devices were removed at around two weeks. In trial B, removal of the brace was optional after five days, while the walking cast was removed after three weeks. There was low-quality evidence of clinically important differences in function scores at four weeks in favour of the brace groups of both trials. Function was measured using the Activities Scale for Kids-performance (ASKp; score range 0 to 100, higher scores mean better function) in trial A and using a modified version of the ASKp score (range 0 to 100%, higher percentages mean better function) in trial B. The results for trial A (40 participants) were median 91.9 in the brace group versus 84.2 in the splint group. The results for trial B (104 participants) were 91.3% versus 85.3%; mean difference (MD) 6.00% favouring brace (95% confidence interval (CI) 1.38% to 10.62%). Trial B indicated that 5% amounted to a clinically relevant difference in the modified ASKp score. Neither trial reported on unacceptable anatomy or related outcomes or long-term follow-up. There was very low-quality evidence relating to adverse events, none of which were serious. Trial A found twice as many children with pressure-related complications in the brace group (10 of 20 versus 5 of 20). In contrast, trial B found four times as many children in the cast group had adverse outcomes assessed in terms of an unscheduled visit to a healthcare provider (4 of 54 versus 16 of 50). Both trials linked some of the adverse events in the brace group with the failure to wear a protective sock. There was very low-quality evidence indicating an earlier return to pre-injury activity in the brace groups in both trials. Trial B provided low-quality evidence that children much prefer five days or more wearing an ankle brace than three weeks immobilised in a walking ankle cast. There was moderate-quality evidence of a lack of difference between the two groups in pain at four weeks.The third trial compared the Tubigrip bandage plus crutches and advice versus a plaster of Paris walking cast for two weeks and reported results at four weeks' follow-up for 45 children with an inversion injury of the ankle. The trial found very low-quality evidence of little difference in pain and function between the two groups, measured using a non-validated pain and function score at four weeks. The trial did not report on adverse effects. There was very low-quality evidence of an earlier return to normal activities, averaging six days, in children treated with Tubigrip (mean 14.17 days for Tubigrip versus 20.19 days for cast; MD -6.02 days, 95% CI -8.92 to -3.12 days).Recent evidence from magnetic resonance imaging studies of the main category of injury evaluated in these three trials suggests that most of the injuries in these trials were sprains or bone bruises rather than fractures of the distal fibular growth plate. AUTHORS' CONCLUSIONS There is low-quality evidence of a quicker recovery of self reported function at four weeks in children with clinically diagnosed low-risk ankle fractures who are treated with an ankle brace compared with those treated with a rigid cast, especially a non-removable walking cast. There is otherwise a lack of evidence from randomised controlled trials to inform clinical practice for children with ankle fractures. Research to identify and address priority questions on the treatment of these common fractures is needed.

Abstract
BACKGROUND Fracture of the distal radius is a common clinical problem, particularly in older people with osteoporosis. There is considerable variation in the management, including rehabilitation, of these fractures. This is an update of a Cochrane review first published in 2002 and last updated in 2006. OBJECTIVES To examine the effects of rehabilitation interventions in adults with conservatively or surgically treated distal radial fractures. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL 2014; Issue 12), MEDLINE, EMBASE, CINAHL, AMED, PEDro, OTseeker and other databases, trial registers, conference proceedings and reference lists of articles. We did not apply any language restrictions. The date of the last search was 12 January 2015. SELECTION CRITERIA Randomised controlled trials (RCTs) or quasi-RCTs evaluating rehabilitation as part of the management of fractures of the distal radius sustained by adults. Rehabilitation interventions such as active and passive mobilisation exercises, and training for activities of daily living, could be used on their own or in combination, and be applied in various ways by various clinicians. DATA COLLECTION AND ANALYSIS The review authors independently screened and selected trials, and reviewed eligible trials. We contacted study authors for additional information. We did not pool data. MAIN RESULTS We included 26 trials, involving 1269 mainly female and older patients. With few exceptions, these studies did not include people with serious fracture or treatment-related complications, or older people with comorbidities and poor overall function that would have precluded trial participation or required more intensive treatment. Only four of the 23 comparisons covered by these 26 trials were evaluated by more than one trial. Participants of 15 trials were initially treated conservatively, involving plaster cast immobilisation. Initial treatment was surgery (external fixation or internal fixation) for all participants in five trials. Initial treatment was either surgery or plaster cast alone in six trials. Rehabilitation started during immobilisation in seven trials and after post-immobilisation in the other 19 trials. As well as being small, the majority of the included trials had methodological shortcomings and were at high risk of bias, usually related to lack of blinding, that could affect the validity of their findings. Based on GRADE criteria for assessment quality, we rated the evidence for each of the 23 comparisons as either low or very low quality; both ratings indicate considerable uncertainty in the findings.For interventions started during immobilisation, there was very low quality evidence of improved hand function for hand therapy compared with instructions only at four days after plaster cast removal, with some beneficial effects continuing one month later (one trial, 17 participants). There was very low quality evidence of improved hand function in the short-term, but not in the longer-term (three months), for early occupational therapy (one trial, 40 participants), and of a lack of differences in outcome between supervised and unsupervised exercises (one trial, 96 participants).Four trials separately provided very low quality evidence of clinically marginal benefits of specific interventions applied in addition to standard care (therapist-applied programme of digit mobilisation during external fixation (22 participants); pulsed electromagnetic field (PEMF) during cast immobilisation (60 participants); cyclic pneumatic soft tissue compression using an inflatable cuff placed under the plaster cast (19 participants); and cross-education involving strength training of the non-fractured hand during cast immobilisation with or without surgical repair (39 participants)).For interventions started post-immobilisation, there was very low quality evidence from one study (47 participants) of improved function for a single session of physiotherapy, primarily advice and instructions for a home exercise programme, compared with 'no intervention' after cast removal. There was low quality evidence from four heterogeneous trials (30, 33, 66 and 75 participants) of a lack of clinically important differences in outcome in patients receiving routine physiotherapy or occupational therapy in addition to instructions for home exercises versus instructions for home exercises from a therapist. There was very low quality evidence of better short-term hand function in participants given physiotherapy than in those given either instructions for home exercises by a surgeon (16 participants, one trial) or a progressive home exercise programme (20 participants, one trial). Both trials (46 and 76 participants) comparing physiotherapy or occupational therapy versus a progressive home exercise programme after volar plate fixation provided low quality evidence in favour of a structured programme of home exercises preceded by instructions or coaching. One trial (63 participants) provided very low quality evidence of a short-term, but not persisting, benefit of accelerated compared with usual rehabilitation after volar plate fixation.For trials testing single interventions applied post-immobilisation, there was very low quality evidence of no clinically significant differences in outcome in patients receiving passive mobilisation (69 participants, two trials), ice (83 participants, one trial), PEMF (83 participants, one trial), PEMF plus ice (39 participants, one trial), whirlpool immersion (24 participants, one trial), and dynamic extension splint for patients with wrist contracture (40 participants, one trial), compared with no intervention. This finding applied also to the trial (44 participants) comparing PEMF versus ice, and the trial (29 participants) comparing manual oedema mobilisation versus traditional oedema treatment. There was very low quality evidence from single trials of a short-term benefit of continuous passive motion post-external fixation (seven participants), intermittent pneumatic compression (31 participants) and ultrasound (38 participants). AUTHORS' CONCLUSIONS The available evidence from RCTs is insufficient to establish the relative effectiveness of the various interventions used in the rehabilitation of adults with fractures of the distal radius. Further randomised trials are warranted. However, in order to optimise research effort and engender the large multicentre randomised trials that are required to inform practice, these should be preceded by research that aims to identify priority questions.

Abstract
BACKGROUND Recovery strategies are often used with the intention of preventing or minimising muscle soreness after exercise. Whole-body cryotherapy, which involves a single or repeated exposure(s) to extremely cold dry air (below -100 °C) in a specialised chamber or cabin for two to four minutes per exposure, is currently being advocated as an effective intervention to reduce muscle soreness after exercise. OBJECTIVES To assess the effects (benefits and harms) of whole-body cryotherapy (extreme cold air exposure) for preventing and treating muscle soreness after exercise in adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, the British Nursing Index and the Physiotherapy Evidence Database. We also searched the reference lists of articles, trial registers and conference proceedings, handsearched journals and contacted experts.The searches were run in August 2015. SELECTION CRITERIA We aimed to include randomised and quasi-randomised trials that compared the use of whole-body cryotherapy (WBC) versus a passive or control intervention (rest, no treatment or placebo treatment) or active interventions including cold or contrast water immersion, active recovery and infrared therapy for preventing or treating muscle soreness after exercise in adults. We also aimed to include randomised trials that compared different durations or dosages of WBC. Our prespecified primary outcomes were muscle soreness, subjective recovery (e.g. tiredness, well-being) and adverse effects. DATA COLLECTION AND ANALYSIS Two review authors independently screened search results, selected studies, assessed risk of bias and extracted and cross-checked data. Where appropriate, we pooled results of comparable trials. The random-effects model was used for pooling where there was substantial heterogeneity. We assessed the quality of the evidence using GRADE. MAIN RESULTS Four laboratory-based randomised controlled trials were included. These reported results for 64 physically active predominantly young adults (mean age 23 years). All but four participants were male. Two trials were parallel group trials (44 participants) and two were cross-over trials (20 participants). The trials were heterogeneous, including the type, temperature, duration and frequency of WBC, and the type of preceding exercise. None of the trials reported active surveillance of predefined adverse events. All four trials had design features that carried a high risk of bias, potentially limiting the reliability of their findings. The evidence for all outcomes was classified as 'very low' quality based on the GRADE criteria.Two comparisons were tested: WBC versus control (rest or no WBC), tested in four studies; and WBC versus far-infrared therapy, also tested in one study. No studies compared WBC with other active interventions, such as cold water immersion, or different types and applications of WBC.All four trials compared WBC with rest or no WBC. There was very low quality evidence for lower self-reported muscle soreness (pain at rest) scores after WBC at 1 hour (standardised mean difference (SMD) -0.77, 95% confidence interval (CI) -1.42 to -0.12; 20 participants, 2 cross-over trials); 24 hours (SMD -0.57, 95% CI -1.48 to 0.33) and 48 hours (SMD -0.58, 95% CI -1.37 to 0.21), both with 38 participants, 2 cross-over studies, 1 parallel group study; and 72 hours (SMD -0.65, 95% CI -2.54 to 1.24; 29 participants, 1 cross-over study, 1 parallel group study). Of note is that the 95% CIs also included either no between-group differences or a benefit in favour of the control group. One small cross-over trial (9 participants) found no difference in tiredness but better well-being after WBC at 24 hours post exercise. There was no report of adverse events.One small cross-over trial involving nine well-trained runners provided very low quality evidence of lower levels of muscle soreness after WBC, when compared with infrared therapy, at 1 hour follow-up, but not at 24 or 48 hours. The same trial found no difference in well-being but less tiredness after WBC at 24 hours post exercise. There was no report of adverse events. AUTHORS' CONCLUSIONS There is insufficient evidence to determine whether whole-body cryotherapy (WBC) reduces self-reported muscle soreness, or improves subjective recovery, after exercise compared with passive rest or no WBC in physically active young adult males. There is no evidence on the use of this intervention in females or elite athletes. The lack of evidence on adverse events is important given that the exposure to extreme temperature presents a potential hazard. Further high-quality, well-reported research in this area is required and must provide detailed reporting of adverse events.

Abstract
BACKGROUND Fractures of the tibial plateau, which are intra-articular injuries of the knee joint, are often difficult to treat and have a high complication rate, including early-onset osteoarthritis. Surgical fixation is usually used for more complex tibial plateau fractures. Additionally, bone void fillers are often used to address bone defects caused by the injury. Currently there is no consensus on either the best method of fixation or bone void filler. OBJECTIVES To assess the effects (benefits and harms) of different surgical interventions, and the use of bone void fillers, for treating tibial plateau fractures. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (12 September 2014), the Cochrane Central Register of Controlled Trials (2014 Issue 8), MEDLINE (1946 to September Week 1 2014), EMBASE (1974 to 2014 Week 36), trial registries (4 July 2014), conference proceedings and grey literature (4 July 2014). SELECTION CRITERIA We included randomised and quasi-randomised controlled clinical trials comparing surgical interventions for treating tibial plateau fractures and the different types of filler for filling bone defects. DATA COLLECTION AND ANALYSIS Two review authors independently screened search results, selected studies, extracted data and assessed risk of bias. We calculated risk ratios (RR) for dichotomous outcomes and mean differences (MD) for continuous outcomes, with 95% confidence intervals (CIs). Only very limited pooling, using the fixed-effect model, was possible. Our primary outcomes were quality of life measures, patient-reported outcome measures of lower limb function and serious adverse events. MAIN RESULTS We included six trials in the review, with a total of 429 adult participants, the majority of whom were male (63%). Three trials evaluated different types of fixation and three analysed different types of bone graft substitutes. All six trials were small and at substantial risk of bias. We judged the quality of most of the available evidence to be very low, meaning that we are very uncertain about these results.One trial compared the use of a circular fixator combined with insertion of percutaneous screws (hybrid fixation) versus standard open reduction and internal fixation (ORIF) in people with open or closed Schatzker types V or VI tibial plateau fractures. Results (66 participants) for quality of life scores using the 36-item Short Form Health Survey (SF-36)), Hospital for Special Surgery (HSS) scores and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) function scores tended to favour hybrid fixation, but a benefit of ORIF could not be ruled out. Participants in the hybrid fixation group had a lower risk for an unplanned reoperation (351 per 1000 people compared with 450 in the ORIF group; 95% CI 197 fewer to 144 more) and were more likely to have returned to their pre-injury activity level (303 per 1000 people, compared with 121 in the ORIF group; 95% CI 15 fewer to 748 more). Results of the two groups were comparable for the WOMAC pain subscale and stiffness scores, but mean knee range of motion values were higher in the hybrid group.Another trial compared the use of a minimally invasive plate (LISS system) versus double-plating ORIF in 84 people who had open or closed bicondylar tibial plateau fractures. Nearly twice as many participants (22 versus 12) in the ORIF group had a bone graft. Quality of life, pain, knee range of motion and return to pre-injury activity were not reported. The trial provided no evidence of differences in HSS knee scores, complications or reoperation entailing implant removal or revision fixation. A quasi-randomised trial comparing arthroscopically-assisted percutaneous reduction and internal fixation versus standard ORIF reported results at 14 months in 58 people with closed Schatzker types II or III tibial plateau fracture. Quality of life, pain and return to pre-injury activity were not reported. There was very low quality evidence of higher HSS knee scores and higher knee range of motion values in the arthroscopically assisted group. No reoperations were reported.Three trials compared different types of bone substitute versus autologous bone graft (autograft) for managing bone defects. Quality of life, pain and return to pre-injury activity were not reported. Only one trial (25 participants) reported on lower limb function, finding good or excellent results in both groups for walking, climbing stairs, squatting and jumping at 12 months. The incidences of individual complications were similar between groups in all three trials. One trial found no cases of inflammatory response in the 20 participants receiving bone substitute, and two found no complications associated with the donor site in the autograft group (58 participants). However, all 38 participants in the autologous iliac bone graft group of one trial reported prolonged pain from the harvest site. Two trials reported similar range of motion results in the two groups, whereas the third trial favoured the bone substitute group. AUTHORS' CONCLUSIONS Currently, there is insufficient evidence to ascertain the best method of fixation or the best method of addressing bone defects during surgery. However, the evidence does not contradict approaches aiming to limit soft-tissue dissection and damage or to avoid autograft donor site complications through using bone substitutes. Further well-designed, larger randomised trials are warranted.

Abstract
BACKGROUND Fractures of the distal femur (the part of the thigh bone nearest the knee) are a considerable cause of morbidity. Various different surgical and non-surgical treatments have been used in the management of these injuries but the best treatment remains controversial. OBJECTIVES To assess the effects (benefits and harms) of interventions for treating fractures of the distal femur in adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (9 September 2014); the Cochrane Central Register of Controlled Trials (The Cochrane Library, 2014, Issue 8); MEDLINE (1946 to August week 4 2014); EMBASE (1980 to 2014 week 36); World Health Organization (WHO) International Clinical Trials Registry Platform (January 2015); conference proceedings and reference lists without language restrictions. SELECTION CRITERIA Randomised and quasi-randomised controlled clinical trials comparing interventions for treating fractures of the distal femur in adults. Our primary outcomes were patient-reported outcome measures (PROMs) of knee function and adverse events, including re-operations. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies and performed data extraction and risk of bias assessment. We assessed treatment effects using risk ratios (RR) or mean differences (MD) and, where appropriate, we pooled data using a fixed-effect model. MAIN RESULTS We included seven studies that involved a total of 444 adults with distal femur fractures. Each of the included studies was small and assessed to be at substantial risk of bias, with four studies being quasi-randomised and none of the studies using blinding in outcome assessment. All studies provided an incomplete picture of outcome. Based on GRADE criteria, we assessed the quality of the evidence as very low for all reported outcomes, which means we are very uncertain of the reliability of these results.One study compared surgical (dynamic condylar screw (DCS) fixation) and non-surgical (skeletal traction) treatment in 42 older adults (mean age 79 years) with displaced fractures of the distal femur. This study, which did not report on PROMs, provided very low quality evidence of little between-group differences in adverse events such as death (2/20 surgical versus 1/20 non-surgical), re-operation or repeat procedures (1/20 versus 3/20) and other adverse effects including delayed union. However, while none of the findings were statistically significant, there were more complications such as pressure sores (0/20 versus 4/20) associated with prolonged immobilisation in the non-surgical group, who stayed on average one month longer in hospital.The other six studies compared different surgical interventions. Three studies, including 159 participants, compared retrograde intramedullary nail (RIMN) fixation versus DCS or blade-plate fixation (fixed-angle devices). None of these studies reported PROMS relating to function. None of the results for the reported adverse events showed a difference between the two implants. Thus, although there was very low quality evidence of a higher risk of re-operation in the RIMN group, the 95% confidence interval (CI) also included the possibility of a higher risk of re-operation for the fixed-angle device (9/83 RIMN versus 4/96 fixed-angle device; 3 studies: RR 1.85, 95% CI 0.62 to 5.57). There was no clinically important difference between the two groups found in quality of life assessed using the 36-item Short Form in one study (23 fractures).One study (18 participants) provided very low quality evidence of there being little difference in adverse events between RIMN and non-locking plate fixation. One study (53 participants) provided very low quality evidence of a higher risk of re-operation after locking plate fixation compared with a single fixed-angle device (6/28 locking plate versus 1/25 fixed-angle device; RR 5.36, 95% CI 0.69 to 41.50); however, the 95% CI also included the possibility of a higher risk of re-operation for the fixed-angle device. Neither of these trials reported on PROMs.The largest included study, which reported outcomes in 126 participants at one-year follow-up, compared RIMN versus locking plate fixation; both implants are commonly used in current practice. None of the between-group differences in the reported outcomes were statistically significant; thus the CIs crossed the line of no effect. There was very low quality evidence of better patient-reported musculoskeletal function in the RIMN group based on Short Musculoskeletal Function Assessment (0 to 100: best function) scores (e.g. dysfunction index: MD -5.90 favouring RIMN, 95% CI -15.13 to 3.33) as well as quality of life using the EuroQoL-5D Index (0 to 1: best quality of life) (MD 0.10 favouring RIMN, 95% CI -0.01 to 0.21). The CIs for both results included a clinically important effect favouring RIMN but also a clinically insignificant effect in favour of locking plate fixation. AUTHORS' CONCLUSIONS This review highlights the major limitations of the available evidence concerning current treatment interventions for fractures of the distal femur. The currently available evidence is incomplete and insufficient to inform current clinical practice. Priority should be given to a definitive, pragmatic, multicentre randomised controlled clinical trial comparing contemporary treatments such as locked plates and intramedullary nails. At minimum, these should report validated patient-reported functional and quality-of-life outcomes at one and two years. All trials should be reported in full using the CONSORT guidelines.

Abstract
BACKGROUND In clinically suspected scaphoid fractures, early diagnosis reduces the risk of non-union and minimises loss in productivity resulting from unnecessary cast immobilisation. Since initial radiographs do not exclude the possibility of a fracture, additional imaging is needed. Computed tomography (CT), magnetic resonance imaging (MRI) and bone scintigraphy (BS) are widely used to establish a definitive diagnosis, but there is uncertainty about the most appropriate method. OBJECTIVES The primary aim of this study is to identify the most suitable diagnostic imaging strategy for identifying clinically suspected fractures of the scaphoid bone in patients with normal radiographs. Therefore we looked at the diagnostic performance characteristics of the most used imaging modalities for this purpose: computed tomography, magnetic resonance imaging and bone scintigraphy. SEARCH METHODS In July 2012, we searched the Cochrane Register of Diagnostic Test Accuracy Studies, MEDLINE, EMBASE, the Database of Abstracts of Reviews of Effects, the Cochrane Central Register of Controlled Trials, the NHS Economic Evaluation Database. In September 2012, we searched MEDION, ARIF, Current Controlled Trials, the World Health Organization (WHO) International Clinical Trials Registry Platform, conference proceedings and reference lists of all articles. SELECTION CRITERIA We included all prospective or retrospective studies involving a consecutive series of patients of all ages that evaluated the accuracy of BS, CT or MRI, or any combination of these, for diagnosing suspected scaphoid fractures. We considered the use of one or two index tests or six-week follow-up radiographs as adequate reference standards. DATA COLLECTION AND ANALYSIS Two review authors independently screened titles and abstracts and assessed full-text reports of potentially eligible studies. The same authors extracted data from full-text reports and assessed methodological quality using the QUADAS checklist. For each index test, estimates of sensitivity and specificity from each study were plotted in ROC space; and forest plots were constructed for visual examination of variation in test accuracy. We performed meta-analyses using the HSROC model to produce summary estimates of sensitivity and specificity. MAIN RESULTS We included 11 studies that looked at diagnostic accuracy of one or two index tests: four studies (277 suspected fractures) looked at CT, five studies (221 suspected fractures) looked at MRI and six studies (543 suspected fractures) looked at BS. Four of the studies made direct comparisons: two studies compared CT and MRI, one study compared CT and BS, and one study compared MRI and BS. Overall, the studies were of moderate to good quality, but relevant clinical information during evaluation of CT, MRI or BS was mostly unclear or unavailable.As few studies made direct comparisons between tests with the same participants, our results are based on data from indirect comparisons, which means that these results are more susceptible to bias due to confounding. Nonetheless, the direct comparisons showed similar patterns of differences in sensitivity and specificity as for the pooled indirect comparisons.Summary sensitivity and specificity of CT were 0.72 (95% confidence interval (CI) 0.36 to 0.92) and 0.99 (95% CI 0.71 to 1.00); for MRI, these were 0.88 (95% CI 0.64 to 0.97) and 1.00 (95% CI 0.38 to 1.00); for BS, these were 0.99 (95% CI 0.69 to 1.00) and 0.86 (95% CI 0.73 to 0.94). Indirect comparisons suggest that diagnostic accuracy of BS was significantly higher than CT and MRI; and CT and MRI have comparable diagnostic accuracy. The low prevalence of a true fracture among suspected fractures (median = 20%) means the lower specificity for BS is problematic. For example, in a cohort of 1000 patients, 112 will be over-treated when BS is used for diagnosis. If CT is used, only 8 will receive unnecessary treatment. In terms of missed fractures, BS will miss 2 fractures and CT will miss 56 fractures. AUTHORS' CONCLUSIONS Although quality of the included studies is moderate to good, findings are based on only 11 studies and the confidence intervals for the summary estimates are wide for all three tests. Well-designed direct comparison studies including CT, MRI and BS could give valuable additional information.Bone scintigraphy is statistically the best diagnostic modality to establish a definitive diagnosis in clinically suspected fractures when radiographs appear normal. However, physicians must keep in mind that BS is more invasive than the other modalities, with safety issues due to level of radiation exposure, as well as diagnostic delay of at least 72 hours. The number of overtreated patients is substantially lower with CT and MRI.Prior to performing comparative studies, there is a need to raise the initially detected prevalence of true fractures in order to reduce the effect of the relatively low specificity in daily practice. This can be achieved by improving clinical evaluation and initial radiographical assessment.

Abstract
BACKGROUND Achilles tendinopathy is a common condition, often with significant functional consequences. As a wide range of injection treatments are available, a review of randomised trials evaluating injection therapies to help inform treatment decisions is warranted. OBJECTIVES To assess the effects (benefits and harms) of injection therapies for people with Achilles tendinopathy. SEARCH METHODS We searched the following databases up to 20 April 2015: the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, AMED, CINAHL and SPORTDiscus. We also searched trial registers (29 May 2014) and reference lists of articles to identify additional studies. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials evaluating injection therapies in adults with an investigator-reported diagnosis of Achilles tendinopathy. We accepted comparison arms of placebo (sham) or no injection control, or other active treatment (such as physiotherapy, pharmaceuticals or surgery). Our primary outcomes were function, using measures such as the VISA-A (Victorian Institute of Sport Assessment-Achilles questionnaire), and adverse events. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data from the included studies. We assessed treatment effects using mean differences (MDs) and 95% confidence intervals (CIs) for continuous variables and risk ratios (RRs) and 95% CIs for dichotomous variables. For follow-up data, we defined short-term as up to six weeks, medium-term as up to three months and longer-term as data beyond three months. We performed meta-analysis where appropriate. MAIN RESULTS We included 18 studies (732 participants). Seven trials exclusively studied athletic populations. The mean ages of the participants in the individual trials ranged from 20 years to 50 years. Fifteen trials compared an injection therapy with a placebo injection or no injection control, four trials compared an injection therapy with active treatment, and one compared two different concentrations of the same injection. Thus no trials compared different injection therapies. Two studies had three trial arms and we included them twice in two different categories. Within these categories, we further subdivided injection therapies by mode of action (injury-causing versus direct repair agents).The risk of bias was unclear (due to poor reporting) or high in six trials published between 1987 and 1994. Improved methodology and reporting for the subsequent trials published between 2004 and 2013 meant that these were at less risk of bias.Given the very low quality evidence available from each of four small trials comparing different combinations of injection therapy versus active treatment and the single trial comparing two doses of one injection therapy, only the results of the first comparison (injection therapy versus control) are presented.There is low quality evidence of a lack of significant or clinically important differences in VISA-A scores (0 to 100: best function) between injection therapy and control groups at six weeks (MD 0.79, 95% CI -4.56 to 6.14; 200 participants, five trials), three months (MD -0.94, 95% CI -6.34 to 4.46; 189 participants, five trials) or between six and 12 months (MD 0.14, 95% CI -6.54 to 6.82; 132 participants, three trials). Very low quality evidence from 13 trials showed little difference between the two groups in adverse events (14/243 versus 12/206; RR 0.97, 95% CI 0.50 to 1.89), most of which were minor and short-lasting. The only major adverse event in the injection therapy group was an Achilles tendon rupture, which happened in a trial testing corticosteroid injections. There was very low quality evidence in favour of the injection therapy group in short-term (under three months) pain (219 participants, seven trials) and in the return to sports (335 participants, seven trials). There was very low quality evidence indicating little difference between groups in patient satisfaction with treatment (152 participants, four trials). There was insufficient evidence to conclude on subgroup differences based on mode of action given that only two trials tested injury-causing agents and the clear heterogeneity of the other 13 trials, which tested seven different therapies that act directly on the repair pathway. AUTHORS' CONCLUSIONS There is insufficient evidence from randomised controlled trials to draw conclusions on the use, or to support the routine use, of injection therapies for treating Achilles tendinopathy. This review has highlighted a need for definitive research in the area of injection therapies for Achilles tendinopathy, including in older non-athletic populations. This review has shown that there is a consensus in the literature that placebo-controlled trials are considered the most appropriate trial design.

Abstract
BACKGROUND The incidence of hip fracture is increasing and it is more common with increasing age. Surgery is used for almost all hip fractures. Blood loss occurs as a consequence of both the fracture and the surgery and thus red blood cell transfusion is frequently used. However, red blood cell transfusion is not without risks. Therefore, it is important to identify the evidence for the effective and safe use of red blood cell transfusion in people with hip fracture. OBJECTIVES To assess the effects (benefits and harms) of red blood cell transfusion in people undergoing surgery for hip fracture. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (31 October 2014), the Cochrane Central Register of Controlled Trials (The Cochrane Library, 2014, Issue 10), MEDLINE (January 1946 to 20 November 2014), EMBASE (January 1974 to 20 November 2014), CINAHL (January 1982 to 20 November 2014), British Nursing Index Database (January 1992 to 20 November 2014), the Systematic Review Initiative's Transfusion Evidence Library, PubMed for e-publications, various other databases and ongoing trial registers. SELECTION CRITERIA Randomised controlled trials comparing red blood cell transfusion versus no transfusion or an alternative to transfusion, different transfusion protocols or different transfusion thresholds in people undergoing surgery for hip fracture. DATA COLLECTION AND ANALYSIS Three review authors independently assessed each study's risk of bias and extracted data using a study-specific form. We pooled data where there was homogeneity in the trial comparisons and the timing of outcome measurement. We used GRADE criteria to assess the quality (low, moderate or high) of the evidence for each outcome. MAIN RESULTS We included six trials (2722 participants): all compared two thresholds for red blood cell transfusion: a 'liberal' strategy to maintain a haemoglobin concentration of usually 10 g/dL versus a more 'restrictive' strategy based on symptoms of anaemia or a lower haemoglobin concentration, usually 8 g/dL. The exact nature of the transfusion interventions, types of surgery and participants varied between trials. The mean age of participants ranged from 81 to 87 years and approximately 24% of participants were men. The largest trial enrolled 2016 participants, over 60% of whom had a history of cardiovascular disease. The percentage of participants receiving a red blood cell transfusion ranged from 74% to 100% in the liberal transfusion threshold group and from 11% to 45% in the restrictive transfusion threshold group. There were no results available for the smallest trial (18 participants). All studies were at some risk of bias, in particular performance bias relating to the absence of blinding of personnel. We judged the evidence for all outcomes, except myocardial infarction, was low quality reflecting risk of bias primarily from imbalances in protocol violations in the largest trial and imprecision, often because of insufficient events. Thus, further research is likely to have an important impact on these results.There was no evidence of a difference between a liberal versus restricted threshold transfusion in mortality, at 30 days post hip fracture surgery (risk ratio (RR) 0.92, 95% confidence interval (CI) 0.67 to 1.26; five trials; 2683 participants; low quality evidence) or at 60 days post surgery (RR 1.08, 95% CI 0.80 to 1.44; three trials; 2283 participants; low quality evidence). Assuming an illustrative baseline risk of 50 deaths per 1000 participants in the restricted threshold group at 30 days, these data equate to four fewer (95% CI 17 fewer to 14 more) deaths per 1000 in the liberal threshold group at 30 days.There was no evidence of a difference between a liberal versus restricted threshold transfusion in functional recovery at 60 days, assessed in terms of the inability to walk 10 feet (3 m) without human assistance (RR 1.00, 95% CI 0.87 to 1.15; two trials; 2083 participants; low quality evidence).There was low quality evidence of no difference between the transfusion thresholds in postoperative morbidity for the following complications: thromboembolism (RR 1.15 favouring a restrictive threshold, 95% CI 0.56 to 2.37; four trials; 2416 participants), stroke (RR 2.40 favouring a restrictive threshold, 95% CI 0.85 to 6.79; four trials; 2416 participants), wound infection (RR 1.61 favouring a restrictive threshold, 95% CI 0.77 to 3.35; three trials; 2332 participants), respiratory infection (pneumonia) (RR 1.35 favouring a restrictive threshold, 95% CI 0.95 to 1.92; four trials; 2416 participants) and new diagnosis of congestive heart failure (RR 0.77 favouring a liberal threshold, 95% CI 0.48 to 1.23; three trials; 2332 participants). There was very low quality evidence of a lower risk of myocardial infarction in the liberal compared with the restrictive transfusion threshold group (RR 0.59, 95% CI 0.36 to 0.96; three trials; 2217 participants). Assuming an illustrative baseline risk of myocardial infarction of 24 per 1000 participants in the restricted threshold group, this result was compatible with between one and 15 fewer myocardial infarctions in the liberal threshold group. AUTHORS' CONCLUSIONS We found low quality evidence of no difference in mortality, functional recovery or postoperative morbidity between 'liberal' versus 'restrictive' thresholds for red blood cell transfusion in people undergoing surgery for hip fracture. Although further research may change the estimates of effect, the currently available evidence does not support the use of liberal red blood cell transfusion thresholds based on a 10 g/dL haemoglobin trigger in preference to more restrictive transfusion thresholds based on lower haemoglobin levels or symptoms of anaemia in these people. Future research needs to address the effectiveness of red blood cell transfusions at different time points in the surgical pathway, whether pre-operative, peri-operative or postoperative. In particular, such research would need to consider people who are symptomatic or haemodynamically unstable who were excluded from most of these trials.

Abstract
BACKGROUND The distal tibial metaphysis is located in the lower (distal) part of the tibia (shin bone). Fractures of this part of the tibia are most commonly due to a high energy injury in young men and to osteoporosis in older women. The optimal methods of surgical intervention for a distal tibial metaphyseal fracture remain uncertain. OBJECTIVES To assess the effects (benefits and harms) of surgical interventions for distal tibial metaphyseal fractures in adults. We planned to compare surgical versus non-surgical (conservative) treatment, and different methods of surgical intervention. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (9 December 2014), the Cochrane Central Register of Controlled Trials (2014, Issue 12), MEDLINE (1946 to November Week 3 2014), EMBASE (1980 to 2014 Week 48), the Airiti Library (1967 to 2014 Week 8), China Knowledge Resource Integrated Database (1915 to 2014 Week 8), ClinicalTrials.gov (February 2014) and reference lists of included studies. SELECTION CRITERIA We included randomised and quasi-randomised controlled clinical studies comparing surgical versus non-surgical (conservative) treatment or different surgical interventions for treating distal tibial metaphyseal fractures in adults. Our primary outcomes were patient-reported function and the need for secondary or revision surgery or substantive physiotherapy because of adverse outcomes. DATA COLLECTION AND ANALYSIS Two authors independently selected studies, assessed the risk of bias in each study and extracted data. We resolved disagreement by discussion and, where necessary, in consultation with a third author. Where appropriate we pooled data using the fixed-effect model. MAIN RESULTS We included three randomised trials that evaluated intramedullary nailing versus plating in 213 participants, with useable data from 173 participants of whom 112 were male. The mean age of participants in individual studies ranged from 41 to 44 years. There were no trials comparing surgery with non-surgical treatment. The three included trials were at high risk of performance bias, with one trial also being at high risk of selection, detection and attrition bias. Overall, the quality of available evidence was rated as very low for all outcomes, meaning that we are very unsure about the estimates for all outcomes.The results of two large ongoing trials of nailing versus plating are likely to provide sufficient evidence to address this issue in a future update. AUTHORS' CONCLUSIONS Overall, there is either no or insufficient evidence to draw definitive conclusions on the use of surgery or the best surgical intervention for distal tibial metaphyseal fractures in adults. The available evidence, which is of very low quality, found no clinically important differences in function or pain, and did not confirm a difference in the need for re-operation or risk of complications between nailing and plating.The addition of evidence from two ongoing trials of nailing versus plating should inform this question in future updates. Further randomised trials are warranted on other issues, but should be preceded by research to identify priority questions.

Abstract
BACKGROUND Patellofemoral pain syndrome (PFPS) is a common knee problem, which particularly affects adolescents and young adults. PFPS, which is characterised by retropatellar (behind the kneecap) or peripatellar (around the kneecap) pain, is often referred to as anterior knee pain. The pain mostly occurs when load is put on the knee extensor mechanism when climbing stairs, squatting, running, cycling or sitting with flexed knees. Exercise therapy is often prescribed for this condition. OBJECTIVES To assess the effects (benefits and harms) of exercise therapy aimed at reducing knee pain and improving knee function for people with patellofemoral pain syndrome. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (May 2014), the Cochrane Central Register of Controlled Trials (2014, Issue 4), MEDLINE (1946 to May 2014), EMBASE (1980 to 2014 Week 20), PEDro (to June 2014), CINAHL (1982 to May 2014) and AMED (1985 to May 2014), trial registers (to June 2014) and conference abstracts. SELECTION CRITERIA Randomised and quasi-randomised trials evaluating the effect of exercise therapy on pain, function and recovery in adolescents and adults with patellofemoral pain syndrome. We included comparisons of exercise therapy versus control (e.g. no treatment) or versus another non-surgical therapy; or of different exercises or exercise programmes. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials based on pre-defined inclusion criteria, extracted data and assessed risk of bias. Where appropriate, we pooled data using either fixed-effect or random-effects methods. We selected the following seven outcomes for summarising the available evidence: pain during activity (short-term: ≤ 3 months); usual pain (short-term); pain during activity (long-term: > 3 months); usual pain (long-term); functional ability (short-term); functional ability (long-term); and recovery (long-term). MAIN RESULTS In total, 31 heterogeneous trials including 1690 participants with patellofemoral pain are included in this review. There was considerable between-study variation in patient characteristics (e.g. activity level) and diagnostic criteria for study inclusion (e.g. minimum duration of symptoms) and exercise therapy. Eight trials, six of which were quasi-randomised, were at high risk of selection bias. We assessed most trials as being at high risk of performance bias and detection bias, which resulted from lack of blinding.The included studies, some of which contributed to more than one comparison, provided evidence for the following comparisons: exercise therapy versus control (10 trials); exercise therapy versus other conservative interventions (e.g. taping; eight trials evaluating different interventions); and different exercises or exercise programmes. The latter group comprised: supervised versus home exercises (two trials); closed kinetic chain (KC) versus open KC exercises (four trials); variants of closed KC exercises (two trials making different comparisons); other comparisons of other types of KC or miscellaneous exercises (five trials evaluating different interventions); hip and knee versus knee exercises (seven trials); hip versus knee exercises (two studies); and high- versus low-intensity exercises (one study). There were no trials testing exercise medium (land versus water) or duration of exercises. Where available, the evidence for each of seven main outcomes for all comparisons was of very low quality, generally due to serious flaws in design and small numbers of participants. This means that we are very unsure about the estimates. The evidence for the two largest comparisons is summarised here. Exercise versus control. Pooled data from five studies (375 participants) for pain during activity (short-term) favoured exercise therapy: mean difference (MD) -1.46, 95% confidence interval (CI) -2.39 to -0.54. The CI included the minimal clinically important difference (MCID) of 1.3 (scale 0 to 10), indicating the possibility of a clinically important reduction in pain. The same finding applied for usual pain (short-term; two studies, 41 participants), pain during activity (long-term; two studies, 180 participants) and usual pain (long-term; one study, 94 participants). Pooled data from seven studies (483 participants) for functional ability (short-term) also favoured exercise therapy; standardised mean difference (SMD) 1.10, 95% CI 0.58 to 1.63. Re-expressed in terms of the Anterior Knee Pain Score (AKPS; 0 to 100), this result (estimated MD 12.21 higher, 95% CI 6.44 to 18.09 higher) included the MCID of 10.0, indicating the possibility of a clinically important improvement in function. The same finding applied for functional ability (long-term; three studies, 274 participants). Pooled data (two studies, 166 participants) indicated that, based on the 'recovery' of 250 per 1000 in the control group, 88 more (95% CI 2 fewer to 210 more) participants per 1000 recovered in the long term (12 months) as a result of exercise therapy. Hip plus knee versus knee exercises. Pooled data from three studies (104 participants) for pain during activity (short-term) favoured hip and knee exercise: MD -2.20, 95% CI -3.80 to -0.60; the CI included a clinically important effect. The same applied for usual pain (short-term; two studies, 46 participants). One study (49 participants) found a clinically important reduction in pain during activity (long-term) for hip and knee exercise. Although tending to favour hip and knee exercises, the evidence for functional ability (short-term; four studies, 174 participants; and long-term; two studies, 78 participants) and recovery (one study, 29 participants) did not show that either approach was superior. AUTHORS' CONCLUSIONS This review has found very low quality but consistent evidence that exercise therapy for PFPS may result in clinically important reduction in pain and improvement in functional ability, as well as enhancing long-term recovery. However, there is insufficient evidence to determine the best form of exercise therapy and it is unknown whether this result would apply to all people with PFPS. There is some very low quality evidence that hip plus knee exercises may be more effective in reducing pain than knee exercise alone.Further randomised trials are warranted but in order to optimise research effort and engender the large multicentre randomised trials that are required to inform practice, these should be preceded by research that aims to identify priority questions and attain agreement and, where practical, standardisation regarding diagnostic criteria and measurement of outcome.

Abstract
BACKGROUND Fear of falling is common in older people and associated with serious physical and psychosocial consequences. Exercise (planned, structured, repetitive and purposive physical activity aimed at improving physical fitness) may reduce fear of falling by improving strength, gait, balance and mood, and reducing the occurrence of falls. OBJECTIVES To assess the effects (benefits, harms and costs) of exercise interventions for reducing fear of falling in older people living in the community. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (July 2013), the Central Register of Controlled Trials (CENTRAL 2013, Issue 7), MEDLINE (1946 to July Week 3 2013), EMBASE (1980 to 2013 Week 30), CINAHL (1982 to July 2013), PsycINFO (1967 to August 2013), AMED (1985 to August 2013), the World Health Organization International Clinical Trials Registry Platform (accessed 7 August 2013) and Current Controlled Trials (accessed 7 August 2013). We applied no language restrictions. We handsearched reference lists and consulted experts. SELECTION CRITERIA We included randomised and quasi-randomised trials that recruited community-dwelling people (where the majority were aged 65 and over) and were not restricted to specific medical conditions (e.g. stroke, hip fracture). We included trials that evaluated exercise interventions compared with no intervention or a non-exercise intervention (e.g. social visits), and that measured fear of falling. Exercise interventions were varied; for example, they could be 'prescriptions' or recommendations, group-based or individual, supervised or unsupervised. DATA COLLECTION AND ANALYSIS Pairs of review authors independently assessed studies for inclusion, assessed the risk of bias in the studies and extracted data. We combined effect sizes across studies using the fixed-effect model, with the random-effect model used where significant statistical heterogeneity was present. We estimated risk ratios (RR) for dichotomous outcomes and incidence rate ratios (IRR) for rate outcomes. We estimated mean differences (MD) where studies used the same continuous measures and standardised mean differences (SMD) where different measures or different formats of the same measure were used. Where possible, we performed various, usually prespecified, sensitivity and subgroup analyses. MAIN RESULTS We included 30 studies, which evaluated 3D exercise (Tai Chi and yoga), balance training or strength and resistance training. Two of these were cluster-randomised trials, two were cross-over trials and one was quasi-randomised. The studies included a total of 2878 participants with a mean age ranging from 68 to 85 years. Most studies included more women than men, with four studies recruiting women only. Twelve studies recruited participants at increased risk of falls; three of these recruited participants who also had fear of falling.Poor reporting of the allocation methods in the trials made it difficult to assess the risk of selection bias in most studies. All of the studies were at high risk of performance and detection biases as there was no blinding of participants and outcome assessors and the outcomes were self reported. Twelve studies were at high risk of attrition bias. Using GRADE criteria, we judged the quality of evidence to be 'low' for fear of falling immediately post intervention and 'very low' for fear of falling at short or long-term follow-up and all other outcomes.Exercise interventions were associated with a small to moderate reduction in fear of falling immediately post intervention (SMD 0.37 favouring exercise, 95% confidence interval (CI) 0.18 to 0.56; 24 studies; 1692 participants, low quality evidence). Pooled effect sizes did not differ significantly between the different scales used to measure fear of falling. Although none of the sensitivity analyses changed the direction of effect, the greatest reduction in the size of the effect was on removal of an extreme outlier study with 73 participants (SMD 0.24 favouring exercise, 95% CI 0.12 to 0.36). None of our subgroup analyses provided robust evidence of differences in effect in terms of either the study primary aim (reduction of fear of falling or other aim), the study population (recruitment on the basis of increased falls risk or not), the characteristics of the study exercise intervention or the study control intervention (no treatment or alternative intervention). However, there was some weak evidence of a smaller effect, which included no reduction, of exercise when compared with an alternative control.There was very low quality evidence that exercise interventions may be associated with a small reduction in fear of falling up to six months post intervention (SMD 0.17, 95% CI -0.05 to 0.38; four studies, 356 participants) and more than six months post intervention (SMD 0.20, 95% CI -0.01 to 0.41; three studies, 386 participants).Very low quality evidence suggests exercise interventions in these studies that also reported on fear of falling reduced the risk of falling measured either as participants incurring at least one fall during follow-up or the number of falls during follow-up. Very low quality evidence from four studies indicated that exercise interventions did not appear to reduce symptoms of depression or increase physical activity. The only study reporting the effects of exercise interventions on anxiety found no difference between groups. No studies reported the effects of exercise interventions on activity avoidance or costs. It is important to remember that our included studies do not represent the totality of the evidence of the effect of exercise interventions on falls, depression, anxiety or physical activity as our review only includes studies that reported fear of falling. AUTHORS' CONCLUSIONS Exercise interventions in community-dwelling older people probably reduce fear of falling to a limited extent immediately after the intervention, without increasing the risk or frequency of falls. There is insufficient evidence to determine whether exercise interventions reduce fear of falling beyond the end of the intervention or their effect on other outcomes. Although further evidence from well-designed randomised trials is required, priority should be given to establishing a core set of outcomes that includes fear of falling for all trials examining the effects of exercise interventions in older people living in the community.

Abstract
BACKGROUND Radial head fracture is the most common fracture of the elbow. It usually results from a fall onto an outstretched arm. In 1954, Mason classified these fractures into type 1 (undisplaced), type 2 (simple displaced), and type 3 (comminuted fractures). Aspiration of the elbow joint aims to relieve pressure in the elbow joint and has been used as an initial treatment option for radial head fractures. However, it is an invasive technique with the potential for complications such as infection and injury to nerves and vessels. OBJECTIVES To assess the effects (benefits and harms) of elbow joint aspiration for treating radial head fracture in adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (14 April 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) (14 April 2014), MEDLINE (1946 to April Week 1 2014) and EMBASE (1980 to 2014 Week 15), trial registries, bibliographies and conference proceedings. SELECTION CRITERIA Randomised and quasi-randomised controlled clinical trials comparing aspiration versus no aspiration for treating radial head fractures in adults. DATA COLLECTION AND ANALYSIS Two review authors independently selected articles, assessed risk of bias and extracted data. Disagreements were resolved by discussion. Where appropriate, we pooled results of comparable studies using fixed-effect meta-analysis. MAIN RESULTS We included two trials that involved 126 participants but provided results for only 108 participants. Most participants were adults, typically over 30 years of age. Both trials were at high risk of selection, performance, detection and reporting bias. Reflecting this high risk of bias, we downgraded the quality of evidence two levels for study limitations and a further level for imprecision. Thus we judged the evidence for all outcomes to be 'very low' quality, meaning that we are very uncertain about these estimates.One trial included participants with Mason type 1, 2 or 3 radial head fractures and also a few cases of traumatic elbow hemarthrosis without fracture. The other trial included participants with Mason type 1 and 2 fractures. All participants were managed non-surgically.Neither trial reported functional outcome based on validated patient-reported outcome measures of function or pain using validated measures such as a visual analogue scale. Very low quality evidence (108 participants, two trials) indicates little difference between aspiration and no aspiration in impaired function (unable to carry heavy loads; discomfort when carrying loads) at 12 months (9/51 in aspiration group versus 7/57 in the no aspiration group; risk ratio 1.43 favouring no aspiration, 95% confidence interval (CI) 0.57 to 3.58). Very low quality evidence (two trials) suggests a beneficial effect of aspiration on pain relief immediately after aspiration. Very low quality evidence (one trial, 28 participants) shows less pain after aspiration at three weeks, but it is unclear whether this applies subsequently. Neither trial reported on adverse events (for example, nerve and vascular injuries; deep or superficial infection) from the procedure, but aspiration was reported as being unsuccessful in three participants (7.9%) in one trial. Very low quality evidence indicates little difference in range of motion (based on elbow extension) between the two groups at six weeks (28 participants, one trial) or 12 months (108 participants, two trials). The report of adverse events was incomplete, but one trial (80 participants) reported the absence of three specific complications: myositis ossificans, joint instability or late displacement of the fracture. AUTHORS' CONCLUSIONS There is insufficient evidence to determine the effectiveness of joint aspiration for the initial treatment of radial head fracture in terms of function, pain and range of motion or to determine the safety of the procedure. An examination of current aspiration use, the prospective collection of adverse events and consultation with patients as to their preferences and values would be helpful in guiding decisions about the future design of a multicentre randomised trial aiming to obtain definitive evidence on the use of aspiration for treating radial head fractures.

Abstract
BACKGROUND Hip fracture occurs predominantly in older people, many of whom are frail and undernourished. After hip fracture surgery and rehabilitation, most patients experience a decline in mobility and function. Anabolic steroids, the synthetic derivatives of the male hormone testosterone, have been used in combination with exercise to improve muscle mass and strength in athletes. They may have similar effects in older people who are recovering from hip fracture. OBJECTIVES To examine the effects (primarily in terms of functional outcome and adverse events) of anabolic steroids after surgical treatment of hip fracture in older people. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (10 September 2013), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2013 Issue 8), MEDLINE (1946 to August Week 4 2013), EMBASE (1974 to 2013 Week 36), trial registers, conference proceedings, and reference lists of relevant articles. The search was run in September 2013. SELECTION CRITERIA Randomised controlled trials of anabolic steroids given after hip fracture surgery, in inpatient or outpatient settings, to improve physical functioning in older patients with hip fracture. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials (based on predefined inclusion criteria), extracted data and assessed each study's risk of bias. A third review author moderated disagreements. Only very limited pooling of data was possible. The primary outcomes were function (for example, independence in mobility and activities of daily living) and adverse events, including mortality. MAIN RESULTS We screened 1290 records and found only three trials involving 154 female participants, all of whom were aged above 65 years and had had hip fracture surgery. All studies had methodological shortcomings that placed them at high or unclear risk of bias. Because of this high risk of bias, imprecise results and likelihood of publication bias, we judged the quality of the evidence for all primary outcomes to be very low.These trials tested two comparisons. One trial had three groups and contributed data to both comparisons. None of the trials reported on patient acceptability of the intervention.Two very different trials compared anabolic steroid versus control (no anabolic steroid or placebo). One trial compared anabolic steroid injections (given weekly until discharge from hospital or four weeks, whichever came first) versus placebo injections in 29 "frail elderly females". This found very low quality evidence of little difference between the two groups in the numbers discharged to a higher level of care or dead (one person in the control group died) (8/15 versus 10/14; risk ratio (RR) 0.75, 95% confidence interval (CI) 0.42 to 1.33; P = 0.32), time to independent mobilisation or individual adverse events. The second trial compared anabolic steroid injections (every three weeks for six months) and daily protein supplementation versus daily protein supplementation alone in 40 "lean elderly women" who were followed up for one year after surgery. This trial provided very low quality evidence that anabolic steroid may result in less dependency, assessed in terms of being either dependent in at least two functions or dead (one person in the control group died) at six and 12 months, but the result was also compatible with no difference or an increase in dependency (dependent in at least two levels of function or dead at 12 months: 1/17 versus 5/19; RR 0.22, 95% CI 0.03 to 1.73; P = 0.15). The trial found no evidence of between-group differences in individual adverse events.Two trials compared anabolic steroids combined with another nutritional intervention ('steroid plus') versus control (no 'steroid plus'). One trial compared anabolic steroid injections every three weeks for 12 months in combination with daily supplement of vitamin D and calcium versus calcium only in 63 women who were living independently at home. The other trial compared anabolic steroid injections every three weeks for six months and daily protein supplementation versus control in 40 "lean elderly women". Both trials found some evidence of better function in the steroid plus group. One trial reported greater independence, higher Harris hip scores and gait speeds in the steroid plus group at 12 months. The second trial found fewer participants in the anabolic steroid group were either dependent in at least two functions, including bathing, or dead at six and 12 months (one person in the control group died) (1/17 versus 7/18; RR 0.15, 95% CI 0.02 to 1.10; P = 0.06). Pooled mortality data (2/51 versus 3/51) from the two trials showed no evidence of a difference between the two groups at one year. Similarly, there was no evidence of between-group differences in individual adverse events. Three participants in the steroid group of one trial reported side effects of hoarseness and increased facial hair. The other trial reported better quality of life in the steroid plus group. AUTHORS' CONCLUSIONS The available evidence is insufficient to draw conclusions on the effects, primarily in terms of functional outcome and adverse events, of anabolic steroids, either separately or in combination with nutritional supplements, after surgical treatment of hip fracture in older people. Given that the available data points to the potential for more promising outcomes with a combined anabolic steroid and nutritional supplement intervention, we suggest that future research should focus on evaluating this combination.

Abstract
BACKGROUND Anterior cruciate ligament (ACL) reconstruction is one of the most frequently performed orthopaedic procedures. The most common technical cause of reconstruction failure is graft malpositioning. Computer-assisted surgery (CAS) aims to improve the accuracy of graft placement. Although posterior cruciate ligament (PCL) injury and reconstruction are far less common, PCL reconstruction has comparable difficulties relating to graft placement. This is an update of a Cochrane review first published in 2011. OBJECTIVES To assess the effects of computer-assisted reconstruction surgery versus conventional operating techniques for ACL or PCL injuries in adults. SEARCH METHODS For this update, we searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (from 2010 to July 2013), the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 5, 2013), MEDLINE (from 2010 to July 2013), EMBASE (from 2010 to July 2013), CINAHL (from 2010 to July 2013), article references and prospective trial registers. SELECTION CRITERIA We included randomized controlled trials (RCTs) and quasi-randomized controlled trials that compared CAS for ACL or PCL reconstruction versus conventional operating techniques not involving CAS. DATA COLLECTION AND ANALYSIS Two authors independently screened search results, assessed the risk of bias in the studies and extracted data. Where appropriate, we pooled data using risk ratios (RR) or mean differences (MD), both with 95% confidence intervals (CI). MAIN RESULTS The updated search resulted in the inclusion of one new study. This review now includes five RCTs with 366 participants. There were more female than male participants (70% were female); their ages ranged from 14 to 53 years. All trials involved ACL reconstructions performed by experienced surgeons.Assessing the studies' risk of bias was hampered by poor reporting of trial methods, and consequently several studies were judged to be 'unclear' for several types of bias. One trial presenting primary outcome data was at high risk of detection bias from lack of clinician blinding and attrition bias from an unaccounted loss to follow-up at two years.We found moderate quality evidence (three trials, 193 participants) of no clinically relevant difference between CAS and conventional surgery in International Knee Documentation Committee (IKDC) subjective scores (self-reported measure of knee function; scale of 0 to 100 where 100 was best function). Pooled data from two of these trials (120 participants) showed a small, but clinically irrelevant difference favouring CAS (MD 2.05, 95% CI -2.16 to 6.25). A third trial (73 participants) also found minimal difference in IKDC subjective scores (reported MD 0.2).We found low quality evidence (two trials, 120 participants) showing no difference between the two groups in Lysholm scores, also measured on a scale 0 to 100 where 100 is best function (MD 0.25, 95% CI -3.75 to 4.25). We found very low quality evidence (one trial, 40 participants) showing no difference between the two groups in Tegner scores. We found low quality evidence (three trials, 173 participants) showing the majority of participants in both groups were assessed as having normal or nearly normal knee function (86/87 with CAS versus 84/86 with no CAS; RR 1.01, 95% CI 0.96 to 1.06).Similarly, no differences were found for our secondary outcome measures of knee stability, loss in range of motion and tunnel placement. None of the trials reported on re-operation.No adverse post-surgical events were reported in two trials (133 participants); this outcome was not reported by the other three trials.CAS use was associated with longer operating times compared with conventional operating techniques: the mean difference in operating times reported in the studies ranged between 9 and 27 minutes. AUTHORS' CONCLUSIONS From the available evidence, we are unable to demonstrate or refute a favourable effect of CAS for cruciate ligament reconstructions of the knee compared with conventional reconstructions. However, the currently available evidence does not indicate that CAS in knee ligament reconstruction improves outcome. There is a need for improved reporting of future studies of this technology.

Abstract
BACKGROUND Fractures of the femoral shaft in children are relatively uncommon but serious injuries that disrupt the lives of children and their carers and can result in significant long-term disability. Treatment involves either surgical fixation, such as intramedullary nailing or external fixation, or conservative treatment involving prolonged immobilisation, often in hospital. OBJECTIVES To assess the effects (benefits and harms) of interventions for treating femoral shaft fractures in children and adolescents. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (accessed 16 August 2013), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2013 Issue 7), MEDLINE (1946 to August Week 1 2013), EMBASE (1980 to 2012 week 9), CINAHL (16 August 2013), clinical trials registries, conference proceedings and reference lists; and contacted trial authors and experts in the field. SELECTION CRITERIA Randomised and quasi-randomised controlled trials comparing conservative and surgical interventions for diaphyseal fractures of the femur in children under 18 years of age. Our primary outcomes were functional outcome measures, unacceptable malunion, and serious adverse events. DATA COLLECTION AND ANALYSIS Two authors independently screened and selected trials, assessed risk of bias and extracted data. We assessed the overall quality of the evidence for each outcome for each comparison using the GRADE approach. We pooled data using a fixed-effect model. MAIN RESULTS We included 10 trials (six randomised and four quasi-randomised) involving a total of 527 children (531 fractures). All trials were at some risk of bias, including performance bias as care provider blinding was not practical, but to a differing extent. Just one trial was at low risk of selection bias. Reflecting both the risk of bias and the imprecision of findings, we judged the quality of evidence to be 'low' for most outcomes, meaning that we are unsure about the estimates of effect. Most trials failed to report on self-assessed function or when children resumed their usual activities. The trials evaluated 10 different comparisons, belonging to three main categories. Surgical versus conservative treatment Four trials presenting data for 264 children aged 4 to 12 years made this comparison. Low quality evidence (one trial, 101 children) showed children had very similar function assessed using the RAND health status score at two years after surgery (external fixation) compared with conservative treatment (spica cast): mean 69 versus 68. The other three trials did not report on function. There was moderate quality evidence (four trials, 264 children, aged 4 to 12 years, followed up 3 to 24 months) that surgery reduced the risk of malunion (risk ratio (RR) 0.29, 95% confidence interval (CI) 0.15 to 0.59, 4 trials). Assuming an illustrative baseline risk of 115 malunions per 1000 in children treated conservatively, these data equate to 81 fewer (95% CI 47 to 97 fewer) malunions per 1000 in surgically-treated children. Conversely, low quality evidence indicated that there were more serious adverse events such as infections after surgery (RR 2.39, 95% CI 1.10 to 5.17, 4 trials). Assuming an illustrative baseline risk of 40 serious adverse events per 1000 for conservative treatment, these data equate to 56 more (95% CI 4 to 167 more) serious adverse events per 1000 children treated surgically. There was low quality evidence (one trial, 101 children) of similar satisfaction levels in children and parents with surgery involving external fixation and plaster cast only. However, there was low quality evidence (one trial, 46 children) that more parents were satisfied with intramedullary nailing than with traction followed by a cast, and that surgery reduced the time taken off from school. Comparisons of different methods of conservative treatmentThe three trials in this category made three different comparisons. We are very unsure if unacceptable malunion rates differ between immediate hip spica versus skeletal traction followed by spica in children aged 3 to 10 years followed up for six to eight weeks (RR 4.0, 95% CI 0.5 to 32.9; one trial, 42 children; very low quality evidence). Malunion rates at 5 to 10 years may not differ between traction followed by functional orthosis versus traction followed by spica cast in children aged 5 to 13 years (RR 0.98, 95% CI 0.46 to 2.12; one trial, 43 children; low quality evidence). We are very unsure (very low quality evidence) if either function or serious adverse events (zero events reported) differ between single-leg versus double-leg spica casts (one trial, 52 young children aged two to seven years). Low quality evidence on the same comparison indicates that single-leg casts are less awkward to manage by parents, more comfortable for the child and may require less time off work by the caregiver. Comparisons of different methods of surgical treatmentThe three trials in this category made three different comparisons. Very low quality evidence means that we are very unsure if the rates of malunion, serious adverse events, time to return to school or parental satisfaction actually differ in children whose fractures were fixed using elastic stable intramedullary nailing or external fixation (one trial, 19 children). The same applies to the rates of serious adverse events and time to resume full weight-bearing in children treated with dynamic versus static external fixation (one trial, 52 children). Very low quality evidence (one trial, 47 children) means that we do not know if malunion, serious adverse events and time to resume weight-bearing actually differ between intramedullary nailing versus submuscular plating. However, there could be more difficulties in plate removal subsequently. AUTHORS' CONCLUSIONS There is insufficient evidence to determine if long-term function differs between surgical and conservative treatment. Surgery results in lower rates of malunion in children aged 4 to 12 years, but may increase the risk of serious adverse events. Elastic stable intramedullary nailing may reduce recovery time.There is insufficient evidence from comparisons of different methods of conservative treatment or of different methods of surgical treatment to draw conclusions on the relative effects of the treatments compared in the included trials.

Abstract
BACKGROUND The morbidity and socioeconomic costs of fractures are considerable. The length of time to healing is an important factor in determining a person's recovery after a fracture. Ultrasound may have a therapeutic role in reducing the time to union after fracture. This is an update of a review previously published in February 2012. OBJECTIVES To assess the effects of low-intensity ultrasound (LIPUS), high-intensity focused ultrasound (HIFUS) and extracorporeal shockwave therapies (ECSW) as part of the treatment of acute fractures in adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (2 June 2014), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2014, Issue 5), MEDLINE (1946 to May Week 3 2014), EMBASE (1980 to 2014 Week 22), trial registers and reference lists of articles. SELECTION CRITERIA Randomised and quasi-randomised controlled trials evaluating ultrasound treatment in the management of acute fractures in adults. Studies had to include participants over 18 years of age with acute fractures, reporting outcomes such as function; time to union; non-union; secondary procedures such as for fixation or delayed union or non-union; adverse effects; pain; costs; and patient adherence. DATA COLLECTION AND ANALYSIS Two authors independently extracted data from the included studies. Treatment effects were assessed using mean differences, standardised mean differences or risk ratios using a fixed-effect model, except where there was substantial heterogeneity, when data were pooled using a random-effects model. Results from 'worst case' analyses, which gave more conservative estimates of treatment effects for time to fracture union, are reported in preference to those from 'as reported' analyses. MAIN RESULTS We included 12 studies, involving 622 participants with 648 fractures. Eight studies were randomised placebo-controlled trials, two were randomised controlled trials without placebo controls, one was a quasi-randomised placebo-controlled trial and one was a quasi-randomised controlled trial without placebo control. Eleven trials tested LIPUS and one trial tested ECSW. Four trials included participants with conservatively treated upper limb complete fractures and six trials included participants with lower limb complete fractures; these were surgically fixed in four trials. The remaining two trials reported results for conservatively treated tibial stress fractures.'Risk of bias' assessment of the included studies was hampered by the poor reporting of methods, frequently resulting in the risk of bias of individual domains being judged as 'unclear'. Both quasi-randomised studies were at high risk of bias, including selection and attrition bias. Three studies were at low risk of selection bias relating to allocation concealment the majority of studies were at low risk of performance bias as they employed a form of intervention blinding.Only limited data were available from three of only four studies reporting on functional outcome. One study of complete fractures found little evidence of a difference between the two groups in the time to return to work (mean difference (MD) 1.95 days favouring control, 95% confidence interval (CI) -2.18 to 6.08; 101 participants). Pooled data from two studies found LIPUS did not significantly affect the time to return to training or duty in soldiers or midshipmen with stress fractures (MD -8.55 days, 95% CI -22.71 to 5.61; 93 participants).We adopted a conservative strategy for data analysis that was more likely to underestimate than to overestimate a benefit of the intervention. After pooling results from eight studies (446 fractures), the data showed no statistically significant reduction in time to union of complete fractures treated with LIPUS (standardised mean difference (SMD) -0.47, 95% CI -1.14 to 0.20). This result could include a clinically important benefit or harm, and should be seen in the context of the highly significant statistical heterogeneity (I² = 90%). This heterogeneity was not explained by the a priori subgroup analyses (upper limb versus lower limb fracture, smoking status). An additional subgroup analysis comparing conservatively and operatively treated fractures raised the possibility that LIPUS may be effective in reducing healing time in conservatively managed fractures, but the test for subgroup differences did not confirm a significant difference between the subgroups.Pooled results from five of the eight trials (333 fractures) reporting proportion of delayed union or non-union showed no significant difference between LIPUS and control (10/168 versus 13/165; RR 0.75; 95% CI 0.24 to 2.28). Adverse effects directly associated with LIPUS and associated devices were found to be few and minor, and compliance with treatment was generally good. One study reporting on pain scores found no difference between groups at eight weeks (101 participants).One quasi-randomised study found no significant difference in non-union at 12 months between internal fixation supplemented with ECSW and internal fixation alone (3/27 versus 6/30; RR 0.56, 95% CI 0.15 to 2.01). There was a clinically small but statistically significant difference in the visual analogue scores for pain in favour of ECSW at three month follow-up (MD -0.80, 95% CI -1.23 to -0.37). The only reported complication was infection, with no significant difference between the two groups. AUTHORS' CONCLUSIONS While a potential benefit of ultrasound for the treatment of acute fractures in adults cannot be ruled out, the currently available evidence from a set of clinically heterogeneous trials is insufficient to support the routine use of this intervention in clinical practice. Future trials should record functional outcomes and follow-up all trial participants.

Abstract
BACKGROUND An acute ankle sprain is a sudden-onset injury of one or more of the ankle ligaments. It is one of the most common musculoskeletal injuries in the general population as well as in athletes. In some countries, such as China and Korea, acupuncture is frequently used in the treatment of ankle sprains, either as a single treatment or a secondary intervention accompanied by standard medical treatment. OBJECTIVES To assess the effects (benefits and harms) of acupuncture for the treatment of ankle sprains in adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (May 2013), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2013, Issue 4), MEDLINE (1948 to May week 2 2013), EMBASE (1980 to May week 2 2013), China National Knowledge Infrastructure databases (1994 to August week 4 2013), the Cumulative Index to Nursing and Allied Health Literature (1937 to May 2013), the Allied and Complementary Medicine Database (1985 to May 2013), Science Links Japan (1996 to August week 4 2013), several Korean medical databases (August week 4 2013), the World Health Organization International Clinical Trials Registry Platform (August week 4 2013), the bibliographic references of included trials and conference proceedings. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials involving adults with acute ankle sprains. We included all types of acupuncture practices, such as needle acupuncture, electroacupuncture, laser acupuncture, pharmacoacupuncture, non-penetrating acupuncture point stimulation (e.g. acupressure and magnets) and moxibustion. Acupuncture could be compared with control (no treatment or placebo) or another standard non-surgical intervention. DATA COLLECTION AND ANALYSIS Two review authors independently screened the search results, assessed trial eligibility, assessed risk of bias and extracted data from the included trials. We calculated risk ratios (RRs) for dichotomous outcomes and mean differences for continuous outcomes. We conducted meta-analyses using the fixed-effect method or, where appropriate, the random-effects method, and used 95% confidence intervals (CI) throughout. MAIN RESULTS We included a total of 20 heterogeneous studies (2012 participants with acute ankle sprains); three of which included more than one comparison. Seventeen trials were conducted in China. All of the studies had a high risk of bias due to lack of blinding. The results may also have been affected by selection bias, particularly as five studies were quasi-randomised controlled trials and 12 studies gave no information on their method of randomisation. Of our three prespecified primary outcomes, only cure rate was reported by the majority of studies. No study reported on patient-reported assessment of function and only one reported on adverse events (in which three participants receiving a control intervention experienced skin problems from over-the-counter Chinese herbal patches). The other 19 studies did not record or report on adverse events. We assessed the quality of evidence for cure rates as very low for all comparisons, which means we are very uncertain about the reliability of any of the estimates.The single study comparing acupuncture treatment with no treatment found acupuncture to be more effective with regard to cure rate at five days (31/31 versus 1/30; RR 20.34, 95% CI 4.27 to 96.68). Acupuncture plus another standard treatment versus that standard treatment alone was tested in eight studies; with cure rate data available for seven. Most of these studies reported higher cure rates in the acupuncture plus another standard treatment group than in the standard treatment alone group. However, while the results of an exploratory meta-analysis of cure rate data from eight trials testing acupuncture versus no acupuncture tended to favour acupuncture, the results were very inconsistent across the studies and the estimated effect was very imprecise (383/396 versus 272/355; RR 1.32, 95% CI 0.95 to 1.84; P value = 0.1; I(2) = 98%).Fourteen studies compared acupuncture with a variety of other non-surgical treatments, such as Chinese drug patches, hot and cold water, ice packs, oral Chinese herbal medicine and elastic bandage. Some studies found in favour of acupuncture, some in favour of the other treatment and some found a lack of evidence for a difference between the two interventions under test. The results of an exploratory meta-analysis of cure rate data from 11 trials testing acupuncture versus another non-surgical intervention tended to slightly favour acupuncture, but these were not statistically significant and the data were very heterogeneous (404/509 versus 416/497; RR 1.07, 95% CI 0.94 to 1.22; P value = 0.30; I(2) = 92%). AUTHORS' CONCLUSIONS The currently available evidence from a very heterogeneous group of randomised and quasi-randomised controlled trials evaluating the effects of acupuncture for the treatment of acute ankle sprains does not provide reliable support for either the effectiveness or safety of acupuncture treatments, alone or in combination with other non-surgical interventions; or in comparison with other non-surgical interventions. Future rigorous randomised clinical trials with larger sample sizes will be necessary to establish robust clinical evidence concerning the effectiveness and safety of acupuncture treatment for acute ankle sprains.

Abstract
BACKGROUND Fingertip entrapment injuries, which involve lacerations to the pulp and nail and often a fracture of the underlying bone, commonly occur in children, usually as the result of a crushing injury. Treatment is either conservative (wound cleaning and fingertip dressing)or surgical (repair of lacerations, reduction and stabilisation of fractures); however, no consensus currently exists regarding the most appropriate treatment modality. OBJECTIVES To assess the effects (benefits and harms) of surgical and conservative interventions for fingertip entrapment injuries in children. We aimed to compare: different methods of conservative treatment; surgical versus conservative treatment; different methods of surgical treatment; and different methods of management after initial conservative or surgical treatment. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials (The Cochrane Library), MEDLINE, EMBASE, the World Health Organization Clinical Trials Registry Platform and reference lists of articles up to 30 April 2013. We did not apply any restrictions based on language or publication status. SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs comparing interventions for treating fingertip entrapment injuries in children.The primary outcomes were fingertip function, nail growth, nail deformity and adverse events such as infection. DATA COLLECTION AND ANALYSIS Two authors independently screened studies for inclusion, assessed the risk of bias in each included trial and extracted data.We resolved disagreements through discussion. MAIN RESULTS We included two RCTs examining a total of 191 young children, 180 of whom were included in the analyses. The two trials tested different comparisons. Both trials were at high risk of bias, particularly from lack of blinding of participants and personnel, and of outcome assessment. The trials did not record fingertip function, nail growth or nail deformity. The quality of the evidence for the reported outcomes was judged to be 'low' using the GRADE approach (i.e. further research is very likely to have an important impact on our confidence in the estimate of the effect and is likely to change the estimate).One trial compared a seven-day course of antibiotics with no antibiotics after formal surgical repair of fingertip entrapment injuries.One child in each group had an infection at day seven (1/66 antibiotic group versus 1/69 no antibiotic group; RR 1.05, 95% CI 0.07 to 16.37). Both participants with infections had a more severe injury (partial fingertip amputation).The other trial compared two different dressings (silicone net and paraffin gauze) for use after either surgical or initial conservative management of fingertip entrapment injuries. It reported that two of 20 children in the silicone group versus one of 25 in the paraffin group had complications of wound infection (RR 2.50, 95% CI 0.24 to 25.63) and that one of 20 children in the silicone group versus two of 25 in the paraffin group had skin necrosis (RR 0.63, 95% CI 0.06 to 6.41). All complications healed with conservative treatment. The results for mean healing times and mean number of dressing changes were similar between groups but benefits of either silicone or paraffin dressings could not be excluded (silicone mean 4.1 weeks versus paraffin mean 4.0 weeks;MD 0.10 weeks, 95% CI-0.61 to 0.81); (silicone mean 4.3 dressing changes versus paraffin mean 4.2 dressing changes; MD 0.10, 95% CI -0.57 to 0.77). The trial found that a silicone dressing was less likely to adhere to the wound or cause distress for the child at the one-week dressing change. AUTHORS' CONCLUSIONS There is a lack of evidence from RCTs to inform all key treatment decisions for the management of fingertip entrapment injuries in children.Given that the quality of evidence is low from one trial, we do not have conclusive evidence that prophylactic use of antibiotics after surgical repair fails to reduce risk of infection. The two children who experienced infection had more severe wounds.Similarly, the low quality evidence from one trial has not enabled us to draw firm conclusions regarding the effect on healing time or complications (infection, skin necrosis) at four-week follow-up between a silicone net dressing and a paraffin gauze dressing when applied post-surgery or after simple wound irrigation; however, the silicone net dressing may be easier to remove in the first week.Further RCTs are required in this area, preferably comparing surgical with conservative methods of managing fingertip entrapment injuries. Outcome assessment should include fingertip function, nail growth and nail deformity for a minimum of three months posttreatment.

Abstract
BACKGROUND Platelet-rich therapies are being used increasingly in the treatment of musculoskeletal soft tissue injuries such as ligament, muscle and tendon tears and tendinopathies. These therapies can be used as the principal treatment or as an augmentation procedure (application after surgical repair or reconstruction). Platelet-rich therapies are produced by centrifuging a quantity of the patient's own blood and extracting the active, platelet-rich, fraction. The platelet-rich fraction is applied to the injured tissue; for example, by injection. Platelets have the ability to produce several growth factors, so these therapies should enhance tissue healing. There is a need to assess whether this translates into clinical benefit. OBJECTIVES To assess the effects (benefits and harms) of platelet-rich therapies for treating musculoskeletal soft tissue injuries. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (25 March 2013), the Cochrane Central Register of Controlled Trials (CENTRAL 2013 Issue 2), MEDLINE (1946 to March 2013), EMBASE (1980 to 2013 Week 12) and LILACS (1982 to March 2012). We also searched trial registers (to Week 2 2013) and conference abstracts (2005 to March 2012). No language or publication restrictions were applied. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials that compared platelet-rich therapy with either placebo, autologous whole blood, dry needling or no platelet-rich therapy for people with acute or chronic musculoskeletal soft tissue injuries. Primary outcomes were functional status, pain and adverse effects. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed each study's risk of bias. Disagreement was resolved by discussion or by arbitration by a third author. We contacted trial authors for clarification of methods or missing data. Treatment effects were assessed using risk ratios for dichotomous data and mean differences (MD) or standardised mean differences (SMD) for continuous data, together with 95% confidence intervals. Where appropriate, data were pooled using the fixed-effect model for RR and MD, and the random-effects model for SMD. The quality of the evidence for each outcome was assessed using GRADE criteria. MAIN RESULTS We included data from 19 small single centre trials (17 randomised and two quasi-randomised; 1088 participants) that compared platelet-rich therapy with placebo, autologous whole blood, dry needling or no platelet-rich therapy. These trials covered eight clinical conditions: rotator cuff tears (arthroscopic repair) (six trials); shoulder impingement syndrome surgery (one trial); elbow epicondylitis (three trials); anterior cruciate ligament (ACL) reconstruction (four trials), ACL reconstruction (donor graft site application) (two trials), patellar tendinopathy (one trial), Achilles tendinopathy (one trial) and acute Achilles rupture surgical repair (one trial). We also grouped trials into 'tendinopathies' where platelet-rich therapy (PRT) injections were the main treatment (five trials), and surgical augmentation procedures where PRT was applied during surgery (14 trials). Trial participants were mainly male, except in trials including rotator cuff tears, and elbow and Achilles tendinopathies.Three trials were judged as being at low risk of bias; the other 16 were at high or unclear risk of bias relating to selection, detection, attrition or selective reporting, or combinations of these. The methods of preparing platelet-rich plasma (PRP) varied and lacked standardisation and quantification of the PRP applied to the patient.We were able to pool data for our primary outcomes (function, pain, adverse events) for a maximum of 11 trials and 45% of participants. The evidence for all primary outcomes was judged as being of very low quality.Data assessing function in the short term (up to three months) were pooled from four trials that assessed PRT in three clinical conditions and used four different measures. These showed no significant difference between PRT and control (SMD 0.26; 95% confidence interval (CI) -0.19 to 0.71; P value 0.26; I² = 51%; 162 participants; positive values favour PRT). Medium-term function data (at six months) were pooled from five trials that assessed PRT in five clinical conditions and used five different measures. These also showed no difference between groups (SMD -0.09, 95% CI -0.56 to 0.39; P value 0.72; I² = 50%; 151 participants). Long-term function data (at one year) were pooled from 10 trials that assessed PRT in five clinical conditions and used six different measures. These also showed no difference between groups (SMD 0.25, 95% CI -0.07 to 0.57; P value 0.12; I² = 66%; 484 participants). Although the 95% confidence intervals indicate the possibility of a poorer outcome in the PRT group up to a moderate difference in favour of PRT at short- and long-term follow-up, these do not translate into clinically relevant differences.Data pooled from four trials that assessed PRT in three clinical conditions showed a small reduction in short-term pain in favour of PRT on a 10-point scale (MD -0.95, 95% CI -1.41 to -0.48; I² = 0%; 175 participants). The clinical significance of this result is marginal.Four trials reported adverse events; another seven trials reported an absence of adverse events. There was no difference between treatment groups in the numbers of participants with adverse effects (7/241 versus 5/245; RR 1.31, 95% CI 0.48 to 3.59; I² = 0%; 486 participants).In terms of individual conditions, we pooled heterogeneous data for long-term function from six trials of PRT application during rotator cuff tear surgery. This showed no statistically or clinically significant differences between the two groups (324 participants).The available evidence is insufficient to indicate whether the effects of PRT will differ importantly in individual clinical conditions. AUTHORS' CONCLUSIONS Overall, and for the individual clinical conditions, there is currently insufficient evidence to support the use of PRT for treating musculoskeletal soft tissue injuries. Researchers contemplating RCTs should consider the coverage of currently ongoing trials when assessing the need for future RCTs on specific conditions. There is need for standardisation of PRP preparation methods.

Abstract
BACKGROUND Older people living in nursing care facilities or older adults living at home are at high risk of falling and a hip fracture may occur after a fall. Hip protectors have been advocated as a means to reduce the risk of hip fracture. Hip protectors are plastic shields (hard) or foam pads (soft), usually fitted in pockets in specially designed underwear.This is an update of a Cochrane review first published in 1999, and updated several times, most recently in 2010. OBJECTIVES To determine if the provision of external hip protectors (sometimes referred to as hip pads or hip protector pads) reduces the risk of fracturing the hip in older people. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (December 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 12), MEDLINE (1950 to week 3 November 2012), MEDLINE In-Process (18 December 2012), EMBASE (1988 to 2012 Week 50), CINAHL (1982 to December 2012), BioMed Central (January 2010), trial registers and reference lists of relevant articles. SELECTION CRITERIA All randomised or quasi-randomised controlled trials comparing an intervention group provided with hip protectors with a control group not provided with hip protectors. DATA COLLECTION AND ANALYSIS Two review authors independently assessed risk of bias and extracted data. We sought additional information from trialists. Data were pooled using fixed-effect or random-effects models as appropriate. MAIN RESULTS This review includes 19 studies, nine of which were cluster randomised. These included approximately 17,000 people (mean age range 78 to 86 years). Most studies were overall at low risk of bias for fracture outcomes. Trials tested hard or soft hip protectors enclosed in special underwear in 18 studies.Pooling of data from 14 studies (11,808 participants) conducted in nursing or residential care settings found moderate quality evidence for a small reduction in hip fracture risk (risk ratio (RR) 0.82, 95% confidence interval (CI) 0.67 to 1.00); the absolute effect is 11 fewer people (95% CI, from 20 fewer to 0) per 1000 having a hip fracture when provided with hip protectors.There is moderate quality evidence when pooling data from five trials in the community (5614 participants) that shows little or no effect in hip fracture risk (RR 1.15, 95% CI 0.84 to 1.58); the absolute effect is two more people (95% CI 2 fewer to 6 more) per 1000 people having a hip fracture when provided with hip protectors.There is probably little to no effect on falls (rate ratio 1.02, 95% CI 0.9 to 1.16) or fractures other than of the hip or pelvis (rate ratio 0.87, 95% CI 0.71 to 1.07). However, the risk ratio for pelvic fractures is RR 1.27 (95% CI 0.78 to 2.08); this is an absolute effect of one more person (95% CI 1 fewer to 5 more) per 1000 having a pelvic fracture when provided with hip protectors.The incidence of adverse events while wearing hip protectors, including skin irritation, ranged from 0% to 5%. Adherence, particularly in the long term, was poor. AUTHORS' CONCLUSIONS Hip protectors probably reduce the risk of hip fractures if made available to older people in nursing care or residential care settings, without increasing the frequency of falls. However, hip protectors may slightly increase the small risk of pelvic fractures. Poor acceptance and adherence by older people offered hip protectors is a barrier to their use. Better understanding is needed of the personal and design factors that may influence acceptance and adherence.

Abstract
BACKGROUND Shoulder pain is a very common symptom. Disorders of the rotator cuff tendons due to wear or tear are among the most common causes of shoulder pain and disability. Magnetic resonance imaging (MRI), magnetic resonance arthrography (MRA) and ultrasound (US) are increasingly being used to assess the presence and size of rotator cuff tears to assist in planning surgical treatment. It is not known whether one imaging method is superior to any of the others. OBJECTIVES To compare the diagnostic test accuracy of MRI, MRA and US for detecting any rotator cuff tears (i.e. partial or full thickness) in people with suspected rotator cuff tears for whom surgery is being considered. SEARCH METHODS We searched the Cochrane Register of Diagnostic Test Accuracy Studies, MEDLINE, EMBASE, and LILACS from inception to February 2011. We also searched trial registers, conference proceedings and reference lists of articles to identify additional studies. No language or publication restrictions were applied. SELECTION CRITERIA We included all prospective diagnostic accuracy studies that assessed MRI, MRA or US against arthroscopy or open surgery as the reference standard, in people suspected of having a partial or full thickness rotator cuff tear. We excluded studies that selected a healthy control group, or participants who had been previously diagnosed with other specific causes of shoulder pain such as osteoarthritis or rheumatoid arthritis. Studies with an excessively long period (a year or longer) between the index and reference tests were also excluded. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data on study characteristics and results of included studies, and performed quality assessment according to QUADAS criteria. Our unit of analysis was the shoulder. For each test, estimates of sensitivity and specificity from each study were plotted in ROC space and forest plots were constructed for visual examination of variation in test accuracy. Meta-analyses were performed using the bivariate model to produce summary estimates of sensitivity and specificity. We were unable to formally investigate potential sources of heterogeneity because of the small number of studies. MAIN RESULTS We included 20 studies of people with suspected rotator cuff tears (1147 shoulders), of which six evaluated MRI and US (252 shoulders), or MRA and US (127 shoulders) in the same people. Many studies had design flaws, with the potential for bias, thus limiting the reliability of their findings. Overall, the methodological quality of the studies was judged to be low or unclear. For each test, we observed considerable heterogeneity in study results, especially between studies that evaluated US for the detection of full thickness tears and studies that evaluated MRA for the detection of partial thickness tears. The criteria for a positive diagnostic test (index tests and reference standard) varied between studies.Meta-analyses were not possible for studies that assessed MRA for detection of any rotator cuff tears or partial thickness tears. We found no statistically significant differences in sensitivity or specificity between MRI and US for detecting any rotator cuff tears (P = 0.13), or for detecting partial thickness tears (P = 1.0). Similarly, for the comparison between MRI, MRA and US for detecting full thickness tears, there was no statistically significant difference in diagnostic performance (P = 0.7). For any rotator cuff tears, the summary sensitivity and specificity were 98% (95% CI 92% to 99%) and 79% (95% CI 68% to 87%) respectively for MRI (6 studies, 347 shoulders), and 91% (95% CI 83% to 95%) and 85% (95% CI 74% to 92%) respectively for US (13 studies, 854 shoulders). For full thickness tears, the summary sensitivity and specificity were 94% (95% CI 85% to 98%) and 93% (95% CI 83% to 97%) respectively for MRI (7 studies, 368 shoulders); 94% (95% CI 80% to 98%) and 92% (95% CI 83% to 97%) respectively for MRA (3 studies, 183 shoulders); and 92% (95% CI 82% to 96%) and 93% (95% CI 81% to 97%) respectively for US (10 studies, 729 shoulders).Because few studies were direct head-to-head comparisons, we could not perform meta-analyses restricted to these studies. The test comparisons for each of the three classifications of the target condition were therefore based on indirect comparisons which may be prone to bias due to confounding. AUTHORS' CONCLUSIONS MRI, MRA and US have good diagnostic accuracy and any of these tests could equally be used for detection of full thickness tears in people with shoulder pain for whom surgery is being considered. The diagnostic performance of MRI and US may be similar for detection of any rotator cuff tears. However, both MRI and US may have poor sensitivity for detecting partial thickness tears, and the sensitivity of US may be much lower than that of MRI. The strength of evidence for all test comparisons is limited because most studies were small, heterogeneous and methodologically flawed, and there were few comparative studies. Well designed studies that directly compare MRI, MRA and US for detection of rotator cuff tears are needed.

Abstract
BACKGROUND Injuries of the posterior cruciate ligament (PCL) of the knee frequently occur in automobile accidents and sports injuries, although they are less frequent overall than injuries of the anterior cruciate ligament (ACL). Some patients show significant symptoms and subsequent articular deterioration, while others are essentially asymptomatic, maintaining habitual function. Management of PCL injuries remains controversial and prognosis can vary widely. Interventions extend from non-operative (conservative) procedures to reconstruction of the PCL, in the hope that the surgical procedure may have a positive effect in the reduction/prevention of future osteoarthritic changes in the knee. OBJECTIVES To determine the effectiveness and safety of surgical and conservative interventions for PCL injuries in adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (April 2004), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2004), MEDLINE via PubMed (1966 to April 2004), EMBASE (1966 to April 2004), CINAHL (1982 to April 2004), LILACS (1982 to April 2004), SportsDiscus (1975 to April 2004), and reference lists of articles. SELECTION CRITERIA Randomized or quasi-randomized clinical trials comparing various methods of operative and conservative interventions, and comparisons with each other for the treatment of PCL injuries. DATA COLLECTION AND ANALYSIS References found with the search strategy were evaluated independently by two review authors. MAIN RESULTS No randomized or quasi-randomized controlled studies meeting the selection criteria were identified. AUTHORS' CONCLUSIONS Future research should include randomized controlled trials of acute isolated PCL injuries, or PCL injuries when combined with other ligament injuries of the knee, treated operatively and conservatively. Adequate numbers of patients and an objective methodology for patient evaluation must be used in future studies of these interventions to determine the long-term results.

Abstract
BACKGROUND Achilles tendinitis is one of the most common of all sports injuries. There is no consensus on treatment. OBJECTIVES To assess the effectiveness of various treatment interventions for acute and chronic Achilles tendinitis in adults. SEARCH STRATEGY The Cochrane Bone, Joint and Muscle Trauma Group specialised register (December 2000), Cochrane Controlled Trials Register (The Cochrane Library Issue 4, 2000), MEDLINE (1966 to December 2000), EMBASE (1980 to 2001 wk 04), CINAHL (1982 to December 2000), and reference lists of identified trials were searched. SELECTION CRITERIA Randomised or quasi-randomised trials of treatment interventions for acute and chronic Achilles tendinitis in adults. Studies focusing on pathological tendinitis were excluded. Excluded were those trials that compared different dosages of the same drug or drugs within the same class of drugs, for example different non-steroidal anti-inflammatory drugs (NSAIDs). DATA COLLECTION AND ANALYSIS Three reviewers independently assessed trial quality, by use of a ten item check list, and extracted data. Requests were sent for separate data for Achilles tendinitis patients in studies within trials of mixed patient populations. Where possible, quantitative analysis and limited pooling of data were undertaken. MAIN RESULTS Nine trials, involving 697 patients, met the inclusion criteria of the review. Methodological quality was adequate in most of the trials with regards to blinding but the assessment of outcome was incomplete and short-term.There was weak but not robust evidence from three trials of a modest benefit of NSAIDs for the alleviation of acute symptoms. There was some weak evidence of no difference compared with no treatment of low dose heparin, heel pads, topical laser therapy and peritendonous steroid injection, but this could not be fully evaluated from the reports of four trials. The results of an experimental preparation of a calf-derived deproteinized haemodialysate, Actovegin, were promising but the severity of patient symptoms was questionable in the single small trial testing this comparison. The results of a comparison of glycosaminoglycan sulfate with a NSAID were inconclusive. AUTHORS' CONCLUSIONS There is insufficient evidence from randomised controlled trials to determine which method of treatment is the most appropriate for the treatment of acute or chronic Achilles tendinitis. Further research is warranted.

Abstract
BACKGROUND Ultrasound is used in the treatment of a wide variety of musculoskeletal disorders, which include acute ankle sprains. This is an update of a Cochrane review first published in 1999, and previously updated in 2004. OBJECTIVES To evaluate the effects of ultrasound therapy in the treatment of acute ankle sprains. SEARCH STRATEGY We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (September 2010), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2010, Issue 3), MEDLINE (1966 to September 2010), EMBASE (1983 to September 2010), CINAHL (1982 to 2004), and PEDro - the Physiotherapy Evidence Database (accessed 01/06/09). We also searched the Cochrane Rehabilitation and Related Therapies Field database, reference lists of articles, and contacted colleagues.The WHO International Clinical Trials Registry Platform was searched for ongoing trials. SELECTION CRITERIA Randomised or quasi-randomised trials were included if the following conditions were met: at least one study group was treated with therapeutic ultrasound; participants had acute lateral ankle sprains; and outcome measures included general improvement, pain, swelling, functional disability, or range of motion. DATA COLLECTION AND ANALYSIS Two authors independently performed study selection, and assessed the risk of bias and extracted data. Risk ratios and risk differences together with 95% confidence intervals were calculated for dichotomous outcomes and mean differences together with 95% confidence intervals for continuous outcome measures. Limited pooling of data was undertaken where there was clinical homogeneity in terms of participants, treatments, outcomes, and follow-up time points. MAIN RESULTS Six trials were included, involving 606 participants. Five trials included comparisons of ultrasound therapy with sham ultrasound; and three trials included single comparisons of ultrasound with three other treatments. The assessment of risk of bias was hampered by poor reporting of trial methods and results. None of the five placebo-controlled trials (sham ultrasound) demonstrated statistically significant differences between true and sham ultrasound therapy for any outcome measure at one to four weeks of follow-up. The pooled risk ratio for general improvement at one week was 1.04 (random-effects model, 95% confidence interval 0.92 to 1.17) for active versus sham ultrasound. The differences between intervention groups were generally small, between zero and six per cent, for most dichotomous outcomes. AUTHORS' CONCLUSIONS The evidence from the five small placebo-controlled trials included in this review does not support the use of ultrasound in the treatment of acute ankle sprains. The potential treatment effects of ultrasound appear to be generally small and of probably of limited clinical importance, especially in the context of the usually short-term recovery period for these injuries. However, the available evidence is insufficient to rule out the possibility that there is an optimal dosage schedule for ultrasound therapy that may be of benefit.

Abstract
BACKGROUND The anterior cruciate ligament (ACL) is the most frequently injured ligament of the knee. The ACL may be damaged in isolation but often other ligaments and menisci are implicated. The injury may be managed surgically or conservatively. Injury causes pain, effusion and inflammation leading to alteration in muscle function. Regaining muscular control is essential if the individual wishes to return to pre-injury level of function and patients will invariably be referred for rehabilitation. OBJECTIVES To present the best evidence for effectiveness of exercise used in the treatment of ACL injuries in combination with collateral ligament and meniscal damage to the knee in adults, on return to work and pre-injury levels of activity. SEARCH STRATEGY We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (October 2006), Cochrane Central Register of Controlled Trials (The Cochrane Library 2006, Issue 3), MEDLINE (1996 to October 2006), EMBASE (1980 to October 2006), other databases and reference lists of articles. SELECTION CRITERIA We included randomised controlled trials and quasi-randomised trials testing exercise programmes designed to treat adults with ACL injuries in combination with collateral ligament and meniscal damage. Included trials randomised participants to receive any combination of the following: no care, usual care, a single-exercise intervention, and multiple-exercise interventions. The primary outcome measures of interest were returning to work and return to pre-injury level of activity post treatment, at six months and one year. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted data. Study authors were contacted for additional information. Adverse effects information was collected from the trials. MAIN RESULTS Five trials (243 participants) evaluated different exercise programmes following ACL reconstruction and one trial (100 participants) compared supervised with self-monitored exercises as part of conservative treatment. No study compared the effect of exercise versus no exercise. Methodological quality scores varied considerably across the trials; participant and assessor blinding were poorly reported. Pooling of data was rarely possible due to the wide variety of comparisons, outcome measures and time points reported, and lack of appropriate data. Insufficient evidence was found to support the efficacy of one exercise intervention over another. AUTHORS' CONCLUSIONS This review has demonstrated an absence of evidence to support one form of exercise intervention over another. Further research should be considered in the form of large scale well-designed and well-reported randomised controlled trials with suitable outcome measures and surveillance periods. Suitable outcome measures should include a measure of functional outcome relevant to the individual.

Abstract
BACKGROUND The anterior cruciate ligament (ACL) is the most frequently injured ligament of the knee. Injury causes pain, effusion and inflammation leading to the inability to fully activate the thigh muscles. Regaining muscular control is essential if the individual wishes to return to pre-injury level of function and patients will invariably be referred for rehabilitation. OBJECTIVES To present the best evidence for effectiveness of exercise used in the rehabilitation of isolated ACL injuries in adults, on return to work and pre-injury levels of activity. SEARCH STRATEGY We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (Feb 2005), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 1, 2005), MEDLINE (1996 to March 2005), EMBASE (1980 to March 2005), other databases and reference lists of articles. SELECTION CRITERIA Randomised controlled trials and quasi-randomised trials testing exercise programmes designed to rehabilitate adults with isolated ACL injuries. Trials where participants were randomised to receive any combination of the following: no care, usual care, a single-exercise intervention, and multiple-exercise interventions, were included. The primary outcome measures of interest were returning to work and return to pre-injury level of activity post treatment, at six months and one year. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted data. Study authors were contacted for additional information. Adverse effects information was collected from the trials. MAIN RESULTS Nine trials involving 391 participants were included. Only two trials, involving 76 participants, reported conservative rehabilitation and seven trials, involving 315 participants, evaluated rehabilitation following ACL reconstruction. Methodological quality scores varied considerably across the trials, with the nature of participant and assessor blinding poorly reported. Trial comparisons fell into six categories. Pooling of data was rarely possible due to lack of appropriate data as well as the wide variety in outcome measures and time points reported. Insufficient evidence was found to support the efficacy of one exercise intervention over another. AUTHORS' CONCLUSIONS This review has demonstrated an absence of evidence to support one form of exercise intervention against another and the use of supplementary exercises in the management of isolated ACL injuries. Further research in the form of large scale well designed randomised controlled trials with suitable outcome measures and surveillance periods, using standardised reporting should be considered.

Abstract
BACKGROUND Some sports, for example basketball and soccer, have a very high incidence of ankle injuries, mainly sprains. Consequently, ankle sprains are one of the most commonly treated injuries in acute care. OBJECTIVES To assess the effects of interventions used for the prevention of ankle ligament injuries or sprains in physically active individuals from adolescence to middle age. SEARCH STRATEGY We searched the Cochrane Bone, Joint and Muscle Trauam Group's specialised register, MEDLINE, PubMed, EMBASE, CINAHL, the National Research Register and bibliographies of study reports. We also contacted colleagues and some trialists. The most recent search was conducted in July 2000. SELECTION CRITERIA Randomised or quasi-randomised trials of interventions for the prevention of ankle sprains in physically active individuals from adolescence to middle age were included provided that ankle sprains were recorded. Interventions included use of modified footwear, external ankle supports, co-ordination training and health education. These could be applied as a supplement to treatment provided that prevention of re-injury was the primary objective. DATA COLLECTION AND ANALYSIS At least two reviewers independently assessed methodological quality and extracted data. Wherever possible, results of outcome measures were pooled and sub-grouped by history of previous sprain. Relative risks (RR) and 95% confidence intervals (95% CI) are reported for individual and pooled data. MAIN RESULTS In this review update, a further nine new trials were included. Overall, 14 randomised trials with data for 8279 participants were included. Twelve trials involved active, predominantly young, adults participating in organised, generally high-risk, activities. The other two trials involved injured patients who had been active in sports before their injury. The prophylactic interventions under test included the application of an external ankle support in the form of a semi-rigid orthosis (three trials), air-cast brace (one trial) or high top shoes (one trial); ankle disk training; taping; muscle stretching; boot inserts; health education programme and controlled rehabilitation.The main finding was a significant reduction in the number of ankle sprains in people allocated external ankle support (RR 0.53, 95% CI 0.40 to 0.69). This reduction was greater for those with a previous history of ankle sprain, but still possible for those without prior sprain. There was no apparent difference in the severity of ankle sprains or any change to the incidence of other leg injuries. The protective effect of 'high-top' shoes remains to be established.There was limited evidence for reduction in ankle sprain for those with previous ankle sprains who did ankle disk training exercises. Various problems with data reporting limited the interpretation of the results for many of the other interventions. AUTHORS' CONCLUSIONS This review provides good evidence for the beneficial effect of ankle supports in the form of semi-rigid orthoses or air-cast braces to prevent ankle sprains during high-risk sporting activities (e.g. soccer, basketball). Participants with a history of previous sprain can be advised that wearing such supports may reduce the risk of incurring a future sprain. However, any potential prophylactic effect should be balanced against the baseline risk of the activity, the supply and cost of the particular device, and for some, the possible or perceived loss of performance.Further research is indicated principally to investigate other prophylactic interventions, their cost-effectiveness and general applicability.

Abstract
BACKGROUND Postoperative rehabilitation of the flexor tendons in the hand consists of a short period of immobilisation while pain and swelling diminish, followed by progressive mobilisation to maximize the range of motion of the affected fingers. By altering the time of immobilisation and the manner of subsequent mobilisation different rehabilitation regimes are created. OBJECTIVES To determine, with evidence from randomised controlled trials, the optimal rehabilitation strategy after surgery for flexor tendon injuries in the hand. SEARCH STRATEGY We searched the Cochrane Bone, Joint and Muscle Trauma Group specialised register (November 2002), the Cochrane Central Register of Controlled Trials (The Cochrane Library, issue 4, 2002), MEDLINE (1966 to November 2002), EMBASE (1988 to November 2002), CINAHL (1982 to October 2002), CURRENT CONTENTS (1993 to October 2002), PEDro - The Physiotherapy Evidence Database (http://ptwww.cchs.usyd.edu.au/pedro/ accessed 30/10/2002) and reference lists of articles. SELECTION CRITERIA All randomised and quasi-randomised controlled trials of interventions for rehabilitation after surgery of flexor tendon injuries in the hand after surgery. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed trial quality, using a 10 item scale, and extracted data where possible. Additional information was sought from trialists when required. Due to the lack of extractable data and the variety of interventions used, pooling was not attempted. Where possible relative risks and 95 per cent confidence intervals were calculated for dichotomous outcomes, and mean differences and 95 per cent confidence intervals calculated for continuous outcomes. MAIN RESULTS Six trials, including three reported only in abstracts, with a total of 464 participants were included. Data were not pooled. One trial compared continuous passive motion (CPM) with controlled intermittent passive motion (CIPM) and found a significant difference in mean active motion favouring CPM (WMD 19.00 degrees, 95% CI 15.11 to 22.89). One trial compared a shortened passive flexion/active extension programme with a normal passive flexion/active extension mobilisation programme, and reported (without data) a significant reduction in absence from work of 2.1 weeks in favour of the shortened programme. Other trials compared active flexion with rubber band traction, early controlled active mobilisation with early controlled passive mobilisation and dynamic splintage versus static splintage. No trials found significant differences in overall functioning or complication rate. AUTHORS' CONCLUSIONS Controlled mobilisation regimens are widely employed in rehabilitation after flexor tendon repair in the hand. This review found insufficient evidence from randomised controlled trials to define the best mobilisation strategy.

Abstract
BACKGROUND Treatments for managing articular cartilage defects of the knee, including drilling and abrasion arthroplasty, are not always effective. When they are, long-term benefits may not be maintained and osteoarthritis may develop. An alternative is autologous chondrocyte implantation (ACI), the surgical implantation of healthy cartilage cells into the damaged areas. OBJECTIVES To determine the efficacy and safety of ACI in people with full thickness articular cartilage defects of the knee. SEARCH STRATEGY We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (3 December 2008), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2008, Issue 4), MEDLINE (1950 to November Week 3 2008), EMBASE (1980 to Week 48 2008), SPORTDiscus (3 December 2008), the WHO International Clinical Trials Registry Platform (4 December 2008), and Current Controlled Trials (3 December 2008). SELECTION CRITERIA Randomised and quasi-randomised trials comparing ACI with any other type of treatment (including no treatment or placebo) for symptomatic cartilage defects of the medial or lateral femoral condyle, femoral trochlea or patella. DATA COLLECTION AND ANALYSIS Review authors selected studies for inclusion independently. We assessed risk of bias based on adequacy of the randomisation and allocation concealment process, potential for selection bias after allocation and level of masking. We did not pool data due to clinical and methodological heterogeneity. MAIN RESULTS Six heterogeneous trials were identified with 431 participants. Methodological flaws of the included trials included incomplete follow-up and inadequate reporting of outcomes. Three trials compared ACI versus mosaicplasty. One reported statistically significant results in favour of ACI at one year in the numbers of people with 'good' or 'excellent' functional results. Conversely, another trial found significant improvement for the mosaicplasty group when assessed using one functional scoring system at two years, but no statistically significant differences based on two other scoring systems. A third trial found no difference between ACI and mosaicplasty, 10 months on average after the surgery.There was no statistically significant difference in functional outcomes at two years in single trials comparing ACI with microfracture or characterised chondrocyte implantation versus microfracture. The results of the sixth trial comparing matrix-guided ACI versus microfracture were undermined by the severe loss to follow-up. AUTHORS' CONCLUSIONS There is insufficient evidence to draw conclusions on the use of ACI for treating full thickness articular cartilage defects in the knee. Further good quality randomised controlled trials with long-term functional outcomes are required.

Abstract
BACKGROUND Heterotopic ossification (HO) is the formation of mature lamellar bone in soft tissue sites outside the skeleton. HO frequently complicates burns, arthroplasty, fractures, and spinal cord and brain injuries. It can impair joint function. OBJECTIVES To determine the efficacy of medications to treat acute HO on radiological, symptomatic, functional impairment, and disability outcomes. SEARCH STRATEGY We searched the Cochrane Bone, Joint and Muscle Trauma Group specialised register, the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 2, 2004), MEDLINE (1966 to August 2004), EMBASE (1980 to August 2004), CINAHL (1982 to August 2004), other databases, reference lists of articles, and contacted trialists and drug companies. No language restrictions were applied. SELECTION CRITERIA All randomised or quasi-randomised controlled trials that assessed the efficacy of any medication for treating acute HO (confirmed by bone scintigraphy, radiography, ultrasonography, or biopsy) and which used radiography to grade post-treatment HO severity. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed the study quality and extracted data. We analysed two dichotomous outcomes: no progression in HO grade (versus progression) and improvement in HO grade (versus no improvement). MAIN RESULTS Two randomised trials comparing disodium etidronate versus placebo were included (Ono 1988; Stover 1976), from which ninety-two participants with spinal cord injury had radiographically-proven HO at baseline. At the completion of the 12 week intervention, the Ono study but not the Stover study, suggested that disodium etidronate was associated with a significantly greater likelihood of successfully preventing the progression of radiographic HO grade, (relative risk (RR) 1.50; 95% confidence interval (CI) I 1.16 to 1.93; and RR 1.48; 95% CI 0.78 to 2.84 respectively) and a significantly greater likelihood of improvement in HO grade (RR 2.78; 95% CI 1.66 to 4.66; and RR 0.71; 95% CI 0.20 to 2.53 respectively). There was evidence of statistical heterogeneity for the latter outcome. Longer term radiographic, clinical or side effect outcomes were unavailable. Data was not pooled due to this heterogeneity and the inadequate duration of follow up. AUTHORS' CONCLUSIONS Given the absence of long term radiographic outcomes in the included studies, there is insufficient evidence to recommend the use of disodium etidronate or other pharmacological agents for the treatment of acute HO. It has been previously suggested that disodium etidronate acts by delaying, rather than preventing, the mineralization of HO, and that mineralization may occur after treatment cessation in many cases, thereby negating the benefit of disodium etidronate on eventual HO grade. Further studies are required to assess all pharmacological treatments for acute HO with sufficient follow-up duration.

Abstract
BACKGROUND Surgical site infection and other hospital-acquired infections cause significant morbidity after internal fixation of fractures. The administration of antibiotics may reduce the frequency of infections. OBJECTIVES To determine whether the prophylactic administration of antibiotics in people undergoing surgical management of hip or other closed long bone fractures reduces the incidence of surgical site and other hospital-acquired infections. SEARCH STRATEGY We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (December 2009), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2009, Issue 4), MEDLINE (1950 to November 2009), EMBASE (1988 to December 2009), other electronic databases including the WHO International Clinical Trials Registry Platform (December 2009), conferences proceedings and reference lists of articles. SELECTION CRITERIA Randomised or quasi-randomised controlled trials comparing any regimen of systemic antibiotic prophylaxis administered at the time of surgery, compared with no prophylaxis, placebo, or a regimen of different duration, in people with a hip fracture undergoing surgery for internal fixation or prosthetic replacement, or with any closed long bone fracture undergoing internal fixation. All trials needed to report surgical site infection. DATA COLLECTION AND ANALYSIS Two authors independently screened papers for inclusion, assessed risk of bias and extracted data. Pooled data are presented graphically. MAIN RESULTS Data from 8447 participants in 23 studies were included in the analyses. In people undergoing surgery for closed fracture fixation, single dose antibiotic prophylaxis significantly reduced deep surgical site infection (risk ratio 0.40, 95% CI 0.24 to 0.67), superficial surgical site infections, urinary infections, and respiratory tract infections. Multiple dose prophylaxis had an effect of similar size on deep surgical site infection (risk ratio 0.35, 95% CI 0.19 to 0.62), but significant effects on urinary and respiratory infections were not confirmed. Although the risk of bias in many studies as reported was unclear, sensitivity analysis showed that removal from the meta-analyses of studies at high risk of bias did not alter the conclusions. Economic modelling using data from one large trial indicated that single dose prophylaxis with ceftriaxone is a cost-effective intervention. Data for the incidence of adverse effects were very limited, but as expected they appeared to be more common in those receiving antibiotics, compared with placebo or no prophylaxis. AUTHORS' CONCLUSIONS Antibiotic prophylaxis should be offered to those undergoing surgery for closed fracture fixation.
