Effect of negative pressure wound therapy on the incidence of deep surgical site infections after orthopedic surgery: a meta-analysis and systematic review. J Orthop Surg Res 2024; 19:555. [PMID: 39252068 PMCID: PMC11385841 DOI: 10.1186/s13018-024-05038-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2024] [Accepted: 08/27/2024] [Indexed: 09/11/2024] Open
Abstract
OBJECTIVE This meta-analysis aimed to explore the impact of prophylactic negative pressure wound therapy (NPWT) on the occurrence of deep surgical site infections (SSIs) following orthopedic surgery. METHODS A systematic search was conducted across Medline, Embase, Cochrane Library, and Web of Science databases for articles concerning NPWT in patients who underwent orthopedic surgery up to May 20, 2024. Using Stata 15.0, the combined odds ratios (ORs) were calculated with either a random-effects model or a fixed-effects model, depending on the heterogeneity values. RESULTS From a total of 440 publications, studies that utilized NPWT as the experimental group and conventional dressings as the control group were selected to analyze their impact on SSIs. Ultimately, 32 studies met the inclusion criteria. These included 12 randomized controlled trials and 20 cohort studies, involving 7454 patients, with 3533 of whom received NPWT and 3921 of whom were treated with conventional dressings. The results of the meta-analysis demonstrated that the NPWT group had a lower incidence of deep SSIs in orthopedic surgeries than did the control group [OR 0.64, 95% CI (0.52, 0.80), P = 0.0001]. Subgroup analysis indicated a notable difference for trauma surgeries [OR 0.65, 95% CI (0.50, 0.83), P = 0.001], whereas joint surgeries [OR 0.65, 95% CI (0.38, 1.12), P = 0.122] and spine surgeries [OR 0.61, 95% CI (0.27, 1.35), P = 0.221] did not show significant differences. Additionally, when examined separately according to heterogeneity, trauma surgeries exhibited a significant difference [OR 0.50, 95% CI (0.31, 0.80), P = 0.004]. CONCLUSION The results of our study indicate that the prophylactic use of NPWT reduces the incidence of deep SSIs following orthopedic trauma surgery when compared to the use of conventional dressings. We postulate that the prophylactic application of NPWT in patients at high risk of developing complications from bone trauma may result in improved clinical outcomes and an enhanced patient prognosis.

Abstract
Introduction In severe extremity trauma involving large tissue defects, early closure (e.g., free-flap surgery) of the defects is an essential step for good functional reconstruction; however, in some cases, early closure may be difficult. Highly concentrated carbon dioxide bathing, used to improve blood flow in ischemic limbs and skin ulcers, can also be applied in wound bed preparation for severe limb trauma. Patients and Methods The three cases in this study required an average of 13 weeks of highly concentrated carbonated bathing, which led to significantly better wound bed preparation, even in the exposed bone and tendon regions. Results We successfully achieved good functional limb reconstruction in patients with deep burns and severe open fractures by reducing wound infection and facilitating good wound bed preparation. Conclusions Highly concentrated carbon dioxide bathing was sufficient to prevent frequent wound infections, even in severe extremity trauma involving large soft-tissue defects such as deep crush burns and Gustilo Anderson classification ≥3b open fractures of the extremities. To our knowledge, such interventions have not been reported in the past and are valuable as new procedures for wound bed preparation in severe extremity trauma from both cost and wound infection control perspectives.

J Orthop Trauma 2024; 38:e207-e213. [PMID: 38470128 DOI: 10.1097/bot.0000000000002797] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Accepted: 03/04/2024] [Indexed: 03/13/2024]
Abstract
OBJECTIVES Intramedullary nailing is the treatment of choice for most tibial shaft fractures (TSF). However, an iatrogenic pitfall may be rotational malalignment. The aim of this retrospective analysis was to determine predictors of rotational malalignment following intramedullary nailing of TSF. METHODS DESIGN Retrospective study. SETTING Single level 1 trauma center. PATIENT SELECTION CRITERIA Patients who had a unilateral intramedullary nailing for TSF with a low-dose bilateral postoperative CT to assess rotational malalignment. OUTCOME MEASURES AND COMPARISONS Bivariable analysis followed by multivariable analysis was then undertaken to assess for any independent predictors, such as fracture type/sight, surgeon experience, and side of fracture, predictive of rotational malalignment. RESULTS In total, 154 patients (71% male, median age 37 years) were included in this study. Thirty-nine percent of variability in postoperative rotational malalignment could be explained using a model including (increased) tibial torsion of the noninjured side (mean [38.9 degrees ± 9.02 degrees] considered normal tibial torsion), side of tibial fracture, and spiral-type tibial fracture (R2 = 0.39, P ≤ 0.001, F = 31.40). In this model, there was a negative linear association between degrees of torsion on the noninjured side and rotational malalignment (-0.45, P < 0.001)-as baseline torsion increased from mean by 1 degree, malrotation in the opposite direction of 0.54 degrees seen. Positive linear associations between right-sided TSF and rotational malalignment (8.59 P < 0.001) as well as spiral fractures and rotational malalignment (5.03, P < 0.01) were seen. CONCLUSIONS This study demonstrates that baseline reduced (internal) tibial torsion of the noninjured limb, spiral fractures, and right-sided TSF are predictive of postoperative external rotational malalignment. Conversely, increased baseline (external) tibial torsion of the noninjured limb and left-sided TSF are predictive of postoperative internal rotational malalignment. Surgeons may use this regression model preoperatively to predict what sort of postoperative rotational difference their patient may be prone to. LEVEL OF EVIDENCE Prognostic Level III.

Incisional negative pressure wound therapy may not protect against post-operative surgical site complications in bicondylar tibial plateau fractures. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:1173-1181.

Abstract
PURPOSE To determine if incisional negative pressure wound therapy is protective against post-operative surgical site complications following definitive fixation of bicondylar tibial plateau fractures. METHODS A retrospective analysis of patients diagnosed with an acute bicondylar tibial plateau fracture (AO/OTA 41-C) undergoing ORIF from 2010 to 2020 was performed. Patients received either a standard sterile dressing (SD) or incisional negative pressure wound therapy (iNPWT). Primary outcomes included surgical site infection, osteomyelitis, and wound dehiscence. Secondary outcomes included non-union and return to the operating room. Multivariate logistic regression analyses were performed. RESULTS 180 patients were included and 22% received iNPWT (n = 40) and 78% received standard dressings (n = 140). iNPWT was more common in active smokers (24.7% vs. 19.3%, p = 0.002) and the SD group was more likely to be lost to follow up (3.6% vs. 0%, p = 0.025). iNPWT was not protective against infection or surgical site complications, and in fact, was associated with higher odds of post-operative infection (OR: 8.96, p = 0.005) and surgical site complications (OR:4.874, p = 0.009) overall. Alcohol abuse (OR: 19, p = 0.005), tobacco use (OR: 4.67, p = 0.009), and time to definitive surgery (OR = 1.21, p = 0.033) were all independent risk factors for post-operative infection. CONCLUSION In this series of operatively treated bicondylar tibial plateau fractures, iNPWT did not protect against post-operative surgical site complications compared to conventional dressings. Tobacco use, alcohol abuse, and time to definitive surgery, were independent risk factors for post-operative infection. Further studies are needed to determine if iNPWT offers a protective benefit in exclusively high-risk patients with relevant medical and social history.

Abstract
The results of this meta-analysis were applied to analyse the effects of Negative Pressure Wound Therapy (NPWT) and conventional dressings on post-surgical outcomes after trauma in orthopaedics. Through June 2023, a full review of the literature has been carried out with the help of 4 databases, PubMed, Embase, Cochrane Library, and the Web of Science. The quality of the literature was evaluated according to the classification and exclusion criteria established for this trial, which led to an analysis of 9 related trials. The results included the injury was deeply and superficially infected, and the wound was dehiscence. The 95% confidence interval (CI) and odds ratios (OR) were computed by means of a fixed-effect and a random-effect model. Meta-analyses were conducted with RevMan 5.3. There is no statistical significance between NPWT and routine therapy for deep wound infection (OR, 1.37; 95% CI, 0.82-2.27, p = 0.23); There was no difference in the incidence of inflammation in the wound than with conventional dressings (OR, 1.10; 95% CI, 0.84-1.45, p = 0.49); But NPWT was obviously superior to that of routine therapy in superficial wound infection (OR, 2.07; 95% CI, 1.32-3.25, p = 0.002) and wound dehiscence (OR, 2.44; 95% CI, 1.31-4.57, p = 0.005); But not with respect to wound exudate. therapy group, but no statistically significant difference was found with respect to wound exudation. (OR, 1.16; 95% CI, 0.86-1.57, p = 0.34). Given that some of the chosen trials are too small for this meta-analysis, caution should be exercised when treating their values. More high-quality research with a large sample is required in order to confirm the findings.

Abstract
PURPOSE Skin closure disorders in ankle surgery are a recurrent problem not only in traumatology but also in elective surgery. The aim of the study was to describe the anatomical basis of the fasciocutaneous vascularization of the lateral malleolus region to develop a posterior cover flap for the region. METHODS We dissected ten fresh frozen specimens after arterial injection of an Indian ink preparation and individualized the perforating arteries. Their positions and diameters were collated. Then, the surgical technique was clinically applied for two different cases by transferring the fasciocutaneous flap posterior to the lateral malleolus to cover a loss of skin substance. RESULTS There were in average 5 fibular perforators over the last 100 mm of the fibula. The average diameter of the first two perforating arteries was 0.6 ± 0.12 mm and 0.9 ± 0.25 mm, respectively, and the consistency of the latter makes it possible to produce a skin flap with anterior translation. This is an axial flap. Two patients were operated on using this technique. There was no necrosis of the posterior fibular flap and healing was achieved by the third post-operative week. CONCLUSION This study showed the presence of fibular perforating arteries with a high reproducibility of their dissection. This anatomical description served as the basis for the description of a new distal fibular perforating flap.

Abstract
Introduction Neuropathic pain is prevalent among people after lower limb fracture surgery and is associated with lower health-related quality of life and greater disability. This study estimates the financial cost and pain medication use associated with neuropathic pain in this group. Methods A secondary analysis using pain data collected over six postoperative months from participants randomised in the Wound Healing in Surgery for Trauma (WHiST) trial. Pain states were classified as pain-free, chronic non-neuropathic pain (NNP) or chronic neuropathic pain (NP). Cost associated with each pain state from a UK National Health Service (NHS) and personal social services (PSS) perspective were estimated by multivariate models based on multiple imputed data. Pain medication usage was analysed by pain state. Results A total of 934 participants who provided either 3- or 6-months pain data were included. Compared to participants with NP, those with NNP (adjusted mean difference -£730, p = 0.38, 95% CI -2368 to 908) or were pain-free (adjusted mean difference -£716, p = 0.53, 95% CI -2929 to 1497) had lower costs from the NHS and PSS perspective in the first three postoperative months. Over the first three postoperative months, almost a third of participants with NP were prescribed opioids and 8% were prescribed NP medications. Similar trends were observed by 6 months postoperatively. Conclusion This study found healthcare costs were higher amongst those with chronic NP compared to those who were pain-free or had chronic NNP. Opioids, rather than neuropathic pain medications, were commonly prescribed for NP over the first six postoperative months, contrary to clinical guidelines.

Abstract
INTRODUCTION Despite the improvements in surgical techniques and the use of prophylactic intravenous antibiotics, the fracture-related infection (FRI) incidence after high-risk tibial plateau fractures remains high. This study aimed to evaluate the clinical effect of the intrawound application of vancomycin on the FRI after high-risk tibial plateau fracture surgery. METHODS A total of 243 patients who underwent high-risk tibial plateau fracture surgery from May 2013 to June 2021 were retrospectively reviewed. Of these, 233 cases were enrolled. Considering the preoperative patient condition, surgeons applied vancomycin powder directly into the surgical site before wound closure in 105 cases (intrawound application of vancomycin powder with preoperative intravenous cephalosporin). The remaining 128 cases served as the control group (preoperative intravenous cephalosporin alone). Clinical data and surgical details were recorded. The Cox proportional hazards regression analysis was used to assess risk factors for FRI. The Kaplan-Meier method and the log rank test illustrated the infection status of patients based on the application of intrawound vancomycin. The primary outcome was an FRI within one year. Secondary outcomes included bacterial culture and vancomycin-related complications. RESULTS Our study demonstrated a significant difference in the incidence of FRI between the vancomycin group and the control group (3.8% versus 10.9%; p=0.041). Multivariable Cox regression showed the intrawound application of vancomycin powder decreased the rate of FRI. There were no complications related to intrawound vancomycin observed during follow-up. The presence of Gram-positive FRI was higher in the control group compared with the vancomycin group. CONCLUSIONS Intrawound application of vancomycin was associated with a significant lower rate of FRI after high-risk tibial plateau fracture surgery compared to the control group.

Abstract
Ankle fracture is a common injury, and depending on injury severity, treatment may be a support boot, cast or surgery. Older people, particularly those with severe injuries who are asked to restrict weight bearing, struggle with early recovery. To elicit older peoples' experience of recovery 6 months after injury, we drew on a phenomenological approach using interviews. Findings revealed that getting on with life was a way of accepting what it feels like to 'be vulnerable', needing to 'be safe' while determinedly working hard to 'be myself'. Being vulnerable identified endurance of inactivity, loneliness and dependency in the non-weight bearing period of recovery, followed by a struggle to weight bear while lacking confidence and being fearful of falling and causing further damage. Being safe conveyed fragility where sensations, pain and stiffness acted as bodily reminders of injury. Lack of function and awareness of danger led to carefulness where planning or curtailing of activities ensured their safety. Being myself showed a determination to push away from a disrupted self-identify of being older or disabled while being challenged by the continuous process of learning to be more mobile. A lack of readiness for old age created a drive to age well. Despite loss of ability, participants hoped to regain their pre-injury way of living. This study challenges practice that disregards the hard work required to recover from ankle fracture. As comorbidity increases with age, failure to consider this aspect may contribute to frailty in this group of older people.

What Is the Safe Window from Definitive Fixation to Flap Coverage in Type 3B Open Tibia Fractures? Supporting Plastics and Orthopaedics Alliance in Reducing Trauma Adverse Events (SPARTA). J Orthop Trauma 2023; 37:103-108. [PMID: 36253901 DOI: 10.1097/bot.0000000000002509] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 10/12/2022] [Indexed: 11/07/2022]
Abstract
OBJECTIVES To delineate whether a "safe" window exists for timing from definitive fixation to definitive soft tissue coverage in the treatment of open tibial diaphyseal fractures requiring flap coverage. DESIGN International multicenter, retrospective comparative cohort study. PATIENTS/PARTICIPANTS Three hundred and seventy-three (n = 373) patients who sustained an open tibial shaft fracture requiring flap coverage. METHODS We evaluated the deep infection rates based on the timing between the definitive fixation and flap coverage. We determined several intervals of time from the day of definitive fixation (regardless of time from injury) and flap coverage. If performed on the same operative setting these were considered day 0. We evaluated coverage after 2 and 5 days from definitive fixation based on time versus infection rate curve inflection points. We adjusted for time to debridement and antibiotics within an hour. MAIN OUTCOME MEASUREMENT Deep infection after definitive fixation and flap coverage. RESULTS The mean age of the cohort was 42.4 years (SD = 18.2) and 270 were male (72.4%). The deep infection rate after flap coverage was 20.6% (77/373). Definitive fixation to flap coverage time of up to 2 days was not associated with an increased risk of infection [relative risk (RR) = 1.12; 95% confidence interval, 0.92-1.37; P = 0.26]. There was an increased risk of deep infection for more than 2 days (RR = 1.59) and >5 days (RR = 1.64). CONCLUSION This study observed a "safe" window of up to 2 days between definitive fixation and flap coverage in open tibial shaft fractures requiring coverage before a statistical increase in risk of deep infection rate occurred. LEVEL OF EVIDENCE Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Use of negative pressure wound therapy in patients with fracture-related infection more than doubles the risk of recurrence. Injury 2022; 53:3938-3944. [PMID: 36424686 DOI: 10.1016/j.injury.2022.10.014] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 07/11/2022] [Accepted: 10/16/2022] [Indexed: 11/05/2022]
Abstract
PURPOSE Fracture-related infection (FRI) is one of the most serious complications in orthopedic trauma surgery. Despite its widespread use, the role of Negative Pressure Wound Therapy (NPWT) remains controversial in the management pathway of FRI. The aim of this study was to assess the relationship between the application of NPWT and its duration and recurrence of infection in operatively treated FRI patients. PATIENTS AND METHODS This is a retrospective cohort study based on the FRI database of three level 1 Trauma Centres. Included patients had to be at least 16 years of age and surgically treated for FRI between January 1st 2015 and September 1st 2020. Patients were subdivided in either the NPWT group, when NPWT was applied as part of the FRI treatment, or in the control group, when no NPWT had been applied. To limit confounding, patients were excluded if they (also) underwent NPWT prior to the diagnosis of FRI. The relation between the duration of NPWT during FRI treatment and the recurrence rate of infection was analyzed using a multivariable logistic regression model. RESULTS A total of 263 patients were included, 99 in the NPWT group and 164 in the control group. The median duration of NPWT was 18.0 (IQR 15.8) days. In the NPWT group, 28 patients (28.3%) developed a recurrent FRI. In the control group, 19 patients (11.6%) had a recurrent FRI (p = 0.001, 95% CI [0.174 - 0.635]). In the NPWT group there were no significant differences in baseline characteristics between the recurrence and non-recurrence group. The duration of NPWT was associated with a higher risk of recurrence of infection (p = 0.013, OR 1.036, 95% CI [1.008 - 1.066]). CONCLUSION Delayed wound closure with the application of NPWT increased the risk of recurrence of infection in patients with soft tissue defects after FRI treatment. Therefore, it is advised to consider NPWT only as a short-term (e.g. few days) necessity to bridge the period until definitive wound closure can be established.

Negative Pressure Wound Therapy for Extremity Open Wound Management: A Review of the Literature. J Orthop Trauma 2022; 36:S6-S11.

Abstract
Negative pressure wound therapy (NPWT) with reticulated open cell foam is used commonly in orthopaedic trauma, particularly in the management of complex open fracture wounds. This article reviews the literature to date regarding this adjunctive treatment, particularly in regard to removal of infectious material, temporary management of wounds pending soft tissue reconstruction, combat wounds, and over split-thickness skin grafts. Mechanism of action is also reviewed, including stabilization of the wound environment, edema control, macrodeformation, and microdeformation effects. Use of NPWT as an adjunct in management of open fractures along with operative debridement, systemic antibiotics, and early soft tissue reconstruction are the highest yield interventions for managing open fracture wounds with infection. NPWT as an adjunct therapy in the protocol for open fractures seems to add additional clinical benefit for patients with severe open fracture wounds not amenable to primary, immediate closure.

Abstract
AIMS This study estimated trends in incidence of open fractures and the adherence to clinical standards for open fracture care in England. METHODS Longitudinal data collected by the Trauma Audit and Research Network were used to identify 38,347 patients with open fractures, and a subgroup of 12,170 with severe open fractures of the tibia, between 2008 and 2019 in England. Incidence rates per 100,000 person-years and 95% confidence intervals were calculated. Clinical care was compared with the British Orthopaedic Association Standards for Trauma and National Major Trauma Centre audit standards. RESULTS In total, 60% of all open fractures occurred in males; the median age was 48 years (interquartile range (IQR) 29 to 68). Between 2012 and 2019, the overall incidence in England was 6.94 per 100,000 person-years. In males, the highest incidence observed was in those aged 20 to 29 years (11.50 per 100,000 person-years); in females, incidence increased with age, peaking at 32.11/100,000 person-years at 90 years of age and over. Among those with severe open fractures of the tibia, there was a bimodal distribution in males, peaking at 20 to 29 years (3.71/100,000 person-years) and greater than 90 years of age (2.84/100,000 person-years) respectively; among females, incidence increased with age to a peak of 9.91/100,000 person years at 90 years of age and over. There has been variable improvement with time in the clinical care standards for patients with severe open fractures of the tibia. The median time to debridement was 13.0 hours (IQR 6.4 to 20.9); almost two-thirds of patients underwent definitive soft-tissue coverage within 72 hours from 2016 to 2019. CONCLUSION This is the first time the incidence of all open fractures has been studied using data from a national audit in England. While most open fractures occurred in young males, the incidence increased with age in females to a much greater level than observed in older males. The degree of missing data in the national audit is startling, and limits the certainty of inferences drawn concerning open fracture care. Cite this article: Bone Joint J 2022;104-B(6):736-746.

Abstract
PURPOSE This review provides an overview of the patent literature on posteriorly placed intrapedicular bone anchors. Conventional pedicle screws are the gold standard to create a fixation in the vertebra for spinal fusion surgery but may lack fixation strength, especially in osteoporotic bone. The ageing population demands new bone anchors that have an increased fixation strength, that can be placed safely, and, if necessary, can be removed without damaging the surrounding tissue. METHODS The patent search was conducted using a classification search in the Espacenet patent database. Only patents with a Cooperative Patent Classification of A61B17/70 or A61B17/7001 concerning spinal positioners and stabilizers were eligible for inclusion. The search query resulted in the identification of 731 patents. Based on preset inclusion criteria, a total of 56 unique patents on different anchoring methods were included, reviewed and categorized in this study. RESULTS Five unique fixation methods were identified; (1) anchors that use threading, (2) anchors that utilize a curved path through the vertebra, (3) anchors that (partly) expand, (4) anchors that use cement and (5) anchors that are designed to initiate bone ingrowth. Of the anchor designs included in this study, eight had a corresponding commercial product, six of which were evaluated in clinical trials. CONCLUSION This review provides insights into worldwide patented intrapedicular bone anchors that aim to increase the fixation strength compared to the conventional pedicle screw. The identified anchoring methods and their working principles can be used for clinical decision-making and as a source of inspiration when designing novel bone anchors.

Current practice in the measurement and interpretation of intervention adherence in randomised controlled trials: A systematic review. Contemp Clin Trials 2022; 118:106788.

Abstract
BACKGROUND Ideally all participants in a randomised controlled trial (RCT) should fully receive their allocated intervention; however, this rarely occurs in practice. Intervention adherence affects Type II error so influences the interpretation of trial results and subsequent implementation. We aimed to describe current practice in the definition, measurement, and reporting of intervention adherence in non-pharmacological RCTs, and how this data is incorporated into a trial's interpretation and conclusions. METHODS We conducted a systematic review of phase III RCTs published between January 2018 and June 2020 in the National Institute for Health Research Journals Library for the Health Technology Assessment, Programme Grants for Applied Research, and Public Health Research funding streams. RESULTS Of 237 reports published, 76 met the eligibility criteria and were included. Most RCTs (n = 68, 89.5%) reported adherence, though use of terminology varied widely; nearly three quarters of these (n = 49, 72.1%) conducted a sensitivity analysis. Adherence measures varied between intervention types: behavioural change (n = 10, 43.5%), psychological therapy (n = 5, 83.3%) and physiotherapy/rehabilitation (n = 8, 66.7%) interventions predominately measured adherence based on session attendance. Whereas medical device and surgical interventions (n = 17, 73.9%) primarily record the number of participants receiving the allocated intervention, a third (n = 33, 67.3%) of studies reported a difference in findings between primary and sensitivity analyses. CONCLUSIONS Although most trials report elements of adherence, terminology was inconsistent, and there was no systematic approach to its measurement, analyses, interpretation, or reporting. Given the importance of adherence within clinical trials, there is a pressing need for a standardised approach or framework.

Abstract
AIMS This study aims to estimate economic outcomes associated with 30-day deep surgical site infection (SSI) from closed surgical wounds in patients with lower limb fractures following major trauma. METHODS Data from the Wound Healing in Surgery for Trauma (WHiST) trial, which collected outcomes from 1,547 adult participants using self-completed questionnaires over a six-month period following major trauma, was used as the basis of this empirical investigation. Associations between deep SSI and NHS and personal social services (PSS) costs (£, 2017 to 2018 prices), and between deep SSI and quality-adjusted life years (QALYs), were estimated using descriptive and multivariable analyses. Sensitivity analyses assessed the impact of uncertainty surrounding components of the economic analyses. RESULTS Compared to participants without deep SSI, those with deep SSI had higher mean adjusted total NHS and PSS costs (adjusted mean difference £1,577 (95% confidence interval (CI) -951 to 4,105); p = 0.222), and lower mean adjusted QALYs (adjusted mean difference -0.015 (95% CI -0.032 to 0.002); p = 0.092) over six months post-injury, but this difference was not statistically significant. The results were robust to the sensitivity analyses performed. CONCLUSION This study found worse economic outcomes during the first six months post-injury in participants who experience deep SSI following orthopaedic surgery for major trauma to the lower limb. However, the increase in cost associated with deep SSI was less than previously reported in the orthopaedic trauma literature. Cite this article: Bone Jt Open 2022;3(5):398-403.

Abstract
AIMS The aim of this study was to report the outcomes of patients with severe open fractures of the lower limb in the five years after they took part in the Wound management for Open Lower Limb Fracture (WOLLF) trial. METHODS The WOLLF trial compared standard dressings to negative pressure wound therapy (NPWT) applied at the end of the first surgical wound debridement, and patients were followed-up for 12 months. At 12 months, 170 of the original 460 participants agreed to take part in this medium-term follow-up study. Patients reported their Disability Rating Index (DRI) (0 to 100, where 100 is total disability) and health-related quality of life (HRQoL) using the EuroQol five-dimension three-level health questionnaire (EQ-5D-3L) annually by self-reported questionnaire. Further surgical interventions related to the open fracture were also recorded. RESULTS There was no evidence of a difference in patient-reported disability, HRQoL, or the need for further surgery between patients treated with NPWT versus standard dressings at five years. Considering the combined results for all participants, there was a small but statistically significant change in DRI scores over time (1.6 units per year; p = 0.005), but no evidence that EQ-5D-3L scores changed significantly during years two to five (p = 0.551). CONCLUSION This study shows that the high levels of disability and reduced HRQoL reported by patients 12 months after severe open fractures of the lower limb persist in the medium term, with little evidence of improvement between years two and five.

Abstract
BACKGROUND Indications for the use of negative pressure wound therapy (NPWT) are broad and include prophylaxis for surgical site infections (SSIs). Existing evidence for the effectiveness of NPWT on postoperative wounds healing by primary closure remains uncertain. OBJECTIVES To assess the effects of NPWT for preventing SSI in wounds healing through primary closure, and to assess the cost-effectiveness of NPWT in wounds healing through primary closure. SEARCH METHODS In January 2021, we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries and references of included studies, systematic reviews and health technology reports. There were no restrictions on language, publication date or study setting. SELECTION CRITERIA We included trials if they allocated participants to treatment randomly and compared NPWT with any other type of wound dressing, or compared one type of NPWT with another. DATA COLLECTION AND ANALYSIS At least two review authors independently assessed trials using predetermined inclusion criteria. We carried out data extraction, assessment using the Cochrane risk of bias tool, and quality assessment according to Grading of Recommendations, Assessment, Development and Evaluations methodology. Our primary outcomes were SSI, mortality, and wound dehiscence. MAIN RESULTS In this fourth update, we added 18 new randomised controlled trials (RCTs) and one new economic study, resulting in a total of 62 RCTs (13,340 included participants) and six economic studies. Studies evaluated NPWT in a wide range of surgeries, including orthopaedic, obstetric, vascular and general procedures. All studies compared NPWT with standard dressings. Most studies had unclear or high risk of bias for at least one key domain. Primary outcomes Eleven studies (6384 participants) which reported mortality were pooled. There is low-certainty evidence showing there may be a reduced risk of death after surgery for people treated with NPWT (0.84%) compared with standard dressings (1.17%) but there is uncertainty around this as confidence intervals include risk of benefits and harm; risk ratio (RR) 0.78 (95% CI 0.47 to 1.30; I2 = 0%). Fifty-four studies reported SSI; 44 studies (11,403 participants) were pooled. There is moderate-certainty evidence that NPWT probably results in fewer SSIs (8.7% of participants) than treatment with standard dressings (11.75%) after surgery; RR 0.73 (95% CI 0.63 to 0.85; I2 = 29%). Thirty studies reported wound dehiscence; 23 studies (8724 participants) were pooled. There is moderate-certainty evidence that there is probably little or no difference in dehiscence between people treated with NPWT (6.62%) and those treated with standard dressing (6.97%), although there is imprecision around the estimate that includes risk of benefit and harms; RR 0.97 (95% CI 0.82 to 1.16; I2 = 4%). Evidence was downgraded for imprecision, risk of bias, or a combination of these. Secondary outcomes There is low-certainty evidence for the outcomes of reoperation and seroma; in each case, confidence intervals included both benefit and harm. There may be a reduced risk of reoperation favouring the standard dressing arm, but this was imprecise: RR 1.13 (95% CI 0.91 to 1.41; I2 = 2%; 18 trials; 6272 participants). There may be a reduced risk of seroma for people treated with NPWT but this is imprecise: the RR was 0.82 (95% CI 0.65 to 1.05; I2 = 0%; 15 trials; 5436 participants). For skin blisters, there is low-certainty evidence that people treated with NPWT may be more likely to develop skin blisters compared with those treated with standard dressing (RR 3.55; 95% CI 1.43 to 8.77; I2 = 74%; 11 trials; 5015 participants). The effect of NPWT on haematoma is uncertain (RR 0.79; 95 % CI 0.48 to 1.30; I2 = 0%; 17 trials; 5909 participants; very low-certainty evidence). There is low-certainty evidence of little to no difference in reported pain between groups. Pain was measured in different ways and most studies could not be pooled; this GRADE assessment is based on all fourteen trials reporting pain; the pooled RR for the proportion of participants who experienced pain was 1.52 (95% CI 0.20, 11.31; I2 = 34%; two studies; 632 participants). Cost-effectiveness Six economic studies, based wholly or partially on trials in our review, assessed the cost-effectiveness of NPWT compared with standard care. They considered NPWT in five indications: caesarean sections in obese women; surgery for lower limb fracture; knee/hip arthroplasty; coronary artery bypass grafts; and vascular surgery with inguinal incisions. They calculated quality-adjusted life-years or an equivalent, and produced estimates of the treatments' relative cost-effectiveness. The reporting quality was good but the evidence certainty varied from moderate to very low. There is moderate-certainty evidence that NPWT in surgery for lower limb fracture was not cost-effective at any threshold of willingness-to-pay and that NPWT is probably cost-effective in obese women undergoing caesarean section. Other studies found low or very low-certainty evidence indicating that NPWT may be cost-effective for the indications assessed. AUTHORS' CONCLUSIONS People with primary closure of their surgical wound and treated prophylactically with NPWT following surgery probably experience fewer SSIs than people treated with standard dressings but there is probably no difference in wound dehiscence (moderate-certainty evidence). There may be a reduced risk of death after surgery for people treated with NPWT compared with standard dressings but there is uncertainty around this as confidence intervals include risk of benefit and harm (low-certainty evidence). People treated with NPWT may experience more instances of skin blistering compared with standard dressing treatment (low-certainty evidence). There are no clear differences in other secondary outcomes where most evidence is low or very low-certainty. Assessments of cost-effectiveness of NPWT produced differing results in different indications. There is a large number of ongoing studies, the results of which may change the findings of this review. Decisions about use of NPWT should take into account surgical indication and setting and consider evidence for all outcomes.

Abstract
Agricultural work involves ergonomic and psychosocial strain, which contribute to musculoskeletal conditions. The aim of this study was to assess if specific ergonomic, psychosocial, and preventive factors are linked to musculoskeletal pain or discomfort symptoms (MSS) in farmers and ranchers. We analyzed data from the Central States Center for Agricultural Safety and Health survey that was conducted in 2018 in a seven-state region of the central United States. MSS were assessed with questions from the Standardized Nordic Questionnaire. The survey included questions on demographic, ergonomic, psychosocial and preventive factors. Farm production variables were added from the Farm Market iD database. We analyzed the data using Generalized Estimating Equations. The overall prevalence of MSS for all body sites combined was 59% among 4,354 farmers and ranchers who responded (19% response rate). After controlling for age, sex, and operator status, three factors (high stress level, sleep deprivation, and exhaustion/fatigue) showed the strongest associations with MSS in any body site, with adjusted odds ratios (OR) ranging from 4.8 to 5.6. Forceful exertions, repetitive tasks, awkward postures, frequent manual labor, and vibration were also significantly associated with MSS, with adjusted ORs ranging from 1.8 to 3.3. Recommended preventive techniques were not protective for MSS. New effective strategies are needed to reduce the high burden of musculoskeletal outcomes among farmers and agricultural workers.

Abstract
AIMS The aim of this study was to investigate the relationship between the Orthopaedic Trauma Society (OTS) classification of open fractures and economic costs. METHODS Resource use was measured during the six months that followed open fractures of the lower limb in 748 adults recruited as part of two large clinical trials within the UK Major Trauma Research Network. Resource inputs were valued using unit costs drawn from primary and secondary sources. Economic costs (GBP sterling, 2017 to 2018 prices), estimated from both a NHS and Personal Social Services (PSS) perspective, were related to the degree of complexity of the open fracture based on the OTS classification. RESULTS Adjusted mean total NHS and PSS costs were £13,785 following treatment of complex fractures and £3,550 following treatment of simple fractures, where the open fracture wound is closed at the end of the first wound debridement, generating a mean difference of £10,235 (95% confidence interval £8,074 to £12,396). CONCLUSION Following previous work correlating clinical outcomes with the OTS classification of open fractures, this study suggests that the new OTS classification also correlates with economic costs estimated from alternative study perspectives.

Abstract
BACKGROUND Open tibial fracture research has traditionally focused on surgical techniques; however, despite technological advances, outcomes from these injuries remain poor, with patients facing a sustained reduced quality of life. Research has rarely asked patients what is important to them after an open tibial fracture, and this question could potentially offer great insight into how to support patients. A qualitative study may assist in our understanding of this subject. QUESTIONS/PURPOSES We asked: (1) What common themes did patients who have experienced open tibial fractures share? (2) What stresses and coping strategies did those patients articulate? (3) What sources for acquiring coping strategies did patients say they benefited from? METHODS Semistructured interviews were conducted with patients who had sustained an open tibial fracture between January 1, 2016 and January 1, 2019. All participants were recruited from a Level 1 trauma center in England, and 26 participants were included. The mean age was 44 ± 17 years, and 77% (20 of 26) were men. The patients' injuries ranged in severity, and they had a range of treatments and complications. Transcripts were analyzed using framework analysis, with codes subsequently organized into themes and subthemes. RESULTS Four themes were identified, which included recouping physical mobility, values around treatment, fears about poor recovery, and coping strategies to reduce psychological burden. Coping strategies were important in mitigating the psychological burden of injury. Task-focused coping strategies were preferred by patients and perceived as taking a proactive approach to recovery. Healthcare practitioners, and others with lived experience were able to educate patients on coping, but such resources were scant and therefore probably less accessible to those with the greatest need. CONCLUSION Most individuals fail to return to previous activities, and it is unlikely that improvements in surgical techniques will make major improvements in patient outcomes in the near future. Investment in psychosocial support could potentially improve patient experience and outcomes. Digital information platforms and group rehabilitation clinics were identified as potential avenues for development that could offer individuals better psychosocial support with minimal additional burden for surgeons. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
Though infection is a common and costly complication following fracture, there is a scarcity of literature focused on the additional cost of healthcare when a fracture becomes infected. This literature review compiles existing heterogenous data to evaluate the cost of infected fractures, yielding an estimate of a 1.2-fold to six-fold increase in healthcare costs associated with infection. The increases in cost were largely driven by an increased length of stay. Factors which affect this increase include the infectious agent, the depth of infection and the location of the fracture. In order to reduce healthcare costs, early soft tissue cover and prophylactic antibiotics are effective in that they reduce the infection rates. An alternative approach is to reduce the length of stay, the key driver of cost, for example by reducing the length of inpatient antibiotic therapy. Further cost-utility analyses which focus on the same aspects of the healthcare costs are required for a more accurate estimation of the cost.

Abstract
AIMS Deep surgical site infection (SSI) is common after lower limb fracture. We compared the diagnosis of deep SSI using alternative methods of data collection and examined the agreement of clinical photography and in-person clinical assessment by the Centers for Disease Control and Prevention (CDC) criteria after lower limb fracture surgery. METHODS Data from two large, UK-based multicentre randomized controlled major trauma trials investigating SSI and wound healing after surgical repair of open lower limb fractures that could not be primarily closed (UK WOLLF), and surgical incisions for fractures that were primarily closed (UK WHiST), were examined. Trial interventions were standard wound care management and negative pressure wound therapy after initial surgical debridement. Wound outcomes were collected from 30 days to six weeks. We compared the level of agreement between wound photography and clinical assessment of CDC-defined SSI. We are also assessed the level of agreement between blinded independent assessors of the photographs. RESULTS Rates of CDC-defined deep SSI were 7.6% (35/460) after open fracture and 6.3% (95/1519) after closed incisional repair. Photographs were obtained for 77% and 73% of WOLLF and WHiST cohorts respectively (all participants n = 1,478). Agreement between photographic-SSI and CDC-SSI was fair for open fracture wounds (83%; k = 0.27 (95% confidence interval (CI) 0.14 to 0.42)) and for closed incisional wounds (88%; k = 0.29 (95% CI 0.20 to 0.37)) although the rate of photographically detected deep SSIs was twice as high as CDC-SSI (12% vs 6%). Agreement between different assessors for photographic-SSI (WOLLF 88%, k = 0.63 (95% CI 0.52 to 0.72); WHiST 89%; k = 0.61 (95% CI 0.54 to 0.69)); and wound healing was good (WOLLF 90%; k = 0.80 (95% CI 0.73 to 0.86); WHiST 87%; k = 0.57 (95% CI 0.50 to 0.64)). CONCLUSION Although wound photography was feasible within the research context and inter-rater assessor agreement substantial, digital photographs used in isolation overestimated deep SSI rates, when compared to CDC criteria. Wound photography should not replace clinical assessment in pragmatic trials but may be useful for screening purposes where surgical infection outcomes are paramount.

Rates and timing of short-term complications following operative treatment of tibial shaft fractures. OTA Int 2021; 4:e158. [PMID: 34765906 PMCID: PMC8575429 DOI: 10.1097/oi9.0000000000000158] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2021] [Accepted: 10/04/2021] [Indexed: 10/31/2022]
Abstract
Introduction Tibial shaft fractures are a relatively common injury in orthopaedic surgery, with management options including intramedullary nail (IMN) fixation or open reduction internal fixation (ORIF) with plate osteosynthesis. Using a large national database, we sought to compare the prevalence and timing of short-term complications following either IMN or ORIF for tibial shaft fractures. Methods The American College of Surgeons National Surgical Quality Improvement Program was used to identify patients undergoing IMN or ORIF for the treatment of tibial shaft fracture between 2012 and 2018. Multivariate Poisson hurdle regression models were utilized to determine predictors of postoperative complications as well as the timing of postoperative complications. Results A total of 4963 tibial shaft fracture were identified, with 3601 patients undergoing IMN (72.6%) and 1362 undergoing ORIF (27.4%). Patients undergoing IMN had a lower mean age of 48.8 compared with 53.9 for plate osteosynthesis (P < .001). IMN patients were also more likely to be male (53.5%) compared with ORIF patients (44.2%, P < .001). In multivariate analysis, ORIF patients were significantly more likely to experience surgical site complications, including dehiscence, superficial, and deep infections (OR 2.04, P = .003). There was no difference in probability of VTE between constructs; however, patients who underwent ORIF were diagnosed with VTE earlier than those who underwent IMN (relative rate 0.50, P < .001). There was no difference between ORIF and IMN with regard to probability or timing of subsequent blood transfusion, major complications, or return to the operating room. Many patient factors, such as higher American Society of Anesthesiologists score, congestive heart failure, and hypertension, were independently associated with an increased risk of postoperative complications. Conclusions Postoperative complications within 30 days are common after the surgical treatment of tibial shaft fractures. The risk of developing specific complications and the timing of these complications vary depending on numerous factors, including potentially modifiable risk factors such as the method of fixation or operative time, as well as nonmodifiable risk factors such as medical comorbidities.

Abstract
INTRODUCTION Fracture-related infection (FRI) is a severe musculoskeletal complication in orthopedic trauma surgery, causing challenges in bony and soft tissue management. Currently, negative-pressure wound therapy (NPWT) is often used as temporary coverage for traumatic and surgical wounds, also in cases of FRI. However, controversy exists about the impact of NPWT on the outcome in FRI, specifically on infection recurrence. Therefore, this systematic review qualitatively assesses the literature on the role of NPWT in the management of FRI. METHODS A literature search of the PubMed, Embase, and Web of Science database was performed. Studies that reported on infection recurrence related to FRI management combined with NPWT were eligible for inclusion. Quality assessment was done using the PRISMA statement and the Newcastle-Ottawa Quality Assessment Scale. RESULTS After screening and quality assessment of 775 unique identified records, eight articles could be included for qualitative synthesis. All eight studies reported on infection recurrence, which ranged from 2.8% to 34.9%. Six studies described wound healing time, varying from two to seven weeks. Four studies took repeated microbial swabs during subsequent vacuum dressing changes. One study reported newly detected pathogens in 23% of the included patients, and three studies did not find new pathogens. CONCLUSION This review provides an assessment of current literature on the role of NPWT in the management of soft tissue defects in patients with FRI. Due to the lack of uniformity in included studies, conclusions should be drawn with caution. Currently, there is no clear scientific evidence to support the use of NPWT as definitive treatment in FRI. At this stage, we can only recommend early soft tissue coverage (within days) with a local or free flap. NPWT may be safe for a few days as temporarily soft tissue coverage until definitive soft tissue management could be performed. However, comparative studies between NPWT and early wound closure in FRI patients are needed.

Abstract
Negative pressure wound therapy (NPWT) has been recognized as an effective method for the treatment of intractable wounds. However, its effects on bone healing remain to be elucidated. Our previous study demonstrated that NPWT induced cell proliferation and osteoblastic differentiation of rat periosteum-derived mesenchymal stem cells (P-MSCs). It was reported that following NPWT treatment, the expression of the mechanotransduction molecule integrin β5 is increased, indicating that NPWT may serve an active role in fracture healing by enhancing bone formation and reducing bone resorption. The present study sought to further investigate the efficacy of NPWT on the bone regeneration process in a rabbit radial gap-healing model. All rabbits with radial defects were randomly divided into two groups: NPWT and control groups. Continuous negative pressure at -125 mmHg was applied to all rabbits. Furthermore, X-ray imaging and scoring on day 7, 14, 21 and 28 postoperatively were performed to evaluate new bone formation. Histological changes were determined via hematoxylin and eosin and Masson's trichrome staining at 2- and 4-weeks following surgery. In addition, vimentin-positive cells located in the periosteum were detected via immunohistochemical examination on day 3 post operation. Finally, protein expression levels of vascular endothelial growth factor (VEGF), bone morphogenetic protein (BMP)-2 and osteopontin (OPN) were evaluated using western blot analysis on the 2nd and 4th week following NPWT. X-ray and histological examination revealed that the bone-healing processes in the NPWT group were faster compared with the control group. Additionally, compared with the control group, the NPWT group exhibited higher X-ray scores, increased percentage of positive vimentin-stained cells and upregulated expression of VEGF, BMP-2 and OPN proteins. The aforementioned findings suggest that NPWT, under a continuous negative pressure of -125 mmHg, may accelerate bone regeneration by enhancing MSC proliferation, osteoblastic differentiation and VEGF, BMP-2 and OPN expression.

Abstract
PURPOSE The purpose of this study was to clinically compare the single-incision and dual-incision approaches for the treatment of distal tibial and fibular fractures. METHODS In total, 93 patients were enrolled, and the mean follow-up was 15 months (range 12-19 months). The patients treated for open reduction and internal fixation were randomly classified into two groups based on the approach used: 45 patients were treated using the single-incision approach (group 1) and 48 patients were treated using the dual-incision approach (group 2). In these two groups, operation time, discharge time, postoperative complications, and ankle function evaluations (Olerud-Molander Ankle Score) were compared between the two groups. RESULTS There were no significant differences in the mean operation time (98.2 ± 18.5 vs. 103.6 ± 19.3), discharge time (11.1 ± 3.9 vs. 12.5 ± 5.7), overall surgical complication rates (9/45 vs. 15/48), or ankle function between the two groups (p > 0.05). However, the rate of soft tissue-related complications, such as skin slough, infection, nonunion, and delayed union, was significantly lower in group 1 (5/45) than in group 2 (14/48) (p < 0.05). CONCLUSION The two incision approaches were found to have similar clinical outcomes. However, with regard to soft tissue conservation, the single-incision approach was superior to the dual-incision and maybe a reliable alternative.

Abstract
As the biologically friendly and biomechanically sound technique of intramedullary fixation has been increasingly applied to distal tibia diaphyseal fractures, challenges with the technique have emerged. Malalignment, most often valgus and recurvatum, is more common than with mid-diaphyseal patterns, given the lack of endosteal fit, and this can be challenging to prevent. Key technical steps can ensure success. These include recognition and initial fixation of intra-articular fracture planes, the use of percutaneous clamps, a slightly lateral terminal nail position, and the use of blocking wires or screws to prevent malalignment after nail passage. With thorough preoperative planning and early recognition of troublesome patterns, a variety of techniques can be applied to obtain and maintain a stable reduction throughout the procedure.

Abstract
This meta-analysis was conducted to identify the potential benefits and the efficacy of negative-pressure wound therapy (NPWT) for III/IV pressure injuries (PIs) compared with standard wound care (SWC). Sixteen RCTs with 629 patients were included in our analysis. The methodological quality was assessed by the Cochrane Collaboration Tool. The outcomes included complete ulcer healing rate, wound healing time, pain score, the frequency of dressing change, hospitalization cost, the condition of the exudate, and the wound improvement. The percentage of healing rate was 61.45% for the NPWT group and 36.90% for SWC (95% CI: 1.32-1.70). There were significant differences in wound healing time (WMD = -16.47 days, 95% [CI (-22.36, - 10.59) days, P ≤ .001]). The pain score and hospitalization cost in NPWT was lower compared with SWC group (WMD = -2.39, 95% CI [-3.47, -1.30], P ≤ .001); (SMD = -2.55, 95% CI [-4.07, -1.03], P < .01). The frequency of dressing change in both NPWT groups was greatly reduced (SMD = -3.61, 95% [CI (-4.57, - 2.66) times, P ≤ .001]). Our meta-analysis indicated that NPWT was associated with greater improvements in improving PIs and shorting healing time for III/IV PIs. However, this conclusion needs to be confirmed by high-quality multicenter RCTs.

Abstract
Introduction We hypothesize that Negative Pressure Wound Therapy (NPWT) is associated with a lower incidence of surgical site infection (SSI) in lower extremity amputations (LEAs), a potentially devastating complication. Methods NSQIP database from 2011 to 2018 was queried to identify all-level LEAs. Cases using NPWT were identified. One-to-one nearest-neighbor propensity score matching was performed using a binary logistic regression on NPWT status controlling for patient comorbidities. Results NPWT was used in 133 of 5237 total LEAs (2.54%). Compared to propensity score-matched controls, they had significantly fewer SSIs (1.50% vs. 8.27%). Conclusions NPWT was associated with lower incidence of SSI.

Abstract
BACKGROUND Major trauma is the leading cause of death in people aged < 45 years. Patients with major trauma usually have lower-limb fractures. Surgery to fix the fractures is complicated and the risk of infection may be as high as 27%. The type of dressing applied after surgery could potentially reduce the risk of infection. OBJECTIVES To assess the deep surgical site infection rate, disability, quality of life, patient assessment of the surgical scar and resource use in patients with surgical incisions associated with fractures following major trauma to the lower limbs treated with incisional negative-pressure wound therapy versus standard dressings. DESIGN A pragmatic, multicentre, randomised controlled trial. SETTING Twenty-four specialist trauma hospitals representing the UK Major Trauma Network. PARTICIPANTS A total of 1548 adult patients were randomised from September 2016 to April 2018. Exclusion criteria included presentation > 72 hours after injury and inability to complete questionnaires. INTERVENTIONS Incisional negative-pressure wound therapy (n = 785), in which a non-adherent absorbent dressing covered with a semipermeable membrane is connected to a pump to create a partial vacuum over the wound, versus standard dressings not involving negative pressure (n = 763). Trial participants and the treating surgeon could not be blinded to treatment allocation. MAIN OUTCOME MEASURES Deep surgical site infection at 30 days was the primary outcome measure. Secondary outcomes were deep infection at 90 days, the results of the Disability Rating Index, health-related quality of life, the results of the Patient and Observer Scar Assessment Scale and resource use collected at 3 and 6 months post surgery. RESULTS A total of 98% of participants provided primary outcome data. There was no evidence of a difference in the rate of deep surgical site infection at 30 days. The infection rate was 6.7% (50/749) in the standard dressing group and 5.8% (45/770) in the incisional negative-pressure wound therapy group (intention-to-treat odds ratio 0.87; 95% confidence interval 0.57 to 1.33; p = 0.52). There was no difference in the deep surgical site infection rate at 90 days: 13.2% in the standard dressing group and 11.4% in the incisional negative-pressure wound therapy group (odds ratio 0.84, 95% confidence interval 0.59 to 1.19; p = 0.32). There was no difference between the two groups in disability, quality of life or scar appearance at 3 or 6 months. Incisional negative-pressure wound therapy did not reduce the cost of treatment and was associated with a low probability of cost-effectiveness. LIMITATIONS Owing to the emergency nature of the surgery, we anticipated that some patients who were randomised would subsequently be unable or unwilling to participate. However, the majority of the patients (85%) agreed to participate. Therefore, participants were representative of the population with lower-limb fractures associated with major trauma. CONCLUSIONS The findings of this study do not support the use of negative-pressure wound therapy in patients having surgery for major trauma to the lower limbs. FUTURE WORK Our work suggests that the use of incisional negative-pressure wound therapy dressings in other at-risk surgical wounds requires further investigation. Future research may also investigate different approaches to reduce postoperative infections, for example the use of topical antibiotic preparations in surgical wounds and the role of orthopaedic implants with antimicrobial coatings when fixing the associated fracture.

Abstract
BACKGROUND Indications for the use of negative pressure wound therapy (NPWT) are broad and include prophylaxis for surgical site infections (SSIs). Existing evidence for the effectiveness of NPWT on postoperative wounds healing by primary closure remains uncertain. OBJECTIVES To assess the effects of NPWT for preventing SSI in wounds healing through primary closure, and to assess the cost-effectiveness of NPWT in wounds healing through primary closure. SEARCH METHODS In June 2019, we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries and references of included studies, systematic reviews and health technology reports. There were no restrictions on language, publication date or study setting. SELECTION CRITERIA We included trials if they allocated participants to treatment randomly and compared NPWT with any other type of wound dressing, or compared one type of NPWT with another type of NPWT. DATA COLLECTION AND ANALYSIS At least two review authors independently assessed trials using predetermined inclusion criteria. We carried out data extraction, assessment using the Cochrane 'Risk of bias' tool, and quality assessment according to Grading of Recommendations, Assessment, Development and Evaluations methodology. MAIN RESULTS In this third update, we added 15 new randomised controlled trials (RCTs) and three new economic studies, resulting in a total of 44 RCTs (7447 included participants) and five economic studies. Studies evaluated NPWT in the context of a wide range of surgeries including orthopaedic, obstetric, vascular and general procedures. Economic studies assessed NPWT in orthopaedic, obstetric and general surgical settings. All studies compared NPWT with standard dressings. Most studies had unclear or high risk of bias for at least one key domain. Primary outcomes Four studies (2107 participants) reported mortality. There is low-certainty evidence (downgraded twice for imprecision) showing no clear difference in the risk of death after surgery for people treated with NPWT (2.3%) compared with standard dressings (2.7%) (risk ratio (RR) 0.86; 95% confidence interval (CI) 0.50 to 1.47; I2 = 0%). Thirty-nine studies reported SSI; 31 of these (6204 participants), were included in meta-analysis. There is moderate-certainty evidence (downgraded once for risk of bias) that NPWT probably results in fewer SSI (8.8% of participants) than treatment with standard dressings (13.0% of participants) after surgery; RR 0.66 (95% CI 0.55 to 0.80 ; I2 = 23%). Eighteen studies reported dehiscence; 14 of these (3809 participants) were included in meta-analysis. There is low-certainty evidence (downgraded once for risk of bias and once for imprecision) showing no clear difference in the risk of dehiscence after surgery for NPWT (5.3% of participants) compared with standard dressings (6.2% of participants) (RR 0.88, 95% CI 0.69 to 1.13; I2 = 0%). Secondary outcomes There is low-certainty evidence showing no clear difference between NPWT and standard treatment for the outcomes of reoperation and incidence of seroma. For reoperation, the RR was 1.04 (95% CI 0.78 to 1.41; I2 = 13%; 12 trials; 3523 participants); for seroma, the RR was 0.72 (95% CI 0.50 to 1.05; I2 = 0%; seven trials; 729 participants). The effect of NPWT on occurrence of haematoma or skin blisters is uncertain (very low-certainty evidence); for haematoma, the RR was 0.67 (95% CI 0.28 to 1.59; I2 = 0%; nine trials; 1202 participants) and for blisters the RR was 2.64 (95% CI 0.65 to 10.68; I2 = 69%; seven trials; 796 participants). The overall effect of NPWT on pain is uncertain (very low-certainty evidence from seven trials (2218 participants) which reported disparate measures of pain); but moderate-certainty evidence suggests there is probably little difference between the groups in pain after three or six months following surgery for lower limb fracture (one trial, 1549 participants). There is also moderate-certainty evidence for women undergoing caesarean sections (one trial, 876 participants) and people having surgery for lower limb fractures (one trial, 1549 participants) that there is probably little difference in quality of life scores at 30 days or 3 or 6 months, respectively. Cost-effectiveness Five economic studies, based wholly or partially on trials included in our review, assessed the cost-effectiveness of NPWT compared with standard care. They considered NPWT in four indications: caesarean sections in obese women; surgery for lower limb fracture; knee/hip arthroplasty and coronary artery bypass graft surgery. They calculated quality-adjusted life-years for treatment groups and produced estimates of the treatments' relative cost-effectiveness. The reporting quality was good but the grade of the evidence varied from moderate to very low. There is moderate-certainty evidence that NPWT in surgery for lower limb fracture was not cost-effective at any threshold of willingness-to-pay and that NPWT is probably cost-effective in obese women undergoing caesarean section. Other studies found low or very low-certainty evidence indicating that NPWT may be cost-effective for the indications assessed. AUTHORS' CONCLUSIONS People experiencing primary wound closure of their surgical wound and treated prophylactically with NPWT following surgery probably experience fewer SSI than people treated with standard dressings (moderate-certainty evidence). There is no clear difference in number of deaths or wound dehiscence between people treated with NPWT and standard dressings (low-certainty evidence). There are also no clear differences in secondary outcomes where all evidence was low or very low-certainty. In caesarean section in obese women and surgery for lower limb fracture, there is probably little difference in quality of life scores (moderate-certainty evidence). Most evidence on pain is very low-certainty, but there is probably no difference in pain between NPWT and standard dressings after surgery for lower limb fracture (moderate-certainty evidence). Assessments of cost-effectiveness of NPWT produced differing results in different indications. There is a large number of ongoing studies, the results of which may change the findings of this review. Decisions about use of NPWT should take into account surgical indication and setting and consider evidence for all outcomes.

Abstract
To evaluate the application, safety and efficacy of the patients treated with intramedullary nailing (IMN) and minimally invasive plate osteosynthesis (MIPO) in distal tibia fractures. Following the Preferred Reporting Items for Systematic Reviews and Meta Analysis (PRISMA) guidelines, we searched databases PubMed, Cochrane library, EMBASE and Web of Science from inception of the database up to 10 October 2018, using the keywords "distal tibia fractures", "plate", "intramedullary nailing" and "RCT" to identify randomized clinical trials about distal tibia fractures. The included studies were assessed by two researchers according to the Cochrane risk-of-bias criteria. The primary outcome of measurement included operation time, malunion rate, nonunion/delayed union rate, and wound complication. Data analysis was conducted with Review Manager 5.3 software. A total of 10 RCTs involving 911 patients fulfilled the inclusion criteria with 455 patients in the IMN group and 456 patients in the MIPO group. There were no significant differences in radiation time, nonunion or delayed union rate, union time and operation time between the two groups. Patients treated with MIPO had lower incidence of malunion compared with IMN (RR = 1.85, 95%CI: 1.21 to 2.83, P = 1.00), while IMN seemed to have lower surgical incision complications whether in closed or opening fractures (RR = 0.49, 95%CI 0.33 to 0.73, P = 0.43). But in patients classified as 43A, the result of subgroup analysis suggested that there was no significant inwound complication between the two groups. MIPO was superior in preventing malunion compared with IMN, and intramedullary nailing appeared to have lower wound complications. However, in patients with 43A distal tibial fractures, MIPO was more recommended for its prevention of malunion. No matter which method we choose, we should notice and prevent the associated complications.

Abstract
OBJECTIVES To compare the efficacy of negative pressure wound therapy (NPWT) versus conventional dressings (CD) in the management of open fractures. DATA SOURCES A systematic search of English articles in the PubMed/MEDLINE, Embase, and the Cochrane Library through April 2019 comparing NPWT versus CD in the management of open fractures. STUDY SELECTION Inclusion criteria were articles in English language, comparing NPWT with CD in skeletally mature individuals who had sustained an open fracture at any anatomical site, reporting on rates of deep infection, flap frequency, flap failure, nonunion, amputation, length of hospital, or intensive care unit stay. DATA EXTRACTION Two authors independently extracted data from selected studies, and the data collected were compared with verify agreement. DATA SYNTHESIS Pooled odds ratios were calculated for dichotomous outcomes, whereas continuous data were analyzed using the standard weighted mean difference. A random or fixed effect model was used depending on the level of heterogeneity between the studies. CONCLUSIONS NPWT results in decreased likelihood of deep infection and flap failure compared with CD in the management of open fractures not directly amenable to early closure. LEVEL OF EVIDENCE Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

Abstract
INTRODUCTION Severe open tibial fractures are limb-threatening injuries. Outcomes depend on a complex interplay of patient, injury and treatment factors. 2009 guidelines from the British Orthopaedic Association (BOA) and British Association of Plastic, Reconstructive and Aesthetic Surgeons (BAPRAS) recommend prophylactic intravenous antibiotic administration within three hours of injury. More recent National Institute for Health and Care Excellence (NICE) 2016 guidelines recommend pre-hospital antibiotic administration where possible. This study aimed to analyse the impact of time to antibiotics on development of deep infection. METHODS Adult acute Gustilo-Anderson 3B open tibial fractures managed at a single UK Major Trauma Centre were reviewed retrospectively over a three-year period, including a period before and after the regional ambulance service introduced a policy of administering pre-hospital intravenous antibiotics to open fractures in 2016. Development of deep infection was recorded as the primary outcome measure. Complete case regression analysis was performed. Time was assessed as a continuous variable and as thresholds with antibiotics received within one or three hours of injury. RESULTS 156 patients with 159 fractures were included. Following introduction of new guidance in 2016, median time to antibiotics decreased from 180 to 160 min and more patients received pre-hospital antibiotics (2% vs. 33%). Overall, 7.5% developed deep infection (n = 12) within a median follow-up of 26 months. Logistic regression found no relationship between any independent variable, including time to antibiotic administration, and development of deep infection. CONCLUSIONS There are a variety of factors identified in the literature and in national policies and treatment guidelines as potentially modifiable to reduce the risk of deep infection following open fractures. In this study, time to antibiotic administration was not associated with the risk of developing deep infection. The results of this study demonstrate a low infection rate, which may be due to expedient expert care delivered by a dedicated orthoplastic service in line with national guidance where achievable.

Abstract
The treatment of very distal tibial (pilon) fractures remains one of the great challenges for the orthopaedic traumatologist. It is essential that the treating surgeon have a proper understanding of the fracture, the soft tissue injury, and the skills to deal with these often-complicated injuries to minimize the risk of complications that can occur after these often higher energy injuries. Bone stability can be achieved with both circular ring fixation and plating, and both can yield good results in experienced hands. This debate considers the advantages and disadvantages of each technique.

Abstract
OBJECTIVES Treatment of open fractures is complex and patients may require muscle and skin grafts. The aim of this study was to gain a greater understanding of patient experience of recovery from open fracture of the lower limb 2-4 years postinjury. DESIGN A phenomenological approach was used to guide the design of the study. Interviews took place between October 2016 and April 2017 in the participants' own homes or via telephone. SETTING England, UK. PARTICIPANTS A purposive sample of 25 patients were interviewed with an age range of 26-80 years (median 51), 19 were male and six female, and time since injury was 24-49 months (median 35 months). RESULTS The findings identified a focus on struggling to recover as participants created a new way of living, balancing moving forward with accepting how they are, while being uncertain of the future and experiencing cycles of progress and setbacks. This was expressed through three themes: (i) 'being disempowered' with the emotional impact of dependency and uncertainty, (ii) 'being changed' and living with being fragile and being unable to move freely and (iii) 'being myself' with a loss of self, feeling and looking different, alongside recreation of self in which they integrated the past, present and future to find meaningful ways of being themselves. CONCLUSION This study identified the long-term disruption caused by serious injury, the hidden work of integration that is required in order to move forward and maximise potential for recovery. Supportive strategies that help people to self-manage their everyday emotional and physical experience of recovery from injury are required. Research should focus on developing and testing effective interventions that provide support and self-management within a holistic rehabilitation plan.

A pilot feasibility randomised clinical trial comparing dialkylcarbamoylchloride-coated dressings versus standard care for the primary prevention of surgical site infection. Int Wound J 2019; 16:883-890. [PMID: 30868734 PMCID: PMC6850133 DOI: 10.1111/iwj.13113] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2019] [Revised: 02/22/2019] [Accepted: 02/25/2019] [Indexed: 12/17/2022] Open
Abstract
A surgical site infection (SSI) may occur in up to 30% of procedures and results in significant morbidity and mortality. We aimed to assess the feasibility of conducting a randomised controlled trial (RCT) examining the use of dialkylcarbamoylchloride (DACC)-impregnated dressings, which bind bacteria at the wound bed, in the prevention of SSI in primarily closed incisional wounds. This pilot RCT recruited patients undergoing clean or clean-contaminated vascular surgery. Participants were randomised intraoperatively on a 1:1 basis to either a DACC-coated dressing or a control dressing. Outcomes were divided into feasibility and clinical outcomes. The primary clinical outcome was SSI at 30 days (assessed using Centers for Disease Control criteria and Additional treatment, Serous discharge, Erythema, Purulent exudate, Separation of the deep tissues, Isolation of bacteria and duration of inpatient Stay scoring methods). This study recruited 144 patients in 12 months at a median rate of 10 per month. Eligibility was 73% and recruitment 60%. At 30 days, there was a 36.9% relative risk reduction in the DACC-coated arm (16.22% versus 25.71%, odds ratio 0.559, P = 0.161). The number needed to treat was 11 patients. A large-scale RCT is both achievable and desirable given the relative risk reduction shown in this study. Further work is needed to improve the study protocol and involve more centres in a full-scale RCT.

Abstract
The simultaneous exposure of tissue and bone poses specific management challenges. Patients with extended soft tissue damage and high-grade compound fractures present a demanding clinical challenge, requiring a complex approach and multiple orthopaedic, plastic, and vascular-reconstructive procedures. Management involves combinations of wound debridement and closure by secondary intention, use of vacuum-assisted closure (VAC) devices, and various reconstructive plastic surgery methods. We present three consecutive complicated cases, involving compound fractures of the lower limb with massive soft tissue damage (Gustilo-Anderson type IIIB) that were managed with debridement, application of external fixation and VAC device. The mean wound size was 24 cm in length and 12 cm in width. The aim of treatment was to cover the bone with soft tissue and achieve healing of the fracture without persistent infection. Wound healing was achieved in all three cases within 30-42 days (mean 34). In one case, the skin graft was applied on day 33. Utilizing this method as part of a multi-directional approach, the VAC system helps the patient recover faster. Moreover, it acts as a feasible and valuable method to treat compound fractures with massive soft-tissue defects. VAC can replace microsurgical soft-tissue transfer, reduce the risk of infection and allow salvaging the limb.

Abstract
OBJECTIVES This feasibility study and process evaluation assessed the likely success of a definitive trial of intramedullary fixation with locked retrograde nails versus extramedullary fixation with fixed angle plates for fractures of the distal femur. DESIGN & SETTING A multicentre, parallel, two-arm, randomised controlled feasibility study with an embedded process evaluation was conducted at seven NHS hospitals in England. Treatment was randomly allocated in 1:1 ratio, stratified by centre and chronic cognitive impairment. Participants, but not surgeons or research staff, were blinded to the allocation. PARTICIPANTS Patients 18 years and older with a fracture of the distal femur, who their surgeon believed would benefit from internal fixation, were eligible to take part.Participants were allocated to receive either a retrograde intramedullary nail or an anatomical locking plate. OUTCOMES The primary outcomes for this feasibility study were the recruitment rate and completion rate of the EQ-5D-5L at 4 months post-randomisation. Baseline characteristics, disability rating index, quality of life scores, measurements of social support and self-efficacy, resource use and radiographic assessments were also collected. The views of patients and staff were collected during interviews. RESULTS Recruitment and data completion were lower than expected. 23 of 82 eligible patients were recruited (nail, 11; plate, 12). The recruitment rate was estimated as 0.42 (95% CI 0.27 to 0.62) participants per centre-month. Data completeness of the EQ-5D-5L at 4 months was 61 per cent (95% CI 43% to 83%). The process evaluation demonstrated that the main barriers to recruitment were variation in treatment pathways across centres, lack of surgeon equipoise and confidence in using both interventions and newly formed research cultures that lacked cohesion. CONCLUSIONS A modified trial design, with embedded recruitment support intervention, comparing functional outcome in cognitively intact adults who have sustained a fragility fracture of the distal femur is feasible. ETHICS APPROVAL The Wales Research Ethics Committee 5 approved the study (ref: 16/WA/0225). TRIAL REGISTRATION NUMBER ISRCTN92089567; Pre-results.
