Abstract
INTRODUCTION Clinical practice should be informed by high quality evidence, of which randomised controlled trials (RCTs) are considered the gold standard. Surgical trials are inherently difficult with potential problems around clinical equipoise and participant acceptability. This is often most true with trial designs comparing operative and non-operative treatments. It is hoped that research activity can be maximised by collaborating in (a) the identification of research questions and (b) involvement in clinical trials. Development of the national research networks can be utilised to provide support for research endeavours within the orthopaedic trauma community. AIMS To identify and prioritise the research questions felt to be of most importance by the orthopaedic trauma community. Research studies will be considered for questions given the highest priority. METHODS A Delphi approach was used to determine consensus between the faculty members of the AOUK. A two round process was used to elicit the research questions and then to rank them in order of priority. RESULTS 217 members of the AOUK Long Bone Faculty were asked to submit research questions, predominantly consultant orthopaedic surgeons. A 22% response rate generated 147 questions. These were collated and the most frequent 24 sent back out for ranking by mean scores. A 55% response to this second round identified 10 top questions. Literature searches for these 10 looked at current knowledge of the subject, completed and ongoing research projects. We also looked at the advantages and disadvantages of undertaking a study and the most appropriate methodology. CONCLUSION The response rates demonstrated a clear interest in developing a collaborative research strategy. This can be enhanced by utilising the support of the National Institute of Health Research Clinical Research Networks (NIHR CRN).

Abstract
Lisfranc fracture dislocations are complex lesions which, when combined with additional trauma of the ankle and foot region, create a difficult to treat injury pattern. This article presents a case of a patient with Lisfranc fracture dislocation combined with metatarsophalangeal dislocation of the second toe and ankle fracture-dislocation. The sequence of medical acts and complications included: reduction of dislocations, cast immobilization, compartment syndrome and fasciotomies, external fixator application, fasciotomies closure, and final internal fixations. The following examinations were performed: radiography, computed tomography (CT), and intracompartmental pressure measurement. Despite the compartment syndrome incidence, which was effectively managed, the patient regained an ankle- and foot-pain-free full range of motion. Although this is an isolated case of a rare injury, several recommendations can be made. Early CT scan should be used for injuries of the Lisfranc joints to fully assess the distorted anatomy of the midfoot and forefoot, which is essential for preoperative planning, medicolegal issues, and prognosis of the injury. The use of a spanning external fixator, especially in complex injuries as the one described, should be preferred to cast immobilization and should be performed as a priority surgical procedure early on in the patient's admission. The development of compartment syndrome should be monitored and intracompartmental pressures measured especially in unconscious patients. There should be a high degree of suspicion for early complications in complex fracture patterns, even if the initial clinical assessment is reassuring.

Abstract
Biochemical markers of bone-turnover have long been used to complement the radiological assessment of patients with metabolic bone disease. Their implementation in daily clinical practice has been helpful in the understanding of the pathogenesis of osteoporosis, the selection of the optimal dose and the understanding of the progression of the onset and resolution of treatment. Since they are derived from both cortical and trabecular bone, they reflect the metabolic activity of the entire skeleton rather than that of individual cells or the process of mineralisation. Quantitative changes in skeletal-turnover can be assessed easily and non-invasively by the measurement of bone-turnover markers. They are commonly subdivided into three categories; 1) bone-resorption markers, 2) osteoclast regulatory proteins and 3) bone-formation markers. Because of the rapidly accumulating new knowledge of bone matrix biochemistry, attempts have been made to use them in the interpretation and characterisation of various stages of the healing of fractures. Early knowledge of the individual progress of a fracture could help to avoid delayed or nonunion by enabling modification of the host’s biological response. The levels of bone-turnover markers vary throughout the course of fracture repair with their rates of change being dependent on the size of the fracture and the time that it will take to heal. However, their short-term biological variability, the relatively low bone specificity exerted, given that the production and destruction of collagen is not limited to bone, as well as the influence of the host’s metabolism on their concentration, produce considerable intra- and inter-individual variability in their interpretation. Despite this, the possible role of bone-turnover markers in the assessment of progression to union, the risks of delayed or nonunion and the impact of innovations to accelerate fracture healing must not be ignored.

Abstract
Fracture non-unions often complicate orthopaedic trauma. BMPs (bone morphogenetic proteins) are currently considered the most appealing osteoinductive agents. Applications of BMP-7 since January 2004 were prospectively recorded in a multicentre registry of aseptic femoral non-unions. The study included 30 patients who had undergone a median of 1 revision operation before BMP-7 application and who were followed up for a median 24 months. In 23/30 cases the application of BMP-7 was combined with revision of the fixation, and in 12 it was combined also with autograft. Non-union healing was verified in 26/30 cases in a median period of 6 months. No adverse events were associated with BMP-7 application. Our case series supports the safety and efficacy of BMP-7 in femoral non-unions. Multicentre networks and systematic, long-term follow-up of patients may improve understanding of this promising osteoinductive bone substitute.

Abstract
We investigated whether patients who underwent internal fixation for an isolated acetabular fracture were able to return to their previous sporting activities. We studied 52 consecutive patients with an isolated acetabular fracture who were operated on between January 2001 and December 2002. Their demographic details, fracture type, rehabilitation regime, outcome and complications were documented prospectively as was their level and frequency of participation in sport both before and after surgery. Quality of life was measured using the EuroQol-5D health outcome tool (EQ-5D). There was a significant reduction in level of activity, frequency of participation in sport (both p < 0.001) and EQ-5D scores in patients of all age groups compared to a normal English population (p = 0.001). A total of 22 (42%) were able to return to their previous level of activities: 35 (67%) were able to take part in sport at some level. Of all the parameters analysed, the Matta radiological follow-up criteria were the single best predictor for resumption of sporting activity and frequency of participation.

Abstract
Treatment of complex distal humeral fractures in older patients with osteopenic bone remains a major surgical challenge. We report the results of 11 patients over 75 years of age who underwent semiconstrained sloppy-hinge total elbow arthroplasty (TEA) due to comminuted intraarticular fractures of the distal humerus. There were 9 women and 2 men with a mean age of 79.6 years. The mean duration of follow up was 2.8 years. According to AO classification, there were 8 type C3 and 3 type C2 fractures. The mean time from injury to operation was 4.3 days and the mean length of hospital stay was 9.8 days. The elbow flexion/extension and forearm pronation/supination arc of motion averaged 107(0) and 121(0) respectively. The mean Mayo Elbow Performance Score (MEPS) was 90 points, equivalent to excellent result. One patient sustained a periprosthetic humeral fracture and signs of non-progressive radiolucency were found in 8 out of the 11 elbows. Our search in the English and International literature revealed 9 other clinical studies describing the results of TEA in 167 patients with 168 distal humeral fractures. The mean age of patients varied from 69 to 84.6 years and the mean follow up from 17.8 months to 7 years. The mean MEPS among the studies was between 85 and 95 points. Wound infection was diagnosed in 9 cases (5.4%) but component removal and subsequent reimplantation was only applied in 3 elbows (1.8%). Partial ulnar nerve lesions were reported in 11 patients (6.5%) and reflex sympathetic dystrophy was developed in 5 patients (3%). In 3 elbows (1.8%) a periprosthetic fracture after a fall was recorded. Radiolucent lines between the cement mantle and bone interface were described in 24 cases (14.3%) but the majority of them (17 cases) were stable and asymptomatic. In conclusion, TEA constitutes a viable treatment option for the complex distal humeral fractures in elderly and medically compromised patients. Careful patient selection and regular follow up evaluation are mandatory for achieving an optimal result and eliminating the risks of mismanagement and early implant failure.

Abstract
OBJECTIVE To examine the differences between severely injured older patients (aged over 65 years) compared with similarly injured younger adults in terms of incidence, inpatient mortality and factors predicting outcome. METHODS Data prospectively entered into the Trauma Audit and Research Network (TARN) database from our level I trauma unit over a 5-year period were retrospectively examined, with 3172 patients included in the final analysis. RESULTS Older patients accounted for 13.8% of those with severe injuries (Injury Severity Score 16 or more) and almost 2% of our trauma admissions overall. High energy injuries were responsible for the majority of these injuries though relatively minor trauma became increasingly important in older patients. Mortality rates in the older patients were more than twice those seen in the adult population (19% in the under 40's to almost 50% in the over 75's). Age, Injury Severity Score and Glasgow Coma Score continued to be predictive of mortality in older patients but other factors relevant in younger adults were not. CONCLUSIONS Patients in the older group without physiological derangement on admission were still at a relatively high risk of inpatient mortality. This was in contrast to the younger patients, suggesting that it might be more difficult to predict which older patients might benefit from more aggressive monitoring or treatment. Despite increased mortality in older patients, significant survival rates were achieved even in the oldest. Active treatment should not be withdrawn on the basis of age alone.

Abstract
Failure of fixation is a common problem in the treatment of osteoporotic fractures around the hip. The reinforcement of bone stock or of fixation of the implant may be a solution. Our study assesses the existing evidence for the use of bone substitutes in the management of these fractures in osteoporotic patients. Relevant publications were retrieved through Medline research and further scrutinised. Of 411 studies identified, 22 met the inclusion criteria, comprising 12 experimental and ten clinical reports. The clinical studies were evaluated with regard to their level of evidence. Only four were prospective and randomised. Polymethylmethacrylate and calcium-phosphate cements increased the primary stability of the implant-bone construct in all experimental and clinical studies, although there was considerable variation in the design of the studies. In randomised, controlled studies, augmentation of intracapsular fractures of the neck of the femur with calcium-phosphate cement was associated with poor long-term results. There was a lack of data on the long-term outcome for trochanteric fractures. Because there were only a few, randomised, controlled studies, there is currently poor evidence for the use of bone cement in the treatment of fractures of the hip.

Abstract
We describe a patient in whom an initially intact sciatic nerve became rapidly encased in heterotopic bone formed in the abductor compartment after reconstruction of the posterior wall of the acetabulum following fracture. Prompt excision and neural release followed by irradiation and administration of indometacin resulted in a full neurological recovery and no recurrence 27 months later.

Abstract
Trauma patients often present in a state of haemorrhagic shock. Blood products remain the gold standard of resuscitation, but allogeneic blood transfusions (ABTs) are associated with several risks. The stimulating effect of recombinant-erythropoietin (EPO-A) on erythropoiesis has raised interest in its administration as an alternative. The existing evidence on the early use of EPO-A in the acute phase of trauma patients management consists of only 14 publications. The level of evidence of these studies and the number of treated patients was not found to be adequate to support its generalised use, despite their favourable results. Its safety profile, the preliminary proofs of its efficacy, and the additional cyto-protective properties of EPO-A strongly encourage further controlled studies assessing its use in the acute setting of initial trauma management.

Abstract
The parameter of health economics in the use of any contemporary medical module plays a dominant role in decision making. A prospective nonrandomised comparative study of the direct medical costs on the first attempt of treating aseptic nonunions of tibial fractures, with either autologous-iliac-crest-bone-graft (ICBG) or bone morphogenetic protein-7 (BMP-7), is presented. Twenty-seven consecutive patients, who were successfully treated for fracture nonunions, were divided into two groups. Group 1 (n = 12) received ICBG and group 2 (n = 15) received BMP-7. All patients healed their nonunions, and the financial analysis presented represents a best-case scenario. Three out of 12 of the ICBG group required revision surgery while just one out of 15 required it in the BMP-7 group. Average hospital stay was 10.66 vs. 8.66 days, time-to-union 6.9 vs. 5.5 months, hospitals costs pound2,133.6 vs. pound1,733.33, and theatre costs were pound2,413.3 vs. pound906.67 for the ICBG and BMP-7 groups, respectively. The BMP-7 cost was pound3002.2. Fixation-implant was pound696.4 vs. pound592.3, radiology pound570 vs. pound270, outpatient pound495.8 vs. pound223.33, and other costs were pound451.6 vs. pound566.27 for the ICBG and BMP-7 groups, respectively. The average cost of treatment with BMP-7 was 6.78% higher (P = 0.1) than with ICBG, and most of this (41.1%) was related to the actual price of the BMP-7. In addition to the satisfactory efficacy and safety of BMP-7 in comparison to the gold standard of ICBG, as documented in multiple studies, its cost effectiveness is advocated favourably in this analysis.

Abstract
The incidence of proximal femoral fractures has increased significantly in recent years, and is expected to continue to rise with increasing life expectancy. However, the optimal method of treatment of these fractures is still debated. This article summarises current evidence concerning the most controversial issues in the treatment of intracapsular and extracapsular proximal femoral fractures. Despite initial enthusiasm, many new treatment options have been proved inferior to older, traditional methods, and physicians should be cautious when it comes to managing these fractures. It seems that meticulous surgical technique and implant selection according to fracture pattern and the characteristics of the individual patient offer the best route to optimal final outcome.

Abstract
The purpose of this study was to investigate the potential of Mesenchymal Stem Cells (MSCs) obtained from patients suffering from fractures to proliferate and differentiate towards osteogenic lineage with the use of autologous serum. In addition the effect of medium supplementation with the use of autologous serum obtained at different time points (patients' admission, first, third and seventh post-operative day) was investigated. In total eight patients suffering from lower limb long bone fractures with mean age of 39 (range 22-68 years) were included in this study. MSCs were isolated and cultivated in 10% of either Fetal Calf Serum (FCS) or autologous serum. Cellular proliferation was examined by XTT assay and Vybrant assay. The osteogenic differentiation was assessed by total calcium production and alkaline phosphatase production. Cellular proliferation and osteogenic differentiation was significantly statistically higher in patients' serum obtained on admission than in FCS. A negative effect on proliferation was noted with serum obtained on the first postoperative day. Subsequently, both proliferation and differentiation were gradually increased with autologous serum collected during the 3rd and 7th postoperatively days. Autologous serum obtained after fracture is superior in terms of proliferation and osteogenic differentiation to the currently used FCS. Surgery seems to have a negative effect on the quality of serum. These findings should be considered in cases where ex-vivo expansion of MSCs is needed. Recuperation of serum's quality takes place at a later time point within the first weeks after fracture.

Abstract
Posterior wall fractures are the commonest type of acetabular fracture. Nonoperative management is associated with significant complications and poor outcome. Consequently, open reduction and internal fixation has become increasingly common. In this article, inaugurating the new section of "how do I do it", we present our current approach to the treatment of posterior wall fractures of the acetabulum, including the preoperative planning, the details of the operative procedure in terms of patient's positioning and draping, surgical approach, osteosynthesis and wound closure.

Abstract
Fracture healing constitutes a complex and delicate physiological process. Local vascularity at the site of the fracture has been identified as one of the most significant parameters influencing the healing procedure. VEGF is the most important component of the regeneration of the vascular system at the fracture site. The aim of this review is to determine the evidence supporting the direct role of VEGF in the enhancement of fracture healing and the possible clinical use of VEGF for non-unions. The literature search was performed via the internet using the Medline. The key words which were searched in the abstracts were the terms "VEGF", "angiogenesis", "fracture", "bone" and "healing". Twenty-five articles were relevant to the topic of interest. A total of 11 articles were excluded from our research due to non conformity of their content to the inclusion criteria. Evidence retrieved suggests that VEGF could be extremely valuable for the treatment of critical size bone defects and that VEGF could have a direct effect on osteoprogenitor cells, mainly by promoting the differentiation of osteoblasts and by increasing the mineralisation of the regenerated bone. The former observation could have very interesting repercussions for the field of non-unions and the latter for the field of osteoporosis.

Abstract
A new scoring system is proposed in order to assist surgeons with the complex analysis associated with non-union surgery. Patients with non-union are rarely easily compared with one another and this has frustrated research in this field. We have therefore attributed values to clinical features based on clinical experience and research evidence, so that patients of similar complexity can be compared with one another. When greater experience with this scoring system has been gained it will be further refined and validated. We propose that surgeons with a sub specialist interest in non-union surgery use this system in reporting results, and that non- specialist surgeons use it to inform their decision to treat the fracture themselves, or refer to a sub specialist.

Abstract
The aim of this study was to evaluate the role of the lateral fluoroscopic view in optimising percutaneous sacroiliac screw insertion. Plastic pelvic models (n=26) were used for the introduction of 104 cannulated screws into the first and second sacral (S1 and S2) vertebral bodies, controlled with an image intensifier using either two views (inlet/outlet) for the right side (group A, n=52) or three views (inlet/outlet/lateral) for the left side (group B, n=52). The mean radiation exposure times for S1 were 18.6s and 14s, in groups A and B, respectively, and for S2 were 16.1s and 12.2s, respectively; 13 cortex perforations were noted in group A and 20 in group B. After insertion into S1, in both groups there were three cases of foraminal and none of central canal perforation, but after S2 insertion in both groups there were ten foraminal and five canal perforations. A higher incidence of misplacement of S1 screws was found in group A in comparison with group B (p=0.001), with sufficient data to support percutaneous screw fixation using inlet, outlet and lateral views rather than only inlet and outlet acquisition images.

Abstract
Translation of the achievements of basic science into everyday clinical practice remains a major issue in contemporary medicine, and is addressed through a new discipline, translational research, which aims to bridge the gap between basic and clinical research. Translational research encompasses laboratory studies, clinical demands, public health and health management, policies and economics; it is crucial in the evolution of contemporary biomedical science; and its interventions follow the political-economic, ethical-social and educational-scientific approaches. Translational research can progress through reorganisation of academic teams in a translational way. New academic posts translationally orientated are urgently needed, particularly in the field of trauma medicine, where lack of awareness of this new evolution is evident.

Abstract
A systematic review of the English literature over the last 30 years was conducted in order to investigate the correlation of the clinical outcome of different types of pelvic ring injuries to the method of treatment. Three basic therapeutic approaches were analysed: non-operative treatment (group A), stabilisation of anterior pelvis (group B) and internal fixation of posterior pelvis (group C). Of 818 retrieved reports, 27 case series, with 28 groups of patients and 1,641 patients, met our inclusion criteria. The quality of the literature was evaluated using a structured questionnaire. Outcomes of the eligible studies were summarised by the medians of the reported results. Most of the component studies were of fair or poor quality. Certain radiological results (quality of reduction, malunion rates) were significantly better in group C. From the functional point of view only walking capacity was proved to be significantly better in the groups of operative treatment compared to the non-operative group.

Abstract
UNLABELLED The purpose of this study was to evaluate the long-term outcome of open patellar fractures and to compare their results with a matched group of patients with closed patellar injuries. Sixteen patients with open patellar fractures were followed up at a mean of 45 months (15-100). Functional outcome was evaluated using a visual analogue scale (VAS) and Knee and Osteoarthritis Outcome Score (KOOS). Sixteen patients with closed patellar fractures, matched for age, sex and fracture pattern, were randomly selected from our database to form the control group. RESULTS AND CONCLUSION The most common mechanism of injury in the open patellar group was road traffic accidents (94%) whereas in the closed group it was falls (62%). A greater number of patients had associated injuries in the open patellar fracture group compared to the closed fracture group (13 versus 5, p=0.01). The injury severity score (ISS) was significantly higher in the open patellar group (mean 22.75, range 5-50) compared with the closed group (mean 7.06, range 4-20); p<0.0001. Patients with open patellar fractures also had a higher, though not statistically significant, incidence of complications, lower KOOS score and higher VAS for pain. LEVEL OF EVIDENCE Therapeutic study. Level III (Matched Cohort Study) [to evaluate the long-term outcome of open patellar fractures and to compare their results with a matched group of patients with closed patellar injuries].

Abstract
We have undertaken a prospective study in patients with a fracture of the femoral shaft requiring intramedullary nailing to test the hypothesis that the femoral canal could be a potential source of the second hit phenomenon. We determined the local femoral intramedullary and peripheral release of interleukin-6 (IL-6) after fracture and subsequent intramedullary reaming. In all patients, the fracture caused a significant increase in the local femoral concentrations of IL-6 compared to a femoral control group. The concentration of IL-6 in the local femoral environment was significantly higher than in the patients own matched blood samples from their peripheral circulation. The magnitude of the local femoral release of IL-6 after femoral fracture was independent of the injury severity score and whether the fracture was closed or open. In patients who underwent intramedullary reaming of the femoral canal a further significant local release of IL-6 was demonstrated, providing evidence that intramedullary reaming can cause a significant local inflammatory reaction.

Abstract
A large number of aids have been conceived and introduced into clinical practice (nutritional supplements, local dressings, technical innovations) aimed at facilitating and optimising wound healing in both acute and chronic wound settings. Among these advances, negative pressure wound therapy (NPWT) has been introduced during the last 30 years, and has been analysed in over 400 manuscripts of the English, Russian and German literature. Until very recently, vacuum assisted closure (VAC) (KCI, TX, USA) has been the only readily available commercial device that provides localised negative pressure to the wound and is the predominant agent used to deliver NPWT featured in this review. We conducted a comprehensive review of the existing clinical evidence of the English literature on the applications of NPWT in the acute setting of trauma and burns of the lower extremity. Overall, 16 clinical studies have been evaluated and scrutinised as to the safety and the efficacy of this adjunct therapy in the specific environment of trauma. Effectiveness was comparable to the standard dressing and wound coverage methods. The existing clinical evidence justifies its application in lower limb injuries associated with soft tissue trauma.

Abstract
Farmyard injuries in young adults and the elderly usually result from machinery accidents, whereas children tend to be injured by runovers and motor vehicle collisions. A variety of farmyard injuries secondary to environmental and human factors may cause permanent disability or even death. Common injuries include lacerations, hand injuries, amputations, farm animal bites, fractures and dislocations. Special considerations should be taken into account when treating these injuries, focusing on their noteworthy bacterial load in order to minimise the risk of chronic morbidity.

Abstract
Necrotising fasciitis is a rapidly progressive, life threatening soft tissue infection. In a significant proportion of patients, the extremities are involved as a result of trauma, needle puncture or extravasation of drugs, often leading to limb loss and devastating disability. In this systematic review of necrotising fasciitis of the upper and lower extremities, we report on the clinical characteristics, the predisposing factors, the associated diseases, the pathogenic bacteria, the surgical treatment and the final outcome in terms of limb loss and mortality. Data for a total of 451 patients were analysed for each parameter of interest. A percentage of 22.3% of the reviewed patients underwent amputation or disarticulation of a limb following failure of multiple debridements to control infection and the mortality rate was estimated as high as 21.9%.
