Current treatment options for displaced acetabular fractures in elderly patients include non-surgical management, surgical fixation and surgical fixation with simultaneous hip replacement, the so-called “fix-and-replace”™. There remains a paucity of evidence to guide surgeons in decision making for these difficult injuries. The aim of this study was to assess the feasibility of performing an appropriately powered RCT between treatment options for acetabular fractures in older patients. This was an NIHR funded feasibility triple-arm RCT with participation from 7 NHS MTCs. Patients older than 60 were recruited if they had an acetabular fracture deemed sufficiently displaced for the treating surgeon to consider surgical fixation. Randomisation was performed on a 1:1:1 basis. The three treatment arms were non-surgical management, surgical fixation and fix-and-replace. Feasibility was assessed by willingness of patients to participate and clinicians to recruit, drop out rate, estimates of standard deviation to inform the sample size calculation for the full trial and completion rates to inform design of a future definitive trial. EQ-5D was the primary outcome measure at 6 months, OHS and Disability Rating Index were secondary outcome measures. Of 117 eligible patients, 60 were randomised whilst 50 declined study participation. Nine patients did not receive their allocated intervention. Analysis was performed on an intention to treat basis. During the study period 4 patients withdrew before final review, 4 patients died and 1 was lost to follow-up. The estimated sample size for a full scale study was calculated to be 1474 participants for an EQ-5D MCID of 0.06 with a power of 0.8. This feasibility study suggests a full scale trial would require international collaboration. This study also has provided observed safety data regarding mortality and morbidity for the fix-and-replace procedure to aid surgeons in the decision-making process when considering treatment options.
The management of fractures of the medial epicondyle is one of the greatest controversies in paediatric fracture care, with uncertainty concerning the need for surgery. The British Society of Children’s Orthopaedic Surgery prioritized this as their most important research question in paediatric trauma. This is the protocol for a randomized controlled, multicentre, prospective superiority trial of operative fixation versus nonoperative treatment for displaced medial epicondyle fractures: the Surgery or Cast of the EpicoNdyle in Children’s Elbows (SCIENCE) trial. Children aged seven to 15 years old inclusive, who have sustained a displaced fracture of the medial epicondyle, are eligible to take part. Baseline function using the Patient-Reported Outcomes Measurement Information System (PROMIS) upper limb score, pain measured using the Wong Baker FACES pain scale, and quality of life (QoL) assessed with the EuroQol five-dimension questionnaire for younger patients (EQ-5D-Y) will be collected. Each patient will be randomly allocated (1:1, stratified using a minimization algorithm by centre and initial elbow dislocation status (i.e. dislocated or not-dislocated at presentation to the emergency department)) to either a regimen of the operative fixation or non-surgical treatment.Aims
Methods
To compare the cost-effectiveness of high-dose, dual-antibiotic cement versus single-antibiotic cement for the treatment of displaced intracapsular hip fractures in older adults. Using data from a multicentre randomized controlled trial (World Hip Trauma Evaluation 8 (WHiTE-8)) in the UK, a within-trial economic evaluation was conducted. Resource usage was measured over 120 days post randomization, and cost-effectiveness was reported in terms of incremental cost per quality-adjusted life year (QALY), gained from the UK NHS and personal social services (PSS) perspective in the base-case analysis. Methodological uncertainty was addressed using sensitivity analysis, while decision uncertainty was handled using confidence ellipses and cost-effectiveness acceptability curves.Aims
Methods
The aim of this study was to describe the current pathways of care for patients with a fracture of the hip in five low- and middle-income countries (LMIC) in South Asia (Nepal and Sri Lanka) and Southeast Asia (Malaysia, Thailand, and the Philippines). The World Health Organization Service Availability and Readiness Assessment tool was used to collect data on the care of hip fractures in Malaysia, Thailand, the Philippines, Sri Lanka, and Nepal. Respondents were asked to provide details about the current pathway of care for patients with hip fracture, including pre-hospital transport, time to admission, time to surgery, and time to weightbearing, along with healthcare professionals involved at different stages of care, information on discharge, and patient follow-up.Aims
Methods
The evidence demonstrating the superiority of early MRI has led to increased use of MRI in clinical pathways for acute wrist trauma. The aim of this study was to describe the radiological characteristics and the inter-observer reliability of a new MRI based classification system for scaphoid injuries in a consecutive series of patients. We identified 80 consecutive patients with acute scaphoid injuries at one centre who had presented within four weeks of injury. The radiographs and MRI scans were assessed by four observers, two radiologists, and two hand surgeons, using both pre-existing classifications and a new MRI based classification tool, the Oxford Scaphoid MRI Assessment Rating Tool (OxSMART). The OxSMART was used to categorize scaphoid injuries into three grades: contusion (grade 1); unicortical fracture (grade 2); and complete bicortical fracture (grade 3).Aims
Methods
There has been an increasing use of early operative fixation for scaphoid fractures, despite uncertain evidence. We conducted a meta-analysis to evaluate up-to-date evidence from randomized controlled trials (RCTs), comparing the effectiveness of the operative and nonoperative treatment of undisplaced and minimally displaced (≤ 2 mm displacement) scaphoid fractures. A systematic review of seven databases was performed from the dates of their inception until the end of March 2021 to identify eligible RCTs. Reference lists of the included studies were screened. No language restrictions were applied. The primary outcome was the patient-reported outcome measure of wrist function at 12 months after injury. A meta-analysis was performed for function, pain, range of motion, grip strength, and union. Complications were reported narratively.Aims

This study aims to assess the feasibility of conducting a pragmatic, multicentre randomized controlled trial (RCT) to test the clinical and cost-effectiveness of an informal caregiver training programme to support the recovery of people following hip fracture surgery. This will be a mixed-methods feasibility RCT, recruiting 60 patients following hip fracture surgery and their informal caregivers. Patients will be randomized to usual NHS care, versus usual NHS care plus a caregiver-patient dyad training programme (HIP HELPER). This programme will comprise of three, one-hour, one-to-one training sessions for the patient and caregiver, delivered by a nurse, physiotherapist, or occupational therapist. Training will be delivered in the hospital setting pre-patient discharge. It will include practical skills for rehabilitation such as: transfers and walking; recovery goal setting and expectations; pacing and stress management techniques; and introduction to the HIP HELPER Caregiver Workbook, which provides information on recovery, exercises, worksheets, and goal-setting plans to facilitate a ‘good’ recovery. After discharge, patients and caregivers will be supported in delivering rehabilitation through three telephone coaching sessions. Data, collected at baseline and four months post-randomization, will include: screening logs, intervention logs, fidelity checklists, quality assurance monitoring visit data, and clinical outcomes assessing quality of life, physical, emotional, adverse events, and resource use outcomes. The acceptability of the study intervention and RCT design will be explored through qualitative methods with 20 participants (patients and informal caregivers) and 12 health professionals.Aims
Methods
To explore staff experiences of a multicentre pilot randomized controlled trial (RCT) comparing intramedullary nails and circular frame external fixation for segmental tibial fractures. A purposeful sample of 19 staff (nine surgeons) involved in the study participated in an interview. Interviews explored participants’ experience and views of the study and the treatments. The interviews drew on phenomenology, were face-to-face or by telephone, and were analyzed using thematic analysis.Aims

Our purpose was to describe an unusual series of 21 patients with fungal osteomyelitis after an anterior cruciate ligament reconstruction (ACL-R). We present a case-series of consecutive patients treated at our institution due to a severe fungal osteomyelitis after an arthroscopic ACL-R from November 2005 to March 2015. Patients were referred to our institution from different areas of our country. We evaluated the amount of bone resection required, type of final reconstructive procedure performed, and Musculoskeletal Tumor Society (MSTS) functional score.Aims

The aim was to examine the descriptive epidemiology of Slipped Capital Femoral Epiphysis, with respect to geography and time. We extracted all children with a diagnosis of Slipped Capital Femoral Epiphysis from the Clinical Practice Research Database between 1990 and 2014 (24 years). CPRD is the world's largest database of primary care, which encompasses 8% of the UK population. CPRD was linked to Hospital Episode Statistics, and a validation algorithm applied to maximise sensitivity and specificity of the cases finding methodology. Poisson confidence intervals were calculated, and poison regression used. 596 cases of SCFE were identified. The internal validation algorithm supported a SCFE diagnosis in 88% cases. The age and sex distribution of cases mirrored that in the literature, offering external validity to the cases identified. There was no significant change in the incidence of SCFE over the 24-year study period, with the overall incidence being 4.8 cases per 100,00 0–16 year olds. There was no significant geographic variation in SCFE within the UK. There was a positive association with rising socioeconomic deprivation (p<0.01). There was no seasonal variation in presentation. This study found no evidence to support the common belief that SCFE incidence is increasing, and for the first time demonstrated an association with socioeconomic deprivation. The results are important for considering the feasibility of intervention studies, and offer insights into the disease aetiology.
Many different designs of total hip arthroplasty
(THA) with varying performance and cost are available. The identification
of those which are the most cost-effective could allow significant
cost-savings. We used an established Markov model to examine the
cost effectiveness of five frequently used categories of THA which differed
according to bearing surface and mode of fixation, using data from
the National Joint Registry for England and Wales. Kaplan–Meier
analyses of rates of revision for men and women were modelled with
parametric distributions. Costs of devices were provided by the
NHS Supply Chain and associated costs were taken from existing studies.
Lifetime costs, lifetime quality-adjusted-life-years (QALYs) and
the probability of a device being cost effective at a willingness
to pay £20 000/QALY were included in the models. The differences in QALYs between different categories of implant
were extremely small (<
0.0039 QALYs for men or women over the
patient’s lifetime) and differences in cost were also marginal (£2500
to £3000 in the same time period). As a result, the probability
of any particular device being the most cost effective was very
sensitive to small, plausible changes in quality of life estimates
and cost. Our results suggest that available evidence does not support
recommending a particular device on cost effectiveness grounds alone.
We would recommend that the choice of prosthesis should be determined
by the rate of revision, local costs and the preferences of the
surgeon and patient. Cite this article:
We sought to evaluate the impact of a dedicated weekly ortho-plastics operating list on our ability to provide definitive soft tissue cover of open lower limb fractures within 72 hours. We reviewed all open lower limb fractures at our centre before and after the introduction of an ortho-plastics list to determine whether definitive soft tissue coverage was achieved within 72 hours. There were 23 open lower limb fractures at our centre in 2012 before the introduction of the ortho-plastics operating list of which only 7 (30%) had definitive soft tissue coverage within 72 hours. We hypothesised that the main reason for this was not patient or injury related factors but rather the logistical difficulties of coordinating theatre time on a routine trauma list with senior orthopaedic and plastic surgeon availability. To test this hypothesis we re-audited our time to soft tissue cover six months after the introduction of the ortho-plastics list and 70% of cases achieved coverage within 72 hours. Achieving definitive soft tissue coverage of open lower limb fractures within 72 hours of injury is a challenge. A dedicated weekly ortho-plastics operating list significantly improves our ability to deliver this service.
Autologous bone graft has been used in the treatment of complex bone defects for more than a century. Morbidity associated with the harvest of this bone graft has led orthopaedic surgeons to seek alternative therapies in the treatment of long bone non-unions. The aim of this study was to determine whether the use of demineralised bone matrix as a bone healing adjunct improves clinical outcomes in adult patients with long bone non-union. A systematic search was carried out of the peer-reviewed English language literature to identify all relevant studies. The search strategy returned a total of 47 studies. Five of these studies were relevant to the research question. The studies were critically assessed and where appropriate combined in a meta-analysis. 4 non-comparative studies and one comparative study were reviewed. An overall estimate of the rate of union for the five studies was 86% (95%CI: 71–94%). The one comparative study demonstrated the relative risk (RR) of healing was not significantly better than in patients treated with autologous bone graft; RR=1.03 (95%CI 0.96–1.12). There are limited data to support the use of demineralised bone matrix in the treatment of long bone non-union. Demineralised bone matrix is likely to be similarly effective to other treatments in the management of non-union. This study confirms the clinical and ethical requirements to proceed with a randomised controlled trial to test the effectiveness of this intervention.
The Patient Archiving and Communication System (PACS) has revolutionised the way that radiographs are stored and viewed in orthopaedic surgery. A recent advance has been the ability to upload images directly from the image intensifier to PACS. We postulated that this facility may reduce the need for post operative ‘check’ radiographs following many orthopaedic trauma procedures. We performed an audit of post-operative radiographs requested in our University Hospital over three time periods: 31 days immediately before the direct upload facility was introduced, 31 days immediately after and a 31 day period two months later. Details from the operating lists were cross-referenced with image intensifier records to identify cases where it had been used. PACS records were then checked to determine if these images were available to view and if a formal ‘check’ radiograph was performed in the period prior to discharge.Introduction
Patients and Method
Locking compression plate (LCP) fixation is an established method of treatment of distal third tibial fractures. No biomechanical data exists in the literature regarding their use. Additionally no data exists on the biomechanical advantage of locking screw fixation over non-locking screw fixation for these fractures. In this study the axial and torsional stiffness, axial load to failure and fatigue performance of a 3.5 mm LCP medial distal tibia Synthes plate was evaluated for the stabilisation of distal third tibial fractures. Additionally the performance of the plate in uni and bicortical locked mode as well as non-locked mode was evaluated. A standardized oblique fracture pattern was created in the tibial metaphysis of 3rd generation composite tibias, 40 mm from the distal end of the tibia (AO 43-A2.3). A 10mm fracture gap was used to model a comminuted metaphyseal fracture. A 3.5 mm medial distal tibia LCP was applied with bi or unicortical locking or bicortical non-locking screws to 5 tibias respectively. All the bio-mechanical tests were performed on a Bose 3510 Electroforce material testing machine. A ramp to load, loading profile was used to determine the static axial and torsional performance of the construct. Fatigue testing simulated a 6 week gradual weight bearing régime with the load increasing every two weeks by 400N until either 250,000 cycles were completed or the construct failed.Introduction
Methods
Shockwave therapy has been shown to induce osteoneogenesis in animal models. The mechanism of action is unclear, but experimental evidence suggests micro-fracture formation and increased blood flow as the most likely explanation. Several reports from Europe have suggested good results from the treatment of delayed fracture union with shock-waves. We present the results of a randomised double-blind placebo-controlled pilot study. Fourteen patients with clinically and radiologically confirmed delayed union of long-bones consented to enter the trial. The treatment group had a single application of 3000 high-energy shockwaves using the Stortz SLK unit with image intensifier control. The control group had the exactly the same treatment but with an ‘air-gap’ interposition to create a placebo-shockwave. Each patient was followed-up with serial radiographs as well as visual analogue pain scores and EuroQol assessments. All of the patients were reviewed for a minimum of three years post treatment.Background
