Musculoskeletal (MSK) injuries are one of the leading causes of disability worldwide. Despite improvements in trauma-related morbidity and mortality in high-income countries over recent years, outcomes following MSK injuries in low and middle-income countries, such as South Africa (SA), have not. Despite governmental recognition that this is required, funding and research into this significant health burden are limited within SA. This study aims to identify research priorities within MSK trauma care using a consensus-based approach amongst MSK health care practitioners within SA. Members from the Orthopaedic Research Collaborative (ORCA), based in SA, collaborated using a two round modified Delphi technique to form a consensus on research priorities within orthopaedic trauma care. Members involved in the process were orthopaedic healthcare practitioners within SA. Participants from the ORCA network, working within SA, scored research priorities across two Delphi rounds from low to high priority. We have published the overall top 10 research priorities for this Delphi process. Questions were focused on two broad groups - clinical effectiveness in trauma care and general trauma public health care. Both groups were represented by the top two priorities, with the highest ranked question regarding the overall impact of trauma in SA and the second regarding the clinical treatment of open fractures. This study has defined research priorities within orthopaedic trauma in South Africa. Our vision is that by establishing consensus on these research priorities, policy and research funding will be directed into these areas. This should ultimately improve musculoskeletal trauma care across South Africa and its significant health and socioeconomic impacts

Developmental Dysplasia of the Hip (DDH) is the most common orthopaedic disorder in newborns. Whilst the Pavlik harness is one of the most frequently used treatments for DDH, there is immense variability in treatment parameters reported in the literature and in clinical practice, leading to difficulties in standardising teaching and comparing outcomes. In the absence of definitive quantitative evidence for the optimal Pavlik harness management strategy in DDH, we addressed this problem by scientifically obtaining international expert-based consensus on the same. An initial list of items relevant to Pavlik harness treatment was derived by systematic review of the literature according to PRISMA criteria and reviewed by two expert clinicians in DDH management. Delphi methodology was used to guide serial rounds of surveying and feedback to content matter experts from the International Hip Dysplasia Institute (IHDI), a collaborative group of paediatric orthopaedic surgeons with expertise in the management of DDH. Rounds of surveying continued in the same manner until consensus was reached. Importance ratings were derived from each round of surveying by calculating median score responses on the 5-point Likert scale for each item. Items requiring clarification or those with a median score of below 4 (“agree”) were modified as needed prior to each subsequent round. Consensus was considered reached when 90% or more of the items had an interquartile range (IQR) of ≤ 1. This value indicates low sample deviation and is accepted as having achieved consensus. This was followed by a corroboration of face validity to derive the final set of management principles. The literature search and expert review identified an initial list of 66 items in 8 categories relevant to Pavlik harness management. Four rounds of structured surveying were required to reach consensus. Following a final round of face validity, a definitive list of 33 items in 8 categories met consensus by the experts. These items were tabulated and presented as “General Principles of Pavlik Harness Treatment for DDH” and “Pavlik Harness Treatment by Severity of Hip Dysplasia”. Furthermore, highly contentious items were identified as important future areas of study and will be discussed. We have developed a comprehensive set of principles derived by expert consensus to assist clinicians, and for use as a teaching resource, in the non-operative management of DDH using the Pavlik harness. We have gained consensus on both the general principles of Pavlik harness treatment as well as the detailed treatment of hip subtypes seen across the spectrum of pathology of DDH. Furthermore, this study has also served to generate a list of the most controversial areas in the non-operative management of DDH which should be considered high priority for future study to further refine and optimise the outcomes of children with developmental hip dysplasia

Aim. Surgical treatment of ankle fractures comes with a substantial risk of complications, including infection. An unambiguously definition of fracture-related infections (FRI) has been missing. Recently, FRI has been defined by a consensus group with a diagnostic algorithm containing suggestive and confirmatory criteria. The aim of the current study was to report the prevalence of FRI in patients operated for ankle fractures and to assess the applicability of the diagnostic algorithm from the consensus group. Method. Records of all patients with surgically treated ankle fractures from 2015 to 2019 were retrospectively reviewed for signs of postoperative infections. Patients with suspected infection were stratified according to confirmatory or suggestive criteria of FRI. Rate of FRI among patients with confirmatory and suggestive criteria were calculated. Results. Suspected infection was found in 104 (10%) out of 1004 patients. Among those patients, confirmatory criteria were met in 76/104 (73%) patients and suggestive criteria were met in 28/104 (27%) at first evaluation. Patients with clinical confirmatory criteria (N= 76) were diagnosed with FRI. Patients with suggestive criteria were further examined with either bacterial sampling at the outpatient clinic, revision surgery including bacterial sampling, or a wait-and-see approach. Eleven (39%) of the 28 patients had positive cultures and were therefore diagnosed as having FRI at second evaluation. In total 87 (9%) patients were diagnosed with FRI according to the consensus definition. Only 73 (70%) of the 104 patients with suspected FRI had adequate bacterial sampling. Conclusions. The prevalence of FRI, applying the FRI-consensus criteria, for patients with surgically treated ankle fractures was 9%. Twenty-two percent of patients who met the confirmatory criteria had negative bacterial cultures. The current study shows that we did not have a systematic approach to patients with suspected FRI as recommended by the consensus group. A systematic approach to adequate bacterial sampling when FRI is suspected is paramount. The consensus definition of FRI and its diagnostic algorithm facilitates such an approach

Aims. Weightbearing instructions after musculoskeletal injury or orthopaedic surgery are a key aspect of the rehabilitation pathway and prescription. The terminology used to describe the weightbearing status of the patient is variable; many different terms are used, and there is recognition and evidence that the lack of standardized terminology contributes to confusion in practice. Methods. A consensus exercise was conducted involving all the major stakeholders in the patient journey for those with musculoskeletal injury. The consensus exercise primary aim was to seek agreement on a standardized set of terminology for weightbearing instructions. Results. A pre-meeting questionnaire was conducted. The one-day consensus meeting, including patient representatives, identified three agreed terms only to be used in defining the weightbearing status of the patient: 1) non-weightbearing; 2) limited weightbearing; and 3) unrestricted weightbearing. Conclusion. This study represents the first and only exercise in standardizing rehabilitation terminology in orthopaedics, as agreed by all major stakeholders in the patient pathway and the patients themselves. The standardization of language allows for higher-quality and more accurate research to be conducted, and is one small part of the bigger picture in increasing the mobility of patients after orthopaedic injury or surgery.

Referral patterns in spine clinic of young patients with suspected scoliosis is suboptimal with 19% of late referrals and 42% of inappropriate referrals. Patients' triage and prioritisation in spine clinic is a strategy to ensure that health care allocation is done according to the level of health needs, favoring effective management and efficient use of health care resources use. The objective of the study is to elaborate a model for triage and prioritisation of young patients in spine clinic based on expert consensus and literature on best practices. This projects was structured in three parts: 1)We documented best evidence. We conducted a review of empirical studies evaluating triage and prioritisation initiatives in order to identify key components for intervention success. 2)We elaborate a model of health care delivery with the professionals of a local paediatric spine clinic. In this model, the triage and prioritisation algorithm was developed from list of potential factors (demographics, signs and perceived symptoms, provisional diagnoses and known co-morbidities, results of preliminary physical examination and radiological findings) that was submitted to five paediatric orthopaedic surgeons for rating according to their potential relevance to orient prioritisation decisions. 3) We compared the professionals' model of health care delivery to the literature synthesis in order to propose the best model. Seven key components of triage and prioritisation systems were identified: centralised review of referral requests, list of consensual objectives criteria for triage, fast track evaluation of urgent cases, selection of cases for management at point of triage, cases prioritisation to main consultant, multidisciplinary evaluation and alternatives pathways. The consensual decision algorithm confirmed that cases who should be seen in priority are immature patients presenting with a significant trunk deformity. In addition, presence of persisting neurological symptoms, severe incapacitating pain or night pain, as well as abnormal scan or MRI findings were considered as urgent/PI priority. Cases characteristics for evaluation by nurse practitioners as well as alternative pathways of management were defined. Acceptability, compatibility, clinical relevance and discriminant capacity of the new model of health care delivery were satisfactorily demonstrated. Consensus was easily reached between the five respondents on factors supporting decisions to prioritise patients in spine clinic for suspected spinal deformity. Refinements to the initially proposed model according the identified key features from the literature, led to a final model of health care delivery that is evidence-base, feasible and coherent with the local context. Future implementation of this model should facilitate timely and appropriate health care delivery and best use of health care resources according to patients' needs

The aim of this study is to determine evidence-based guidelines on functional outcomes following common thoracolumbar injuries using a synthesis of systematic literature reviews and consensus expert opinion. A questionnaire was created comprising five cases representative of common thoracolumbar injuries (a thoracic compression fracture, a flexion distraction injury and burst fractures each with varied location, patient demographics and treatment strategies). For each scenario five questions about expected functional outcomes were posed. Questionnaires were distributed to the Spine Trauma Study Group. Responses were combined with available data from a systematic review of the same injuries and outcomes to create consensus evidence based guidelines. The survey was completed by 31 (57%) of 53 surgeons representing 20 centres across North America. The systematic reviews identified 49 appropriate studies. One year following a L1 burst fracture, a heavy laborer, treated with protective mobilization (cast or brace) has a 40% chance of being pain free, 70% chance of regaining pre-injury range of motion, can expect to be re-employed within 4–6 months and be able to participate in high impact exercise and contact sport with no or minimal limitation. Length of inpatient stay averages 4–5 days. One year following posterior short segment stabilization of a L1 bust fracture in a college football player, there is an expected 45% chance of being pain free and 55% chance of regaining pre-injury ROM. While an ultimate return to high impact exercise and contact sports is anticipated, 32% of experts expect the injury to end a college football career. Results for the other trauma scenarios are included. This combination of literature and expert opinion represents the best available evidence on functional prognosis after thoracolumbar trauma. By providing consistent, accurate information surgeons and other care path providers will help patients develop realistic expectations, which may shape and improve their ultimate outcome

Clinical pathways are optimal patient care processes that have been developed to improve the quality of care for patients. Anecdotal evidence has suggested that patients presenting to the healthcare system with rotator cuff tears experience less than ideal quality care plagued by lengthy wait times, challenges in coordinating care, and inefficient use of healthcare resources. Therefore, diagnosis and treatment of patients with rotator cuff tears are in need of quality improvement through evidence-informed decision making. The purpose of this study is to develop a clinical pathway for patients presenting to the healthcare system with rotator cuff tears. The following steps were taken in developing the clinical pathway: 1) a multidisciplinary expert panel was formed; 2) goals of the clinical pathway were identified by the panel; 3) the literature and current clinical practices for best practice were reviewed; 4) recommendations for treatment algorithms were developed using consensus methods. The panel consisted of fourteen experts representing the two largest cities in Alberta, Canada (Edmonton and Calgary). The team consisted of at least one member from the clinical domains of sport medicine, orthopaedic surgery, athletic therapy, and physiotherapy. The first goal of the clinical pathway was to standardise screening, diagnosis, and physical examination of the patient. The second goal was to provide recommendations for appropriate investigations. The final goal was to map steps in the patients' care pathway including sequencing and timing recommendations for treatment and interventions. Best practices were reviewed by the panel and using a modified Delphi method, clinical pathways for three types of rotator cuff tears (acute, chronic, and acute-on-chronic) were developed. A clinical pathway that reflected best practices was developed from the literature and experts. The clinical pathway for diagnosis and treatment of patients with rotator cuff pathology will help to standardised patient care, improve patient flow, reduce unnecessary interventions, reduce healthcare utilisation and costs, and improve the quality of patient care

Introduction. Despite the established guidelines on lower extremity free flap reconstruction by the British Orthopaedic Association Standard for Trauma (BOAST-4) the post-operative care has yet to be standardised. There is currently no coherent evidence in the literature regarding clinical monitoring, warming, dangling and compression; the optimal regimes and their respective physiological benefits. The aim of this study is to survey all UK Major Trauma Centres (MTCs) with regards to the post-operative care of lower extremity free flaps and elucidate the current protocols for clinical monitoring, warming, dangling and compression. Materials & Methods. All UK-based adult MTCs were surveyed. We formulated a detailed questionnaire to enquire about the post-operative care of lower extremity free flap reconstructions; the number of free flap reconstructions per month and take backs per month and for which post-operative methods a protocol is used in each MTC. We asked specific questions concerning: clinical monitoring, warming, dangling and compression. This questionnaire was distributed to consultant leads in the form of multiple choice questions, with an option of free-text box for further comments, using JISC online surveys. Results were analysed in Excel and presented in percentages. Results. The 28 adult MTCs were contacted. The results showed a lack of formal regional protocols with great variability, suggesting there is no general consensus on post-operative care of lower extremity free flap reconstructions with regards to clinical monitoring, warming, dangling and compression. Conclusions. This survey of UK MTCs on the post-operative protocols for lower extremity free flap reconstruction demonstrated lack of evidence, consensus and large variability in common practice which requires standardisation

Utility score is a preference-based measure of general health state – where 0 is equal to death, and 1 is equal to perfect health. To understand a patient's smallest perceptible change in utility score, the minimal clinically important difference (MCID) can be calculated. However, there are multiple methods to calculate MCID with no consensus about which method is most appropriate. The aim of this study is to calculate MCID values for the Veterans-RAND 12 (VR12) utility score using varying methods. Our hypothesis is that different methods will yield different MCID values. A tertiary institutional registry (SMART) was used as the study cohort. Patients who underwent unilateral TKA for osteoarthritis from January 2012 to January 2020 were included. Utility score was calculated from VR12 responses using the standardised Brazier's method. Distribution and anchor methods were used for the MCID calculation. For distribution methods, 0.5 standard deviations of the baseline and change scores were used. For anchor methods, the physical and emotional anchor questions in the VR12 survey were used to benchmark utility score outcomes. Anchor methods included mean difference in change score, mean difference in 12 month score, and receiver operating characteristics (ROC) analysis with the Youden index. Complete case analysis of 1735 out of 1809 eligible patients was performed. Significant variation in the MCID estimates for VR12 utility score were reported dependent on the calculation method used. The MCID estimate from 0.5 standard deviations of the change score was 0.083. The MCID estimate from the ROC analysis method using physical or emotional anchor question improvement was 0.115 (CI95 0.08-0.14; AUC 0.656). Different MCID calculation methods yielded different MCID values. Our results suggest that MCID is not an umbrella concept but rather many distinct concepts. A general consensus is required to standardise how MCID is defined, calculated, and applied in clinical practice

Introduction. A greater emphasis has been placed on fracture related infection (FRI) orthopaedic practice as a separate entity in recent years. Since the publication of the FRI consensus definition and guidelines, there has been an increase in the published literature on the topic and a move towards considering FRI as separate from general orthopaedic practice and as work that requires a more specialist approach. The aim of this study was to audit current FRI practice in the UK. Materials & Methods. Orthopaedic practice related to FRI in the UK was audited using a semi-structured questionnaire. Respondents were from a range of institutions, specialties and clinical roles to reflect the multi-disciplinary nature of treating FRI. The online tool SurveyMonkey was used to share the survey at the 2022 annual meeting of the British Limb Reconstruction Society. Twenty-one questions were asked in the following domains: scope of practice, theatre and clinic capacity, availability of the multidisciplinary team, renumeration for work and scope of FRI networks. Results. Of the 36 respondents, the majority (64%) worked in a major trauma centre. In the majority of cases, bone infection was managed by the limb reconstruction team (68%) although in most centres the wider team was often also involved including the general on call, the trauma team and the arthroplasty team. When referrals were made elsewhere, this was usually done to known individuals rather than established FRI networks. 80% of respondents said that there was a bone infection MDT in their unit and this usually met weekly. This usually included orthopaedics and microbiology but plastics in only 43% of cases and radiology in only 23% of cases. Most respondents said that the lack of funding and appropriate tariffs were the main barrier to FRI management locally (62%) and nationally (83%). Most respondents (83%) said that bone infection practice should be centralised. The overwhelming majority of this cohort (90%) said that patient outcomes would be improved by cases being managed in dedicated centres. Conclusions. There is variation in practice for the management of bone infection in the UK. This reflects the lack of clear national guidelines and the lack of established networks for management and onward referral. There is agreement that patient outcomes would be improved by more formal networks and specialised centres but also recognition that remuneration is a significant barrier to implementing change. This survey reflects practice in units with an interest in limb reconstruction and bone infection. Further work is needed to evaluate practice across district general hospitals in the UK and to build consensus around best practice and national strategies for improved care

Paget's disease of bone (PDB) is characterised by increased bone resorption and development of an erratic bone structure that is highly fragile and susceptible to fracture. In addition, altered joint biomechanics lead to arthritis, more often in the hip and pelvis, resulting in disability and a Total hip Arthroplasty (THA) may be required. THA in PDB is associated with more complications compared to normal population. There is no consensus on the type of arthroplasty that performs better in people with PDB. To our knowledge, there is no meta-analysis in literature on this rare problem. We undertook a systematic review and meta-analysis to compare the effectiveness of cemented versus cementless THA in patients with PDB. PRISMA guidelines were followed. Search strings were generated based on Boolean operators for identification of the reference articles. 31 studies were included overall. Revision rate was lower in the cementless group compared to the cemented group (chi square=4.36, p=0.04), aseptic loosening was lesser in the cementless group compared to the cemented group (chi square=4.13, p=0.04). The type of the arthroplasty did not affect the infection rate (chi square=2.51, p=0.11), pre and post op Harris Hip Score showed statistically significant difference, but there was no difference between types of arthroplasty. We conclude that THA with uncemented components is better and provided lower revision and aseptic loosening when compared to cemented groups in patients with PDB

Aim. This study investigated the effect of the choice of antibiotic regime on outcome of patients treated for fracture-related infection (FRI) at 3 centres, in the UK and the Netherlands between 2015 and 2019. Method. All patients with FRI, confirmed by the FRI Consensus Definition. 1. and treated surgically, were included. Data were collected on patient characteristics, microbial cultures, antibiograms, empiric and definitive systemic antibiotic regimes and local antibiotic use. All patients were followed up for at least one year. The primary outcome was eradication of infection. The chosen antibiotic regimes were compared to the recent guidelines from the FRI Consensus Group. 2. , to assess the correlation with outcome. Results. 433 FRIs were treated in patients with mean age 49.7 years (range 14–84). Patients were followed up for a mean of 26 months (range 12–72). A microbiological diagnosis was obtained in 353 patients (18.5% culture negative rate), with 46% monomicrobial and 35.5% polymicrobial. Staph aureus was present in 51.3% of monomicrobial and 55.2% of polymicrobial infections. Negative cultures were much less likely in FRI within 10 weeks of injury (p=0.00001). Treatment failure with recurrent infection occurred in 13.6% of patients. Failure was more likely in culture positive cases (Polymicrobial; p=0.016, monomicrobial 0.039). Definitive antibiotic regimes were fully compliant with the FRI Guideline in 107 cases (24.7%). In 294 cases (68%) antibiotic regimes outside the guidelines were used. Non-compliance was often due to differences in recommended dosing or overtreatment with extra antimicrobials. 32 cases (7.4%) could not be assessed against the FRI Guidelines as the organisms or regimes were not represented in the guide. Failure rate with FRI Guideline compliant regimes was 12.1% and with non-compliant, 13.2% (p=0.87). Failure in unclassifiable cases was 21.9%. The use of local antibiotics reduced the recurrence rate from 18.3% without local antibiotics to 10.3% with local antibiotics (p=0.022). Conclusions. This study demonstrated that there can be considerable variability in the choice of antimicrobial regimes in FRI. Some deviations from the FRI Guideline did not result in poorer outcomes. These smaller differences in antimicrobial choice may not be major determinants of outcome

Introduction. There is little evidence surrounding the clinical implications of a diagnosis of IIa hip dysplasia with no consensus as to its efficacy as a predictor pathological dysplasia or treatment. Therefore, we evaluated the importance of categorising 2a hip dysplasia in to 2a- and 2a+ to better understand the clinical outcomes of each. Methods. A 9-year retrospective cohort study of patients with a diagnosis of type IIa hip dysplasia between 2011 – 2020 (n=341) in our centre. Ultrasound scans were graded using Graf's classification, assessment of management and DDH progression was completed through prospective data collection by the authors. Results. The prevalence of IIa hip dysplasia within our population was 6.7/1000 live births. There was significantly higher incidence of treatment in the IIa- (31.4%, n=17/54) group when compared to the 2a+ group (10%, n=28/287), (p<0.01). In those that had an abnormality (torticollis and/or foot abnormality) treatment rates (24% n=7/29) were significantly (p<0.05) higher than those without anatomical abnormality (15%, n=48/312). Conclusion. This study has demonstrated the significant clinical impact of a IIa- diagnosis on progression to pathological dysplasia and therefore higher rates of treatment in IIa- hips. Furthermore, we have demonstrated the importance of detection of IIa hips through a national screening program, to allow for timely intervention to prevent missing the acetabular maturation window. Therefore, it is our recommendation that all patients with additional anatomical abnormalities and those with a diagnosis of type IIa- hip dysplasia be considered for immediate treatment or urgent follow up following their diagnosis to prevent late conservative intervention

Introduction. The management of open long bone fractures is well described and has been standardised through a number of well-established guidelines. However, there is no consensus regarding the application of local antibiotics into the open fracture site as a means of reducing infection rates. Materials & Methods. A systematic review and meta-analysis were undertaken as per PRISMA guidelines. PROSPERO Registration CRD42022323545. PubMed, EMBASE, Scopus and CENTRAL were the databases assessed. The Newcastle Ottawa Scale and the Rob 2 Tool were used to assess bias. A qualitative synthesis of all included studies and meta-analysis of suitable subgroups was undertaken. Results. In total, 12 studies (11 observational, 1 RCT) assessing 2431 open fractures were included for analysis. All compared the addition of a local antibiotic therapy to a standard treatment versus the standard treatment alone. The methods of delivery were vancomycin powder (4 papers), tobramycin polymethylmethacrylate beads (4 papers), gentamicin coated intramedullary (IM) nails (2 papers), gentamicin injections (1 paper) and antibiotic released IM core cement (1 paper). The addition of vancomycin powder did not decrease infection rates in comparison to intravenous antibiotics alone (OR 1.3, 95% CI (0.75 – 2.26)). Antibiotic coated IM Nails appear to have an association with lower infection rates than standard IM Nails. PMMA antibiotics have shown varied results in reducing infection rates depending on the individual studies. Conclusions. There are numerous methods available to deliver antibiotics locally to an open fracture site. Further high-quality research is required to provide a definitive conclusion on their efficacy irrespective of delivery method

In reverse shoulder arthroplasty (RSA), a high complication rate is noted in the international literature (24.7%), and limited local literature is available. The complications in our developing health system, with high HIV, tuberculosis and metabolic syndrome prevalence may be different from that in developed health systems where the literature largely emanates from. The aim of this study is to describe the complications and complication rate following RSA in a South African cohort. An analytical, cross-sectional study was done where all patients’ who received RSA over an 11 year period at a tertiary hospital were evaluated. One-hundred-and-twenty-six primary RSA patients met the inclusion criteria and a detailed retrospective evaluation of their demographics, clinical variables and complication associated with their shoulder arthroplasty were assessed. All fracture, revision and tumour resection arthroplasties were excluded, and a minimum of 6 months follow up was required. A primary RSA complication rate of 19.0% (24/126) was noted, with the most complications occurring after 90 days at 54.2% (13/24). Instability was the predominant delayed complication at 61.5% (8/13) and sepsis being the most common in the early days at 45.5% (5/11). Haematoma formation, hardware failure and axillary nerve injury were also noted at 4.2% each (1/24). Keeping in mind the immense difference in socioeconomical status and patient demographics in a third world country the RSA complication rate in this study correlates with the known international consensus. This also proves that RSA is still a suitable option for rotator cuff arthropathy and glenohumeral osteoarthritis even in an economically constrained environment like South Africa

Currently, the consensus regarding subscapularis tendon repair during a reverse total shoulder arthroplasty (rTSA) is to do so if it is possible. Repair is thought to decrease the risk of dislocation and improve internal rotation but may also increase stiffness and improvement in internal rotation may be of subclinical benefit. Aim is to retrospectively evaluate the outcomes of rTSA, with or without a subscapularis tendon repair. We completed a retrospective review of 51 participants (25 without and 26 with subscapularis repair) who received rTSR by a single-surgeon using a single-implant. Three patient reported outcome measures (PROM) were assessed pre-operatively and post-operative at twelve months, as well as range of movement (ROM) and plain radiographs. Statistical analysis utilized unpaired t tests for parametric variables and Mann-Whitney U test for nonparametric variables. External Rotation ROM pre-operatively was the only variable with a significance difference (p=0.02) with the subscapularis tendon repaired group having a greater range. Pre- and post-operative abduction (p=0.72 & 0.58), forward flexion (p=0.67 & 0.34), ASES (p=0.0.06 & 0.78), Oxford (p=0.0.27 & 0.73) and post-operative external rotation (p=0.17). Greater external rotation ROM pre-operatively may be indicative of the ability to repair the subscapularis tendon intra-operatively. However, repair does not seem to improve clinical outcome at 12 months. There was no difference of the PROMs and AROMs between the subscapularis repaired and not repaired groups for any of the variables at the pre-operative or 12 month post operative with the exception of the external rotation ROM pre-operatively. We can conclude that from PROM or AROM perspective there is no difference if the tendon is repaired or not in a rTSR and indeed the patients without the repair may have improved outcomes at 12 months

The Latarjet procedure is a well described method to stabilize anterior shoulder instability. There are concerns of high complication rates, one of these being a painful shoulder without instability due to screw irritation. The arthroscopic changes in the shoulder at time of screw removal compared to those pre-Latarjet have not been described in the literature. We conducted a retrospective review of arthroscopic videos between 2015 and 2022 of 17 patients at the time of their Latarjet screw removal and where available (n=13) compared them to arthroscopic findings at time of index Latarjet. Instability was an exclusion criterion. X-rays prior to screw removal were assessed independently by two observers blinded to patient details for lysis of the graft. Arthroscopic assessment of the anatomy and pathological changes were made by two shoulder surgeons via mutual consensus. An intraclass correlation coefficient (ICC) was analyzed as a measure for the inter-observer reliability for the radiographs. Our cohort had an average age of 21.5±7.7 years and an average period of 16.2±13.1 months between pre- and post-arthroscopy. At screw removal all patients had an inflamed subscapularis muscle with 88% associated musculotendinous tears and 59% had a pathological posterior labrum. Worsening in the condition of subscapularis muscle (93%), humeral (31%) and glenoid (31%) cartilage was found when compared to pre-Latarjet arthroscopes. Three failures of capsular repair were seen, two of these when only one anchor was used. X-ray review demonstrated 79% of patients had graft lysis. Excellent inter-rater reliability was observed with an ICC value of 0.82. Our results show a high rate of pathological change in the subscapularis muscle, glenoid labrum and articular cartilage in the stable but painful Latarjet. 79% of patients had graft lysis with prominent screws on X-ray

Classifying trochlear dysplasia (TD) is useful to determine the treatment options for patients suffering from patellofemoral instability (PFI). There is no consensus on which classification system is more reliable and reproducible for this purpose to guide clinicians in order to treat PFI. There are also concerns about validity of the Dejour classification (DJC), which is the most widely used classification for TD, having only a fair reliability score. The Oswestry-Bristol classification (OBC) is a recently proposed system of classification of TD and the authors report a fair-to-good interobserver agreement and good-to-excellent intra-observer agreement in the assessment of TD. The aim of this study was to compare the reliability and reproducibility of these two classifications. 6 assessors (4 consultants and 2 registrars) independently evaluated 100 magnetic resonance axial images of the patella-femoral joint for TD and classified them according to OBC and DJC. These assessments were again repeated by all raters after 4 weeks. The inter and intra-observer reliability scores were calculated using Cohen's kappa and Cronbach's alpha. Both classifications showed good to excellent interobserver reliability with high alpha scores. The OBC classification showed a substantial intra-observer agreement (mean kappa 0.628)[p<0.005] whereas the DJC showed a moderate agreement (mean kappa 0.572) [p<0.005]. There was no significant difference in the kappa values when comparing the assessments by consultants to those by registrars, in either classification systems. This large study from a non-founding institute shows both classification systems to be reliable for classifying TD based on magnetic resonance axial images of the patella-femoral joint, with the simple to use OBC having a higher intra-observer reliability score compared to the DJC

Introduction. Fracture related infection (FRI) is a challenging complication to manage in an orthoplastic setting. Consensus guidelines have been created to standardise the diagnosis of FRI and comprise confirmatory and suggestive criteria. In this study, the aim is to assess the diagnostic criteria and management of FRI with a particular focus on soft tissue reconstruction. Materials & Methods. A retrospective study to identify the outcomes of FRI in the lower limb over a five year period at a Major Trauma Centre. Fracture specific information that was analysed includes: open versus closed, fractured bone(s) and site, initial fracture management, method of diagnosis and soft tissue management. Results. A total of 40 patients were identified, 80% of whom were male (n= 32). The mean age for FRI diagnosis was 54 years (range 18–83 years). In our patient cohort, 10% were immunosuppressed and another 12.5% had a formal diagnosis of Diabetes Mellitus. A diagnosis of acute FRI (i.e. < six weeks from time of injury) was made in 9 patients (22.5%). Chronic FRI was noted in 25 patients (62.5%). There was equal incidence of FRI in patients with closed fractures and open fractures (42.5%). Tibia and fibula fractures were most common (87.5%, n=35). Regardless of fractured bone(s), the more distal the fracture the higher the incidence of FRI (60% distal versus 12.5% proximal). Gram-positive cocci were the most commonly identified pathogens, identified in 25% of patients. Five patients underwent free flap reconstruction, two patients received pedicled muscle flaps and another two patients received split thickness skin grafts. Conclusions. The diagnosis of FRI can be confirmed through the presence of a combination of confirmatory and suggestive criteria. We advocate a staged approach in the management of FRI with radical wound excision and temporary coverage followed by definitive soft tissue reconstruction

Introduction. Knee arthrodesis is a useful limb salvage technique to maintain function in patients with complex and infected total knee arthroplasties (TKA). There are a number of commonly used external fixators, but no consensus on which of these are optimal. The aim of this study was to synthesise the current literature to guide clinical decision making and improve patient outcomes. We systematically review the literature to compare outcomes of external fixators in arthrodesis following infected TKA. Materials & Methods. A systematic review of the literature of primary research articles investigating the use of external fixators for knee arthrodesis after an infected TKA was conducted. Relevant articles were identified with a search strategy on online databases (EMBASE and Medline) and reviewed by two independent reviewers. Clinical outcome measures were independently extracted by two reviewers which included union rate, infection eradication rate, complication rate, time to fusion, and time in frame. Results. Circular frames were more likely to result in union compared to biplanar (OR 1.40 p=0.456) and monoplanar frames (OR 2.28 p=0.018). Infection recurrence was least likely in those treated by circular frames when compared to monoplanar (OR 0.12 p=0.005) and biplanar external fixators (0.41 P=0.331). Complication rates were highest in the circular fixator group, followed by the monoplanar fixator group and biplanar fixator group at 34%, 31% and 11% respectively. Conclusions. Analysis of the available literature suggests higher union and infection eradication rates with circular frames over the other two fixation methods despite a higher complication rate. There is a paucity in the literature and therefore, no firm conclusions can be drawn. Further research investigating the variations and biomechanical properties between different external fixation methods for knee arthrodesis is necessary. Further clarity in reporting and pooled data would be useful for future analysis
