The National Joint Registry Data Quality Audit of elbow arthroplastyAims: The aim of this audit was to assess and improve the completeness and accuracy of the National Joint Registry (NJR) dataset for arthroplasty of the elbow. Methods: It was performed in two phases. In Phase 1, the completeness was assessed by comparing the NJR elbow dataset with the NHS England Hospital Episode Statistics (HES) data between April 2012 and April 2020. In order to assess the accuracy of the data, the components of each arthroplasty recorded in the NJR were compared to the type of arthroplasty which was recorded. In Phase 2, a national collaborative audit was undertaken to evaluate the reasons for unmatched data, add missing arthroplasties, and evaluate the reasons for the recording of inaccurate arthroplasties and correct them. Results: Phase 1 identified 5,539 arthroplasties in HES which did not match an arthroplasty on the NJR, and 448 inaccurate arthroplasties from 254 hospitals. Most mismatched procedures (3,960 procedures; 71%) were radial head arthroplasties (RHAs). In Phase 2, 142 NHS hospitals with 3,640 (66%) mismatched and 314 (69%) inaccurate arthroplasties volunteered to assess their records. A large proportion of the unmatched data (3,000 arthroplasties; 82%) were confirmed as being missing from the NJR. The overall rate of completeness of the NJR elbow dataset improved from 63% to 83% following phase 2, and the completeness of total elbow arthroplasty data improved to 93%. Missing RHAs had the biggest impact on the overall completeness, but through the audit the number of RHAs in the NJR nearly doubled and completeness increased from 35% to 70%. The accuracy of data was 94% and improved to 98% after correcting 212 of the 448 inaccurately recorded arthroplasties. Conclusion: The rate of completeness of the NJR total elbow arthroplasty dataset is currently 93% and the accuracy is 98%. This audit identified challenges of data capture with regard to RHAs. Collaboration with a trauma and orthopaedic trainees through the British Orthopaedic Trainee Association improved the completeness and accuracy of the NJR elbow dataset, which will improve the validity of the reports and of the associated research.

Impact of COVID-19 on clinical outcomes for patients with fractured hip: a multicentre observational cohort studyAims: There are reports of a marked increase in perioperative mortality in patients admitted to hospital with a fractured hip during the COVID-19 pandemic in the UK, USA, Spain, and Italy. Our study aims to describe the risk of mortality among patients with a fractured neck of femur in England during the early stages of the COVID-19 pandemic. Methods: We completed a multicentre cohort study across ten hospitals in England. Data were collected from 1 March 2020 to 6 April 2020, during which period the World Health Organization (WHO) declared COVID-19 to be a pandemic. Patients ≥ 60 years of age admitted with hip fracture and a minimum follow-up of 30 days were included for analysis. Primary outcome of interest was mortality at 30 days post-surgery or postadmission in nonoperative patients. Secondary outcomes included length of hospital stay and discharge destination. Results: In total, 404 patients were included for final analysis with a COVID-19 diagnosis being made in 114 (28.2%) patients. Overall, 30-day mortality stood at 14.4% (n = 58). The COVID-19 cohort experienced a mortality rate of 32.5% (37/114) compared to 7.2% (21/290) in the non-COVID cohort (p < 0.001). In adjusted analysis, 30-day mortality was greatest in patients who were confirmed to have COVID-19 (odds ratio (OR) 5.64, 95% confidence interval (CI) 2.95 to 10.80; p < 0.001) with an adjusted excess risk of 20%, male sex (OR 2.69, 95% CI 1.37 to 5.29; p = 0.004) and in patients with ≥ two comorbidities (OR 4.68, CI 1.5 to 14.61; p = 0.008). Length of stay was also extended in the COVID-19 cohort, on average spending 17.6 days as an inpatient versus 12.04 days in the non-COVID-19 group (p < 0.001). Conclusion: This study demonstrates that patients who sustain a neck of femur fracture in combination with COVID-19 diagnosis have a significantly higher risk of mortality than would be normally expected.Cite this article: Bone Joint Open 2020;1-11:697-705.

Treatment of supracondylar periprosthetic femoral fractures with retrograde intramedullary nailing versus distal femoral plating: A systematic review and meta-analysis of current evidenceBackground: Supracondylar periprosthetic fractures, when amenable to fixation, can be treated by either retrograde intramedullary nailing (RIMN) or plating. There is paucity of evidence regarding the superiority of one fixation method over the other. This review aims to determine which fixation method leads to better functional outcomes and perioperative complications. Hypothesis: Superiority of intramedullary nailing in terms of fracture healing and surgical complications when compared to distal femoral plating. Materials and methods: Using PRISMA guidelines, a systematic search was performed. Studies which reported comparative outcome data following the two interventions were included. Qualitative data analysis and narrative synthesis were reported. Pooled comparisons were conducted when similar quantifiable outcomes were reported in a minimum of three studies. Results: A total of 151 records were generated by the search. Eight studies met the eligibility criteria so were included in the final analysis. The studies comprised a total of 407 cases, with a follow up period ranging from 1 to 15 years. 252 cases were treated with plate fixation and 155 with RIMN. All studies were mitigated by heterogeneity and methodological limitations. The review showed marked variation in descriptive fracture classifications. Narrative data synthesis was conducted. Although guarded by the methodological limitations of individual studies, outcomes showed that mean time to union was equivalent; 5.88 months for RIMN compared to 6.75 months in plating, standardised mean difference=0.28 (95% CI -0.02-0.58). Similarly, no statistically significant differences were reported between RIMN and plating for deep infection (OR:1.41 95%CI 0.40-5.00) and revision surgery (OR: 0.74, 95%CI 0.39-1.41). Discussion: Clinical outcomes showed a tendency that favours intramedullary nailing; however, generalisation of results was not possible. Future priority must be awarded to higher quality research in the form of a collaborative multicentre observational studies to delineate appropriate major diagnostic categories, ultimately informing a large comparative trial using condition specific validated outcome measures.

Tönnis angle and acetabular depth ratio: predictors of dislocation following hemiarthroplasty for hip fracture.35 cases of dislocation were identified and 140 random controls were selected. Cases of dislocation had a larger mean TA (8.8° vs. 5.5°, p < 0.001) and lower mean ADR (254 vs. 289, p < 0.001) than controls. 20 out of 35 (57%) cases were considered to have abnormal acetabular morphology, compared to 19 out of 140 (14%) controls. The odds of dislocation is 8.5 times greater (odds ratio = 8.49, 95%CI = 3.73, 19.39) in patients with abnormal TA and/or ADR.

Surgical fixation with K-wires versus casting in adults with fracture of distal radius : DRAFFT2 multicentre randomised clinical trialObjective: To assess wrist function, quality of life, and complications in adult patients with a dorsally displaced fracture of the distal radius, treated with either a moulded cast or surgical fixation with K-wires. Design: Multicentre randomised clinical superiority trial, SETTING: 36 hospitals in the UK National Health Service (NHS). Participants: 500 adults aged 16 or over with a dorsally displaced fracture of the distal radius, randomised after manipulation of their fracture (255 to moulded cast; 245 to surgical fixation). Interventions: Manipulation and moulded cast was compared with manipulation and surgical fixation with K-wires plus cast. Details of the application of the cast and the insertion of the K-wires were at the discretion of the treating surgeon, according to their normal clinical practice. Main outcome measures: The primary outcome measure was the Patient Rated Wrist Evaluation (PRWE) score at 12 months (five questions about pain and 10 about function and disability; overall score out of 100 (best score=0 and worst score=100)). Secondary outcomes were PRWE score at three and six months, quality of life, and complications, including the need for surgery due to loss of fracture position in the first six weeks. Results: The mean age of participants was 60 years and 417 (83%) were women; 395 (79%) completed follow-up. No statistically significant difference in the PRWE score was seen at 12 months (cast group (n=200), mean 21.2 (SD 23.1); K-wire group (n=195), mean 20.7 (22.3); adjusted mean difference -0.34 (95% confidence interval -4.33 to 3.66), P=0.87). No difference was seen at earlier time points. In the cast group, 33 (13%) of participants needed surgical fixation for loss of fracture position in the first six weeks compared with one revision surgery in the K-wire group (odds ratio 0.02, 95% confidence interval 0.001 to 0.10). Conclusions: Among patients with a dorsally displaced distal radius fracture that needed manipulation, surgical fixation with K-wires did not improve patients' wrist function at 12 months compared with a cast.

Orthopaedic trauma hospital outcomes - patient operative delays (ORTHOPOD) Study : the management of day-case orthopaedic trauma in the United KingdomIntroduction: ORTHOPOD: Day Case Trauma is a multicentre prospective service evaluation of day-case trauma surgery across four countries. It is an epidemiological assessment of injury burden, patient pathways, theatre capacity, time to surgery and cancellation. It is the first evaluation of day-case trauma processes and system performance at nationwide scale. Methods: Data was prospectively recorded through a collaborative approach. Arm one captured weekly caseload burden and operating theatre capacity. Arm two detailed patient and injury demographics, and time to surgery for specific injury groups. Patients scheduled for surgery between 22/08/22 and 16/10/22 and operated on before 31/10/22, were included. For this analysis, hand and spine injuries were excluded. Results: Data was obtained from 86 Data Access Groups (70 in England, 2 in Wales, 10 in Scotland and 4 in Northern Ireland). After exclusions, 709 weeks worth of data representing 23,138 operative cases were analysed. Day-case trauma patients (DCTP) accounted for 29.1% of overall trauma burden and utilised 25.7% of general trauma list capacity. They were predominantly adults aged 18 to 59 (56.7%) with upper limb Injuries (65.7%). Across the four nations, the median number of day-case trauma lists (DCTL) available per week was 0 (IQR 1). 6 of 84 (7.1%) hospitals had at least five DCTLs per week. Rates of cancellation (13.2% day-case; 11.9% inpatient) and escalation to elective operating lists (9.1% day-case; 3.4% inpatient) were higher in DCTPs. For equivalent injuries, DCTPs waited longer for surgery. Distal radius and ankle fractures had median times to surgery within national recommendations: 3 days and 6 days respectively. Outpatient route to surgery was varied. Dominant pathways (>50% patients listed at that episode) in England and Wales were uncommon but the most frequently seen was listing patients in the emergency department, 16 of 80 hospitals (20%). Conclusion: There is significant mismatch in DCTP management and resource availability. There is also considerable variation in DCTP route to surgery. Suitable DCTL patients are often managed as inpatients. Improving day-case trauma services reduces the burden on general trauma lists and this study demonstrates there is considerable scope for service and pathway development and improved patient experience.

Characteristics and risk factors of UCS fracture subtypes in periprosthetic fractures around the hipAims: Periprosthetic fractures (PPFs) following hip arthroplasty are complex injuries. This study evaluates patient demographic characteristics, management, outcomes, and risk factors associated with PPF subtypes over a decade. Methods: Using a multicentre collaborative study design, independent of registry data, we identified adults from 29 centres with PPFs around the hip between January 2010 and December 2019. Radiographs were assessed for the Unified Classification System (UCS) grade. Patient and injury characteristics, management, and outcomes were compared between UCS grades. A multinomial logistic regression was performed to estimate relative risk ratios (RRR) of variables on UCS grade. Results: A total of 1,104 patients were included. The majority were female (57.9%; n = 639), ethnically white (88.5%; n = 977), used mobility aids (67%; n = 743), and had a median age of 82 years (interquartile range (IQR) 74 to 87). A total of 77 (7%) had pain prior to the PPF. The most common UCS grade was B2 (33%; n = 368). UCS type D fractures had the longest length of stay (median 19 days (IQR 11 to 26)), highest readmission to hospital (21%; n = 9), and highest rate of discharge to step-down care (52%; n = 23). Multinomial regression suggests that uncemented femoral stems are associated with a reduced risk of UCS C (RRR 0.36 (95% confidence interval (CI) 0.2 to 0.7); p = 0.002) and increased risk of UCS A (RRR 3.3 (95% CI 1.9 to 5.7); p < 0.001), compared to UCS B fracture. Conclusion: The most common PPF type in elderly frail patients is UCS B2. Uncemented stems have a lower risk of UCS C fractures compared to cemented stems. A national PPF database is needed to further identify correlation between implants and fracture subtypes.

Novel suture/suture-anchor fixation versus tension band wiring for olecranon fractures: A systematic review.Eighteen studies were included, nine of which involved SF/SAF (99 patients) and nine TBW (382 patients). SF/SAF techniques were associated with lower rates of fracture/implant displacement (2% versus 9.7%, p = 0.01), implant irritation (1% versus 30.1%, p < 0.001) and overall complications (8% versus 46.1%, p < 0.001) when compared to TBW. Reoperation rates were lower for SF/SAF (3% versus 37.2%, p < 0.001). Total flexion/extension arc achieved was similar (130.16 ± 2.11 versus 129.45 ± 0.93 degrees). On average, patients regained a functional arc of flexion (135.21 ± 4.81 TBW versus 131.32 ± 12.99 SF/SAF) and extension (1.16 ± 7.54 SF/SAF versus 5.76 ± 7.98 TBW).

Five-year outcomes for patients with a displaced fracture of the distal tibiaAims: To report the outcomes of patients with a fracture of the distal tibia who were treated with intramedullary nail versus locking plate in the five years after participating in the Fixation of Distal Tibia fracture (FixDT) trial. Methods: The FixDT trial reported the results for 321 patients randomized to nail or locking plate fixation in the first 12 months after their injury. In this follow-up study, we report the results of 170 of the original participants who agreed to be followed up until five years. Participants reported their Disability Rating Index (DRI) and health-related quality of life (EuroQol five-dimension three-level questionnaire) annually by self-reported questionnaire. Further surgical interventions related to the fracture were also recorded. Results: There was no evidence of a difference in patient-reported disability, health-related quality of life, or the need for further surgery between participants treated with either type of fixation at five years. Considering the combined results for all participants, there was no significant change in DRI scores after the first 12 months of follow-up (difference between 12 and 24 months, 3.3 (95% confidence interval -1.8 to 8.5); p = 0.203), with patients reporting around 20% disability at five years. Conclusion: This study shows that the moderate levels of disability and reduced quality of life reported by participants 12 months after a fracture of the distal tibia persist in the medium term, with little evidence of improvement after the first year.

Exploring the Roles and Responsibilities of an Educational Supervisor in Medical Training Within the United Kingdom.Medical trainees or junior doctors within the United Kingdom, regardless of their level of training or specialty, are assigned an educational supervisor (ES). The General Medical Council within the United Kingdom defines an ES as "a trainer who is selected and appropriately trained to be responsible for the overall supervision and management of a specified trainee's educational progress during a clinical placement or series of placements." This article critically evaluates the current literature to explore the roles of the ES in supporting and monitoring a trainee's progress while discussing challenges associated with the role. Through clearer delineation of the role of an ES, barriers to improving training can be identified and overcome, thus improving overall satisfaction with training.

Risk factors associated with revision for prosthetic joint infection following knee replacement: an observational cohort study from England and Wales.Of 679 010 primary knee replacements done between 2003 and 2013 in England and Wales, 3659 were subsequently revised for an indication of prosthetic joint infection between 2003 and 2014, after a median follow-up of 4·6 years (IQR 2·6-6·9). Male sex (rate ratio [RR] for male vs female patients 1·8 [95% CI 1·7-2·0]), younger age (RR for age ≥80 years vs <60 years 0·5 [0·4-0·6]), higher American Society of Anaesthesiologists [ASA] grade (RR for ASA grade 3-5 vs 1, 1·8 [1·6-2·1]), elevated body-mass index (BMI; RR for BMI ≥30 kg/m2vs <25 kg/m2 1·5 [1·3-1·6]), chronic pulmonary disease (RR 1·2 [1·1-1·3]), diabetes (RR 1·4 [1·2-1·5]), liver disease (RR 2·2 [1·6-2·9]), connective tissue and rheumatic diseases (RR 1·5 [1·3-1·7]), peripheral vascular disease (RR 1·4 [1·1-1·7]), surgery for trauma (RR 1·9 [1·4-2·6]), previous septic arthritis (RR 4·9 [2·7-7·6]) or inflammatory arthropathy (RR 1·4 [1·2-1·7]), operation under general anaesthesia (RR 1·1 [1·0-1·2]), requirement for tibial bone graft (RR 2·0 [1·3-2·7]), use of posterior stabilised fixed bearing prostheses (RR for posterior stabilised fixed bearing prostheses vs unconstrained fixed bearing prostheses 1·4 [1·3-1·5]) or constrained condylar prostheses (3·5 [2·5-4·7]) were associated with a higher risk of revision for prosthetic joint infection. However, uncemented total, patellofemoral, or unicondylar knee replacement (RR for uncemented vs cemented total knee replacement 0·7 [95% CI 0·6-0·8], RR for patellofemoral vs cemented total knee replacement 0·3 [0·2-0·5], and RR for unicondylar vs cemented total knee replacement 0·5 [0·5-0·6]) were associated with lower risk of revision for prosthetic joint infection. Most of these factors had time-specific effects, depending on the time period post-surgery.

ARthroscopy in Knee OsteoArthritis (ARK-OA): a multicentre study assessing compliance to national guidelinesIntroduction: The use of arthroscopy to alleviate the symptoms of osteoarthritis has been questioned by recent high quality evidence. This has led to the development of guidelines by specialist and national bodies advocating against its use. Aims: To examine the trends of the rates of arthroscopy in patients with knee osteoarthritis over the past five years and determining compliance with guidelines. Methods: Multi-centre, retrospective audit in five hospital trusts in the United Kingdom. The number of arthroscopies performed by month from 2013 to 2017 was identified through hospital coding. Fifty randomly selected records from the year 2017 were further analysed to assess compliance with NICE guidelines. Results: Between 2013 and 2017, the number of arthroscopies performed annually in five trusts dropped from 2028 to 1099. In the year 2017, 17.7% of patients with no mechanical symptoms and moderate-to-severe arthritis pre-operatively had arthroscopy. Conclusion: Knee arthroscopy continues to be used as a treatment for osteoarthritis, against national guidelines. Whilst overall numbers are declining, further interventions, including implementation of high-quality conservative care is required to further eliminate unnecessary procedures.

High degree of consensus amongst an expert panel regarding focal resurfacing of chondral and osteochondral lesions of the femur with mini-implants.Introduction: The rationale for the use of mini-implants for partial resurfacing in the treatment of femoral chondral and osteochondral lesions is still under debate. The evidence supporting best practise guidelines is based on studies with low-level evidence. A consensus group of experts was convened to collaboratively advance towards consensus opinions regarding the best available evidence. The purpose of this article is to report the resulting consensus statements. Methods: Twenty-five experts participated in a process based on the Delphi method of achieving consensus. Questions and statements were drafted via an online survey of two rounds, for initial agreement and comments on the proposed statements. An in-person meeting between the panellists was organised during the 2022 ESSKA congress to further discuss and debate each of the statements. A final agreement was made via a final online survey a few days later. The strength of consensus was characterised as: consensus, 51-74% agreement; strong consensus, 75-99% agreement; unanimous, 100% agreement. Results: Statements were developed in the fields of patient assessment and indications, surgical considerations and postoperative care. Between the 25 statements that were discussed by this working group, 18 achieved unanimous, whilst 7 strong consensus. Conclusion: The consensus statements, derived from experts in the field, represent guidelines to assist clinicians in decision-making for the appropriate use of mini-implants for partial resurfacing in the treatment of femoral chondral and osteochondral lesions

Outcomes of revision total hip arthroplasty using a vascularised anterior femoral windowPurpose: Extraction of the distal femoral cement mantle and restrictor during revision total hip arthroplasty (rTHA) is challenging and can compromise host bone stock. The aim of this study is to report outcomes of our femoral windowing technique for cement removal. Methods: We report on a cohort of 36 patients with an average age of 68.7 years who underwent 40 cemented rTHA between 2011 and 2017 using a vascularised anterior femoral window. Clinical and radiological outcomes were retrospectively reviewed with a mean follow-up of 6.6 years (range, 3.8-10). Results: Latest mean WOMAC score was 25.4 and all windows achieved radiographic union by a mean of 7.9 weeks. Femoral component survivorship was 100% and 38 out of 40 rTHAs showed no evidence of radiological loosening. Conclusion: The vascularised anterior window to remove the distal femoral cement mantle under direct vision is safe and reproducible with excellent clinical and radiographic results.
