Aims. The principles of evidence-based medicine (EBM) are the foundation of modern medical practice. Surgeons are familiar with the commonly used statistical techniques to test hypotheses, summarize findings, and provide answers within a specified range of probability. Based on this knowledge, they are able to critically evaluate research before deciding whether or not to adopt the findings into practice. Recently, there has been an increased use of artificial intelligence (AI) to analyze information and derive findings in orthopaedic research. These techniques use a set of statistical tools that are increasingly complex and may be unfamiliar to the orthopaedic surgeon. It is unclear if this shift towards less familiar techniques is widely accepted in the orthopaedic community. This study aimed to provide an exploration of understanding and acceptance of AI use in research among orthopaedic surgeons. Methods. Semi-structured in-depth interviews were carried out on a sample of 12 orthopaedic surgeons. Inductive thematic analysis was used to identify key themes. Results. The four intersecting themes identified were: 1) validity in traditional research, 2) confusion around the definition of AI, 3) an inability to validate AI research, and 4) cautious optimism about AI research. Underpinning these themes is the notion of a validity heuristic that is strongly rooted in traditional research teaching and embedded in medical and surgical training. Conclusion. Research involving AI sometimes challenges the accepted traditional evidence-based framework. This can give rise to confusion among orthopaedic surgeons, who may be unable to confidently validate findings. In our study, the impact of this was mediated by cautious optimism based on an ingrained validity heuristic that orthopaedic surgeons develop through their medical training. Adding to this, the integration of AI into everyday life works to reduce suspicion and aid acceptance. Cite this article: Bone Jt Open 2023;4(9):696–703

Aims. Diabetic foot care is a significant burden on the NHS in England. We have conducted a nationwide survey to determine the current participation of orthopaedic surgeons in diabetic foot care in England. Methods. A questionnaire was sent to all 136 NHS trusts audited in the 2018 National Diabetic Foot Audit (NDFA). The questionnaire asked about the structure of diabetic foot care services. Results. Overall, 123 trusts responded, of which 117 admitted patients with diabetic foot disease and 113 had an orthopaedic foot and ankle surgeon. A total of 90 trusts (77%) stated that the admission involved medicine, with 53 (45%) of these admissions being exclusively under medicine, and 37 (32%) as joint admissions. Of the joint admissions, 16 (14%) were combined with vascular and 12(10%) with orthopaedic surgery. Admission is solely under vascular surgery in 12 trusts (10%) and orthopaedic surgery in 7 (6%). Diabetic foot abscesses were drained by orthopaedic surgeons in 61 trusts (52%) and vascular surgeons in 47 (40%). Conclusion. Orthopaedic surgeons make a significant contribution to both acute and elective diabetic foot care currently in the UK. This contribution is likely to increase with the movement of vascular surgery to a hub and spoke model, and measures should be put in place to increase the team based approach to the diabetic foot, for example with the introduction of a best practice tariff.

Aims. Medical comorbidities are a critical factor in the decision-making process for operative management and risk-stratification. The Hierarchical Condition Categories (HCC) risk adjustment model is a powerful measure of illness severity for patients treated by surgeons. The HCC is utilized by Medicare to predict medical expenditure risk and to reimburse physicians accordingly. HCC weighs comorbidities differently to calculate risk. This study determines the prevalence of medical comorbidities and the average HCC score in Medicare patients being evaluated by neurosurgeons and orthopaedic surgeon, as well as a subset of academic spine surgeons within both specialities, in the USA. Methods. The Medicare Provider Utilization and Payment Database, which is based on data from the Centers for Medicare and Medicaid Services’ National Claims History Standard Analytic Files, was analyzed for this study. Every surgeon who submitted a valid Medicare Part B non-institutional claim during the 2013 calendar year was included in this study. This database was queried for medical comorbidities and HCC scores of each patient who had, at minimum, a single office visit with a surgeon. This data included 21,204 orthopaedic surgeons and 4,372 neurosurgeons across 54 states/territories in the USA. Results. Orthopaedic surgeons evaluated patients with a mean HCC of 1.21, while neurosurgeons evaluated patients with a mean HCC of 1.34 (p < 0.05). The rates of specific comorbidities in patients seen by orthopaedic surgeons/neurosurgeons is as follows: Ischemic heart disease (35%/39%), diabetes (31%/33%), depression (23%/31%), chronic kidney disease (19%/23%), and heart failure (17%/19%). Conclusion. Nationally, comorbidity rate and HCC value for these Medicare patients are higher than national averages for the US population, with ischemic heart disease being six-times higher, diabetes two-times higher, depression three- to four-times higher, chronic kidney disease three-times higher, and heart failure nine-times higher among patients evaluated by orthopaedic surgeons and neurosurgeons.

The coronavirus disease 2019 (COVID-19) pandemic has led to unprecedented challenges to healthcare systems worldwide. Orthopaedic departments have adopted business continuity models and guidelines for essential and non-essential surgeries to preserve hospital resources as well as protect patients and staff. These guidelines broadly encompass reduction of ambulatory care with a move towards telemedicine, redeployment of orthopaedic surgeons/residents to the frontline battle against COVID-19, continuation of education and research through web-based means, and cancellation of non-essential elective procedures. However, if containment of COVID-19 community spread is achieved, resumption of elective orthopaedic procedures and transition plans to return to normalcy must be considered for orthopaedic departments. The COVID-19 pandemic also presents a moral dilemma to the orthopaedic surgeon considering elective procedures. What is the best treatment for our patients and how does the fear of COVID-19 influence the risk-benefit discussion during a pandemic? Surgeons must deliberate the fine balance between elective surgery for a patient’s wellbeing versus risks to the operating team and utilization of precious hospital resources. Attrition of healthcare workers or Orthopaedic surgeons from restarting elective procedures prematurely or in an unsafe manner may render us ill-equipped to handle the second wave of infections. This highlights the need to develop effective screening protocols or preoperative COVID-19 testing before elective procedures in high-risk, elderly individuals with comorbidities. Alternatively, high-risk individuals should be postponed until the risk of nosocomial COVID-19 infection is minimal. In addition, given the higher mortality and perioperative morbidity of patients with COVID-19 undergoing surgery, the decision to operate must be carefully deliberated. As we ramp-up elective services and get “back to business” as orthopaedic surgeons, we have to be constantly mindful to proceed in a cautious and calibrated fashion, delivering the best care, while maintaining utmost vigilance to prevent the resurgence of COVID-19 during this critical transition period.

Aims. The Single Assessment Numerical Evalution (SANE) score is a pragmatic alternative to longer patient-reported outcome measures (PROMs). The purpose of this study was to investigate the concurrent validity of the SANE and hip-specific PROMs in a generalized population of patients with hip pain at a single timepoint upon initial visit with an orthopaedic surgeon who is a hip preservation specialist. We hypothesized that SANE would have a strong correlation with the 12-question International Hip Outcome Tool (iHOT)-12, the Hip Outcome Score (HOS), and the Hip disability and Osteoarthritis Outcome Score (HOOS), providing evidence for concurrent validity of the SANE and hip-specific outcome measures in patients with hip pain. Methods. This study was a cross-sectional retrospective database analysis at a single timepoint. Data were collected from 2,782 patients at initial evaluation with a hip preservation specialist using the iHOT-12, HOS, HOOS, and SANE. Outcome scores were retrospectively analyzed using Pearson correlation coefficients. Results. Mean raw scores were iHOT-12 67.01 (SD 29.52), HOS 58.42 (SD 26.26), HOOS 86.85 (SD 32.94), and SANE 49.60 (SD 27.92). SANE was moderately correlated with the iHOT-12 (r = -0.4; 95% CI -0.35 to -0.44; p < 0.001), HOS (r = 0.57; 95% CI 0.53 to 0.60; p < 0.001), and HOOS (r = -0.55; 95% CI -0.51 to -0.58; p < 0.001). The iHOT-12 and HOOS were recorded as a lower score, indicating better function, which accounts for the negative r values. Conclusion. This study was the first to investigate the relationship between the SANE and the iHOT-12, HOS, and HOOS in a population of patients with hip pain at the initial evaluation with an orthopaedic surgeon, and found moderate correlation between SANE and the iHOT-12, HOS, and HOOS. The SANE may be a pragmatic alternative for clinical benchmarking in a general population of patients with hip pain. The construct validity of the SANE should be questioned compared to legacy measures whose content validity has been more rigorously investigated. Cite this article: Bone Jt Open 2024;5(10):904–910

Aims. The aim of this study was to investigate surgeons’ reported change of treatment preference in response to the results and conclusion from a randomized contolled trial (RCT) and to study patterns of change between subspecialties and nationalities. Methods. Two questionnaires were developed through the Delphi process for this cross-sectional survey of surgical preference. The first questionnaire was sent out before the publication of a RCT and the second questionnaire was sent out after publication. The RCT investigated repair or non-repair of the pronator quadratus (PQ) muscle during volar locked plating of distal radial fractures (DRFs). Overall, 380 orthopaedic surgeons were invited to participate in the first questionnaire, of whom 115 replied. One hundred surgeons were invited to participate in the second questionnaire. The primary outcome was the proportion of surgeons for whom a treatment change was warranted, who then reported a change of treatment preference following the RCT. Secondary outcomes included the reasons for repair or non-repair, reasons for and against following the RCT results, and difference of preferred treatment of the PQ muscle between surgeons of different nationalities, qualifications, years of training, and number of procedures performed per year. Results. Of the 100 surgeons invited for the second questionnaire, 74 replied. For the primary outcome, six of 32 surgeons (19%), who usually repaired the PQ muscle and therefore a change of treatment preference was warranted, reported a change of treatment preference based on the RCT publication. Of the secondary outcomes, restoring anatomy was the most common response for repairing the PQ muscle. Conclusion. The majority of the orthopaedic surgeons, where a change of treatment preference was warranted based on the results and conclusion of a RCT, did not report willingness to change their treatment preference.

Introduction: In 2005, 88 patients (19M/69 F, mean age 55) initially referred by their GP to a Consultant Orthopaedic Surgeon were seen by an Operative Podiatrist as a waiting list initiative. The mean delay between GP referral and clinic appointment was 632 days. The majority of patients were listed for a surgical procedure. The podiatrist left the Trust before any listed surgery was performed. The cohort was subsequently reviewed by a Consultant Orthopaedic Surgeon prior to surgical intervention, creating a unique opportunity to compare podiatric and orthopaedic input in one patient group. Materials & Methods: Casenotes and clinic correspondence were identified by merging clinic datasets & retrieved in 86/88 cases. Medical records and documentation of peripheral vascular status were examined as a standard of care. Correlation of surgical decision making was examined qualitatively. Results: Circulatory status was found to be documented in 0/58 (0%) records available for patients seen by the podiatrist and 70/74 (95%) seen by the orthopaedic surgeon respectively. Vascular investigation or referral was initiated by the orthopaedic surgeon in 8 patients listed for surgery by the podiatrist. The listed procedure was postponed or cancelled by the orthopaedic surgeon in a further 11 patients (5 medically unfit for listed surgery, 4 treated conservatively & 2 unable to obtain valid consent). No written or dictated contemporaneous records were made for 23/88 (26%) of index podiatric consultations. Clinically significant drug history was documented by the podiatrist in 1/13 (8%) cases recorded by the orthopaedic surgeon. Discussion: Reasonable correlation was observed between proposed surgical interventions for forefoot problems. Poor correlation was observed for mid- and/or hind foot problems. Avoidable adverse outcomes might have been anticipated in 19/88 (22%) patients listed for surgery by the Operative Podiatrist. Conclusion: The employment of unsupervised non-medical surgical practitioners in hospital based orthopaedic practice is not appropriate

Artificial intelligence and machine-learning analytics have gained extensive popularity in recent years due to their clinically relevant applications. A wide range of proof-of-concept studies have demonstrated the ability of these analyses to personalize risk prediction, detect implant specifics from imaging, and monitor and assess patient movement and recovery. Though these applications are exciting and could potentially influence practice, it is imperative to understand when these analyses are indicated and where the data are derived from, prior to investing resources and confidence into the results and conclusions. In this article, we review the current benefits and potential limitations of machine-learning for the orthopaedic surgeon with a specific emphasis on data quality

Although most uncomplicated paediatric fractures do not require routine long-term follow-up with an orthopaedic surgeon, practitioners with limited experience dealing with paediatrics fractures will often defer to a strategy of unnecessary frequent clinical and radiographic follow-up. Development of an evidence-based clinical care pathway may help reduce unnecessary radiation exposure to this patient population and reduce costs to patient families and the healthcare system. A retrospective analysis including patients who presented to SickKids hospital between October 2009 and October 2014 for management of clavicle fractures was performed. Patients with previous clavicle fractures, perinatal injury, multiple fractures, non-accidental injury, underlying bone disease, sternoclavicular dislocations, fractures of the medial clavicular physis and fractures that were managed at external hospitals were excluded from the analysis. Variables including age, gender, previous injury, fracture laterality, mechanism of injury, polytrauma, surgical intervention and complications and number of clinic visits were recorded for all patients. Radiographs were analysed to determine the fracture location (medial, middle or lateral), type (simple or comminuted), displacement and shortening. 339 patients (226 males, 113 females) with an average age of 8.1 (range 0.1–17.8) were reviewed. Diagnoses of open fractures, skin tenting or neurovascular injury were rare, 0.6%, 4.1%, and 0%, respectively. 6 (1.8%) patients underwent surgical management. All decisions for surgery were made on the first consultation with the orthopaedic surgeon. For patients managed non-operatively, the mean number of clinic visits including initial consultation in the emergency department was 2.0 (±1.2). The mean number of radiology department appointments was 4.1 (± 1.0) where patients received a mean number of 4.2 (±2.9) radiographs. Complications in the non-operative group were minimal; 2 refractures in our series and no known cases of non-union. All patients achieved clinical and radiographic union and returned to sport after fracture healing. Our series suggests that the decision to treat operatively is made at the initial assessment. If no surgical indications were present at the initial assessment by the primary-care physician, then routine clinical or radiographic follow up is unnecessary. Development of a paediatric clavicle fracture pathway may reduce patient radiation exposure and reduce costs incurred by the healthcare system and patients' families without jeopardising patient outcomes

Purpose: The RCPSC Orthopaedic Specialty Committee for Residency Training and the Examination Committee for Orthopaedic Surgery requested that work be completed to assist with identifying competencies that should be included in a core curriculum for graduating orthopaedic surgery residents in Canada. The purpose of this study was to determine competencies to be of greatest importance by orthopaedic surgeons whose primary affiliation was non-university, for the purpose of developing a core curriculum in orthopaedic surgery for graduating residents within Canada. Method: A 281-item list of competencies was developed consisting of three sections: a previously validated curriculum for musculoskeletal health, Orthopaedic Specialty objectives of the Royal College of Physicians and Surgeons of Canada, curricula representing orthopaedic programs from accredited academic orthopaedic programs within Canada and, a comprehensive procedure list. Competencies were compared to existing curricula within Canada. A content review was completed and a modified questionnaire was developed. A stratified, randomized selection of, non – university, orthopaedic surgeons rated each individual item on an integer scale 1 to 4 of increasing level of importance. Summary statistics across all respondents were given. Average mean scores and standard deviations were computed. Secondary analyses were computed in general, paediatrics, trauma and adult reconstruction. Results: 131/156 (84 %) of orthopaedic surgeons participated. 240/281 competencies (85.4%) were rated average scores of at least 3.0 suggesting probably important or important to demonstrate competency by completion of training. 41/281 items (15.6%) were given average scores between 2.0 and 2.93 thus suggesting not important. Conclusion: This study identified competencies necessary for a Core Curriculum for Orthopaedic Surgery. Complex procedures in various categories and content considered less essential for orthopaedic surgeons were rated to be less important. How curriculum is ultimately structured, delivered and implemented needs to be studied. We know that learning activities are “driven” by the evaluation of competencies. Is competency-based education on the horizon or should we be focused on assessing competencies within the current method of curriculum delivery?

The aim of this surgery was to determine current practice amongst orthopaedic surgeons in New Zealand with regard to Anterior Cruciate Ligament Reconstruction. All current members of the NZOA were sent a questionnaire on the numbers and proportions of grafts performed, methods of fixation, operative technique and return to sport. One hundred and ten of 140 questionnaires were returned completed. Ninety two orthopaedic surgeons were performing ACL reconstructions. Eight per cent performed patellar tendon grafts in preference to hamstring grafts, whereas 16% preferred hamstring over patellar tendon grafts. Almost 2000 patellar tendon grafts at an average of just over 20 per surgeon are performed each year compared to just over 500 hamstring grafts at an average of just over 15 per surgeon. Metal interference screws were the most common fixation device in patellar tendon and hamstring grafts. Patellar tendon grafts are the most common grafts used for ACL reconstruction with 80 % of those surveyed preferring to use patellar tendon over hamstring grafts. Metal interference screws were the most common fixation device. There is reasonable consensus regarding return to activity and sport

Aims

The number of females within the speciality of trauma and orthopaedics (T&O) is increasing. The aim of this study was to identify: 1) current attitudes and behaviours of UK female T&O surgeons towards pregnancy; 2) any barriers faced towards pregnancy with a career in T&O surgery; and 3) areas for improvement.

Aims

Second, we explored parental recommendations to further optimize the information provision in DDH care.

Controversy exists surrounding best practice for antibiotic prophylaxis in TJR. Practicing orthopedic surgeons performing TJR in Canada were surveyed to inform regarding the most common antibiotic prophylaxis practice. Cross-sectional survey of five hundred and ninety practicing Canadian orthopaedic surgeons was conducted. Three orthopaedic surgeons, and one infectious disease specialist established face and content validity of the survey. The survey was mailed to surgeons, and re-mailed to non-responders at twelve-weeks. Survey included questions pertaining to prophylaxis indications, antibiotic choice, dosing, route and timing of administration in the primary and revision setting, as well as postoperative wound drainage investigation and management. Response rate after two mail-outs was 410/590 (69.5%). 96.6% indicated routine use of systemic prophylactic antibiotics for uncomplicated primary TJR. Cefazolin was most commonly prescribed (97.3 %), with 1gm Cefazolin the most common dosage (70.2%). Vancomycin was prescribed 26% of the time as first line. 48.5% administer the antibiotic in the operating suite, and 90% administer within < sixty minutes prior to skin incision. 47.8% routinely use antibiotics in acrylic cement, and 50% use it in a commercially prepared form. Postoperative prophylaxis duration varied widely with 42% preferring twenty-four hours. 33% routinely culture serous wound drainage within one-week postoperative in the absence of redness or fever. 19.8% prescribe antibiotics if wound drainage persists beyond hospital stay. 15.6% would conduct intraoperative wound exploration if drainage persists beyond postoperative day four. 63.9% stated they routinely withhold antibiotics until they have obtained a deep tissue culture specimen in revision TJR. 74% use the same antibiotic prophylaxis regimen for both primary and revision procedures. Of responding surgeons, 47/410 (11.8%) were categorised as high volume performing > two hundred TJR’s per year, and 40/410 (9.8%) were categorised as low volume performing < twenty-five per year. Comparative results to be discussed. Opinions vary widely amongst surgeons in Canada, illustrating the controversy in what constitutes ‘best practice’. Despite available published data, a large proportion of Canadian surgeons may fall short in meeting optimal standards of care in some domains such as the dose prescribed and timing of administration. This survey also illustrates the lack of available information to guide current management of postoperative wound drainage in the face of shorter patient hospital stays. Much work is needed in this area to determine risks and benefits of these costly tests and interventions in treating arthroplasty patients

Aims

To describe the epidemiology of acetabular fractures including patient characteristics, injury mechanisms, fracture patterns, treatment, and mortality.

Aims. High-quality clinical research in children’s orthopaedic surgery has lagged behind other surgical subspecialties. This study used a consensus-based approach to identify research priorities for clinical trials in children’s orthopaedics. Methods. A modified Delphi technique was used, which involved an initial scoping survey, a two-round Delphi process and an expert panel formed of members of the British Society of Children’s Orthopaedic Surgery. The survey was conducted amongst orthopaedic surgeons treating children in the United Kingdom and Ireland. Results. A total of 86 clinicians contributed to both rounds of the Delphi process, scoring priorities from one (low priority) to five (high priority). Elective topics were ranked higher than those relating to trauma, with the top ten elective research questions scoring higher than the top question for trauma. Ten elective, and five trauma research priorities were identified, with the three highest ranked questions relating to the treatment of slipped capital femoral epiphysis (mean score 4.6/ 5), Perthes’ disease (4.5) and bone infection (4.5). Conclusion. This consensus-based research agenda will guide surgeons, academics and funders to improve the evidence in children’s orthopaedic surgery and encourage the development of multicentre clinical trials.

Tissue engineering is a rapidly expanding field of research. Bone and cartilage engineering are being undertaken in an attempt to treat osteoarthritis and repair bone defects. In spite of extensive research little successful clinical application of this work has been seen. There are however many advances in the field that one day may have therapeutic interest. One particular area of interest is the potential for using osteophyte tissue in repairing osteoarthritic defects. Osteophytes represent an attempt by the body to regenerate bone and cartilage. They present an obvious source of cells for tissue engineering. Research ay QUT has shown that cells within the osteophytes are a better source of bone and cartilage regeneration in the laboratory than matched patient’s bone marrow stem cells. Osteoarthritis remains the ultimate challenge for orthopaedic tissue engineering. Understanding the chemical and mechanical signals occurring in osteoarthritis presents opportunities for targeted drug delivery and potential slowing of disease. We have identified changes within the MMP profile of cells at the osteochondral junction. Subchondral sclerosis appears to be associated with changes in the nature of chondrocytes deep within the cartilage layer. This transformation of chondrocytes into osteoblast-like tissue in many ways mimics the changes seen in the growth plate once maturity is reached. Understanding the parallels between these processes may help answer some of the mechanisms of the development of osteoarthritis. This talk will discuss the above topics as well as other areas of interest to an orthopaedic surgeon working within a group of 10 cell biologists

Aims

Although the short stem concept in hip arthroplasty procedure shows acceptable clinical performance, we sometimes get unexplainable radiological findings. The aim of this retrospective study was to evaluate changes of radiological findings up to three years postoperatively, and to assess any potential contributing factors on such radiological change in a Japanese population.
