The attitudes of orthopaedic surgeons regarding radiology reporting is not well-described in the literature. We surveyed Orthopaedic Surgeons in Australia and New Zealand to assess if they routinely review formal radiology reports. An anonymized, 14 question online survey was distributed to consultant surgeons of the Australian and New Zealand Orthopaedic Associations (AOA, NZOA). Two hundred respondents completed the survey (Total number of Fellows: 283 NZOA, 1185 AOA). 18.5% of respondents always reviewed the formal Radiology report, 44.5% most of the time, 35% sometimes and 2% never. By imaging modality, MRI reports were the most frequently reviewed (92%), followed by ultrasound (74%) and nuclear medicine (63%). Only 10% of surgeons consulted formal reports for plain radiography. 55% of surgeons were still likely to disagree with the MRI report, followed by 46% for plain radiography. In cases of disagreement, only 21% of surgeons would always contact the reporting radiologist. The majority of Surgeons (85.5%) think there should be more collaboration between the disciplines, although only 50.5% had regular attendance of a Radiologist at their departmental audit. This survey reveals that the majority of orthopaedic surgeons are not routinely reading radiology reports. This points towards a need for further interdisciplinary collaboration. To our knowledge, this is the first survey directly assessing attitudes of orthopaedic surgeons towards radiology reports

The 2020-2021 Canadian Residency Matching Service (CaRMS) match year was altered on an unprecedented scale. Visiting electives were cancelled at a national level, and the CaRMS interview tour was moved to a virtual model. These changes posed a significant challenge to both prospective students and program directors (PDs), requiring each party to employ alternative strategies to distinguish themselves throughout the match process. For a variety of reasons, including a decline in applicant interest secondary to reduced job prospects, the field of orthopaedic surgery was identified as vulnerable to many of these changes, creating a window of opportunity to evaluate their impacts on students and recruiting residency programs. This longitudinal survey study was disseminated to match-year medical students (3rd and 4th year) with an interest in orthopaedic surgery, as well as orthopaedic surgery program directors. Responses to the survey were collected using an electronic form designed in Qualtrics (Qualtrics, 2021, Provo, Utah, USA). Students were contacted through social media posts, as well as by snowball sampling methods through appropriate medical student leadership intermediates. The survey was disseminated to all 17 orthopedic surgery program directors in Canada. A pre-match and post-match iteration of this survey were designed to identify whether expectations differed from reality regarding the effect of the COVID-19 pandemic on the CaRMS match 2020-2021 process. A similar package was disseminated to Canadian orthopaedic surgery program directors pre-match, with an option to opt-in for a post-match survey follow-up. This survey had a focus on program directors’ opinions of various novel communication, recruitment, and assessment strategies, in the wake of the COVID-19 pandemic. Students’ responses to the loss of visiting electives were negative. Despite a reduction in financial stress associated with reduced need to travel (p=0.001), this was identified as a core component of the clerkship experience. In the case of virtual interviews, students’ initial trepidation pre-CaRMS turned into a positive outlook post-CaRMS (significant improvement, p=0.009) indicating an overall satisfaction with the virtual interview format, despite some concerns about a reduction in their capacity to network. Program directors and selection committee faculty also felt positively about the virtual interview format. Both students and program directors were overwhelmingly positive about virtual events put on by both school programs and student-led initiatives to complement the CaRMS tour. CaRMS was initially developed to facilitate the matching process for both students and programs alike. We hope to continue this tradition of student-led and student-informed change by providing three evidence-based recommendations. First, visiting electives should not be discontinued in future iterations of CaRMS if at all possible. Second, virtual interviews should be considered as an alternative approach to the CaRMS interview tour moving forward. And third, ongoing virtual events should be associated with a centralized platform from which programs can easily communicate virtual sessions to their target audience

LCPD can cause femoral head deformity and osteoarthritis requiring total hip replacement (THR). Currently, there is little data on how patients are functioning after a THR from patients’ perspective. The purpose of this study was to collect a large patient-reported outcome data set on adults with LCPD, including those who had a THR, using a Web-survey method and to compare their outcomes to a normative population. An English REDCap-based survey was built and made available on a LCPD study group website. The survey included childhood and adult LCPD history, SF-36 Health Survey, and the Hip Disability and Osteoarthritis Outcome Score (HOOS). Statistical analysis included t-test and linear and proportional odds regressions. Of the 1182 participants who completed the survey, 261 participants (89 M, 172 F) had a THR. The mean age at survey was 44.6±12.4 years (range 20–79). The mean duration since THR was 7.2±8 years (median 4, range 0–43). Gender and age matched analysis showed that THR participants had significantly lower HOOS Quality-of-Life and Sports scores (p<0.0001) for all age groups in comparison to a normative cohort. In women, the HOOS Symptoms, Daily Living, and Pain scores were also significantly lower in the <55 age groups (p<0.05). Similarly, SF-36 scores were significantly lower (p<0.05) in female <45 age groups in 5 out of 8 SF-36 scales. Overall, hip dysplasia and the number of years-from-THR were the main factors associated with worse SF-36 and HOOS scores. In comparison to the non-THR participants, THR participants had higher scores in some of the HOOS and SF-36 scales. LCPD participants with THR had significantly worse HOOS and SF-36 scores in most of the scales studied than a normative cohort, especially in women. There is significant disability even after a THR, warranting continued efforts to improve treatment and outcome

Physician health is a global concern, with increasing research efforts directed towards the challenge. Australia has limited published specialty-specific well-being data for trainees and consultants in medicine and surgery. We measured distress in Australian Orthopaedic trainees using the Physician Well-Being Index (PWBI, MedEd Web Solutions) using an online anonymous survey sent by the Australian Orthopaedic Association. The survey response rate was 38% (88/230). Forty-four percent of survey respondents met criteria for distress. Self-reported burnout in the 30 days prior was reported by 63% of respondents. Fifty-eight percent of females and 41% of males met criteria for distress. Of the 19% or respondents identifying as an ethnic minority, 53% were distressed compared to 42% of those identifying as non-ethnic minority. Trainees without a mentor had a 50% distress rate compared to those with a mentor (37% distress rate). Twenty-five percent of all trainees wished they had picked a career outside of medicine and 16% wished they had pursued a medical career other than Orthopaedic Surgery. Of those trainees who had already passed the fellowship exam, 17% wished they had pursued a career outside of medicine and 21% wished they had pursued a medical career in an area other than Orthopaedic Surgery. These findings suggest concerning rates of career regret and gender-related trends in distress in Australian Orthopaedic trainees. Females may be over-represented in our results as 17% of the source population was female compared to 22% of respondents. Further research is required across all Australian specialties to gain further understanding of factors contributing to distress and to assist in the development of strategy to protect against physician burnout

Aims. Orthopaedic surgery requires grafts with sufficient mechanical strength. For this purpose, decellularized tissue is an available option that lacks the complications of autologous tissue. However, it is not widely used in orthopaedic surgeries. This study investigated clinical trials of the use of decellularized tissue grafts in orthopaedic surgery. Methods. Using the ClinicalTrials.gov (CTG) and the International Clinical Trials Registry Platform (ICTRP) databases, we comprehensively surveyed clinical trials of decellularized tissue use in orthopaedic surgeries registered before 1 September 2022. We evaluated the clinical results, tissue processing methods, and commercial availability of the identified products using academic literature databases and manufacturers’ websites. Results. We initially identified 4,402 clinical trials, 27 of which were eligible for inclusion and analysis, including nine shoulder surgery trials, eight knee surgery trials, two ankle surgery trials, two hand surgery trials, and six peripheral nerve graft trials. Nine of the trials were completed. We identified only one product that will be commercially available for use in knee surgery with significant mechanical load resistance. Peracetic acid and gamma irradiation were frequently used for sterilization. Conclusion. Despite the demand for decellularized tissue, few decellularized tissue products are currently commercially available, particularly for the knee joint. To be viable in orthopaedic surgery, decellularized tissue must exhibit biocompatibility and mechanical strength, and these requirements are challenging for the clinical application of decellularized tissue. However, the variety of available decellularized products has recently increased. Therefore, decellularized grafts may become a promising option in orthopaedic surgery.

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

Hip precautions are currently practiced in three-quarters of trauma hospitals in the UK, despite national recommendations from the ‘Blue Book’ not stating it as a requirement. Valuable therapist time is utilised alongside the need for specialised equipment, which can potentially delay discharge whilst it is being arranged. Objective of this study was to explore the current practice of the use of hip precautions on discharge following hemiarthroplasty for hip fractures. To also explore whether they are necessary and to identify areas for improvement to benefit patient care overall. Online survey distributed to various Trauma and Orthopaedic Departments across the UK. Survey was available over a 4-month period, collecting 55 responses overall. Majority of responses were from trauma and orthopaedic consultants who were aware of the ‘Blue Book’ recommendations. The majority of trusts who responded did not practice hip precautions and did not feel this increased the risk of dislocations on discharge. Recommendations included integration of hip precautions in the post-op advice in coordination with the physiotherapist and information leaflets on discharge regarding hip precautions. Hip precautions were not commonly practiced, for reasons including patient compliance and the inherently stable procedure of a hemiarthroplasty compared to a THR, reducing the need for hip precautions. Hip precautions are not widely regarded as a useful practice for post-hip hemiarthroplasty, viewed as utilising more resources and increasing costs and risk due to increased hospital stay. Thus, this potentially delays discharge overall. A consistent approach should be implemented in treating patients post-hip hemiarthroplasty

Aim. Suppressive antimicrobial therapy (SAT) is used worldwide for patients with a prosthetic joint infection (PJI but clear definitions or guidelines regarding the indications, antimicrobial strategy or treatment duration are currently lacking in the literature. The aim of this study was to identify the global differences in the clinical practice of SAT for PJI. Method. An online survey was designed to investigate the current opinion on indication and treatment goals, preferred antimicrobial drugs, dosing and treatment duration and follow-up of patients with PJI on suppression. The survey was distributed using e-mail lists of several international bone and joint infection societies and study groups. Recipients were asked to share the survey with colleagues who were not a member of one of the societies but who were involved in PJI care. Results. The questionnaire was fully completed by 330 physicians from 43 different countries on six continents (Europe, n=134, 41%; Oceania n=112, 34%; North America, n=51, 16%; other, n=33, 10%; total response rate 14%). Antimicrobial treatment for PJI was discussed in a multidisciplinary team in Europe (90%), Oceania (42%) and North America (12%). In six of eight (75%) different clinical scenarios, respondents from North America would most often place a patient on SAT. In seven of eight (88%) scenarios, SAT was started least often by European respondents. The presence of a fistula was considered a contra-indication for suppression by 74 respondents (22%). First choices of SAT for staphylococcal PJI were: oral cephalosporins (39%) and tetracyclines (31%) in North America; anti-staphylococcal penicillins (55%) and oral cephalosporins (24%) in Oceania; tetracyclines (27%) and anti-staphylococcal penicillins (22%) in Europe. For streptococcal PJI, most clinicians preferred penicillins (91% in Oceania, 67% in Europe, and 53% in North America). Preferred SAT for gram negative PJI was: fluoroquinolones and a penicillin/betalactamase inhibitor in North America (26% and 18%, respectively) and Oceania (23% and 27%, respectively); fluoroquinolones (31%) and Cotrimoxazole (28%) in Europe. The dosage of SAT was never lowered (n=126, 38%), standardly lowered for all antibiotics (n=79, 24%) or only lowered for specific antibiotics (n=125, 38%). SAT was prescribed for an indefinite duration (n=43, 13%), as fixed duration between six months and three years (n=104, 32%) or for an undetermined prespecified duration (n=154, 47%). Conclusions. Substantial variation in the practice of SAT for PJI exists between physicians worldwide and throughout the different continents. This reflects the paucity of data regarding the indication and treatment of PJI with SAT

Background. Low back pain (LBP) is a major problem across the globe and is the leading cause worldwide of years lost to disability. Self-management is considered an important component the treatment of people with non-specific LBP. However, it seems that the self-management support for people with non-specific LBP provided by physiotherapists can be improved. Moreover, the way exercise therapists (ET) address self-management in practice is unknown. Purpose. To investigate the ideas, opinions and methods used by physiotherapists and ET with regard to self-management and providing self-management support to patients with non-specific LBP. Methods. This study was a qualitative survey. An online questionnaire with open-ended questions was developed. The survey was conducted among physiotherapists and ET working in the Netherlands. Data was analysed using thematic analysis. Results. Respondents considered self-management support an important topic in physiotherapy and exercise therapy for people with non-specific LBP. In the self-management support provided by the respondents, providing information and advice were frequently mentioned. The topics included in the support given by the respondents covered a broad range of important factors. The topics frequently focused on biomechanical factors. Therapists mainly provided patient education rather than self-management support. Moreover, important self-management skills were generally not addressed sufficiently. The majority of respondents had a need with regard to self-management or providing self-management support. These needs include having more knowledge, skills and tools aimed at facilitating self-management. Conclusion. The way physiotherapists and ET address self-management in people with non-specific LBP is not optimal and should be improved. Conflicts of interest: No conflicts of interest. Sources of funding: No funding obtained. Previous publication: This work was published in a scientific journal: Hutting N, Oswald W, Staal JB, Heerkens YF. Self-management support for people with non-specific low back pain: A qualitative survey among physiotherapists and exercise therapists.

Aims. The primary aim of the survey was to map the current provision of simulation training within UK and Republic of Ireland (RoI) trauma and orthopaedic (T&O) specialist training programmes to inform future design of a simulation based-curriculum. The secondary aims were to characterize; the types of simulation offered to trainees by stage of training, the sources of funding for simulation, the barriers to providing simulation in training, and to measure current research activity assessing the educational impact of simulation. Methods. The development of the survey was a collaborative effort between the authors and the British Orthopaedic Association Simulation Group. The survey items were embedded in the Performance and Opportunity Dashboard, which annually audits quality in training across several domains on behalf of the Speciality Advisory Committee (SAC). The survey was sent via email to the 30 training programme directors in March 2019. Data were retrieved and analyzed at the Warwick Clinical Trials Unit, UK. Results. Overall, 28 of 30 programme directors completed the survey (93%). 82% of programmes had access to high-fidelity simulation facilities such as cadaveric laboratories. More than half (54%) had access to a non-technical skills simulation training. Less than half (43%) received centralized funding for simulation, a third relied on local funding such as the departmental budget, and there was a heavy reliance on industry sponsorship to partly or wholly fund simulation training (64%). Provision was higher in the mid-stages (ST3-5) compared to late-stages (ST6-8) of training, and was formally timetabled in 68% of prostgrammes. There was no assessment of the impact of simulation training using objective behavioural measures or real-world clinical outcomes. Conclusion. There is currently widespread, but variable, provision of simulation in T&O training in the UK and RoI, which is likely to expand further with the new curriculum. It is important that research activity into the impact of simulation training continues, to develop an evidence base to support investment in facilities and provision

A retrospective follow-up study was done, assessing regional practices in acute cervical reduction in hospitals in the Western Cape. The constitutional court ruled on the urgency in managing cervical dislocations, and our task is to ensure that medical treatment is optimized to comply with best medical practice and the apex court. A questionnaire was distributed and completed by emergency departments at each hospital, the results retrieved, analysed, and compared to a similar survey done in 2016. Protocols for managing cervical spine dislocations had improved from 80% having no protocols to only over half of facilities (52,6%) not having protocols in place. Inadequate equipment availability remained a problem with only 50% of facilities having adequate equipment available in 2016 to 43,6% in 2023. 10,3% of participants did not know if there was equipment available. In terms of knowledge, there remained poor formal training with a drop from 93% participants identifying that the main indication to attempt emergency cervical reduction was acute cervical dislocation with worsening neurology, to only 46,2%. However, there was an increase in the number of participants who thought reduction was safe. The same percentage of participants from 2016 to 2023 would attempt emergency cervical reduction if given adequate training. Previously we found that most Western Cape hospitals had inadequate protocols, training, and equipment for cervical reductions. In 2023, more hospitals in the Province have protocols in place for cervical reductions and the same percentage of doctors would attempt emergency cervical reduction with adequate training. However, equipment and training for management of acute cervical dislocations has not improved. We conclude that most Western Cape Hospitals are unprepared to adequately manage acute cervical dislocations

Introduction. Recent advances in minimally invasive surgery and improved post-operative pain management make it possible to perform major foot/ankle operations as day-case. This could have significant impact on length of stay, saving resources and is in keeping with government policy. However, there are theoretical concerns about complications and low patient satisfaction due to pain. Methods. The survey was developed following review of the literature and was approved for distribution by the BOFAS (British Orthopaedic Foot & Ankle Society) scientific committee. An online survey (19 questions) was sent to UK foot and ankle surgeons via the BOFAS membership list. Major foot/ ankle procedures were defined as surgery that is usually performed as an inpatient in majority of centres and day-case as same day discharge, with day surgery as the intended pathway. Results. A total of 132 surgeons responded, 80% from Acute NHS Trusts. The majority (78%) thought that more procedures could be performed as day-case at their centre. Currently 45% of respondents perform less than 100 day-case surgeries per year for these procedures. Despite post-operative pain and patient satisfaction being theoretical concerns for day-case surgery in this population; these outcomes were only measured by 34% and 10% of respondents respectively. The top perceived barriers to performing more major foot and ankle procedures as day-case were: Lack of physiotherapy input pre/post-operatively (23%), Lack of out of hours support (21%). Conclusions. There is consensus among surgeons to do more major foot/ ankle procedures as day-case. Despite theoretical concerns about post-operative pain and satisfaction this was only measured by a third of those surveyed. Out of hours support and physiotherapy input pre/ post-op were perceived as the main barriers. There is a need to scope the provision of physiotherapy pre/post-operatively and out of hours support at sites where this is a perceived barrier

Aim. Pelvic osteomyelitis following pressure ulceration results in substantial patient morbidity. Previous studies have reported a heterogenous approach to diagnosis and medical management by physicians, suggesting equipoise on key clinical questions. This study hypothesised that the same equipoise exists amongst Orthopaedic surgeons. Method. An 18-question multiple-choice questionnaire was designed through an iterative feedback process until the final version was agreed by all authors. Likert-type scale responses were used with graded responses (e.g., never/fewer than half of patients/around half of patients/more than half of patients/every patient). The online survey was sent to members of the Musculoskeletal Infection Society (MSIS), the European Bone and Joint Infection Society (EBJIS), and the ESCMID Study Group for Implant-Associated Infections (ESGIAI). No incentive for participation was provided. Results. Amongst respondents, 22/41 were based in Europe and 10/41 from the USA. The majority (29/41) had been in clinical practice between 5—24 years. There was a high priority placed on bone biopsy histology, culture-positive bone sampling, and palpable bone without periosteal covering for diagnosis. Multidisciplinary team approach with plastic surgery involvement at the index procedure was advocated. The strongest indications for surgical intervention were source control for sepsis, presence of an abscess/collection, and prevention of local osteomyelitis progression. Physiological/psychological optimisation and control of acute infection were the primary determinants of surgical timing. There was low utilisation of adjunctive surgical therapies. Local/regional primary tissue transfer or secondary healing with/without VAC were the preferred techniques for wound closure. Recurrent osteomyelitis was the most common reason for prolonged antimicrobial therapy. The majority received bedside advice from an infectious disease-specialist but a quarter of respondents preferred telephone advice. Conclusions. Amongst an international cohort of Orthopaedic Surgeons there was a heterogenous diagnostic and therapeutic approach to pressure-related pelvic osteomyelitis

Introduction. The direct anterior approach (DAA) total hip arthroplasty (THA) is now widely used. A recent unpublished survey of 1000 AAHKS members found that over half currently used a DAA technique and that most users felt the DAA was financially beneficial to their practice. Conversely, non-DAA users felt that their surgical volume had decreased. An online survey of Hip Society (HS) members was done to determine member's preference for a surgical approach and opinions regarding the DAA. Methods. 71 of 112 active and senior HS members (63%) responded to this 20-question survey. Results. The survey found that only 17% of respondents had trained in an anterior approach during residency, but that half (35 respondents) had used this approach in practice at one time. Subsequently, 43% of those 35 DAA users had abandoned it. The DAA learning curve was estimated at over 50 cases by 47% of respondents. Only 23% of 71 respondents answered “yes” to the statement “Do you believe that evidence-based medicine proves significant benefits over risks of the DAA THA versus other approaches?” Financial factors were common reasons for beginning to use the technique including accommodating patient requests and preventing the loss of patients to other DAA surgeons. Conclusion. 15 years after the emergence of “minimally invasive” DAA THA, a literature review finds that only one small (44 patient) clinical trial with >1-year follow-up showed small early functional benefits but with longer average surgical times and higher blood loss. If the DAA procedure has minimal benefits, is more difficult to perform with a high complication rate (LFCN injury, femoral fracture and loosening) in the hands of non-specialists and has a long learning curve (that caused a significant percentage of HS DAA users to abandon it), then financial factors must be the main reasons for its popularity.

Background. This survey was conducted to gain information about how surgeons use scientific literature and how this is influenced by their knowledge of evidence-based medicine. The results were compared to a survey conducted 10 years previously. Where appropriate, the same questions as in the 2003 survey were used. Methods. We administered a voluntary questionnaire to participants at the AO Foundation courses in Davos, Switzerland, in December 2013. We surveyed, amongst other topics, the surgeons’ levels of education in Evidence-Based Medicine (EBM), how they implement EBM in daily practice and their publication record. Results. A total of 330 surgeons completed the 27 question survey. 49% (159/322) had learned about EBM in medical school. However, 69% (110/159) of those with EBM education had taken only one semester or less on the subject. 54% of participants (170/317) correctly identified a definition of EBM in surgery. This compares to 45% in the 2003 survey (130/288 respondents) of a subset who said they have previously heard of evidence-based orthopaedic surgery. When it came to applying EBM in their daily work, 45% of respondents (143/320) claim to always practice it (2003 figure: 28%, 113/404), while 26% (84/320) only use EBM for difficult or controversial cases (2003 figure: 26%, 104/404). 27% (88/323) have never published a manuscript as an author or co-author (2003 figure: 14%, 121/453), 53% (170/323) have been involved in 1–10 publications (2003 figure: 59%, 269/453), and 20% (65/323) have published more than 10 times (2003 figure: 27%, 63/453). Conclusions. While at face value there appears to be a greater understanding and utilisation of EBM among AO course participants who completed the 2013 survey compared to the 2003 study, several outcomes do not show any great variation in the intervening decade.

Aim. Deep infection following endoprosthetic replacement (EPR) of long bones is a devastating complication occurring in 15% of musculoskeletal tumour patients. The recently published PARITY Trial demonstrated that extending antibiotic prophylaxis from 24 hours to 5 days does not reduce infection rates. However, questions remain about the optimal antibiotic choice and dose. Method. A 23-question multiple-choice questionnaire was designed and piloted through an iterative feedback process until the final version was agreed by all authors. Open and closed-ended questions were used to gather information on practice and Likert-type scale responses were used to grade responses to ascertain surgeon perceptions and preferences. The online survey was sent to all surgeon delegates of the 34th Annual Meeting of the European Musculo-Skeletal Oncology Society in London in October 2022. Results. Amongst 61 respondents, 43 were based in Europe and 18 outside of Europe. The majority (48/61) had been in clinical practice over 11 years. Antibiotic choice. 1st or 2nd generation cephalosporins were the first line choice practiced among 49 (80.3%) of respondents. Of these, 39 responded had a 2nd line protocol for beta-lactam allergy which was most commonly clindamycin (18), vancomycin (11) or a combination of a glycopeptide or clindamycin plus gentamicin (4). Respondents changed their first line regimen for radiotherapy in 6/61, chemotherapy in 8/61 and tumour site in 20/61. Re-dosing. Intraoperative re-dosing intervals of 1st and 2nd generation cephalosporins ranged from 2 to 8 hourly. Re-dosing for blood loss ranged from never to when 2 litres was lost. Of the 47 respondents, 24 said intraoperative re-dosing is always reliably administered. Duration. Six (10%) of 61 respondent routinely cover the intraoperative period only, whereas 30 (49%) give 24 hours, 16 (give 48 hours or longer and 8 continue until surgical drains are removed. 31 of 61 change duration depending on clinical situation. The most common reasons for changing were patient risk factors, soft tissue status and previous radiotherapy. 57/61 surgeons were aware of the PARITY Trial. When these respondents were asked whether they had changed practice based on PARITY, 12 said yes, 24 said no and 21 said they always give 24 hours anyway. Conclusions. Amongst an international cohort of orthopaedic oncology surgeons there was a wide variation in practice. Further research should focus on the optimum choice and re-dosing strategy, which have not been defined

Aims

To identify factors influencing clinicians’ decisions to undertake a nonoperative hip fracture management approach among older people, and to determine whether there is global heterogeneity regarding these factors between clinicians from high-income countries (HIC) and low- and middle-income countries (LMIC).

Tourniquet use in total knee arthroplasty (TKA) remains a subject of considerable debate. A recent study questioned the need for tourniquets based on associated risks. However, the study omitted analysis of crucial tourniquet-related parameters which have been demonstrated in numerous studies to be associated with safe tourniquet use and reduction of adverse events. The current utilization and preferences of tourniquet use in Canada remain unknown. Our primary aim was to determine the current practices, patterns of use, and opinions of tourniquet use in TKA among members of the Canadian Arthroplasty Society (CAS). Additionally, we sought to determine the need for updated best practice guidelines to inform optimal tourniquet use and to identify areas requiring further research. A self-administered survey was emailed to members of the CAS in October 2021(six-week period). The response rate was 57% (91/161). Skip logic branching was used to administer a maximum of 59 questions related to tourniquet use, beliefs, and practices. All respondents were staff surgeons and 88% were arthroplasty fellowship trained. Sixty-five percent have been in practice for ≥11 years and only 16% for 50 TKA/year, 59% have an academic practice, and >67% prefer cemented TKA. Sixty-six percent currently use tourniquets, 25% no longer do but previously did, and 9% never used tourniquets. For those not using tourniquets, the most common reasons are potential harm/risks and publications/conferences. Among current users, 48% use in all cases and an additional 37% use in 76-99% of cases. The top reason for use was improved visualization/bloodless field (88%), followed by performing a cemented TKA, used in training, and faster operative times. The main patient factor influencing selective tourniquet use was peripheral vascular disease and main surgical factors were operative duration and cementless TKA. The most frequent adverse events reported were bruising/pinching under the tourniquet and short-term pain, which majority believed were related to improper tourniquet use (prolonged time, high-pressures, poor cuff fit), yet only 8% use contoured tourniquets and 32% don't use limb protection. Despite substantial evidence in literature that tourniquet safety and probability of harm are affected by tourniquet time and pressure, only 83% and 72% of respondents believe reducing tourniquet time and pressure respectively reduce the probability of harm. In addition, no surgeon utilizes personalized limb occlusion pressure which has been demonstrated to substantially reduce tourniquet pressure while being safe and effective. Furthermore, 62% always use fixed pressure and 37% will modify the pressure based on patient parameters, most often systolic blood pressure and limb size. Almost all (88%) were interested in new evidence-based guidelines regarding these parameters. Tourniquet use in TKA remains prevalent among arthroplasty surgeons in the CAS; however tremendous practice variability regarding several key parameters required for optimal use exists. Current best practices of tourniquet use regarding personalized pressures, time, and type are not being utilized across Canada. There is considerable interest and need for further research and updated guidelines regarding key parameters of safe tourniquet usage to optimize tourniquet use in TKA

Objectives. Evidence -based medicine (EBM) is designed to inform clinical decision-making within all medical specialties, including orthopaedic surgery. We recently published a pilot survey of the Canadian Orthopaedic Association (COA) membership and demonstrated that the adoption of EBM principles is variable among Canadian orthopaedic surgeons. The objective of this study was to conduct a broader international survey of orthopaedic surgeons to identify characteristics of research studies perceived as being most influential in informing clinical decision-making. Materials and Methods. A 29-question electronic survey was distributed to the readership of an established orthopaedic journal with international readership. The survey aimed to analyse the influence of both extrinsic (journal quality, investigator profiles, etc.) and intrinsic characteristics (study design, sample size, etc.) of research studies in relation to their influence on practice patterns. Results. A total of 353 surgeons completed the survey. Surgeons achieved consensus on the ‘importance’ of three key designs on their practices: randomised controlled trials (94%), meta-analyses (75%) and systematic reviews (66%). The vast majority of respondents support the use of current evidence over historical clinical training; however subjective factors such as journal reputation (72%) and investigator profile (68%) continue to influence clinical decision-making strongly. Conclusion. Although intrinsic factors such as study design and sample size have some influence on clinical decision-making, surgeon respondents are equally influenced by extrinsic factors such as investigator reputation and perceived journal quality.

INTRODUCTION. 3D preoperative planning software for anatomic and reverse total shoulder arthroplasty (ATSA and RTSA) provides additional insight for surgeons regarding implant selection and placement. Interestingly, the advent of such software has brought previously unconsidered questions to light on the optimal way to plan a case. In this study, a survey of shoulder specialists from the American Shoulder and Elbow Society (ASES) was conducted to examine thought patterns in current glenoid implant selection and placement. METHODS. 172 ASES members completed an 18-question survey on their thought process for how they select and place a glenoid implant for both ATSA and RTSA procedures. Data was collected using a custom online Survey Monkey survey. Surgeon answers were split into three cohorts based on their responses to usage of 3D preoperative planning software: high users, seldom users, and non-users. Data was analyzed for each cohort to examine differences in thought patterns, implant selection, and implant placement. RESULTS. 76 surgeons were grouped into the high user cohort, 66 into the seldom user cohort, and 30 into the non-user cohort. 61.9% of high users and 74.1% of seldom users performed >75 shoulder arthroplasties per year, whereas only 19.9% of non-users performed >75 arthroplasties per year (Figure 1). When questioned on glenoid implant type selection (augmented vs. non-augmented components), 80.3% of high users reported augment usage for both ATSA and RTSA, with using augments >45% of the time in 18.4% of ATSA cases and in 22.3% of RTSA cases. For seldom users, 80.3% reported augment usage in ATSA cases, and 70.3% in RTSA cases. Seldom users reported augment usage >45% of the time in 4.5% of ATSA cases and in 1.6% of RTSA cases. For non-preoperative planning users, 53.3% reported using augments in ATSA cases, and 48.3% for RTSA cases. Non-users used augmented glenoid components >45% of the time in 6.6% of ATSA cases and in 6.8% of RTSA cases. For resultant implant superior inclination in RTSA, 40.8% of high users aim for 0° of inclination, followed by 31.8% for seldom users and 16.7% of non-users (Figure 2). CONCLUSION. The results of this study show that 3D preoperative planning software has an influence on the decision making process when planning a shoulder arthroplasty. High volume shoulder arthroplasty surgeons report higher preoperative planning software usage than low volume surgeons, suggesting the utility of such software. Augmented glenoid component usage for both ATSA and RTSA is also higher for surgeons that use preoperative planning software, which either suggests the utility of augmented glenoid components, or that the use of such software creates the perceived need for augmented glenoid components. Lastly, surgeons who preoperatively plan tend to orient their glenoid components differently, which could suggest either a better understanding of the anatomy through the use of the software, or an influence on mindset regarding implant orientation resulting from software usage. This highlights an area for future work that could correlate clinical outcome data to implant selection and placement to prove what is the optimal plan for a given patient.
