Aims. The aims of this study were to describe the demographic, socioeconomic, and educational factors associated with core surgical trainees (CSTs) who apply to and receive offers for higher surgical training (ST3) posts in Trauma & Orthopaedics (T&O). Methods. Data collected by the UK Medical Education Database (UKMED) between 1 January 2014 and 31 December 2019 were used in this retrospective longitudinal cohort study comprising 1,960 CSTs eligible for ST3. The primary outcome measures were whether CSTs applied for a T&O ST3 post and if they were subsequently offered a post. A directed acyclic graph was used for detecting confounders and adjusting logistic regression models to calculate odds ratios (ORs), which assessed the association between the primary outcomes and relevant exposures of interest, including: age, sex, ethnicity, parental socioeconomic status (SES), domiciliary status, category of medical school, Situational Judgement Test (SJT) scores at medical school, and success in postgraduate examinations. This study followed STROBE guidelines. Results. Compared to the overall cohort of CSTs, females were significantly less likely to apply to T&O (OR 0.37, 95% CI 0.30 to 0.46; n = 155/720 female vs n = 535/1,240 male; p < 0.001). CSTs who were not UK-domiciled prior to university were nearly twice as likely to apply to T&O (OR 1.99, 95% CI 1.39 to 2.85; n = 50/205 vs not UK-domiciled vs n = 585/1,580 UK-domiciled; p < 0.001). Age, ethnicity, SES, and medical school category were not associated with applying to T&O. Applicants who identified as ‘black and minority ethnic’ (BME) were significantly less likely to be offered a T&O ST3 post (OR 0.70, 95% CI 0.51 to 0.97; n = 165/265 BME vs n = 265/385 white; p = 0.034). Differences in age, sex, SES, medical school category, and SJT scores were not significantly associated with being offered a T&O ST3 post. Conclusion. There is an evident disparity in sex between T&O applicants and an ethnic disparity between those who receive offers on their first attempt. Further high-quality, prospective research in the post-COVID-19 pandemic period is needed to improve equality, diversity, and inclusion in T&O training.

Aims. Arthroplasty skills need to be acquired safely during training, yet operative experience is increasingly hard to acquire by trainees. Virtual reality (VR) training using headsets and motion-tracked controllers can simulate complex open procedures in a fully immersive operating theatre. The present study aimed to determine if trainees trained using VR perform better than those using conventional preparation for performing total hip arthroplasty (THA). Patients and Methods. A total of 24 surgical trainees (seven female, 17 male; mean age 29 years (28 to 31)) volunteered to participate in this observer-blinded 1:1 randomized controlled trial. They had no prior experience of anterior approach THA. Of these 24 trainees, 12 completed a six-week VR training programme in a simulation laboratory, while the other 12 received only conventional preparatory materials for learning THA. All trainees then performed a cadaveric THA, assessed independently by two hip surgeons. The primary outcome was technical and non-technical surgical performance measured by a THA-specific procedure-based assessment (PBA). Secondary outcomes were step completion measured by a task-specific checklist, error in acetabular component orientation, and procedure duration. Results. VR-trained surgeons performed at a higher level than controls, with a median PBA of Level 3a (procedure performed with minimal guidance or intervention) versus Level 2a (guidance required for most/all of the procedure or part performed). VR-trained surgeons completed 33% more key steps than controls (mean 22 (. sd. 3) vs 12 (. sd. 3)), were 12° more accurate in component orientation (mean error 4° (. sd. 6°) vs 16° (. sd. 17°)), and were 18% faster (mean 42 minutes (. sd. 7) vs 51 minutes (. sd. 9)). Conclusion. Procedural knowledge and psychomotor skills for THA learned in VR were transferred to cadaveric performance. Basic preparatory materials had limited value for trainees learning a new technique. VR training advanced trainees further up the learning curve, enabling highly precise component orientation and more efficient surgery. VR could augment traditional surgical training to improve how surgeons learn complex open procedures. Cite this article: Bone Joint J 2019;101-B:1585–1592

Freehand distal interlocking of intramedullary nails remains a challenging task. If not performed correctly it can be a time consuming and radiation expensive procedure. Recently, the AO Research Institute developed a new training device for Digitally Enhanced Hands-on Surgical Training (DEHST) that features practical skills training augmented with digital technologies, potentially improving surgical skills needed for distal interlocking. Aim of the study: To evaluate weather training with DEHST enhances the performance of novices without surgical experience in free-hand distal nail interlocking compared to a non-trained group of novices. 20 novices were assigned in two groups and performed distal interlocking of a tibia nail in an artificial bone model. Group 1: DEHST trained novices (virtual locking of five nail holes during one hour of training). Group 2: untrained novices without DEHST training. Time, number of x-rays, nail hole roundness, critical events and success rates were compared between the groups. Time to complete the task (sec.) and x-ray exposure (µGcm2) were significantly lower in Group1 414.7 (290–615) and 17.8 (9.8–26.4) compared to Group2 623.4 (339–1215) and 32.6 (16.1–55.3); p=0.041 and 0.003. Perfect circle roundness (%) was 95.0 (91.1–98.0) in Group 1 and 80.8 (70.1–88.9) in Group 2; p<0.001. In Group 1 90% of the participants achieved successful completion of the task (hit the nail with the drill), whereas only 60% of the participants in group 2 achieved this; p=0.121. Training with DEHST significantly enhances the performance of novices without surgical experience in distal interlocking of intramedullary nails. Besides radiation exposure and operation time the com-plication rate during the operation can be significantly reduced

Evidence supporting the use of virtual reality (VR) training in orthopaedic procedures is rapidly growing. However, the impact of the timing of delivery of this training is yet to be tested. We aimed to investigate whether spaced VR training is more effective than massed VR training. 24 medical students with no hip arthroplasty experience were randomised to learning the direct anterior approach total hip arthroplasty using the same VR simulation, training either once-weekly or once-daily for four sessions. Participants underwent a baseline physical world assessment on a saw bone pelvis. The VR program recorded procedural errors, time, assistive prompts required and hand path length across four sessions. The VR and physical world assessments were repeated at one-week, one-month, and 3 months after the last training session. Baseline characteristics between the groups were comparable (p > 0.05). The daily group demonstrated faster skills acquisition, reducing the median ± IQR number of procedural errors from 68 ± 67.05 (session one) to 7 ± 9.75 (session four), compared to the weekly group's improvement from 63 ± 27 (session one) to 13 ± 15.75 (session four), p < 0.001. The weekly group error count plateaued remaining at 14 ± 6.75 at one-week, 16.50 ± 16.25 at one-month and 26.45 ± 22 at 3-months, p < 0.05. However, the daily group showed poorer retention with error counts rising to 16 ± 12.25 at one-week, 17.50 ± 23 at one-month and 41.45 ± 26 at 3-months, p<0.01. A similar effect was noted for the number of assistive prompts required, procedural time and hand path length. In the real-world assessment, both groups significantly improved their acetabular component positioning accuracy, and these improvements were equally maintained (p<0.01). Daily VR training facilitates faster skills acquisition; however weekly practice has superior skills retention

Background. Training within surgery is changing from the traditional Halstedian apprenticeship model. There is need for objective assessment of trainees, especially their technical skills, to ensure they are safe to practice and to highlight areas for development. In addition, due to working time restrictions in both the UK and the US, theatre time is being limited for trainees, reducing their opportunities to learn such technical skills. Simulation is one adjunct to training that can be utilised to both assess trainees objectively, and provide a platform for trainees to develop their skills in a safe and controlled environment. The insertion of a dynamic hip screw (DHS) relies on complex psychomotor skills to obtain an optimal implant position. The tip-apex distance (TAD) is a measurement of this positioning, used to predict failure of the implant. These skills can be obtained away from theatre using workshop bone simulation, however this method does not utilise fluoroscopy due to the associated radiation risks. FluoroSim is a novel digital fluoroscopy simulator that can recreate digital radiographs with workshop bone simulation for the insertion of a DHS guide-wire. In this study, we present the training effect demonstrated on FluoroSim. The null hypothesis states that no difference will be present between users with different amounts of exposure to FluoroSim. Methods. Medical students were recruited from three London universities and randomised into a training (n=23) and a control (n=22) cohort. All participants watched a video explanation of the simulator and task and were blinded to their allocation. Training participants completed 10 attempts in total, 5 attempts in week one, followed by a one week wash out period, followed by 5 attempts in week 2. The control group completed a single attempt each week. For each attempt, 5 metrics were recorded; TAD, procedural time, number of radiographs, number of guide-wire retires and cut-out rate (COR). Results. No significant difference was present for any metric between the groups at baseline; randomisation had produced heterogeneous groups minimising selection bias. Intragroup training effect (comparison of initial and last attempt) was significant for all metrics in the training group (p < 0.05) but for no metrics in the control group. The intergroup training effect (comparison of training group attempt ten to control group attempt ten) was present for procedural time, number of radiographs and number of guide-wire retries (p < 0.05). Significance was not reached for TAD and COR. Conclusion. FluoroSim shows skill acquisition with repeat exposure, so the null hypothesis can be rejected. This study has demonstrated the merits of FluoroSim as a training adjunct for psychomotor skill development in a DHS setting

Aims. Global literature suggests that female surgical trainees have lower rates of independent operating (operative autonomy) than their male counterparts. The objective of this study was to identify any association between gender and lead/independent operating in speciality orthopaedic trainees within the UK national training programme. Methods. This was a retrospective case-control study using electronic surgical logbook data from 2009 to 2021 for 274 UK orthopaedic trainees. Total operative numbers and level of supervision were compared between male and female trainees, with correction for less than full-time training (LTFT), prior experience, and time out during training (OOP). The primary outcome was the percentage of cases undertaken as lead surgeon (supervised and unsupervised) by UK orthopaedic trainees by gender. Results. All participants gave permission for their data to be used. In total, 274 UK orthopaedic trainees submitted data (65% men (n = 177) and 33% women (n = 91)), with a total of 285,915 surgical procedures logged over 1,364 trainee-years. Males were lead surgeon (under supervision) on 3% more cases than females (61% (115,948/189,378) to 58% (50,285/86,375), respectively; p < 0.001), and independent operator (unsupervised) on 1% more cases. A similar trend of higher operative numbers in male trainees was seen for senior (ST6 to 8) trainees (+5% and +1%; p < 0.001), those with no time OOP (+6% and +8%; p < 0.001), and those with orthopaedic experience prior to orthopaedic specialty training (+7% and +3% for lead surgeon and independent operator, respectively; p < 0.001). The gender difference was less marked for those on LTFT training, those who took time OOP, and those with no prior orthopaedic experience. Conclusion. This study showed that males perform 3% more cases as the lead surgeon than females during UK orthopaedic training (p < 0.001). This may be due to differences in how cases are recorded, but must engender further research to ensure that all surgeons are treated equitably during their training.

Aims. Mechanical stimulation is a key factor in the development and healing of tendon-bone insertion. Treadmill training is an important rehabilitation treatment. This study aims to investigate the benefits of treadmill training initiated on postoperative day 7 for tendon-bone insertion healing. Methods. A tendon-bone insertion injury healing model was established in 92 C57BL/6 male mice. All mice were divided into control and training groups by random digital table method. The control group mice had full free activity in the cage, and the training group mice started the treadmill training on postoperative day 7. The quality of tendon-bone insertion healing was evaluated by histology, immunohistochemistry, reverse transcription quantitative polymerase chain reaction, Western blotting, micro-CT, micro-MRI, open field tests, and CatWalk gait and biomechanical assessments. Results. Our results showed a significantly higher tendon-bone insertion histomorphological score in the training group, and the messenger RNA and protein expression levels of type II collagen (COL2A1), SOX9, and type X collagen (COL10A1) were significantly elevated. Additionally, tendon-bone insertion resulted in less scar hyperplasia after treadmill training, the bone mineral density (BMD) and bone volume/tissue volume (BV/TV) were significantly improved, and the force required to induce failure became stronger in the training group. Functionally, the motor ability, limb stride length, and stride frequency of mice with tendon-bone insertion injuries were significantly improved in the training group compared with the control group. Conclusion. Treadmill training initiated on postoperative day 7 is beneficial to tendon-bone insertion healing, promoting biomechanical strength and motor function. Our findings are expected to guide clinical rehabilitation training programmes. Cite this article: Bone Joint Res 2023;12(5):339–351

Aims. To evaluate if, for orthopaedic trainees, additional cadaveric simulation training or standard training alone yields superior radiological and clinical outcomes in patients undergoing dynamic hip screw (DHS) fixation or hemiarthroplasty for hip fracture. Methods. This was a preliminary, pragmatic, multicentre, parallel group randomized controlled trial in nine secondary and tertiary NHS hospitals in England. Researchers were blinded to group allocation. Overall, 40 trainees in the West Midlands were eligible: 33 agreed to take part and were randomized, five withdrew after randomization, 13 were allocated cadaveric training, and 15 were allocated standard training. The intervention was an additional two-day cadaveric simulation course. The control group received standard on-the-job training. Primary outcome was implant position on the postoperative radiograph: tip-apex distance (mm) (DHS) and leg length discrepancy (mm) (hemiarthroplasty). Secondary clinical outcomes were procedure time, length of hospital stay, acute postoperative complication rate, and 12-month mortality. Procedure-specific secondary outcomes were intraoperative radiation dose (for DHS) and postoperative blood transfusion requirement (hemiarthroplasty). Results. Eight female (29%) and 20 male trainees (71%), mean age 29.4 years, performed 317 DHS operations and 243 hemiarthroplasties during ten months of follow-up. Primary analysis was a random effect model with surgeon-level fixed effects of patient condition, patient age, and surgeon experience, with a random intercept for surgeon. Under the intention-to-treat principle, for hemiarthroplasty there was better implant position in favour of cadaveric training, measured by leg length discrepancy ≤ 10 mm (odds ratio (OR) 4.08 (95% confidence interval (CI) 1.17 to 14.22); p = 0.027). There were significantly fewer postoperative blood transfusions required in patients undergoing hemiarthroplasty by cadaveric-trained compared to standard-trained surgeons (OR 6.00 (95% CI 1.83 to 19.69); p = 0.003). For DHS, there was no significant between-group difference in implant position as measured by tip-apex distance ≤ 25 mm (OR 6.47 (95% CI 0.97 to 43.05); p = 0.053). No between-group differences were observed for any secondary clinical outcomes. Conclusion. Trainees randomized to additional cadaveric training performed hip fracture fixation with better implant positioning and fewer postoperative blood transfusions in hemiarthroplasty. This effect, which was previously unknown, may be a consequence of the intervention. Further study is required. Cite this article: Bone Jt Open 2023;4(8):602–611

Musculoskeletal (MSK) disorders continue to be a major cause of pain and disability worldwide. The mission statement of the Canadian Orthopaedic Association (COA) is to “promote excellence in orthopaedic and musculoskeletal health for Canadians,” and orthopaedic surgeons serve as leaders in addressing and improving musculoskeletal health. However, patients with MSK complaints most commonly present first to a primary care physician. According to a survey of family physicians in British Columbia, 13.7-27.8% of patients present with a chief complaint that is MSK-related (Pinney et Regan, 2001). Therefore, providing excellent MSK care to Canadians requires that all physicians, especially those involved in primary care, be adequately trained to diagnose and treat common MSK conditions. To date, there has been no assessment of the total mandatory MSK training Canadian family medicine residents receive. It is also unclear, despite the prevalence of MSK complaints among Canadian patients, if current family physicians are competent or confident in their ability to provide fundamental MSK care. The purpose of this study is to determine the amount of mandatory MSK training Canadian family medicine residents are currently receiving. Web-based research was used to determine how many weeks of mandatory MSK training was incorporated into current Canadian family medicine residency training programs. This information was gathered from either the Canadian Resident Matching Service website (carms.ca) or the residency program's individual website. If this information was not available on a program's website, a program administrator was contacted via email in order to ascertain this information directly. MSK training was considered to be any rotation in orthopaedic surgery, spine surgery, sports medicine, or physiatry. 156 Canadian family medicine residency training sites were identified. Information pertaining to mandatory MSK education was collected for 150 sites (95.5%). Of the 150 training sites, 102(68 %) did not incorporate any mandatory MSK training into their curriculum. Of the 48 programs that did, the average number of weeks of MSK training was 3.37 weeks. 32/48 programs (66.7%) included 4 weeks of MSK training, which represents 3.8% of a 2-year training program. Current Canadian family medicine residents are not receiving sufficient musculoskeletal training when compared to the overall frequency of musculoskeletal presentations in the primary care setting. Understanding current family medicine physicians’ surveyed confidence and measured competence with respect to diagnosing and treating common musculoskeletal disorders could also prove helpful in demonstrating the need for increased musculoskeletal education. Future orthopaedic initiatives could help enhance family medicine MSK training

The imminent introduction of the new Trauma & Orthopaedic (T&O) curriculum, and the implementation of the Improving Surgical Training initiative, reflect yet another paradigm shift in the recent history of trauma and orthopaedic training. The move to outcome-based training without time constraints is a radical departure from the traditional time-based structure and represents an exciting new training frontier. This paper summarizes the history of T&O training reform, explains the rationale for change, and reflects on lessons learnt from the past. Cite this article: Bone Jt Open 2021;2-3:181–190

Previous Anterior Cruciate Ligament (ACL) reconstruction is currently a bar from entry to the Royal Marines and Royal Navy, whilst the British Army allows recruits to join if asymptomatic 18 months post ACL reconstruction. However current Royal Marines policy is to rehabilitate recruits who sustain an ACL disruption in training. We retrospectively analysed the rehabilitation times and pass out rate of Royal Marines who had an ACL disruption during recruit training over an 8 year period. 12 recruits sustained an ACL disruption during recruit training in the study period, giving an incidence of around 1.5/1000 recruits. 9 Patients underwent ACL repairs in training, with 1 patient leaving and rejoining post repair and later successfully passed out. 2 patients were treated conservatively. Of the 12 ACL sustained in training 8/12 (67%) passed out. None of the patients treated conservatively passed out. The mean time out of training for successful recruits was 51.6 weeks (95% CI 13.1) mean rehabilitation time post ACL reconstruction for successful recruits was 36.7 weeks (95% CI 12.5). Mean time to discharge for unsuccessful recruits 63.2 weeks (95% CI 42.4). In the operative group 1/10 left due to failure to return to training and 1/10 left through unrelated reasons. Current costing for recruit training is £1800 per week per recruit. ACL injuries are not common in Royal Marine Training, and reconstruction is not a bar to completing Royal Marine basic training. We estimate that it costs around £100,000 per-injured recruit, to maintain a policy of rehabilitating ACL injured recruits in Royal Marines training. Further research into the long-term employability or Royal Marines sustaining an ACL injury in training is required

Aims. The decrease in the number of satellite cells (SCs), contributing to myofibre formation and reconstitution, and their proliferative capacity, leads to muscle loss, a condition known as sarcopenia. Resistance training can prevent muscle loss; however, the underlying mechanisms of resistance training effects on SCs are not well understood. We therefore conducted a comprehensive transcriptome analysis of SCs in a mouse model. Methods. We compared the differentially expressed genes of SCs in young mice (eight weeks old), middle-aged (48-week-old) mice with resistance training intervention (MID+ T), and mice without exercise (MID) using next-generation sequencing and bioinformatics. Results. After the bioinformatic analysis, the PI3K-Akt signalling pathway and the regulation of actin cytoskeleton in particular were highlighted among the top ten pathways with the most differentially expressed genes involved in the young/MID and MID+ T/MID groups. The expression of Gng5, Atf2, and Rtor in the PI3K-Akt signalling pathway was higher in the young and MID+ T groups compared with the MID group. Similarly, Limk1, Arhgef12, and Araf in the regulation of the actin cytoskeleton pathway had a similar bias. Moreover, the protein expression profiles of Atf2, Rptor, and Ccnd3 in each group were paralleled with the results of NGS. Conclusion. Our results revealed that age-induced muscle loss might result from age-influenced genes that contribute to muscle development in SCs. After resistance training, age-impaired genes were reactivated, and age-induced genes were depressed. The change fold in these genes in the young/MID mice resembled those in the MID + T/MID group, suggesting that resistance training can rejuvenate the self-renewing ability of SCs by recovering age-influenced genes to prevent sarcopenia.

Background. Musculoskeletal disorders, including low back pain, affects 68% of UK physiotherapists across their career with patient handling considered a key risk factor. Manual handling training is mandatory for all allied health professionals, however there is limited research investigating whether professionals adopt recommended manual handling principles following training. Purpose of Study. To investigate spinal angles when facilitating sit-to-stand, and a turning manoeuvre in bed, comparing first-year physiotherapy students (who have not received manual handling training) with final-year physiotherapy students (who have received manual handling training). Methods. Cross-sectional pilot study (n= 20; 10 first-year, 10 final-year). All participants were exposed to a short training video outlining how to safely perform each manoeuvre. Retroreflective markers were attached to: L4, ASIS, PSIS, T12, C7, tragus and canthus. Spinal (neck, thoracic, lumbar and pelvic) angles were established via digital photographs using a bespoke MATLAB programme (MathWorks). A Mann-Whitney U test was conducted to determine between group differences. Results. No statistically significant results were observed between first-year and final-year students for both manoeuvres (p<0.05), except for neck angle during the turning manoeuvre (final-year students demonstrating more upright postures, p=0.037). Interestingly, for the turning manoeuvre in bed it was noted that none of the participants adjusted the bed height. Conclusion. The results suggest that clinical experience and routine manual handling training may not have a significant effect on spinal posture, especially in relation to pelvic, lumbar and thoracic angles. Further work is needed to understand how training relates to adoption of manual handling principles in practice. Conflicts of interest. None. Sources of funding. None

Orthopaedic surgery is a practical surgical specialization field, the exit exam for registrars remains written and oral. Despite logbook evaluation and surgical work-based assessments, the question remains: can registrars perform elective surgery upon qualification? In South Africa, obstacles to elective surgical training include the trauma workload, financial constraints, fellowships and the Covid pandemic. In hip and knee arthroplasty, new approaches like the direct anterior approach (DAA) and robotic-assisted knee surgery also contributed to the dilution of cases available for registrar training. There are concerns that orthopaedic registrars do not perform enough cases to achieve surgical proficiency. Review of the last 4 years of registrar logbooks in hip and knee arthroplasty surgery performed in a single tertiary academic hospital in South Africa. We included all primary total hip replacements (THR), total knee replacements (TKR) and hemiarthroplasties (HA) done for neck of femur (NOF) fractures between 1 April 2019 and 30 March 2023. Differentiation between registrar assisting, registrar performing with consultant supervision and registrar performing independent surgery was done. 990 hip arthroplasties (472 Primary THR, 216 NOF THR, 302 NOF HA) and 316 Primary TKR were performed during the study period. In primary elective THR the posterior approach was dominant and used in 76% of cases. In NOF THA the DAA was dominant used in 98% of cases. Primary TKR robotic-assisted technologies was used in 27% (n=94) cases. Registrars as the primary surgeon were the highest in NOF THA at 70% of cases and the lowest performing TKR at 25%. During 3-month rotations, an average registrar performed 12 (2 TKR and 10 THR) and assisted in 35 (10 TKR and 25 THR) cases. Despite the large number of arthroplasties operations being performed over the last 4-year period, the surgical cases done by registrars are below, the proposed minimal cases to provide surgical proficiency during their training period

Freehand distal interlocking of intramedullary nails is technical demanding and prone to handling issues. It requires the surgeon to precisely place a screw through the nail under x-ray. If not performed accurately it can be a time consuming and radiation expensive procedure. The aims of this study were to assess construct and face validity of a new training device for distal interlocking of intramedullary nails. 53 participants (29 novices and 24 experts) were included. Construct validity was evaluated by comparing simulator metrics (number of x-rays, nail hole roundness, drill tip position and accuracy of the drilled hole) between experts and novices. Face validity was evaluated by means of a questionnaire concerning training potential and quality of simulated reality using a 7-point Likert scale (range 1-7). Mean realism of the training device was rated 6.3 (range 4-7) and mean training potential as well as need for distal interlocking training was rated 6.5 (range 5-7) with no significant differences between experts and novices, p≥0.236. All participants stated that the simulator is useful for procedural training of distal nail interlocking, 96% would like to have it at their institution and 98% would recommend it to their colleagues. Total number of x-rays were significantly higher for novices (20.9±6.4 vs. 15.5±5.3), p=0.003. Successful task completion (hit the virtual nail hole with the drill) was significantly higher in experts (p=0.04; novices hit: n=12; 44,4%; experts hit: n=19; 83%). The evaluated training device for distal interlocking of intramedullary nails yielded high scores in terms of training capability and realism. Furthermore, construct validity was established as it reliably discriminates between experts and novices. Participants see a high further training potential as the system may be easily adapted to other surgical task requiring screw or pin position with the help of x-rays

Aims. Evidence exists of a consistent decline in the value and time that medical schools place upon their undergraduate orthopaedic placements. This limited exposure to trauma and orthopaedics (T&O) during medical school will be the only experience in the speciality for the majority of doctors. This review aims to provide an overview of undergraduate orthopaedic training in the UK. Methods. This review summarizes the relevant literature from the last 20 years in the UK. Articles were selected from database searches using MEDLINE, EMBASE, ERIC, Cochrane, and Web of Science. A total of 16 papers met the inclusion criteria. Results. The length of exposure to T&O is declining; the mean total placement duration of two to three weeks is significantly less than the four- to six-week minimum advised by most relevant sources. The main teaching methods described in the literature included didactic lectures, bedside teaching, and small group case-based discussions. Students preferred interactive, blended learning teaching styles over didactic methods. This improvement in satisfaction was reflected in improvements in student assessment scores. However, studies failed to assess competencies in clinical skills and examinations, which is consistent with the opinions of UK foundation year doctors, approximately 40% of whom report a “poor” understanding of orthopaedics. Furthermore, the majority of UK doctors are not exposed to orthopaedics at the postgraduate level, which only serves to amplify the disparity between junior and generalist knowledge, and the standards expected by senior colleagues and professional bodies. Conclusion. There is a deficit in undergraduate orthopaedic training within the UK which has only worsened in the last 20 years, leaving medical students and foundation doctors with a potentially significant lack of orthopaedic knowledge.

Simulation use in training is rapidly becoming a mainstay educational tool seen to offer perceived benefits of a safe environment for repeated practice and learning from errors without jeopardising patient safety. However, there is currently little evidence addressing the trainees’ perspectives and attitudes of simulation training, particularly in comparison with trainers and the educational community. This study investigates orthopaedic trainees’ and trainers’ conceptions of learning from simulation-based training, exploring whether the orthopaedic community are ‘on the same page’, with respect to each other and the educational community. Qualitative research in the form of semi-structured interviews is used to identify commonalities and differences between trainee and trainer conceptions, based on respective experiences and expectations, and suggests ways of enhancing collaboration between stakeholders to achieve better alignment of conceptions. The research revealed that orthopaedic trainees and trainers conceive key themes in a similar manner: supporting the role of simulation in developing the ‘pre-trained novice’ as opposed to skill refinement or maintenance; attributing greater importance to non-technical rather than technical skills development using simulation; questioning the transferability to practice of learnt skills; and emphasising similar barriers to increased curriculum integration, including financing and scheduling. These conceptions are largely in contrast to those of the educational community, possibly due to differing conceptions of learning between the two communities, along with a lack of a common language in the discourse of simulation. There was some evidence of changing attitudes and positively emerging conceptions among the orthopaedic community, and capitalising on this by engaging trainers and trainees may help reconcile the differing conceptions and facilitate increasing simulation utilisation and curriculum integration. Developing a common language to make the educational more tangible to surgeons, bringing the educational closer to the surgical, may help maximise the educational benefit and shape the future of simulation use in surgical training

Abstract. Introduction. Challenges in surgical training have led to the exploration of technologies such as augmented reality (AR), which present novel approaches to teaching orthopaedic procedures to medical students. The aim of this double-blinded randomised-controlled trial was to compare the validity and training effect of AR to traditional teaching on medical students’ understanding of total knee arthroplasty (TKA). Methodology. Twenty medical students from 7 UK universities were randomised equally to either intervention or control groups. The control received a consultant-led teaching session and the intervention received training via Microsoft HoloLens, where surgeons were able to project virtual information over physical objects. Participants completed written knowledge and practical exams which were assessed by 2 orthopaedic consultants. Training superiority was established via 4 quantitative outcome measures: OSATS scores, a checklist of TKA-specific steps, procedural time, and written exam scores. Qualitative feedback was evaluated using a 5-point Likert scale. Results. AR training was superior in teaching basic technical proficiency and understanding of TKA, with the intervention group significantly outperforming the control group in 3 metrics [OSATS (38.6%, p=0.021), checklist (33%, p=0.011) and written exam (54.5%, p=0.001)]. Procedural time was equivalent between cohorts (p=0.082). AR was rated as significantly more enjoyable (p=0.044), realistic (p=0.003), easy to understand (p=0.040), and proficient in teaching (p=0.02). Conclusion. In this adequately powered, double-blinded randomised-controlled trial, AR training demonstrated substantially improved translational technical skills and knowledge needed to understand TKA over traditional learning in medical students. Additionally, the results showed face, content, and transfer validity for AR in surgical training

The COVID-19 pandemic has disrupted all segments of daily life, with the healthcare sector being at the forefront of this upheaval. Unprecedented efforts have been taken worldwide to curb this ongoing global catastrophe that has already resulted in many fatalities. One of the areas that has received little attention amid this turmoil is the disruption to trainee education, particularly in specialties that involve acquisition of procedural skills. Hand surgery in Singapore is a standalone combined programme that relies heavily on dedicated cross-hospital rotations, an extensive didactic curriculum and supervised hands-on training of increasing complexity. All aspects of this training programme have been affected because of the cancellation of elective surgical procedures, suspension of cross-hospital rotations, redeployment of residents, and an unsustainable duty roster. There is a real concern that trainees will not be able to meet their training requirements and suffer serious issues like burnout and depression. The long-term impact of suspending training indefinitely is a severe disruption of essential medical services. This article examines the impact of a global pandemic on trainee education in a demanding surgical speciality. We have outlined strategies to maintain trainee competencies based on the following considerations: 1) the safety and wellbeing of trainees is paramount; 2) resource utilization must be thoroughly rationalized; 3) technology and innovative learning methods must supplant traditional teaching methods; and 4) the changes implemented must be sustainable. We hope that these lessons will be valuable to other training programs struggling to deliver quality education to their trainees, even as we work together to battle this global catastrophe

Abstract. Source of Study: London, United Kingdom. This intervention study was conducted to assess two developing protocols for quadriceps and hamstring rehabilitation: Blood Flow Restriction (BFR) and Neuromuscular Electrical Stimulation Training (NMES). BFR involves the application of an external compression cuff to the proximal thigh. In NMES training a portable electrical stimulation unit is connected to the limb via 4 electrodes. In both training modalities, following device application, a standardised set of exercises were performed by all participants. BFR and NMES have been developed to assist with rehabilitation following lower limb trauma and surgery. They offer an alternative for individuals who are unable to tolerate the high mechanical stresses associated with traditional rehabilitation programmes. The use of BFR and NMES in this study was compared across a total of 20 participants. Following allocation into one of the training programmes, the individuals completed training programmes across a 4-week period. Post-intervention outcomes were assessed using Surface Electromyography (EMG) which recorded EMG amplitude values for the following muscles: Vastus Medialis, Vastus Lateralis, Rectus Femoris and Semitendinosus. Increased Semitendinosus muscle activation was observed post intervention in both BFR and NMES training groups. Statistically significant differences between the two groups was not identified. Larger scale randomised-controlled trials are recommended to further assess for possible treatment effects in these promising training modalities

Superior teamwork in the operating theatre is associated with improved technical performance and clinical outcomes. Yet modern rota patterns, workforce shortages, and increasing complexity of surgery, means that there is less familiarity between staff and the required choreography. Immersive Virtual Reality (iVR) can successfully train surgical staff individually, however iVR team training has yet to be investigated. We aimed to design a multiplayer iVR platform for anterior approach total hip arthroplasty (AA-THA) and assess if multiplayer iVR training was superior to single player training for acquisition of both technical and non-technical skills. An iVR platform with choreographed roles for the surgeon and scrub nurse was developed using Cognitive Task Analysis. Forty participants were randomised to individual or team iVR training. Individually- trained participants practiced alongside virtual avatar counterparts, whilst teams trained live in pairs. Both groups underwent five iVR training sessions over 6-weeks. Subsequently, they underwent a real-life assessment in which they performed AA-THA on a high-fidelity model with real equipment in a simulated theatre. Teams performed together and individually trained participants were randomly paired up. Videos were marked by two blinded assessors recording the NOTSS, NOTECHS II and SPLINTS scores - validated technical and non-technical scores assessing surgeon and scrub nurse skills. Secondary outcomes were procedure time and number of technical errors. Teams outperformed individually trained participants for non-technical skills in the real-world assessment (NOTSS 13.1 ± 1.5 vs 10.6 ± 1.6, p =0.002, NOTECHS-II score 51.7 ± 5.5 vs 42.3 ± 5.6, p=0.001 and SPLINTS 10 ± 1.2 vs 7.9 ± 1.6, p = 0.004). They completed the assessment 28.1% faster (27.2 minutes ± 5.5 vs 41.8 ±8.9, p<0.001), and made fewer than half the number of technical errors (10.4 ± 6.1 vs 22.6 ± 5.4, p<0.001). Multiplayer training leads to faster surgery with fewer technical errors and the development of superior non-technical skills for anterior approach total hip arthroplasty. The convention of surgeons and nurses training separately, but undertaking real complex surgery together, can be supplanted by team training, delivered through immersive virtual reality

Superior team performance in surgery leads to fewer technical errors, reduced mortality, and improved patient outcomes. Scrub nurses are a pivotal part of this team, however they have very little structured training, leading to high levels of stress, low confidence, inefficiency, and potential for harm. Immersive virtual reality (iVR) simulation has demonstrated excellent efficacy in training surgeons. We tested the efficacy of an iVR curriculum for training scrub nurses in performing their role in an anterior approach total hip arthroplasty (AA-THA). Sixty nursing students were included in this study and randomised in a 1:1 ratio to learning the scrub nurse role for an AA-THA using either conventional training or iVR. The training was derived through expert consensus with senior surgeons, scrub nurses and industry reps. Conventional training consisted of a 1-hour seminar and 2 hours of e-learning where participants were taught the equipment and sequence of steps. The iVR training involved 3 separate hour-long sessions where participants performed the scrub nurse role with an avatar surgeon in a virtual operation. The primary outcome was their performance in a physical world practical objective assessment with real equipment. Data were confirmed parametric using the Shapiro-Wilk test and means compared using the independent samples student's t-test. 53 participants successfully completed the study (26 iVR, 27 conventional) with a mean age of 31±9 years. There were no significant differences in baseline characteristics or baseline knowledge test scores between the two groups (p>0.05). The iVR group significantly outperformed the conventionally trained group in the real-world assessment, scoring 66.9±17.9% vs 41.3±16.7%, p<0.0001. iVR is an easily accessible, low cost training modality which could be integrated into scrub nursing curricula to address the current shortfall in training. Prolonged operating times are strongly associated with an increased risk of developing serious complications. By upskilling scrub nurses, operations may proceed more efficiently which in turn may improve patient safety

The Ontario Crippled Children's Centre has completed a two-year research project designed to develop effective strategies for training the preschool child to use a myoelectric prosthesis. Two programmes were developed: one home-based with the parent as primary trainer, and the other Centre-based with a therapist as trainer. Seventeen children were successfully trained and fitted with myoelectric prostheses. Both training programmes appear to be equally effective, proving that informed parents can assume responsibility for the training of their children. Economic implications are self-evident. The functional assessment of the children's skill with the myoelectric prosthesis is very encouraging so far. However, long-term studies are indicated for adequate assessment of the cost-effectiveness of early myoelectric fitting. As a result of this study, effective training methods can now be used in routine clinical service; a manual is available to provide guidelines

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

Aims. Total hip arthroplasties (THAs) are performed by surgeons at various stages in training with varying levels of supervision, but we do not know if this is safe practice with comparable outcomes to consultant-performed THA. Our aim was to examine the association between surgeon grade, the senior supervision of trainees, and the risk of revision following THA. Methods. We performed an observational study using National Joint Registry (NJR) data. We included adult patients who underwent primary THA for osteoarthritis, recorded in the NJR between 2003 and 2016. Exposures were operating surgeon grade (consultant or trainee) and whether or not trainees were directly supervised by a scrubbed consultant. Outcomes were all-cause revision and the indication for revision up to ten years. We used methods of survival analysis, adjusted for patient, operation, and healthcare setting factors. Results. We included 603,474 THAs, of which 58,137 (9.6%) procedures were performed by a trainee. There was no association between surgeon grade and all-cause revision up to ten years (crude hazard ratio (HR) 1.00 (95% confidence interval (CI) 0.94 to 1.07); p = 0.966), a finding which persisted with adjusted analysis. Fully adjusted analysis demonstrated an association between trainees operating without scrubbed consultant supervision and an increased risk of all-cause revision (HR 1.10 (95% CI 1.00 to 1.21); p = 0.045). There was an association between trainee-performed THA and revision for instability (HR 1.14 (95% CI 1.01 to 1.30); p = 0.039). However, this was not observed in adjusted models, or when trainees were supervised by a scrubbed consultant. Conclusion. Within the current training system in England and Wales, appropriately supervised trainees achieve comparable THA survival to consultants. Trainees who are supervised by a scrubbed consultant achieve superior outcomes compared to trainees who are not supervised by a scrubbed consultant, particularly in terms of revision for instability.

We present an evaluation of basic surgical orthopaedic operative training in the last 15 years, using multiple trauma and elective training procedures in orthopaedics. Identifying the influence of competency training and EWTD on Basic Surgical Training. Whilst trying to identify the area’s the MMC should concentrate on to provide a competent trainng programme. We assessed clinical exposure using 45 Basic Surgical Trainee Logbooks, from posts in 1990 (n=6), 1995 (n=7), 2000 (n=10), and 2004–5 (n=22); and looked at numbers of carpel tunnel decompression, and emergency hip, wrist, and ankle surgeries conducted. As well as the number of external fixators trainees were exposed to. In the 2004–5 group we prospectively assessed competency and knowledge of fracture neck of femur surgery. From a peak in operative surgery in 1990 numbers have fallen. Today, BST’s participate in 165 emergency hip cases (mean 4.6 procedures per trainee), today, 4.8% (n=8) as primary surgeon. In 1990, and 2000 trainees were primary surgeon in 43.4% (n = 12/32) and 25.2% (n=33/131) respectively. Trainees are comfortable with closure of skin, subcutaneous and muscular layers but not access; 91% (n=20) required assistance in positioning, and reduction, and recognition of correct alignment. Only 9.1% (n=2) felt competent without senior supervision (mean Orthopaedic BST experience 15.3 months) in hip surgery; whilst none knew of an intra-operative technique to reduce young adult capsular hip fractures. With regards to wrist and ankle fixation the decline has been dramatic decline by 11.1 and 5.9 procedures per trainee. Whilst, the numbers of forearm manipulations peaked in 1990–1995; it has since dropped to less than 5 per trainee in 2005 from 15–16. In 2005, it was also seen that a in a 6 month period a trainee in a typical district general hospital would be lucky to see an external fixator applied (average 0.6 per trainee in 6 month period). The decline of elective surgery is shown in carpel tunnel decompressions attended. In 1990 9.8 (6–14) were conducted as a primary operator, in 2005, it was 0.5 (0–3). The greatest decline in procedures of 46.3% occurred between 2000, to 2005. A comparison of total operating showed 88.9 (n=79–125) procedures in 6 months were lost between 1990 and 2005; with a 58.6% loss in trauma. This study suggests deficiency in operative competence today due to reduced opportunities. Thus emphasis should be placed on rota’s being matched to operative exposure, as trainee case numbers have declined sharply particularly in the last 5 years. The MMC should therefore ensure that trainees in the ST1 to 3 years reach their competencies with adequate time in the operating theatre

Abstract. Introduction. Knee arthroscopy can be used for ligamentous repair, reconstruction and to reduce burden of infection. Understanding and feeling confident with knee arthroscopy is therefore a highly important skillset for the orthopaedic surgeon. However, with limited training or experience, furthered by reduced practical education due to COVID-19, this skill can be under-developed amongst trainee surgeons. Methods. At a single institution, ten junior doctors (FY1 to CT2), were recruited as a part of a five, two-hour session, training programme utilising the Simbionix® ARTHRO Mentor knee arthroscopy simulator, supplemented alongside educational guidance with a consultant orthopaedic knee surgeon. All students had minimal to no levels of prior arthroscopic experience. Exercises completed included maintaining steadiness, image centering and orientation, probe triangulation, arthroscopic knee examination, removal of loose bodies, and meniscectomy. Pre and post-experience questionnaires and quantitative repeat analysis on simulation exercises were undertaken to identify levels of improvement. Results. Comparing pre and post-experience questionnaires significant improvements in levels of confidence were noted in the following domains: naming arthroscopic instruments, port positioning and insertion, recognising normal anatomy arthroscopically, holding and using arthroscopic instruments and assisting in a live theatre setting (p<0.05). Significant improvements were noted in time taken to complete, distance covered in metres and roughness of instruments used on the simulated exercises on repeat performance (p<0.05). Conclusion. With only five sessions under senior guidance, using a simulator such as the ARTHRO Mentor, significant improvements in both levels of confidence and skill can be developed even among individuals with no prior experience

This qualitative study aims to explore and highlight the experiences of trainees in the Orthopaedic Surgical Education Training (SET) program in New Zealand, with a focus on identifying gender-specific biases which may impact professional development. Orthopaedic SET trainees in New Zealand were invited to complete a qualitative, semi-structured questionnaire exploring their experiences in the Orthopaedic SET program. A broad range of topics were covered, addressing culture, belonging, learning styles and role modelling. Recurrent themes were identified using inductive methods. Analysis of questionnaire responses identified several key themes for women in the Orthopaedic SET program, compared to their male counterparts, including (1) role incredulity, (2) confidence vs. competence, (3) adaptation, (4) interdisciplinary relationships and (5) role modelling. Female participants described experiencing gender bias or discrimination by both patients and interdisciplinary colleagues at a higher rate than their male counterparts. The majority of female participants described feeling as competent as their male counterparts at the same SET level, however, identified that they do not typically exhibit the same confidence in their surgical abilities. Whilst similar numbers of female and male participants described experiencing barriers to career progression, female participants described having to adapt both physically and socially to overcome additional gender-specific barriers. Positive influences on training experience included role modelling and supportive relationships amongst trainee groups. This study highlighted gender-specific biases experienced by trainees in the Orthopaedic SET program in New Zealand. Further investigation is warranted to determine how these experiences affect professional development, and how they may be addressed to foster increased gender equity in the surgical profession. This will likely require system-level interventions to create meaningful and sustainable culture change

Introduction and Aim. Quadriceps strength is crucial for physical function in patients with knee osteoarthritis (KOA). This study aimed to investigate the effect of combining blood flow restriction (BFR) with low-intensity training (LIT) on quadricep strength in patients with advanced KOA. Methods. Patients with advanced KOA were block randomized by gender into the control or BFR group. The control group received LIT with leg press (LP) and knee extension (KE) at 30% of 1-repetition maximum (1-RM), while the BFR group underwent the same training with 70% limb occlusion. Physical function and patient-reported outcomes were assessed up to 16 weeks. Results. A total of 42 patients were analyzed: 22 in the BFR group (9 males, 13 females) and 20 in the control group (8 males, 12 females). In the BFR group, males exhibited increased KE power from the 4th to the 16th week (p<0.05) and LP power from the 4th to the 12th week (p<0.05). Females in the BFR group showed increased KE power in the 4th and 12th weeks (p<0.05), and LP power increased from the 4th to the 16th week (p<0.05). Males also had improved TSS at the 12th week, while females had improved TSS from the 8th to the 16th week. In the control group, males did not experience an increase in quadricep power. Females, however, had increased KE power in the 4th, 12th, and 16th weeks (p<0.05), and LP power from the 4th to the 12th week (p<0.05). Females in the control group also had improved TSS at the 4th week. Patient-reported outcomes did not differ, and all patients tolerated the training without any dropouts or adverse events. Conclusion. Combining BFR with LIT significantly improved quadricep power and physical function in both genders of KOA patients without exacerbating symptoms

Surgical trainees are finding it increasingly more challenging to meet operative requirements and coupled with the effects of COVID-19, we face a future of insufficiently trained surgeons. As a result, virtual reality (VR) simulator training has become more prevalent and whilst more readily accepted in certain arthroscopic fields, its use in hip arthroscopy (HA) remains novel. This project aimed to validate VR high-fidelity HA simulation and assess its functional use in arthroscopic training. Seventy-two participants were recruited to perform two basic arthroscopic tasks on a VR HA simulator, testing hip anatomy, scope manipulation and triangulation skills. They were stratified into novice (39) and experienced (33) groups based on previous arthroscopy experience. Metric parameters recorded from the simulator were used to assess construct validity. Face validity was evaluated using a Likert-style questionnaire. All recordings were reviewed by 2 HA experts for blinded ASSET score assessment. Experienced participants were significantly faster in completing both tasks compared with novice participants (p<0.001). Experienced participants damaged the acetabular and femoral cartilage significantly less than novice participants (p=0.011) and were found to have significantly reduced path length of both camera and instrument across both tasks (p=0.001, p=0.007), demonstrating significantly greater movement economy. Total ASSET scores were significantly greater in experienced participants compared to novice participants (p=0.041) with excellent correlation between task time, cartilage damage, camera and instrument path length and corresponding ASSET score constituents. 62.5% of experienced participants reported a high degree of realism in all facets of external, technical and haptic experience with 94.4% advising further practice would improve their arthroscopic skills. There was a relative improvement of 43% in skill amongst all participants between task 1 and 2 (p<0.001). This is the largest study to date validating the use of simulation in HA training. These results confirm significant construct and face validity, excellent agreement between objective measures and ASSET scores, significant improvement in skill with continued use and recommend VR simulation to be a valuable asset in HA training for all grades

Abstract. Objectives. Non-technical skills including teamwork play a pivotal role in surgical outcomes. Virtual reality is effective at improving technical skills, however there is a paucity of evidence on team-based virtual reality (VR) training. This study aimed to assess if multiplayer virtual reality training was superior to solo training for acquisition of both technical and non-technical skills in learning the complex anterior approach total hip arthroplasty operation. Methods. 10 novice surgeons and 10 novice scrub nurses, were randomised to solo or team virtual reality training to perform anterior approach total hip arthroplasty. Solo participants trained with virtual avatar counterparts, whilst teams trained in pairs (surgeon and scrub nurse). Both groups underwent 5 VR training sessions over 6 weeks. Then, they underwent a real-life assessment in which they performed AA-THA on a high-fidelity model with real equipment in a simulated operating theatre. Teams performed together and solo participants were randomly paired up with a solo player of the opposite role. Videos of the assessment were marked by two blinded expert assessors. Outcomes were procedure time, procedural errors from an expert pre-defined protocol and acetabular component positioning. Non-technical skills were assessed using the NOTECHs II and NOTSS scores. Results. Teams were 28.11% faster than solos in the real world assessment (31.22 minutes ±2.02 vs 43.43 ±2.71, p=0.01), with 34.91% less errors (−15.25 errors ±3.09 vs −23.43 ±1.84, p=0.04). Teams had significantly higher NOTSS and NOTECHS II scores when compared to solos (p<0.001). 8/10 surgeons placed the acetabular component within the target safe zone. Conclusions. Multiplayer training appears to lead to faster surgery with fewer technical errors and the development of superior non-technical skills. VR learnt skills appear to translate to the physical world. This supports the application of multidisciplinary learning to create a more integrated approach to surgical team training

Abstract. Objectives. Evidence supporting the use of immersive virtual reality (iVR) training in orthopaedic procedures is rapidly growing. However, the impact of the timing of delivery of this training is yet to be tested. This study investigated whether spaced iVR training is more effective than massed iVR training for novices learning hip arthroplasty. Methods. 24 medical students with no hip arthroplasty experience were randomised to learning total hip arthroplasty using the same iVR simulation training either once-weekly or once-daily for four sessions. Participants underwent a baseline physical world assessment to orientate an acetabular component on a saw bone pelvis, and a baseline knowledge test. In iVR, we recorded procedural errors, time, numbers of prompts required and path lengths of the hands and head across 4 sessions. To assess skill retention, the iVR and baseline physical world assessments were repeated at one-week and one-month. Results. Baseline characteristics between the groups were comparable (p > 0.05). The daily group demonstrated faster skills acquisition, reducing the mean number of procedural errors from 76.8±37.5 (S1) to 11.1±10.1 (S4), compared to the weekly group improvement from 71.1±19.1 (S1) to 17.2±10.6 (S4), p < 0.001. The weekly group error count plateaued remaining at 16±6.7 at 1-week and 17.5±8.5 at one-month, the daily group however, showed poor retention with error counts rising to 17.8±10.5 at 1 week and becoming higher than the weekly group at one-month to (23.2±13.0 vs 17.5±10.5). A similar effect was noted for procedural time and the number of assistive prompts. In the real-world assessment, both groups significantly improved the accuracy of their acetabular component positioning, these improvements were equally maintained. Conclusions. Daily iVR training facilitates faster skills acquisition, however weekly practice has superior skills retention. Skills learnt using both regimes demonstrate sustained transfer to the real-world

Orthopaedic training sessions, vital for surgeons to understand post-operative joint function, are primarily based on passive and subjective joint assessment. However, cadaveric knee simulators, commonly used in orthopaedic research,. 1. could potentially benefit surgical training by providing quantitative joint assessment for active functional motions. The integration of cadaveric simulators in orthopaedic training was explored with recipients of the European Knee Society Arthroplasty Travelling Fellowship visiting our institution in 2018 and 2019. The aim of the study was to introduce the fellows to the knee joint simulator to quantify the surgeon-specific impact of total knee arthroplasty (TKA) on the dynamic joint behaviour, thereby identifying potential correlations between surgical competence and post-operative biomechanical parameters. Eight fellows were assigned a fresh-frozen lower limb each to plan and perform posterior-stabilised TKA using MRI-based patient-specific instrumentation. Surgical competence was adjudged using the Objective Structured Assessment of Technical Skills (OSATS) adapted for TKA. 2. All fellows participated in the in vitro specimen testing on a validated knee simulator,. 3. which included motor tasks – passive flexion (0°-120°) and active squatting (35°-100°) – and varus-valgus laxity tests, in both the native and post-operative conditions. Tibiofemoral kinematics were recorded with an optical motion capture system and compared between native and post-operative conditions using a linear mixed model (p<0.05). The Pearson correlation test was used to assess the relationship between the OSATS scores for each surgeon and post-operative joint kinematics of the corresponding specimen (p<0.05). OSATS scores ranged from 79.6% to 100% (mean=93.1, SD=7.7). A negative correlation was observed between surgical competence and change in post-operative tibial kinematics over the entire range of motion during passive flexion – OSATS score vs. change in tibial abduction (r=−0.87; p=0.003), OSATS score vs. change in tibial rotation (r=−0.76; p=0.02). When compared to the native condition, post-operative tibial internal rotation was higher during passive flexion (p<0.05), but lower during squatting (p<0.033). Post-operative joint stiffness was greater in extension than in flexion, without any correlation with surgical competence. Although trained at different institutions, all fellows followed certain standard intraoperative guidelines during TKA, such as achieving neutral tibial abduction and avoiding internal tibial rotation,. 4. albeit at a static knee flexion angle. However, post-operative joint kinematics for dynamic motions revealed a strong correlation with surgical competence, i.e. kinematic variability over the range of passive flexion post-TKA was lower for more skilful surgeons. Moreover, actively loaded motions exhibited stark differences in post-operative kinematics as compared to those observed in passive motions. In vitro testing on the knee simulator also introduced the fellows to new quantitative parameters for post-operative joint assessment. In conclusion, the inclusion of cadaveric simulators replicating functional joint motions could help quantify training paradigms, thereby enhancing traditional orthopaedic training, as was also the unanimous opinion of all participating fellows in their positive feedback

Brazilian jiu-jitsu (BJJ) is a grappling-based martial art which can lead to injuries both in training and in competitions. There is a paucity of data regarding injuries sustained while training in Brazilian jiu-jitsu both in competitive and non-competitive jiu-jitsu athletes. Our primary objective was to determine the prevalence of injuries sustained during jiu-jitsu training and competition. Our secondary objectives were to describe the types of injuries, and to determine which participant and injury characteristics are associated with desire to discontinue jiu-jitsu following injury, and characteristics are associated with requiring surgery for an injury. We conducted a survey of all BJJ participants at one club in Hamilton Ontario. We developed a questionnaire using focus groups, key informants and the previous literature. The questionnaire included questions on demographics, injuries in competition and/or training, treatment received, and whether the participant considered discontinuing BJJ following injury. The primary analysis was descriptive. The secondary analysis consisted of unadjusted logistic regression analyses to evaluate the association between selected demographic and injury patterns and those who considered quitting jiu-jitsu as a result of their injuries as a dependent variable. Seventy BJJ athletes participated in this study (response rate 85%). The majority of respondents were male (90%), over the age of 30 years (58.6%), and junior trainees (white belts [37.2%] or blue belts [42.9%]). Ninety one percent of participants were injured in training and 60% of competitive athletes were injured in competitions. Significantly more injuries were sustained overall (p < 0 .001) for each body region (p∼0.001) in training in comparison to competition. Two-thirds of injured participants required medical attention, with 15% requiring surgery. Participants requiring surgical treatment were six and a half times more likely to consider quitting compared to those requiring other treatments, including no treatment (OR: 6.50, 95% CI: 1.53–27.60). Participants required to take more than four months off training were five and a half times more likely to consider quitting compared to those who took less time off (OR: 5.48, 95% CI: 2.25–13.38). We identified that nine out of ten jiu-jitsu practitioners surveyed suffered injury while in training and the most severe injuries for the majority of practitioners occurring during training. The most common injuries identified involved the fingers, neck, knee, and shoulder, with the majority of respondents seeking medical or surgical treatment or requiring physiotherapy or rehabilitation. Potential participants in BJJ should be informed regarding significant risk of injury and instructed regarding appropriate precautions and safety protocols. BJJ practitioners and instructors should be especially cognizant of safety during training, where the majority of injuries occur

Aims. The aim of this study is to determine the effects of the UK lockdown during the COVID-19 pandemic on the orthopaedic admissions, operations, training opportunities, and theatre efficiency in a large district general hospital. Methods. The number of patients referred to the orthopaedic team between 1 April 2020 and 30 April 2020 were collected. Other data collected included patient demographics, number of admissions, number and type of operations performed, and seniority of primary surgeon. Theatre time was collected consisting of anaesthetic time, surgical time, time to leave theatre, and turnaround time. Data were compared to the same period in 2019. Results. There was a significant increase in median age of admitted patients during lockdown (70.5 (interquartile range (IQR) 46.25 to 84) vs 57 (IQR 27 to 79.75); p = 0.017) with a 26% decrease in referrals from 303 to 224 patients and 37% decrease in admissions from 177 to 112 patients, with a significantly higher proportion of hip fracture admissions (33% (n = 37) vs 19% (n = 34); p = 0.011). Paediatric admissions decreased by 72% from 32 to nine patients making up 8% of admissions during lockdown compared to 18.1% the preceding year (p = 0.002) with 66.7% reduction in paediatric operations, from 18 to 6. There was a significant increase in median turnaround time (13 minutes (IQR 12 to 33) vs 60 minutes (IQR 41 to 71); p < 0.001) although there was no significant difference in the anaesthetic time or surgical time. There was a 38% (61 vs 38) decrease in trainee-led operations. Discussion. The lockdown resulted in large decreases in referrals and admissions. Despite this, hip fracture admissions were unaffected and should remain a priority for trauma service planning in future lockdowns. As plans to resume normal elective and trauma services begin, hospitals should focus on minimising theatre turnaround time to maximize theatre efficiency while prioritizing training opportunities. Clinical relevance. Lockdown has resulted in decreases in the trauma burden although hip fractures remain unaffected requiring priority. Theatre turnaround times and training opportunities are affected and should be optimised prior to the resumption of normal services. Cite this article: Bone Joint Open 2020;1-8:494–499

Introduction and Objective. Over the past few years, a reorganization of the educational pathways has been promoted with the purpose of optimizing the acquisition of competences and their assessment, so as to reduce the risks to both health care professionals and end users. Virtual reality (VR) has been repeatedly tested, initially as a positive reinforcement for more traditional educational pathways and, more recently, as their potential substitute. The aim of this study was to demonstrate the potentiality of VR simulation training in spine surgery. Materials and Methods. The VR simulator reproduced the lateral lumbar access to the spine. The simulation included a tutorial, the preoperative settings, and the surgical session with different levels of procedural complexity. A total of 10 users were recruited for this study: 3 senior surgeons (group A) and 7 orthopedic residents or junior orthopedic surgeons (group B). Each user completed the simulation twice. Results. The user's age or previous experience with VR technology did not show any relevance. On average, the entire simulation was completed in 24 minutes and 36 seconds. Group B showed an improvement between the 2 attempts in both sessions, the preoperative settings and the surgical simulation. The number of major errors dropped from an average of 5.2 to 1.8 and from an average of 4 (1–6) to 1.4, respectively. The simulation was never interrupted because of technical bugs or adverse effects related to the technology. Conclusions. VR-based training pathways might promote a high standard of care. Our preliminary experience suggests an effective implementation of the traditional coaching process

Aims. Rotator cuff muscle atrophy and fatty infiltration affect the clinical outcomes of rotator cuff tear patients. However, there is no effective treatment for fatty infiltration at this time. High-intensity interval training (HIIT) helps to activate beige adipose tissue. The goal of this study was to test the role of HIIT in improving muscle quality in a rotator cuff tear model via the β3 adrenergic receptor (β3AR). Methods. Three-month-old C57BL/6 J mice underwent a unilateral rotator cuff injury procedure. Mice were forced to run on a treadmill with the HIIT programme during the first to sixth weeks or seventh to 12th weeks after tendon tear surgery. To study the role of β3AR, SR59230A, a selective β3AR antagonist, was administered to mice ten minutes before each exercise through intraperitoneal injection. Supraspinatus muscle, interscapular brown fat, and inguinal subcutaneous white fat were harvested at the end of the 12th week after tendon tear and analyzed biomechanically, histologically, and biochemically. Results. Histological analysis of supraspinatus muscle showed that HIIT improved muscle atrophy, fatty infiltration, and contractile force compared to the no exercise group. In the HIIT groups, supraspinatus muscle, interscapular brown fat, and inguinal subcutaneous white fat showed increased expression of tyrosine hydroxylase and uncoupling protein 1, and upregulated the β3AR thermogenesis pathway. However, the effect of HIIT was not present in mice injected with SR59230A, suggesting that HIIT affected muscles via β3AR. Conclusion. HIIT improved supraspinatus muscle quality and function after rotator cuff tears by activating systemic sympathetic nerve fibre near adipocytes and β3AR.

There is no unified national training system for orthopaedic surgeons in China. With such rapid progress in many aspects of life in China, there is an imminent need for improvement in the training of orthopaedic specialists. Since 2003 the orthopaedic community in Hong Kong has been working in collaboration with their colleagues in mainland China to develop a training system for orthopaedic surgery. We adopted the system from the Royal College of Surgeons of Edinburgh (RCSEd), setting up a trial centre in the Beijing Jishuitan hospital in 2006, with trainers and trainees attaining the standards set by RCSEd and the Hong Kong College of Orthopaedic Surgeons (HKCOS). This trial is ongoing, with the success of two trainees who passed the exit examination in 2010 and became the first Chinese orthopaedic surgeons with a joint fellowship of both the RCSEd and the HKCOS. Following this inaugural success, we are confident that China will develop a training system for orthopaedic surgeons to a consistently high international standard

The Postgraduate Medical Education and Training Board wants either ‘run through’ or ‘uncoupled’ orthopaedic training to be adopted throughout the United Kingdom but it is not willing to let both continue together as is the current situation. This annotation explores the argument for and against ‘run through’ training

In order to assess the efficacy of inspection and accreditation by the Specialist Advisory Committee for higher surgical training in orthopaedic surgery and trauma, seven training regions with 109 hospitals and 433 Specialist Registrars were studied over a period of two years. There were initial deficiencies in a mean of 14.8% of required standards (10.3% to 19.2%). This improved following completion of the inspection, with a mean residual deficiency in 8.9% (6.5% to 12.7%.) Overall, 84% of standards were checked, 68% of the units improved and training was withdrawn in 4%. Most units (97%) were deficient on initial assessment. Moderately good rectification was achieved but the process of follow-up and collection of data require improvement. There is an imbalance between the setting of standards and their implementation. Any major revision of the process of accreditation by the new Post-graduate Medical Education and Training Board should recognise the importance of assessment of training by direct inspection on site, of the relationship between service and training, and the advantage of defining mandatory and developmental standards

Background. Revision total knee arthroplasty (rTKA) is a high stakes procedure with complex equipment and multiple steps. For rTKA using the ATTUNE system revising femoral and tibial components with sleeves and stems, there are over 240 pieces of equipment that require correct assembly at the appropriate time. Due to changing teams, work rotas, and the infrequency of rTKR, scrub nurses may encounter these operations infrequently and often rely heavily on company representatives to guide them. In turn, this delays and interrupts surgical efficiency and can result in error. This study investigates the impact of a fully immersive virtual reality (VR) curriculum on training scrub nurses in technical skills and knowledge of performing a complex rTKA, to improve efficiency and reduce error. Method. Ten orthopaedic scrub nurses were recruited and trained in four VR sessions over a 4-week period. Each VR session involved a guided mode, where participants were taught the steps of rTKA surgery by the simulator in a simulated operating theatre. The latter 3 sessions involved a guided mode followed by an unguided VR assessment. Outcome measures in the unguided assessment were related to procedural sequence, duration of surgery and efficiency of movement. Transfer of skills was assessed during a pre-training and post-training assessment, where participants completed multi-step instrument selection and assembly using the real equipment. A pre and post-training questionnaire assessed the participants knowledge, confidence and anxiety. Results. All participants reported orthopaedics as their primary speciality with mean of 6-years experience. 80% reported they are ‘sometimes’ required to scrub for operations in which they do not feel comfortable with the equipment. All participants improved across the 3 unguided sessions reducing their operative time by 47%, assistive prompts by 75%, dominant hand motion by 28% and head motion by 36%. This transferred into the real-world: Participants completed 11.3% of tasks correctly in pre-training compared to 83.5% correct in the timely selection and assembly of rTKA equipment, post-training. All participants reported increased confidence and reduced anxiety after the training. Conclusion. Unfamiliarity with orthopaedic procedures or equipment is common for scrub nurses and can impact surgical performance. VR training improves their understanding, technical skills and efficiency in complex rTKA. These VR-learnt skills translate into the physical environment. This has important implications on how scrub nurses can be trained remotely, asynchronously and safely to perform complex orthopaedic surgery

There are significant differences in the methods and styles of orthopaedic surgical training between continents, all with the aim to produce competent consultant surgeons, but the differences in training content and pathway are vast. We review and contrast the key differences between three continents

Conventional fracture courses utilise prefabricated sawbones that are not realistic or patient specific. The aim of this study is to determine the feasibility of creating 3D fracture models and utilising them in fracture courses to teach surgical technique. We selected an AO type 2R3C2 fracture that underwent open reduction internal fixation. De-identified CT scan images were converted to a stereolithography (STL) format. This was then processed using Computer Aided Design (CAD) to create a virtual 3D model. The model was 3D printed using a combination of standard thermoplastic polymer (STP) and a porous filler to create a realistic cortical and cancellous bone. A case-based sawbone workshop was organised for residents, unaccredited registrars, and orthopaedic trainees comparing the fracture model with a prefabricated T-split distal radius fracture. Pre-operative images aided discussion of fixation, and post-operative x-rays allowed comparison between the participants fixation. Participants were provided with identical reduction tools. We created a questionnaire for participants to rate their satisfaction and experience using a Likert scale. The 3D printed fracture model aided understanding and appreciation of the fracture pattern and key fragments amongst residents and unaccredited trainees. Real case-based models provided a superior learning experience and environment to aid teaching. The generic sawbone provided easier drilling and inserting of screws. Preliminary results show that the cost of 3D printing can be comparable to generic sawbones. It is feasible to create a fracture model with a real bone feel. Further research and development is required to determine the optimum material to use for a more realistic feel. The use of 3D printed fracture models is feasible and provides an alternative to generic sawbone fracture models in providing surgical training to residents

Despite being one of the most common orthopaedic operations, it is still not known how many arthroscopies of the knee must be performed during training in order to develop the skills required to become a Consultant. A total of 54 subjects were divided into five groups according to clinical experience: Novices (n = 10), Junior trainees (n = 10), Registrars (n = 18), Fellows (n = 10) and Consultants (n = 6). After viewing an instructional presentation, each subject performed a simple diagnostic arthroscopy of the knee on a simulator with visualisation and probing of ten anatomical landmarks. Performance was assessed using a validated global rating scale (GRS). Comparisons were made against clinical experience measured by the number of arthroscopies which had been undertaken, and ROC curve analysis was used to determine the number of procedures needed to perform at the level of the Consultants. There were marked differences between the groups. There was significant improvement in performance with increasing experience (p < 0.05). . ROC curve analysis identified that approximately 170 procedures were required to achieve the level of skills of a Consultant. . We suggest that this approach to identify what represents the level of surgical skills of a Consultant should be used more widely so that standards of training are maintained through the development of an evidenced-based curriculum.

Training time in Trauma & Orthopaedics is pressured. In this action research project, we develop a feedback/self-reflection model for trainers and trainees, emphasising the contribution both groups make to training, to maximise cohesion and efficacy. Starting in 2013, trainees completed anonymous feedback forms after each 6-month post. The 18-point quantitative questionnaire covers four training domains: WBA engagement, teaching/feedback, research/audit, operative training. Consultant trainers completed a once-off corresponding 18-point self-reflection questionnaire. Additionally, trainers were asked for their expectations of and advice for trainees. Individual trainer profiles were generated from trainee feedback questionnaires, allowing comparison between trainer-group-average, trainer-specific and trainer-self-reflection scores across 18 fields. Trainer profiles were uploaded to ISCP and used for recognition of trainer status for SOAR. This data provided basis for local service provision review with amendments to maximise training efficacy. Results of thematic analysis of trainer feedback was shared with the trainee group. This and subsequent group self-reflection formed the basis of our ‘Trainee Charter’. Trainee feedback illustrates high levels of satisfaction with local training (average global score 4.2/5). Strengths included ‘feedback’ and ‘operative teaching’; relative weaknesses included ‘research time’ and ‘OPD teaching’. The ‘Trainee Charter’ details specific desirable behaviours that embody eight trainee-qualities consistently identified by trainers as important, including ‘honesty’ and ‘being organised’. The charter emphasises trainee contribution to training. For the first time, trainers have the benefit of serial and individualised feedback. Trainees are better informed and empowered in relation to maximising their own training. Most importantly, both halves of the training-team are explicitly acknowledged

Background. For total hip arthroplasty (THA), cognitive training prior to performing real surgery may be an effective adjunct alongside simulation to shorten the learning curve. This study sought to create a cognitive training tool to perform direct anterior approach THA, validated by expert surgeons; and test its use as a training tool compared to conventional material. Methods. We employed a modified Delphi method with four expert surgeons from three international centres of excellence. Surgeons were independently observed performing THA before undergoing semi-structured cognitive task analysis (CTA) before completing successive rounds of electronic surveys until consensus. The agreed CTA was incorporated into a mobile and web-based platform. Forty surgical trainees (CT1-ST4) were randomised to CTA-training or a digital op-tech with surgical videos, before performing a simulated DAA THA in a validated fully-immersive virtual reality simulator. Results. Experts reached 100% consensus after five rounds. They defined THA in 46 steps and 52 decision points in 8 distinct procedural phases. Each phase comprised of a set of actions, cognitive demands, and critical errors and strategies. This CTA was mapped onto an open-access web-based learning tool [1]. Surgeons who prepared with CTA performed a simulated THA more efficiently (Time: 26 vs. 36 minutes and Procedural steps: 64 vs. 78), with fewer errors in instrument selection (22 vs 34 instances) and help required (6 vs. 19 instances), and with more accuracy (acetabular cup inclination error: 7° vs. 12°, anteversion error: 11° vs 19°) than those who prepared with conventional material. Discussion. This is the first validated CTA tool for arthroplasty. It provides structure for competency-based learning of this complex procedure. It is more effective at preparing orthopaedic trainees for a new procedure than conventional materials, for learning sequence, instrumentation and motor skills. Implications. Cognitive training combines education on decision making, knowledge and technical skill. It is a validated educational tool to upskill surgeons to perform hip arthroplasty and could replace current training and preparation methods for junior surgeons

Background. Virtual Reality (VR) uses headsets and motion-tracked controllers so surgeons can perform simulated total hip arthroplasty (THA) in a fully-immersive, interactive 3D operating theatre. The aim of this study was to investigate the effect of laboratory-based VR training on the ability of surgical trainees to perform direct anterior approach THA on cadavers. Methods. Eighteen surgical trainees (CT1-ST4) with no prior experience of direct anterior approach (DAA) THA completed an intensive 1-day course (lectures, dry-bone workshops and technique demonstrations). They were randomised to either a 5-week protocol of VR simulator training or conventional preparation (operation manuals and observation of real surgery). Trainees performed DAA-THA on cadaveric hips, assisted by a passive scrub nurse and surgical assistant. Performance was measured on the Intercollegiate Surgical Curriculum Project (ISCP) procedure-based assessment (PBA), on a 9-point global summary score (Table 1). This was independently assessed by 2 hip surgeons blinded to group allocation. The secondary outcome measure was error in cup orientation from a predefined target (40° inclination and 20° anteversion). Results. Surgeons trained using VR performed a cadaveric DAA-THA significantly better than those using conventional preparation, as assessed by acetabular cup orientation (p<0.001) and using the ISCP-PBA. Two VR surgeons achieved Level 3b, 6 were graded at Level 3a, and 1 was graded at Level 2b. Six non-VR surgeons achieved Level 2a and 3 were graded at Level 1b. Discussion. These data demonstrate transfer of procedural knowledge and psychomotor skills learnt from VR to a real-world setting. Conventional preparation had limited value for novice surgeons learning arthroplasty. VR training advanced them further up the learning curve. Implications. Virtual reality can augment surgical training for open procedures in orthopaedics curve, so opportunities in real surgery can be maximised. This has implications for how surgical training is delivered for surgeons learning a new, complex procedure. For any figures or tables, please contact the authors directly

Purpose of study. To evaluate implementation of the Back Skills Training (BeST) programme in clinical practice within the National Health Service (NHS). Background. The BeST programme is a group Cognitive Behavioural Approach (CBA) for people with persistent (≥6 weeks) low back pain (LBP). This intervention has been shown to be clinically and cost-effective in a large pragmatic trial. To aid implementation of the BeST programme, an online training intervention (iBeST) was developed. Methods. iBest was promoted through marketing activities (e.g. conferences, social media, evidence briefs) prior to release and launched in March 2016 for NHS health care professionals. Impact of iBeST is being evaluated by measuring number enrolled, course completion, implementation intention, clinical delivery, perceived competence, attitudes/beliefs towards LBP, knowledge and satisfaction. Data is collected at pre and post-training, 4 months and 12 months after course completion. A service evaluation is also being conducted to measure clinical impact. Patients taking part in the BeST programme as part of routine treatment complete questionnaires at baseline, post-treatment, 3 months and 12 months after the programme to assess pain, disability, recovery, satisfaction and usefulness of BeST. Results. 881 clinicians have enrolled on iBeST and 260 have completed training (target: 250). 28 NHS sites are delivering the BeST programme. 385 and 290 participants have provided baseline and post treatment data respectively (target: 400). Data collection is ongoing. Conclusion. Implementation is challenging but iBeST has been well received by NHS clinicians and we plan to report further results of the impact and service evaluation.
