With the drawdown from Afghanistan focus turns towards future operations, and their demands on the DMS. Training for surgeons deploying to military operations will have to take into account the decreased opportunities and experience gained by current conflicts. The aim is to focus on current UK surgical training for military operations specifically. A comparison is made with US surgical training. A questionnaire was distributed to UK military surgical consultants in General Surgery, Trauma and Orthopaedics and Plastic Surgery. A similar questionnaire was sent to deployed US surgeons in SE Afghanistan. Response rates of 55% were achieved. Respondents were questioned on their confidence to perform several key procedures. Most UK consultants were satisfied with their overall training for deployment. Satisfaction rates were high for the MOST course and Danish Surgery. US satisfaction with pre-deployment training was poor. The majority of respondents felt confident to perform all haemorrhage and contamination control procedures in an emergency. However, most felt training for military personnel should be lengthened by a year or more to include greater exposure to other specialties. Whilst satisfaction with surgical training is high, many UK surgeons appear to suggest an increase in specialty exposure in preparation for future deployments

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

Skills simulation is increasingly used as a training tool in postgraduate surgical training. Trainee's perception of the value of this experience has not previously been investigated. Our aim was to investigate the value of surgical simulation training delivered by an arthroscopy skills course. We constructed a subject-specific, self-assessment questionnaire based around the ISCP Peer Assessment Tool. The questionnaire was administered to candidates before and after attending the Plymouth Arthroscopy Skills Course. Participant demographic data was recorded. Questionnaire data was interrogated to give an overview of the course, as well as the benefit of site-specific skills stations. Statistical analysis showed the data to be normally distributed. The paired T-test was used to compare mean values. Twelve surgical trainees attended the course – CT2 trainees (n=4); ST3 trainees (n=7); ST4 trainee (n=1). 11 candidates completed both administered questionnaires giving a 92% response rate. The global mean score at the beginning of the course was 2.39. The global mean score at the end of the course was 3.90. The mean improvement was 1.51 (p<0.01; 95% CI = 0.96–2.07). Skill station specific scores all showed improvement with the greatest effect in wrist arthroscopy. CT trainees had a lower mean score compared to ST trainees. Both groups completed the course with similar mean scores. This study shows that arthroscopy simulation improves trainee-reported ratings of surgical skill. It also shows that less experienced candidates derived the greatest benefit from the training. Further research is required to compare self-assessed performance against objective benchmarks using validated assessment tools

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. Visual representation help make the ever-increasing data more attractive, thought provoking and informative. In the field of surgical training, Procedure Based Assessment is a structured method of assessing surgical performance and skills of trainees in the UK and is a valuable tool for trainers in the Annual Review of Competence Progression. Trainers can view PBA's on the online-based Intercollegiate Surgical Curriculum Programme individually in a long-form format with no visual representation. Aim. To assess the effect of an originally devised EVR tool of PBA's in the context of ARCP on 10 aspects including speed of assessment, assimilation of data, ease of interpretation and identification of trainees’ weaknesses and strengths. Methodology. 1) ISCP PBA data collected for three volunteered specialty trainees (ST4, ST5 & ST6) enrolled in Warwick Trauma and Orthopaedic training programme, for a six-month period from 1st July 2013 till 31st December 2013. 2) An EVR was generated using Tableau Desktop software, and two other EVR's originally devised to visually represent the trainees’ PBA's and integrated into three interactive PDF files. 3) Twelve trainer consultants participated in a mock ARCP and rated their experience in assessing the trainee's using the new EVR method compared to the ISCP website on three surveys. 4) A mock ARCP was set up for 12 consultants. To minimise bias, six assessors were randomised into two equal groups. Groups A were asked to use the ISCP website to formulate an ARCP decision and then use the EVR interactive tool. Group B used the EVR tool followed by browsing the ISCP website. 5) Assessors rated their experience after using each method and also at the end of the mock ARCP on three surveys. Responses recorded on a Visual Analogue Scale and statistically analysed using non-parametric a two-tailed Mann Whitney U test. Results. Comparing responses to the EVR and ISCP surveys shows that users thought that using the EVR tool is more useful, accessible, easy to learn and use, time efficient and appealing. It also allowed them to better identify trainees’ areas of strengths and weaknesses and formulate a final ARCP outcome decision in relation to PBA's (p < 0.001). Strong agreement to develop the EVR tool and have incorporated into the current ISCP website have been demonstrated (p < 0.001). Comparison of total responses to the EVR and ISCP surveys between group A and group B showed no significant statistical difference. Conclusion. The project shows that Enhanced Visual Representation tool has the potential to be a positive addition to the ISCP website to improve the process of surgical training and feedback

Introduction: Most surgeons agree on basic parameters defining a successful joint replacement procedure. However, the process of acquiring the skills to achieve this level of success on a reproducible basis is much less straightforward. In reality, it is generally not possible to impart surgical training without some level of risk to the patient, particularly if a particular trainee or procedure has a long learning curve. In an attempt to address these issues, we have developed a new computer-based training system to measure the technical results of hip and knee replacement surgery in both the operating room and the Bioskills Lab. Description of the System: This system utilizes Surgical Navigation technology combined with data analysis and display routines to monitor the position and alignment of instruments and implants during the procedure in comparison with a preoperative plan. For bioskills training, the surgeon develops a preoperative plan on a computer workstation using accurate 3D computer models of the bones and appropriate implants. The surgeon then performs the entire procedure using the cadaver or sawbone model. During the procedure, the position and orientation of the bones, each surgical instrument, and the trial components are measured with a three-dimensional motion analysis system. Through analysis of this data, the surgeon is able to view each step of the surgical procedure, the placement of each instrument with respect to each bone, and the consequences of each surgical decision in terms of the final placement of the prosthetic components When errors are detected in the implementation of the preoperative plan, the surgeon is able to replay each step of the procedure to examine the precise placement of each instrument with respect to each bone and the consequences of each surgical decision in terms of leg length, alignment and range-of-motion. Conclusions: This system allows us to measure the technical success of a surgical procedure in terms of quantifiable geometric, spatial, kinematic or kinetic parameters. It also provides postoperative feedback to the surgeon by demonstrating the specific contributions of each step of the surgical procedure to deviations in final alignment or soft tissue instability. This approach allows surgeons to be trained outside the operating room prior to patient exposure. Once these skills have been developed, the surgeon is able to operate freely in the operating room without the risks associated with traditional surgical training, or the expense associated with intraoperative Surgical Navigation. The value of this approach in the training and accreditation of orthopedic staff warrants further investigation

Background. Hip fractures affect 1.6 million people globally per annum, associated with significant morbidity and mortality. A large proportion are extracapsular neck of femur fractures, treated with the dynamic hip screw (DHS). Mechanical failure due to cut-out is seen in up to 7% of DHS implants. The most important predictor of cut-out is the tip-apex distance (TAD), a numerical value of the lag screw”s position in the femoral head. This distance is determined by the psychomotor skills of the surgeon guided by fluoroscopic imaging in theatre. With the current state of surgical training, it is harder for junior trainees to gain exposure to these operations, resulting in reduced practice. Additionally, methods of simulation using workshop bones do not utilise the imaging component due to the associated radiation risks. We present a digital fluoroscopy software, FluoroSim, a realistic, affordable, and accessible fluoroscopic simulation tool that can be used with workshop bones to simulate the first step of the DHS procedure. Additionally, we present the first round of accuracy tests with this software. Methods. The software was developed at the Royal National Orthopaedic Hospital, London, England. Two orthogonally placed cameras were used to track two coloured markers attached to a DHS guide-wire. Affine transformation matrices were used in both the anterior-posterior (AP) and cross table lateral (CTL) planes to match three points from the camera image of the workshop bone to three points on a pre-loaded hip radiograph. The two centre points of each marker were identified with image processing algorithms and utilised to digitally produce a line representing the guide-wire on the two radiographs. To test the accuracy of the system, the software generated 3D guide-wire apex distance (GAD) (from the tip of the guide-wire to a marker at the centre of calibration) was compared to the same distance measured with a digital calliper (MGAD). In addition, the same accuracy value was determined in a simulation scenario, from 406 attempts by 67 medical students. Results. The median absolute inaccuracy of FluoroSim with 270 measurements was 3.35mm (IQR = [1.15mm, 6.53mm]). The absolute inaccuracy showed a graded increase the further away the tip of the guide-wire was from the centre of calibration; MGAD ≤10mm, median absolute inaccuracy = 1.53mm; MGAD 10mm<x≤20mm, median absolute inaccuracy = 4.97mm; MGAD >20mm, median absolute inaccuracy = 7.23mm. Comparison between all three groups reached significance (p < 0.001). In a simulation scenario with medical students, FluoroSim had a significantly greater median absolute inaccuracy of 4.79mm compared to the testing scenario (p < 0.001). Conclusion. FluoroSim is a safe and inexpensive digital imaging adjunct to workshop bones simulation. To our knowledge this technology has not been explored in the context of DHS simulation, and has the potential to be extended to other orthopaedic procedures

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.

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.

Anterior approach total hip arthroplasty (AA-THA) has a steep learning curve, with higher complication rates in initial cases. Proper surgical case selection during the learning curve can reduce early risk. This study aims to identify patient and radiographic factors associated with AA-THA difficulty using Machine Learning (ML).

Consecutive primary AA-THA patients from two centres, operated by two expert surgeons, were enrolled (excluding patients with prior hip surgery and first 100 cases per surgeon). K- means prototype clustering – an unsupervised ML algorithm – was used with two variables - operative duration and surgical complications within 6 weeks - to cluster operations into difficult or standard groups.

Radiographic measurements (neck shaft angle, offset, LCEA, inter-teardrop distance, Tonnis grade) were measured by two independent observers. These factors, alongside patient factors (BMI, age, sex, laterality) were employed in a multivariate logistic regression analysis and used for k-means clustering. Significant continuous variables were investigated for predictive accuracy using Receiver Operator Characteristics (ROC).

Out of 328 THAs analyzed, 130 (40%) were classified as difficult and 198 (60%) as standard. Difficult group had a mean operative time of 106mins (range 99–116) with 2 complications, while standard group had a mean operative time of 77mins (range 69–86) with 0 complications. Decreasing inter-teardrop distance (odds ratio [OR] 0.97, 95% confidence interval [CI] 0.95–0.99, p = 0.03) and right-sided operations (OR 1.73, 95% CI 1.10–2.72, p = 0.02) were associated with operative difficulty. However, ROC analysis showed poor predictive accuracy for these factors alone, with area under the curve of 0.56. Inter-observer reliability was reported as excellent (ICC >0.7).

Right-sided hips (for right-hand dominant surgeons) and decreasing inter-teardrop distance were associated with case difficulty in AA-THA. These data could guide case selection during the learning phase. A larger dataset with more complications may reveal further factors.

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.

Global surgical literature suggests that female trainees have less operative autonomy than their male counterparts. This pilot study had the primary objective to identify difference in autonomy by gender, and to power a national study to carry out further quantitative and qualitative research on this.

This was a retrospective, cross-sectional study utilising eLogbook data for all orthopaedic trainees (ST2-8) and consultants with CCT date 2016–2021 in a single Scottish deanery. The primary outcome measure was percentage of procedures undertaken as lead surgeon. 15 trainees and four recent consultants participated, of which 12 (63%) were male (mean grade 5.2), and 7 (37%) were female (mean grade 4.3). Trainees were lead surgeon on 64% of procedures (17595/27558), with autonomy rising with grade (37% ST1 to 85% ST8, OR 9.4). Operative autonomy was higher in male vs female trainees (66.5% and 61.4% respectively, p=<0.0001), with female trainees more likely to operate with a supervisor present (STU/S vs P/T, f 48%:13%, m 45%:20%).

This pilot study found that there was a significant difference in operative autonomy between male and female trainees, however this may be explained by differences in mean grade of male vs female trainees. Five trainees took time OOT, 4/5 of whom were female. Extension to a national multi-centre study should repeat the quantitative method of this study with additional qualitative analysis including assessing effect of time OOT to explore the reason for any gender discrepancies seen across different deaneries in the UK.

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

Computer assisted navigation (CAN) has been shown to significantly improve the overall alignment obtained after total knee arthroplasty (TKA). Human error and the use of conventional jigs may be the reasons for the inaccuracy of conventional TKA. The impact of computer assisted equipment in surgeon training has not yet been established. Three orthopaedic trainees participated in this prospective study to assess the impact of CAN upon intraoperative alignment. Each trainee’s first five (early group) and last five (late group) TKA’s were included in the study during their three month training period. A total of 30 patients were included in the study. The accuracy of conventional jig positioning was assessed simultaneously using navigation equipment. After this assessment, the actual bony resection was performed using CAN equipment. There was a consistent trend towards improved accuracy between the early and late groups in the majority of parameters assessed. In the early group, the coronal plane tibial alignment was found to be outside the acceptable three degree range in 11 out of 15. In the late group this improved to two out of 15 (p< 0.05). An average of 2.8 degrees of tibial jig deviation during pinning was noted in the early group which improved to one degree in late group. The accuracy of jig placement in both groups was improved by CAN. Computer assisted navigation is helpful in improving the accuracy of trainee surgeons and should prove a useful adjunct in training. Surgical accuracy using conventional jig based systems can be improved with training. Deviation of conventional tibial alignment jig during pinning is a significant factor. This aspect has not been appreciated fully in the past and can be minimised by the use of the navigation equipment. As shown in previous studies, the overall alignment using CAN is superior to what would have been obtained using conventional jigs for TKA

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

Background

Hip fractures cause significant morbidity and mortality, affecting 70,000 people in the UK each year. The dynamic hip screw (DHS) is used for the osteosynthesis of extracapsular neck of femur fractures, a procedure that requires complex psychomotor skills to achieve optimal lag screw positioning. The tip-apex distance (TAD) is a measure of the position of the lag screw from the apex of the femoral head, and is the most comprehensive predictor of cut-out (failure of the DHS construct). To develop these skills, trainees need exposure to the procedure, however with the European Working Time Directive, this is becoming harder to achieve. Simulation can be used as an adjunct to theatre learning, however it is limited. FluoroSim is a digital fluoroscopy simulator that can be used in conjunction with workshop bones to simulate the first step of the DHS procedure (guide-wire insertion) using image guidance. This study assessed the construct validity of FluoroSim. The null hypothesis stated that there would be no difference in the objective metrics recorded from FluoroSim between users with different exposure to the DHS procedure.

Methods

This multicentre study recruited twenty-six orthopaedic doctors. They were categorised into three groups based on the number of DHS procedures they had completed as the primary surgeon (novice <10, intermediate 10≤x<40 and experienced ≥40). Twenty-six participants completed a single DHS guide-wire attempt into a workshop bone using FluoroSim. The TAD, procedural time, number of radiographs, number of guide-wire retires and cut-out rate (COR) were recorded for each attempt.

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).
