Abstract
Background: Simulation models enable learners to have repeated practise at their own time, to master the psycho-motor and sensory acuity aspects of surgery and build their confidence in the procedure. The study aims to develop and evaluate the feasibility of a low-cost drilling model to train surgeons in the drilling task. The model targets three aspects of drilling - (1) Reduce plunge depth, (2) Ability to differentiate between bone and medullary canal and (3) Increase accuracy drilling in various angles. Methods: This cross-sectional study was conducted after obtaining ethics approval. We invited Consultants in the field of Orthopaedic or Hand Surgery to form the 'expert' group, and the 'novice' group consisted of participants who had no prior experience in bone drilling. We developed a drilling simulator model made from a polyvinyl chloride (PVC) pipe filled with liquid silicone. This model cost less than US$5. An electric Bosch drill (model GBM 10 RE) with a 1.4 mm K-wire 10 cm in length (6.5 cm outside the drill) was used for drilling. The main outcomes of the study were time taken for drilling, plunge depth, ability to penetrate the far cortex and accuracy. Results: Thirty-one participants were recruited into the study, of which 15 were experts and 16 were novices. The experts performed significantly better for plunge depth (t = -3.65, p = 0.0003) and accuracy (t = -2.07, p = 0.04). The experts required 20% less time to complete the drilling tasks, but it was not statistically significant (t = -0.79, p = 0.43). Conclusions: The low-cost drilling model could be useful in training Residents in the drilling task. It will allow Residents to practise independently at their own time and assess their own performance.

Abstract
INTRODUCTION Although placement of a distal femoral traction (DFT) pin is a relatively simple procedure used to stabilize femoral and pelvic fractures, it places patients at risk of iatrogenic vascular, muscular, or bony injury. We designed and implemented an educational module combining theory and practical experience to standardize and improve resident teaching on the placement of DFT pins. METHODS We introduced a DFT pin teaching module into our second-year resident "boot camp," which is used to help prepare residents for taking primary call in the emergency department at our level I trauma center. Nine residents participated. The teaching module included a written pretest, an oral lecture, a video demonstration of the procedure, and a practice simulation on 3D printed models. After completing the teaching, each resident underwent a written examination and proctored live simulation involving 3D models using the same equipment available in our emergency department. Pre-teaching and post-teaching surveys were used to assess resident experience and confidence with placing traction in the emergency department. RESULTS Before the teaching session, the rising postgraduate year 2 residents scored an average of 62.2% (range, 50% to 77.8%) on the DFT pin knowledge quiz. This improved to an average of 86.6% (range, 68.1% to 100%) (P = 0.0001) after the teaching session. After completing the educational module, they also demonstrated an improvement in confidence with the procedure, from 6.7 (range, 5 to 9) to 8.8 (range, 8 to 10) (P = 0.04). DISCUSSION Despite reporting high levels of confidence in their ability to place traction pins before starting the postgraduate year 2 consult year, many residents also reported anxiety around the accurate placement of traction pins. Early results of our training program showed improved resident knowledge of safe placement of traction pins and improved confidence with the procedure.

Abstract
The purpose of this study is to propose a quantitative assessment scheme to help with surgical bone drilling training. This pilot study gathered and compared motion and force data from expert surgeons (n = 3) and novice residents (n = 6). The experiment used three-dimensional printed bone simulants of young bone (YB) and osteoporotic bone (OB), and drilling overshoot, time, and force were measured. There was no statistically significant difference in overshoot between the two groups (p = 0.217 for YB and 0.215 for OB). The results, however, show that the experts took less time (mean = 4.01 s) than the novices (mean = 9.98 s), with a statistical difference (p = 0.003 for YB and 0.0001 for OB). In addition, the expert group performed more consistently than the novices. The force analysis further revealed that experts used a higher force to drill the first cortical section and a noticeably lower force in the second cortex to control the overshoot (approximate reduction of 5.5 N). Finally, when drilling time and overshoot distance were combined, the motion data distinguished the skill gap between expert and novice drilling; the force data provided insight into the drilling mechanism and performance outcomes. This study lays the groundwork for a data-driven training scheme to prepare novice residents for clinical practice.

Abstract
Bone drilling is a critical skill honed during orthopaedic surgical education. How a bone drill is held and operated (bracing position) may influence drilling performance. Methods A prospective study with randomized crossover was conducted to assess the effect of 4 bracing positions on orthopaedic surgical trainee performance in a simulated bone drilling task. Linear mixed effects models considering participant training level, preferred bracing position, height, weight, and drill hole number were used to estimate pairwise and overall comparisons of the effect of each bracing position on 2 primary outcomes of drilling depth and accuracy. Results A total of 42 trainees were screened and 19 were randomized and completed the study. Drill plunge depth with a 1-handed drilling position was significantly greater by pairwise comparison to any of the 3 double handed positions tested: a soft tissue protection sleeve in the other hand (0.41 mm, 95% confidence interval [CI] 0.80-0.03, p = 0.031), a 2-handed position with the contralateral small finger on bone and the thumb on the drill (0.42 mm, 95% CI 0.06-0.79, p = 0.018), and a 2-handed position with the contralateral elbow braced against the table (0.40 mm, 95% CI 0.02-0.78, p = 0.038). No position afforded a significant accuracy advantage (p = 0.227). Interactions of participant height with plunge depth and accuracy as well between drill hole number and plunge depth were observed. Conclusion Orthopaedic surgical educators should discourage trainees from operating a bone drill using only 1 hand to reduce the risk of iatrogenic injury due to drill plunging.

Abstract
BACKGROUND Simulation is among the tools used in France to train residents specialising in orthopaedic and trauma surgery (OTS). However, implementing simulation-based training (SBT) is complex and poorly reported. The objective of this study was to describe the use of simulation for OTS training in France. HYPOTHESIS Nationwide, SBT is not used to its full capacity for teaching OTS in France, and differences in opinions about SBT may exist between surgeon educators and residents. STUDY DESIGN Nationwide questionnaire survey in France. MATERIALS AND METHODS We built two specific self-questionnaires then e-mailed them between December 2020 and February 2021 to the surgeon educators who were members of the national university council and to the residents specialising in OTS during the current academic year. The questions were about the 2018-2019 academic year, before the COVID-19 pandemic. Two classes of residents who were still medical students during this period were not included, leaving three classes for the analysis. RESULTS The participation rates were 57% (67/117) for the educators and 24% (87/369) for the three classes of residents. Of the 67 educators, 47 (70%) reported being involved in SBT and identified the university (70%) and industry (53%) as the main funders of this teaching modality. The educators indicated that the mean number of SBT laboratories in their region was 1.4±0.9 (range, 0-4). The main types of simulators were saw bones (77%); cadavers (85%); and commercial simulators (74%), notably for the knee (87%) and shoulder (78%). The educators estimated that they had achieved a mean of 33%±23% (range, 0%-100%) of the teaching objectives set out in the OTS curriculum and that the main obstacles were insufficient funding (81%) and lack of time (67%). Only 21% of educators reported conducting SBT research. The residents reported that they accessed SBT via the OTS teaching module (28/87, 32%), local university degrees (23/87, 26%), their hospital department (17/87, 18%), or the industry (15/87, 17%); 25/87 (29%) had never received SBT. On a 0-10 scale (0, completely disagrees; 10, completely agrees), the mean score for SBT effectiveness was 8.6±2.1 for residents and 7.1±3.0 for educators (p<0.001); the corresponding values for the quality of SBT integration in the region were 1.5±1.8 and 3.8±2.6, respectively (p<0.001). CONCLUSION SBT is not yet used to its full potential for teaching OTS in France. Insufficient funding and lack of time were identified by the educators as the main obstacles to greater use of SBT. Both the residents and the educators felt that SBT mightbe beneficial for training. LEVEL OF EVIDENCE IV, nationwide survey.

Abstract
PURPOSE To identify and appraise evidence assessing the effectiveness of low-fidelity arthroscopic simulation in the acquisition of arthroscopic surgical skills in a novice population. METHODS Four databases were electronically searched in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) algorithm. Studies from any year that described the use of orthopaedic, low-fidelity arthroscopic training models in novice populations were included. Questionnaires, case studies, and review studies were excluded. Risk of bias assessment was conducted using the Cochrane Collaboration's Risk of Bias Tool or the Cochrane Risk of Bias in Non-Randomised Studies of Interventions (ROBINS-I) checklist. RESULTS Sixteen studies were identified. Using the PRISMA algorithm, 6 studies were included with a total of 131 novice participants. Individual studies ranged from 8 to 40 novices and were of Level I to II evidence. Outcome measurements varied between studies (total 16 different outcomes used). Various outcome measures used for assessing arthroscopic surgical skills within all 6 studies demonstrated significant improvement. A cross-study subjective outcome synthesis revealed low-fidelity arthroscopic simulators reduced time to completion outcomes (2 studies, P < .05), increased Arthroscopic Surgical Skill Evaluation Tool scores (2 studies, P < .01), and confirmed face validity (2 studies) and transfer of skills to cadavers (2 studies) or live patients (1 study). Cost data were under-reported in all studies apart from one. CONCLUSIONS Arthroscopic training using low-fidelity simulators likely improves the performance of novice participants in completing basic arthroscopic procedures. These simulators may also be more cost effective and thus more implementable than their high-fidelity counterparts. LEVEL OF EVIDENCE Level II, systematic review of Level I-II studies.

Abstract
BACKGROUND Robust assessment of skills acquisition and surgical performance during training is vital to ensuring operative competence among orthopaedic surgeons. A move to competency-based surgical training requires the use of tools that can assess surgical skills objectively and systematically. The aim of this systematic review was to describe the evidence for the utility of assessment tools used in evaluating operative performance in trauma and orthopaedic surgical training. METHODS We performed a comprehensive literature search of MEDLINE, Embase, and Google Scholar databases to June 2019. From eligible studies we abstracted data on study aim, assessment format (live theater or simulated setting), skills assessed, and tools or metrics used to assess surgical performance. The strengths, limitations, and psychometric properties of the assessment tools are reported on the basis of previously defined utility criteria. RESULTS One hundred and five studies published between 1990 and 2019 were included. Forty-two studies involved open orthopaedic surgical procedures, and 63 involved arthroscopy. The majority (85%) were used in the simulated environment. There was wide variation in the type of assessment tools in used, the strengths and weaknesses of which are assessor and setting-dependent. CONCLUSIONS Current technical skills-assessment tools in trauma and orthopaedic surgery are largely procedure-specific and limited to research use in the simulated environment. An objective technical skills-assessment tool that is suitable for use in the live operative theater requires development and validation, to ensure proper competency-based assessment of surgical performance and readiness for unsupervised clinical practice. CLINICAL RELEVANCE Trainers and trainees can gain further insight into the technical skills assessment tools that they use in practice through the utility evidence provided.

Abstract
Introduction Senior medical students learn trauma principles in a 90-min interactive teaching session based on the trauma evaluation and management module designed by the American College of Surgeons. However, the number of surgical faculty available to conduct these interactive small group sessions is limited. The goal of this study is to compare the effectiveness of surgical residents to that of surgical faculty in teaching trauma principles. Methods 53 senior medical students received trauma teaching from trauma faculty ( n = 22), trauma residents ( n = 21), or no teaching ( n = 10). Students were tested on cognitive trauma knowledge (20 multiple choice questions) and clinical trauma simulation (using objective structured clinical performance score). All students completed a 5-point subjective questionnaire. Results Students receiving trauma teaching outperformed students receiving no teaching in the knowledge test (mean 13.0 ± 3.6 standard deviation (SD) vs. 8.4 ± 2.4 SD, p < 0.05), while faculty and resident teaching outcomes were similar (mean 12.6 ± 3.0 SD vs. 13.4 ± 4.1, p = 0.45). Similarly, in the clinical trauma simulation, students receiving trauma teaching scored better (objective score mean 78% vs. 56%, p < 0.05), while there was no difference between faculty and resident teaching outcomes (objective score mean 77% vs. 80%, p = 0.52). In the subjective questionnaire, students who received trauma teaching rated themselves higher on a scale of 10 in trauma knowledge and skills than those who did not have formal teaching (mean 5.2 vs. 2.1, p < 0.05) as resident and attending teaching group ratings were similar. Conclusions Although small group discussions and increased simulation enhance undergraduate surgical trauma education, the number of faculty surgeons needed to fully incorporate these activities is limited. Objective and perceived effectiveness of teaching trauma management by surgical residents compared to trauma attendings is equivalent. This highlights the opportunity to incorporate residents into teaching roles to bridge the gap in undergraduate trauma education.

Abstract
PURPOSE The purpose of this study was to develop and perform the initial validation for the Surgical Training and Educational Platform (STEP), a cost-effective psychomotor training and assessment instrument designed to teach and evaluate fundamental skills considered critical to competency in hand surgery. METHODS An American Society for Surgery of the Hand (ASSH) taskforce of 13 board-certified hand surgeons developed 8 skills considered fundamental to competency in hand surgery including: (1) lag screw fixation of an oblique fracture, (2) depth of plunge during bicortical drilling, (3) central axis scaphoid fixation, (4) phalangeal fracture pinning, (5) flexor tendon repair, (6) microsurgical suturing, (7) full-thickness skin graft harvest, and (8) wrist arthroscopy. The tasks were developed from commercially available, nonclinical supplies at low cost. The startup cost for the entire system was less than $600 USD, with a cost-per-trainee-assessment of approximately $25 USD. After the tasks were finalized, 2 examiners traveled to 8 sites around the country to evaluate 93 surgeons, including 57 board-certified hand surgeons and 36 first-year orthopedic and plastic surgical residents. Scoring criteria for each task were based on a combination of time and clinically relevant quality metrics. RESULTS Board-certified hand surgeons significantly outperformed surgical trainees on all 8 tasks, demonstrating that the STEP appropriately differentiates the skill level of expert and novice hand surgeons. CONCLUSIONS The STEP is an effective simulator that encompasses a wide range of fundamental psychomotor skills considered critical to competency in hand surgery. Although the STEP tasks are a valuable surgical training tool, further work is required to evaluate and refine the scoring system prior to using it as a critical evaluation of performance. CLINICAL RELEVANCE The STEP simulator is a valuable, validated instrument for resident and fellow education and evaluation in hand surgery outside of the operating room.

Abstract
PURPOSE OF REVIEW As immersive learning outside of the operating room is increasingly recognized as a valuable method of surgical training, virtual reality (VR) and augmented reality (AR) are increasingly utilized in orthopedic surgical training. This article reviews the evolving nature of these training tools and provides examples of their use and efficacy. The practical and ethical implications of incorporating this technology and its impact on both orthopedic surgeons and their patients are also discussed. RECENT FINDINGS Head-mounted displays (HMDs) represent a possible adjunct to surgical accuracy and education. While the hardware is advanced, there is still much work to be done in developing software that allows for seamless, reliable, useful integration into clinical practice and training. Surgical training is changing: AR and VR will become mainstays of future training efforts. More evidence is needed to determine which training technology translates to improved clinical performance. Volatility within the HMD industry will likely delay advances in surgical training.

Abstract
BACKGROUND Simulation-based training is one way to improve basic competence for surgical trainees and thus improve patient safety. Closed reduction and percutaneous pinning of a supracondylar humerus fracture is a common procedure that encompasses many basic orthopaedic skills and has been identified as a residency milestone. Despite this, no quantitative tools exist to help learners attain this basic skill. This study seeks to validate a quantitative, low-cost simulation-based training tool for teaching orthopaedic surgery trainees the fundamentals of fracture stabilization with pins. METHODS Two low-cost models were developed with simulated cancellous bone blocks and cortical bone sheets: a pinning agility tool to teach pin placement and redirection, and a low-cost construct stability tool to replicate pinning. A high-cost construct stability tool was cut using a pediatric supracondylar humerus model to simulate pinning a real fracture. Construct stability was assessed by adding weight until ∼1.6 mm of displacement was observed. Participants were tested naively on all 3 models and then completed a training session using only the low-cost models. Performance following training was then assessed and compared with fellowship-trained pediatric orthopaedic surgeons. Participants also rated their preintervention and postintervention confidence, skill, and knowledgeability. RESULTS A total of 18 novice trainees participated (10 PGY1 and PGY2 orthopaedic surgery residents and 8 medical student members of the orthopaedic surgery interest club), whereas the reference group consisted of 7 orthopaedic surgery attendings. The subjects significantly improved their scores on both the low-cost (P=0.002) and high-cost (P<0.001) construct stability tools after the training with only the low-cost tools. Compared with the attending benchmark, trainee scores improved on the high-fidelity model from 31% preintervention to 86% postintervention and their pinning times decreased by 38%. Trainees reported increased knowledge, skill, and confidence after the intervention (P<0.001). CONCLUSIONS A novel, low-cost simulation model and training session for supracondylar humerus fracture pinning resulted in improved performance in stabilizing a supracondylar humerus model and increased trainee knowledgeability, confidence, and skill. LEVEL OF EVIDENCE Level II-economic.

Abstract
PURPOSE The purpose of this study is to provide an overview of the published literature on the existing educational methods used to teach surgical skills, with a specific focus on hip surgery, to orthopaedic residents. METHODS A total of 31 articles were selected from a PubMed literature search on the topic of teaching surgical skills to orthopaedic residents, and 9 articles on hip surgery are included in this review. RESULTS Although several methods are included in the published literature to teach orthopaedic residents, only arthroscopy of the knee and shoulder joint is well described. Hip arthroscopy has a steeper learning curve and thus the use of simulation training as a complementary teaching method is even more important. CONCLUSIONS Currently, open surgery skills for joint arthroplasty are largely acquired by apprenticeship learning. Simulation training in the form of virtual reality could contribute to better performance of residents, decreasing operation time and improving patient safety.

Abstract
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.

Abstract
PURPOSE Vibratory and acoustic feedback, drill sharpness, and material density have each been shown to influence the depth of plunging when drilling through bicortical bone. We hypothesized that drilling technique can also influence the depth of plunging. METHODS Six subjects of various training levels (PGY1 to 16-year experienced surgeon) were asked to drill through a cortical bone surrogate, third-generation Sawbones tube with similar density and compressive modulus of healthy cortical bone. Using a sharp 4.5-mm drill bit and System 6 drill, each participant drilled 30 holes wearing surgical gloves to mimic tactile feedback and using 3 different techniques (10 holes each). The techniques were single-handed smooth, single-handed bounce, and 2-handed smooth drilling. A 60 frame-per-second high-definition video recorder was placed a standard distance from the model and used to calculate the depth of plunging. Analysis of variance with Fisher PLSD post hoc was used to compare techniques (significance P < 0.05). RESULTS The average ± SD plunge depths were 13.0 ± 4.2 mm (range 6.2-26.8 mm) for single-handed smooth, 17.2 ± 5.0 mm (range 8.0-28.8 mm) for single-handed bounce, and 10.6 ± 3.5 mm (range 5.8-19.2) for 2-handed smooth techniques. Difference among all 3 groups reached statistical significance. CONCLUSION Bounce technique had the greatest average depth and variance. The 2-handed technique demonstrated the least plunge and the lowest variance, indicating the highest degree of control. This study supports the use of a 2-handed technique for drilling when intraoperative circumstances permit.

Abstract
OBJECTIVE The objective of this study was to develop an assessment module for orthopaedic spine surgery residents which is cost-effective and can reliably test knowledge and surgical skills. DESIGN A ten-question multiple choice question and hands-on spine sawbones combination assessment was prospectively administered to consenting PGY-3 and PGY-4 residents before and after their 8-week spine rotation. Pre- and postrotation scores were compared using the paired t-test. SETTING The Department of Orthopaedics, The Ohio State University Wexner Medical Center, a large academic medical centre providing primary and tertiary care. PARTICIPANTS Orthopaedic resident physicians. RESULTS A total of 21 residents (15 PGY-3, 6 PGY-4) participated in the study. The mean pre- and postrotation written test score was 7.38 ± 1.53 and 9.24 ± 0.83, respectively (p < 0.001). Corresponding surgical skills assessment scores were 95.4% ± 4.7 and 97.1% ± 2.6, respectively (p = 0.10). Overall, the postrotation written and surgical scores improved and showed less variation about the mean. CONCLUSIONS This combination assessment measured improvement in below-average scoring residents and maintenance or improvement in residents with average and above average prerotation scores.

Abstract
OBJECTIVE To determine the effectiveness of simulator training on basic arthroscopic skills utilizing a novel, low-cost arthroscopic triangulation training system. DESIGN A randomized controlled trial of subjects without prior arthroscopy training was conducted, with participants randomized to receive either a fixed protocol of simulation training on a triangulation simulation model (30 minutes of training for 4 consecutive days), or no training. On Days 1 and 5, all participants were evaluated on 3 simulated arthroscopic tasks by an independent observer. Variables analyzed included how many times portals were changed, the time it took to complete the tasks, and the task completion rate. SETTING Arthrex Inc., Naples, FL. PARTICIPANTS Thirty-six participants (92% male, average 28 ± 5 years) with no prior arthroscopy training were randomized into 2 groups, with 17 in the training group (T) and 19 in the no-training group (NT). RESULTS On Day 1, there was no difference in rate of task completion between the T group and NT groups (41% versus 53%, p = 0.52). On Day 5, significantly more participants in the T group completed all tasks compared to the NT group (100% versus 63%, p = 0.008). Participants in the T group had significantly improved task completion times on Day 5 versus Day 1 (p < 0.05). Participants in the NT group had a significantly improved task completion time for Task 1 on Day 5 versus Day 1 (p = 0.037); no differences were found for Tasks 2 or 3. On Day 5, participants in the T group required significantly fewer portal changes compared to the NT group (2.35 ± 2.29 versus 6.95 ± 8.55, p = 0.039). CONCLUSIONS Simulation training on a simple, low-cost arthroscopic triangulation training system resulted in an overall improvement in arthroscopic probing and triangulation skills within 1 week of training, with significantly decreased task completion times and increased efficiency of movement.

Abstract
BACKGROUND General surgery residents interested in humanitarian careers may benefit from supplemental training beyond modern residency. The Colorado Humanitarian Surgical Skills Workshop is a 2-d cadaver-based course for senior surgical residents, teaching low-resource skills across multiple specialties, including orthopedics. We assessed the course's ability to transmit manual competence in a critical humanitarian surgical skill, powerless lower extremity external fixation. MATERIALS AND METHODS We created a novel standardized manual skills test of powerless lower extremity external fixation. Course participants had no prior experience with this technique. At course initiation, paired participants attempted to stabilize a proximal tibia-fibula fracture in a cadaver. Subsequently, participants received didactics from orthopedic surgeons followed by hands-on practice. At course completion, paired participants repeated the exercise. Fixator constructs were scored using standardized criteria. Precourse and postcourse surveys measured participants' level of confidence in performing external fixation. RESULTS Twelve senior surgical residents were included. Average scores of external fixator constructs improved significantly (23% pre versus 75% post, P < 0.01). On pretesting, none of the participants completed the exercise within 15 min. Only one of six constructs was marginally stable, and none were aligned. On post-testing, five of six teams completed the exercise in an average of 12.4 min. Four of six constructs were stable and two of six were also well aligned. Confidence with external fixation also improved significantly. CONCLUSIONS Participants in a short cadaver-based workshop demonstrated significant improvements in manual skill and confidence related to powerless external fixation. However, additional training is likely required to achieve clinical competence.

Abstract
OBJECTIVE Drilling through bone is a complex action that requires precise motor skills of an orthopedic surgeon. In order to minimize plunging and soft tissue damage, the surgeon must halt drill progression precisely following penetration of the far cortex. The purpose of this study was to create a low-cost and easy-to-use drilling simulator to train orthopedic residents in reducing the drill plunging depth. DESIGN, SETTING, PARTICIPANTS This prospective observational study was performed in the division of orthopedic surgery of a single tertiary medical center. The participants included 13 residents and 7 orthopedic specialists. The simulator consisted of a synthetic femur bone model and ordinary modeling clay, and the training unit consisted of a disposable plastic tube (∼US$14), clamps (∼US$58), and a power drill + drill bit (standard hospital equipment). Plunging depths were measured by the simulator and compared between orthopedic specialists, the 6 "senior residents" (3+ years) and the 7 "junior residents" during a training session. Measurements were taken again 2 weeks following the training session. RESULTS Initially, the plunging depths of the junior residents were significantly greater compared to those of the orthopedic specialists (7.00 mm vs. 5.28 mm, respectively, p < 0.038). There was no similarly significant difference between the senior residents and the orthopedic experts ([6.33 mm vs. 5.28 mm, respectively; p = 0.18). The senior residents achieved plunging depths of 5.17 mm at the end of the training session and 4.7 mm 2 weeks later compared to 7.14 mm at the end of the training session and 6 mm 2 weeks later for the junior residents. CONCLUSIONS This study demonstrated the capability of a low-cost drilling simulator as a training model for reducing the plunging depth during the drilling of bone and soft tissue among junior and senior residents.

Abstract
BACKGROUND Simulation-based education has been integrated into many orthopaedic residency programs to augment traditional teaching models. Here we describe the development and implementation of a combined didactic and simulation-based course for teaching medical students and interns how to properly perform a closed reduction and percutaneous pinning of a pediatric supracondylar humeral fracture. METHODS Subjects included in the study were either orthopaedic surgery interns or subinterns at our institution. Subjects all completed a combined didactic and simulation-based course on pediatric supracondylar humeral fractures. The first part of this course was an electronic (e)-learning module that the subjects could complete at home in approximately 40 minutes. The second part of the course was a 20-minute simulation-based skills learning session completed in the simulation center. Subject knowledge of closed reduction and percutaneous pinning of supracondylar humeral fractures was tested using a 30-question, multiple-choice, written test. Surgical skills were tested in the operating room or in a simulated operating room. Subject pre-intervention and post-intervention scores were compared to determine if and how much they had improved. RESULTS A total of 21 subjects were tested. These subjects significantly improved their scores on both the written, multiple-choice test and skills test after completing the combined didactic and simulation module. Prior to the module, intern and subintern multiple-choice test scores were significantly worse than postgraduate year (PGY)-2 to PGY-5 resident scores (p < 0.01); after completion of the module, there was no significant difference in the multiple-choice test scores. After completing the module, there was no significant difference in skills test scores between interns and PGY-2 to PGY-5 residents. Both tests were validated using the scores obtained from PGY-2 to PGY-5 residents. CONCLUSIONS Our combined didactic and simulation course significantly improved intern and subintern understanding of supracondylar humeral fractures and their ability to perform a closed reduction and percutaneous pinning of these fractures.
