The Coronavirus Disease 2019 (COVID-19) pandemic presented a novel challenge to modern healthcare systems and medical training. Resource allocation and risk mitigation dramatically affected resident training. The objective of this article is to develop new strategies to maintain a healthy, competent residency program while combating the unique challenges to resident education and wellness. In 2020, our institution implemented a revolving 3-Team system. While the "Inpatient-Team" delivered direct care, the "Back-up Team" and "Quarantine-Team" managed the telemedicine virtual clinic and education-wellness strategy, respectively. Our 3-Team system allowed delivery of safe, high-quality patient care while optimizing resident education, research, and wellness. The efficient use of technology led to both improved virtual education outside of the hospital and intentional wellness opportunities despite social distancing restrictions. Utilization of virtual platforms for patient care, education, research, and wellness grew out of necessity in this pandemic, yet represent an opportunity for lasting improvement.

The purpose of this study was to analyze the demographics and backgrounds of U.S. orthopaedic surgery residency program directors (PDs). We collected publicly available information on 189 orthopaedic surgery residency PDs. Of those PDs, 90% were male MDs with an average age of 52. The average age at PD appointment was 45. The average duration of appointment was 7 years. About 81% of programs were university-affiliated, and 61% were in an urban environment. PDs attended 100 medical schools, 129 residencies, and 96 fellowships. of PDs, 87% completed fellowships, commonly in trauma and sports medicine. There was no significant difference between male and female PDs when comparing age, academic appointment, or urban/rural environment. Most female PDs (89%) were at university-based hospitals. Of PDs at osteopathic-focused programs, 28% had an MD/PD. No program with an allopathic focus had a DO/PD. Lastly, 38% of PDs worked at the center where they completed residency.

The purpose of this study is to investigate the association between Hirsch index (h-index) and academic rank among foot and ankle surgeons affiliated with American Orthopaedic Foot and Ankle Society (AOFAS) fellowship programs. The total number of publications, academic rank, years in practice, fellowship training pedigree, and h-indices of 176 foot and ankle surgeons from 48 AOFAS fellowship programs were recorded, and statistical analysis was performed. We found a strong association between total number of publications and h-index. Number of publications, h-index and training program affiliation were associated with higher academic rank, except at the chair/director position. Overall, h-index is a stronger predictor of academic rank than number of publications. The results of this study suggest that h-index and total number of publications are associated with a higher academic rank for full-time foot and ankle fellowship affiliated surgeons.

This study's objective was to identify a difference in maximum temperature change during forward versus oscillating drilling of cadaveric bone. Paired femurs were dissected from the soft tissue of five cadavers. Each cadaver had one femur assigned to forward and the other to oscillation. The first drill hole was 2.5 cm distal to the lesser trochanter and the remaining 10 holes were evenly spaced 2 cm apart. A System 7 drill and 3.5 mm drill bit were attached to an Instron 5500R to provide a progressive force of 50 Newtons per minute for each drill hole. A thermal camera recorded each drilling. A new drill bit was used for each femur. Fifty bicortical drillings were analyzed in each group. The average time to complete forward drilling (45.0 seconds) was shorter compared to oscillation (55.5 s, p < 0.001). The average force required for forward drilling (27.7 N) was lower than for oscillation (44.3N, p < 0.001). The maximum change in temperature during the drilling process was similar (oscillating 100.2° F vs. forward 100.7° F, p = 0.871). The maximum change in temperature at the near cortex was lower for oscillation (78.1°F) compared to forward drilling (89.1°F, p = 0.011), while the maximum change at the far cortex was lower for forward drilling (89.3°F) compared to oscillation (95.8°F, p = 0.115) but not significantly. Overall, there is no difference in the thermal output between techniques. Oscillation may be beneficial in proximity to vital structures or to navigate narrow bony corridors, but it requires additional time and force.

This study aimed to determine intra-observer and inter-observer reliability of the Mayo Elbow Performance Score (MEPS). Patients undergoing elbow surgery completed a MEPS questionnaire initially and another 2-3 weeks later. During the second interview, patients completed the Oxford Elbow Score (OES) for comparison. Intraclass correlation coefficients (ICC) and Pearson correlation coefficients (PCC) > 0.80 indicated substantial agreement. In 42 patients who had elbow surgery, the average MEPS score initially was 78 (range, 5-100, SD 22.4) and 77 (range, 5-100, SD 21.5) at second interview. The average normalized OES score was 79 (range, 17-100, SD 23.6). The ICC for MEPS scores at the two time points was 0.90, and the PCC between the MEPS and OES scores was 0.87, indicating substantial agreement. The MEPS has strong intra-observer reliability at different time points and strong inter-observer reliability when compared with the OES, validating the MEPS as an outcome measure of elbow surgery.
