Closing-wedge Osteotomies: Can We Do and Teach Better?

BACKGROUND: Wedge osteotomies are ubiquitous in pediatric orthopaedics and limb deformity surgery; however, there is no universally preferred methodology for these procedures. This study aims to determine the relative accuracy and effectiveness of several measuring and marking methods to guide best practices for wedge-shaped osteotomies in long bones. METHODS: An observational cohort study was completed. Orthopaedic residents (postgraduate years 1 to 5) completed 30-degree wedge osteotomies on a sawbone (Pacific Research Lab) femur utilizing a standard oscillating saw under 3 measuring conditions: (1) no measurement tool, (2) 30-degree triangle, and (3) goniometer, in combination with 2 different marking methods: (1) marking pen or (2) pin placement. Demographic characteristics and osteotomy performance (quality, completion time, and accuracy) were assessed. Quality was ranked as perfect (1), mild step-off (2), or gross surface irregularity (3). Multivariate regressions and analysis of variance were performed comparing demographics, osteotomy performance, and measuring methods. RESULTS: Twenty-four residents were included for analysis; 6 were female (25%). Female sex was independently associated with longer completion time when evaluating all combined scenarios (138 vs. 99 s, P =0.003) without differences in surface quality or angle accuracy. There were no significant associations between measuring technique and accuracy or surface quality, but use of the goniometer and the triangle both were associated with significantly longer completion time compared with no visual aid ( P =0.002 and 0.007). When controlling for measuring technique, use of the pen as a marking technique had significantly shorter completion times ( P <0.001), higher surface quality ( P <0.001), and better accuracy ( P <0.001) than guide pins. CONCLUSIONS: We recommend the use of a marking pen in combination with the surgeon's preferred measuring guide to optimize trainees' performance of closing wedge osteotomies. Future research is necessary to corroborate these findings in a higher fidelity setting, such as a cadaveric study. Further, while male residents complete wedge osteotomies quicker than female residents, quality and accuracy are comparable among trainees. Slower pace should not be conflated with poor performance but rather should inform effective intraoperative teaching for diverse trainees.

Excess non-COVID-19-related mortality among inflammatory bowel disease decedents during the COVID-19 pandemic.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic disrupted healthcare in the United States. AIM: To investigate COVID-19-related and non-COVID-19-related death and characteristics associated with excess death among inflammatory bowel disease (IBD) decedents. METHODS: We performed a register-based study using data from the National Vital Statistics System, which reports death data from over 99% of the United States population, from January 1, 2006 through December 31, 2021. IBD-related deaths among adults 25 years and older were stratified by age, sex, race/ethnicity, place of death, and primary cause of death. Predicted and actual age-standardized mortality rates (ASMRs) per 100000 persons were compared. RESULTS: 49782 IBD-related deaths occurred during the study period. Non-COVID-19-related deaths increased by 13.14% in 2020 and 18.12% in 2021 [2020 ASMR: 1.55 actual vs 1.37 predicted, 95% confidence interval (CI): 1.26-1.49; 2021 ASMR: 1.63 actual vs 1.38 predicted, 95%CI: 1.26-1.49]. In 2020, non-COVID-19-related mortality increased by 17.65% in ulcerative colitis (UC) patients between the ages of 25 and 65 and 36.36% in non-Hispanic black (NHB) Crohn's disease (CD) patients. During the pandemic, deaths at home or on arrival and at medical facilities as well as deaths due to neoplasms also increased. CONCLUSION: IBD patients suffered excess non-COVID-19-related death during the pandemic. Excess death was associated with younger age among UC patients, and with NHB race among CD patients. Increased death at home or on arrival and due to neoplasms suggests that delayed presentation and difficulty accessing healthcare may have led to increased IBD mortality.
