RESUMEN
OBJECTIVE: To measure surgeon engagement and preferred video duration in a video-based learning program for nerve surgery. BACKGROUND: Educational videos can improve, standardize, and democratize best practices in surgery. To improve care internationally, educators must optimize their videos for learning. However, surgeon engagement and optimal video duration remain undefined. METHODS: A YouTube channel and a video-based learning website, PASSIO Education (passioeducation.com), were examined from 2011 to 2017. We assessed views, geographic location, audience engagement (average percent of video watched), audience retention (percent of viewers at each timepoint), and usage of short (median 7.4, range 4.1-20.3 min) and long (median 17.2, range 6.1-47.7 min) video formats for the same procedures. A survey of PASSIO Education membership examined preferred video duration. RESULTS: Our 117 nerve surgery videos attained over 3 million views with 69% originating outside of the United States. While YouTube achieved more international exposure, PASSIO Education attained a greater mean engagement of 48.4% (14.3% absolute increase, P < 0.0001). Surveyed surgeons (n = 304) preferred longer videos when preparing for infrequent or difficult cases compared with routine cases (P < 0.0001). Engagement declined with video duration, but audience retention between short and long video formats was correlated (τB = 0.52, P < 0.0001). CONCLUSIONS: For effective spread of best practices, we propose the joint use of YouTube for audience outreach and a surgeon-focused platform to maximize educational value. Optimal video duration is surgeon- and case-dependent and can be addressed through offering multiple video durations and interactive viewing options.

Thumb duplication is a congenital hand difference that occurs in 0.08 of every 1000 live births and is categorized by level of duplication by the Wassel classification system. The anatomy and reconstruction of type VI thumb duplication is not well described, likely due to its rarity. In this report, we detail the anatomy and reconstruction of an ulnar-dominant Wassel VI thumb duplication, with particular attention paid to management of the first CMC joint and intrinsic muscle rebalancing of the preserved digit.
RESUMEN
BACKGROUND: Surgical videos are increasingly common, although their role in residency curricula remains unclear. The aim of this study was to evaluate the impact of an educational surgical video on resident performance of an open carpal tunnel release through an Objective Structured Assessment of Technical Skills and serial questionnaires. METHODS: Twenty-two residents representing six postgraduate years were randomized to receive text-based materials with or without a surgical video before performing a carpal tunnel release on human cadavers. Procedures were video recorded, anonymized, and independently evaluated by three hand surgeons using the Objective Structured Assessment of Technical Skills global rating scale, a procedure-specific technical rating scale, a record of operative errors, and pass/fail designation. Residents completed questionnaires before and after the procedure to track confidence in their technical skills. RESULTS: Residents in their first and second postgraduate years (n = 10) who watched the surgical video committed fewer operative errors (median, 4 versus 1.3; p = 0.043) and were more confident in their abilities following the procedure (median, 75 versus 32; p = 0.043) than those receiving text resources alone. There were no significant differences in Objective Structured Assessment of Technical Skills performance or questionnaire responses among more senior residents (n = 12). The technical rating scale was internally consistent (Cronbach α = 0.95; 95 percent CI, 0.91 to 0.98), reliable (intraclass correlation coefficient, 0.73; 95 percent CI, 0.40 to 0.88), and correlated with surgical experience (Spearman ρ = 0.57; p = 0.006). CONCLUSION: Watching an educational surgical video to prepare for a cadaveric procedure significantly reduced operative errors and improved confidence among junior trainees performing a carpal tunnel release.
