Background: This study seeks to examine the reliability, quality, and content of YouTube videos on cubital tunnel syndrome, on which there is presently a paucity of information.
Methods: The top 50 unique YouTube videos by relevance resulting from the Boolean search term "cubital tunnel + cubital tunnel syndrome" were identified, with video properties for analysis including source, upload date, duration, views, and comments. Content was assessed using the Journal of American Medical Association (JAMA) criteria, the Global Quality Score (GQS), and a "Cubital Tunnel-Specific Score" (CTSS).
Results: The average video saw 72 108 ± 199 362 views, with videos produced by allied (nonphysician) health professionals demonstrating the highest mean views (111 789 ± 294 471 views). Videos demonstrated low mean JAMA scores (2.4/4 ± 0.7), GQS (2.8/5 ± 1.3), and CTSS (7.5/21 ± 4.3), with academic and nonacademic physician videos demonstrating significantly greater mean GQS and CTSS scores when compared with videos by allied health professionals. Positive independent predictors for GQS included academic sources (β = 1.871), nonacademic physician sources (β = 1.651), and video duration (β = 0.102), which were likewise positive predictors for CTSS (β = 4.553, 4.639, 0.374). Content relating to surgical techniques or approaches for cubital tunnel decompression had the greatest CTSS scores (11.2 [4.2]).
Conclusions: YouTube is a source of highly accessible information on cubital tunnel syndrome, although the average video presents generally poor and inadequate information. Directing patients toward higher quality video resources can be a meaningful component of patient education.
