Background: Medical students and residents rely increasingly on web-based education. Online videos provide unique
opportunities to share knowledge. The objective of this study was to investigate the accuracy and quality of instructional
videos on the physical examination of the elbow and identify factors influencing educational usefulness.
Methods: On October 7, 2018, a search on YouTube, VuMedi, Orthobullets, and G9MD was performed. Videos were
rated for accuracy and quality by two independent authors using a modified version of a validated scoring system for
the nervous and cardiopulmonary system. Inter-rater reliability was analysed.
Results: The 126 included videos were uploaded between June 2007 and February 2018. Twenty-three videos were
indicated as useful for educational purposes. Accuracy, quality and overall scores were significantly higher for videos
from specialized platforms (VuMedi, Orthobullets, G6MD) compared to YouTube. Video accuracy and quality varied
widely and were not correlated. Number of days online, views, and likes showed no or weak correlation with accuracy
and quality. For the overall score, our assessment tool showed excellent inter-rater reliability.
Conclusion: There is considerable variation in accuracy and quality of currently available online videos on the physical
examination of the elbow. We identified 23 educationally useful videos and provided an assessment method for the
quality of educational videos. In educational settings, this method may help students to assess video reliability and aid
educators in the development of high-quality instructional online content.
