Video Transcription

Video Summary

Dr. Morgan discusses a case of a semi-pro left-hander with a biceps tendon avulsion, noting he repaired the interval lesion allowing pain-free throwing. Dr. Kibler references Greg Bain’s work on the biceps acting as a tension band across the posterior labrum, crucial during maximum external rotation and forward flexion. This tension band helps maintain glenohumeral joint stability. Damage to this mechanism can cause symptoms in throwing athletes, linked to posterior labral pathology. Dr. Kibler plans to elaborate on this concept in an upcoming talk, highlighting its relevance to shoulder injuries in athletes.
