Video Summary

The talk reviews the anatomy and function of the biceps-labral complex in the shoulder, emphasizing their role in stability. The labrum deepens the glenoid socket, provides stability, and protects cartilage. The biceps tendon originates near the labrum and shows complex interactions but its exact role—whether in humeral head compression, stabilization, or depression—is unclear. Studies show conflicting evidence: biomechanical data suggest the biceps reduces glenohumeral translation, while EMG data indicate limited role during throwing. SLAP tears destabilize the shoulder and increase strain on the labrum, especially with an intact biceps tendon. Overall, the biceps-labrum interplay is complex and requires further research.
