The Role of the Long Head of the Biceps Tendon in Posterior Shoulder Stabilization during Forward Flexion

Video Transcription

Video Summary

This summary is about a cadaveric study that aimed to assess the role of the long head of the biceps tendon in the stability of the shoulder joint during forward flexion. The study used 10 fresh frozen specimens and applied motion markers to track the movement of the humeral head. The researchers found that loading the biceps tendon resisted posterior translation of the humeral head, suggesting that the tendon plays a role in stabilizing the shoulder in forward flexion. These findings have implications for procedures that involve removing or unloading the biceps tendon, as it may contribute to instability and potentially lead to posterior glenoid wear or labral pathology. The study was funded by the RAF.
