2022 AOSSM Annual Meeting Recordings with CME-The Role of the Long Head of the Biceps Tendon in Posterior Shoulder Stabilization during Forward Flexion

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

Video Transcription

Video Summary

The video discusses a lack of long-term outcome studies on long head of the biceps tendon procedures and their effect on glenohumeral kinematics. The study aims to assess the role of the biceps tendon on humeral head translation during forward flexion. Using cadaveric specimens, the study found that loading the biceps tendon resisted posterior translation of the humeral head, indicating its role as a posterior stabilizer. Unloading the biceps tendon, as done in tenodesis procedures, may contribute to micro-instability and shift the contact point posteriorly. Further research is needed to determine the clinical implications of these findings. The study was funded by the RAF.
