2022 AOSSM Annual Meeting Recordings with CME-Biomechanical Evaluation of Posterior Shoulder Instability with a Clinically Relevant Posterior Bone Loss Model

Biomechanical Evaluation of Posterior Shoulder Instability with a Clinically Relevant Posterior Bone Loss Model

Video Transcription

Video Summary

The video discusses the characterization and biomechanical effectiveness of a posterior labral repair in the presence of posterior glenoid bone loss. Posterior glenoid bone loss is different from anterior glenoid bone loss and is caused by repetitive activities that load the shoulder in a forward flexed and internally rotated position. The study used cadaveric shoulders to evaluate the effectiveness of a posterior labral repair in different bone loss states. The results showed that labral repair alone significantly increased stability, but larger bone loss states may require bony augmentation for adequate stability. These findings can help guide clinical decision-making for patients with posterior shoulder instability.
