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

Video Transcription

Video Summary

The video is a presentation of research on posterior glenoid bone loss and its impact on shoulder stability. The study used cadaveric shoulders to evaluate the effectiveness of posterior labral repair in different bone loss models. The results showed that labral repair alone significantly increased stability, but larger bone loss states may require bony augmentation for adequate stability. The study had limitations, such as not accounting for rotator cuff activation and glenoid version. In conclusion, labral repair can improve stability in cases of small bone loss, but larger bone loss may require additional measures. No specific credits were mentioned in the transcript.
