2022 AOSSM Annual Meeting Recordings with CME-The Natural History of Nonoperative Treatment of Posterior Instability in a High Demand Population

The Natural History of Nonoperative Treatment of Posterior Instability in a High Demand Population

Video Transcription

Video Summary

The video discusses the rate of failure in nonoperative treatment of posterior shoulder instability in a young and active population. The study involved 123 active duty service members with a minimum of two-year follow-up. Nonoperative treatment criteria included activity modification, physical therapy, and gradual return to play. The failure rate of nonoperative treatment was found to be 47%, with risk factors including greater posterior acromial height, greater posterior humeral head subluxation ratio, and posterior glenoid bone loss. Serial MRI showed that posterior glenoid bone loss increased from 2.7% to 6.5% after nonoperative treatment failure. This study adds to existing research on acromial morphology and glenoid bone loss in relation to shoulder instability. The video also mentions that Dr. Walts will discuss a biomechanical evaluation of posterior shoulder instability and a clinically relevant posterior bone loss model.
