2021 Annual Meeting Shoulder Access Pass-Failure of Posterior Capsulolabral Repair is Correlated with Percent of Glenoid Bone Loss

Failure of Posterior Capsulolabral Repair is Correlated with Percent of Glenoid Bone Loss

Video Transcription

Video Summary

In this video, the speaker presents their research on posterior shoulder instability and the factors contributing to surgical failure rates. They mention previous studies that have found that cumulative microtrauma and a flexed internally rotated position are common causes of posterior instability. The speaker discusses various risk factors for developing posterior instability, including increased retroversion and decreased glenoid bone width. They also highlight the differences in bony morphology between anterior and posterior instability. The purpose of their study was to evaluate advanced MRI measures in patients who underwent posterior shoulder capsular labral repair, focusing on glenoid bone width and bone loss. They found that patients with narrow glenoid bone width and higher percentages of bone loss had higher failure rates. The speaker emphasizes the importance of accurately measuring and correcting imaging images and concludes by acknowledging the generally positive outcomes of arthroscopic posterior capsular labral repair.
