2024 AOSSM Annual Meeting Recordings-Concurrent Session B: Shoulder Potpourri

Video Transcription

Video Summary

In this Shoulder Potpourri session, various experts discussed techniques and research related to shoulder injuries and treatments. Scott Feely from Walter Reed presented his study on the overreduction of type 5 AC joint dislocations. His research indicated that overreduction during acute fixation can decrease the rate of loss of reduction post-operatively. Feely's study, which examined data from 2013 to 2020, revealed that overreduction is protective and suggested re-evaluating the traditional definition of radiographic loss of reduction.<br /><br />Patrick Morris from Brown discussed a cadaveric biomechanical study focused on remplissage techniques for shoulder instability. His findings showed that two fixation points, whether medial or central, provided more stability than a single point. Despite this stability, Morris recommended that one anchor might suffice to restore native stability.<br /><br />Fabian Su from UCSF evaluated whether MR arthrography offers improved diagnostic accuracy for labral, osseous, and chondral lesions in patients with posterior shoulder instability compared to conventional MRI. His study concluded that both imaging modalities had similar diagnostic accuracies, but MR arthrography incurs higher costs and involves more invasive procedures without added diagnostic benefit.<br /><br />In addition to these presentations, several experts demonstrated their surgical techniques. Julie Bishop highlighted the importance of precise portal placement, meticulous preparation of the labrum, and coordination during surgery. Lyle Cain emphasized the use of all suture knotless anchors, sequential and balanced capsular repairs, and intraoperative suture management.<br /><br />Brian Waterman discussed the surgical management of AC joint injuries, underscoring the need to address associated pathology comprehensively and advocating for a combination of biologic and synthetic materials to ensure better outcomes.<br /><br />The session concluded with case discussions, allowing experts to share insights and strategies for managing complex shoulder injuries, particularly in athletes.
