Video Summary

The meeting discussed posterior shoulder instability, covering topics from basic repairs to arthroscopic bone block procedures. Dr. Owens began by addressing failure mechanisms and risk factors for posterior instability, emphasizing the prevalence of pain over obvious instability in young athletes. He cited key studies and provided insights into proper diagnostic procedures, including the use of contrast MRI for subtle posterior labral tears. Dr. Provencher followed by highlighting surgical techniques, particularly the importance of proper portal placement and knotless anchor fixation for consistent tension and reduced complications.<br /><br />Nick Trasalini, filling in for Dr. Waterman, discussed the unique challenges of managing posterior instability in throwers, emphasizing the need for protocols that differ from standard anterior instability repairs. He also talked about adaptations in throwers that can complicate the diagnosis, such as scapular dyskinesis.<br /><br />Dr. Dickens wrapped up the presentations by focusing on cases involving significant bone loss, often seen in revision surgeries or high-risk patients like those with seizure disorders. He discussed the pros and cons of different bone grafting materials and techniques, advocating for arthroscopic methods in many cases for better visualization and placement.<br /><br />The meeting concluded with a Q&A session where participants discussed the importance of individualized approaches and shared tips for optimizing both surgical and non-surgical treatments, particularly in complex cases. George Davies, a rehab expert, added that proper rehabilitation focusing on dynamic stability is crucial for the success of posterior instability treatments.
