2023 Specialty Day Access Pass-Posterior Labral Repair

Video Transcription

Video Summary

Dr. Sheehan discusses posterior labral tears, emphasizing the complexity of shoulder instability involving both anterior and posterior structures. He highlights differing injury mechanisms: axial posterior force common in linemen and torsional injuries in throwers. Diagnosis combines history, physical exams (e.g., posterior load shift test), and advanced imaging revealing labral tears and bone loss. Surgical technique is crucial—lateral decubitus positioning, precise portal placement, inferior-to-superior capsular shift, and closing the posterior portal improve outcomes. Non-operative treatment suits many, but throwers face more challenges returning to prior performance. Overall, tailored approaches and meticulous technique yield excellent results in managing posterior instability.
