AANA Shoulder Arthroscopy - August 2024-ACJ_ Solutions, Case Based Acute and Chronic Cases

Video Transcription

Video Summary

Dr. Gus Mazak from the University of Connecticut discusses acromioclavicular (AC) joint injuries and their treatment, emphasizing the importance of the acromioclavicular ligament complex (ACLC) in stabilizing horizontal and posterior rotation. He reviews anatomy, biomechanics, and clinical approaches, noting that both operative and non-operative treatments yield good outcomes and decisions depend on individual factors like injury grade, sport, and symptoms. Acute injuries (<3 weeks) often benefit from arthroscopic procedures promoting natural healing, while chronic injuries may require open ligament reconstruction with grafts and cortical buttons for stability. He highlights surgical techniques including careful drilling to avoid coracoid fractures, meticulous ligament reconstruction to prevent posterior rotation, and secure deltoid and trapezius closure. Postoperative care involves bracing to unload the joint. He concludes that coracoclavicular reconstructions alone don't restore full stability, making ACLC repair or reconstruction critical for optimal functional recovery.
