Case-based Approach to the Management of AC Joint Injuries – An International Perspective (2021 Annual Meeting)-Case-based Approach to the Management of AC Joint Injuries

Case-based Approach to the Management of AC Joint Injuries - An International Perspective-Mulcahey

Video Transcription

Video Summary

The video provides an overview of AC joint injuries, including anatomy, mechanism of injury, classification, diagnosis, and management. The transcript presents a case study of a 59-year-old male who fell and injured his left shoulder, which resulted in a type 2 AC separation. Initially, the patient received a steroid injection and underwent physical therapy. After two weeks, an MRI showed a tear of the AC ligaments but intact CC ligaments and rotator cuff. Non-operative management was continued. Two years later, the patient returned with left shoulder pain, which was unrelated to the AC joint. The video then discusses the anatomy of the AC joint, including the AC and CC ligaments, and their role in stabilizing the joint. It also mentions a study that evaluated the biomechanics of the AC joint capsules. The Rockwood classification system for AC joint injuries is explained, ranging from type 1 (sprain) to type 6 (rare). Associated shoulder pathologies and the mechanism of injury are discussed. Diagnostic tests and imaging, such as x-rays, ZENKA view, and MRI, are mentioned. Management options, including non-operative and operative treatment, are reviewed. The presence of scapular dyskinesia in AC joint injuries is discussed, as well as the potential development of Sixth Scapula Syndrome. The video concludes by summarizing that the AC joint is crucial for arm movement, and treatment depends on the severity of the injury.
