Abstract
Acromioclavicular (AC) joint disruptions are frequent reasons for posttraumatic shoulder dysfunction, particularly among young and active patients. The AC joint, along with its dynamic and static stabilizers (coracoclavicular ligaments, acromioclavicular capsule, and ligaments), is a major contributor to physiological kinematics of the shoulder, permitting controlled rotation of the clavicle against the acromion during movement of the arm. Therefore, diagnosis and consecutive treatment of injuries affecting structural integrity, and thereof joint function, are essential. Besides the patient’s history, clinical assessment of vertical or horizontal instabilities and pain about the anterior or posterior aspect of the AC joint may suggest acute or chronic injury. Bilateral nonweightbearing panoramic and Alexander views remain a key radiographic imaging modality both for the diagnosis and for classification of the injury. The Rockwood classification, which is based on the severity of the injury, can help practitioners in finding adequate treatment options.
