AC joint injuries
Acromioclavicular joint (AC joint) dislocations are relatively common injuries, especially in athletes involved in contact sports or activities that place a high demand on the shoulder. The AC joint is located where the clavicle (collarbone) meets the acromion, which is part of the scapula (shoulder blade). Dislocations occur when there is a disruption or separation of the joint, typically due to a direct blow to the shoulder or a fall on an outstretched arm.
