The acromioclavicular joint (ACJ) is formed by the junction between the acromion process of the scapula and the distal clavicle. It is a plane synovial joint and forms part of the shoulder girdle (ACJ, GHJ, and SCJ). It can include a fibrocartilaginous disk

Range of Motion

There is significant motion at the ACJ during elevation of the humerus.(See Shoulder Biomechanics).[1]
