The acromioclavicular (AC) joint is the articulation between the acromion process of the scapula and the lateral end of the clavicle. It is one of the important functional joints that allows a full range of movement at the glenohumeral joint. A joint capsule and several ligaments hold the joint in situ, assisted by the trapezoid and conoid coracoclavicular (CC) ligaments that connect the coracoid process of the scapula to the mid/lateral clavicle. The joint contains a fibrocartilaginous disc that cushions the articulations.
