Anatomical Relations

As its name suggests, the coracoclavicular ligament attaches the posterior ascent of the coracoid process of the scapula to the inferior surface of the clavicle, lateral to the subclavian groove.

Structure

The coracoclavicular ligament is composed of two parts, the trapezoid (lateral) and conoid (medial) parts, which are usually separated from each other by intervening fat or a bursa. The coracoclavicular ligament has been described as a fibrocartilaginous structure (Ockert et al., 2012).

Function

Although the coracoclavicular ligament is separate from the acromioclavicular joint, it is an important accessory ligament by helping maintain close apposition of the acromion to the clavicle. It also prevents excessive rotation of the clavicle and scapula.
