Anatomy, Shoulder and Upper Limb, Coracoclavicular Joint (Coracoclavicular Ligament)

Excerpt

The coracoclavicular ligament (CCL) serves as the acromioclavicular ligament's primary support (see Image. Left Shoulder Anatomy). These 2 ligaments coordinate to stabilize the acromioclavicular joint (ACJ), a major shoulder joint. The ACJ is a synovial plane joint that helps stabilize the shoulder girdle. This joint's primary support derives from the acromioclavicular ligament intrinsic to the joint and the CCL extrinsic to the articulation. The CCL does not directly cross the ACJ. However, the CCL helps maintain the proper anatomical relationship of the acromion to the clavicle.

CCL injuries are commonly associated with shoulder separations, particularly in high-impact sports or trauma. Surgical intervention may be necessary for severe CCL injuries. Understanding the anatomy and function of this ligament is essential for managing various conditions affecting the shoulder.
