Ligamentum coracoclaviculare

The coracoclavicular (CC) ligament is the major vertical stabilizing factor of the acromioclavicular joint.

Gross anatomy

The coracoclavicular ligament can be divided into two parts, the more medial conoid ligament and trapezoid ligament.

  • conoid ligament
  • trapezoid ligament
    • origin: trapezoid ridge on the coracoid process of the scapula
    • runs laterally and horizontally, attaching to the underside of the clavicle (to the similarly named, trapezoid ridge)

Radiographic features

The integrity of the CC ligament is inferred on plain radiographs by the coracoclavicular distance.
