The conoid ligament is one of two components forming the coracoclavicular (CC) ligament. The trapezoid ligament is the other component.

Gross anatomy

The conoid ligament takes the shape of an inverted cone. It is the posteromedial part of the coracoclavicular ligament. Its apex originates from the knuckle of the coracoid process on the scapula. It has a wide attachment around the conoid tubercle on the inferior surface of the clavicle.

Radiographic features

The integrity of the CC ligaments are assessed on plain radiographs by the coracoclavicular distance.
