Structure

As its name suggests, the conoid ligament is triangular or cone-shaped and forms the medial part of the coracoclavicular ligament. It has a broad base that attaches to the conoid tubercle of the clavicle, and narrower apex, which attaches to the upper surface of the coracoid process of the scapula, lateral to the scapular notch.

It has a free anterior border, while its posterior border is joined with the coronoid ligament.

Function

As a rule, triangular or cone-shaped ligaments keep structures in close apposition, and therefore, the conoid ligament keeps the coracoid process of the scapula and the clavicle in close apposition.

Coracoid Process

ScienceDirect image

As with all coracoid process fractures managed surgically, an anterior deltoid-splitting or a limited deltopectoral approach may be used, and the rotator interval is opened as needed for optimal exposure of the fracture site (Fig. 7-50).
