Trapezoid ligament
Coracoclavicular ligament
Medial coracoclavicular, Conoid, and trapezoid ligaments are the 3 coracoclavicular ligaments1.
The conoid ligament and the trapezoid ligament are 2 extra-articular ligaments that help to stabilize the acromioclavicular joint1.
The trapezoid lig. attaches to the coracoid process, but is superficial/anterior to the conoid ligament1. The trapezoid lig. runs superolaterally to insert on the clavicle, anterolaterally to the conoid tubercle1.
Function
The trapezoid lig functions to limit the closing angle between the clavicle and scapula1.
