Body was changed:

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

Gross anatomy

The trapezoid ligament is a broad quadrilateral ligament that is quite thin. Its positioned almost horizontally. It is the anterolateral part of the CC ligament. The trapezoid ligament arises from the upper surface of the coracoid process. It attaches to the trapezoid line (or ridge) on the inferior surface of the clavicle

The anterior border of the trapezoid ligament is free. The posterior border attaches to the conoid ligament. 

Radiographic features

The coracoclavicular distance is used to assess CC ligament integrity on plain radiographs.
