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 conoid ligament spans the “elbow” of the coracoid process to the posterior border of the inferior aspect of the clavicle known as the conoid tubercle¹.

The conoid lig. is deep/posterior to the trapezoid ligament’s attachment on the conoid tubercle¹.
