costoclavicular ligament

The inferior surface has an oval impression at its medial end for the costoclavicular ligament.

The costoclavicular ligament is the main limitation to movement, therefore, the main stabilizer of the joint.

It arises by a short, thick tendon from the first rib and its cartilage at their junction, in front of the costoclavicular ligament.

On the medial part of the clavicle is a broad rough surface, the costal tuberosity (impression for costoclavicular ligament), rather more than 2 cm.

The costoclavicular ligament (rhomboid ligament), is the anatomical name of a ligament that is short, flat, strong, and rhomboid in form.

The anterior surface is convex, and looks forward and upward: that of the first gives attachment to the costoclavicular ligament and the subclavius muscle; those of the first six or seven at their sternal ends, to the pectoralis major.
