Costoclavicular ligament
The costoclavicular ligament, also known as the rhomboid ligament or Halsted's ligament, is a ligament of the shoulder girdle. It is short, flat, and rhomboid in form. It is the major stabilizing factor of the sternoclavicular joint and is the axis of movement of the joint, especially during elevation of the clavicle.[1]
