Structure
The costoclavicular ligament is a short, but powerful cone-shaped ligament that connects the inferior margin of the sternal end of the clavicle to the superior margin of the first rib and its associated costal cartilage. The clavicle is marked by a roughened, depressed area on its medial side to which the costoclavicular ligament attaches.
Function
The costoclavicular ligament acts to stabilize the sternoclavicular joint.
