Sternoclavicular joint
(Figures 12 and 13)
This is an atypical synovial joint, like the acromioclavicular joint, as the articular surfaces are covered with fibrocartilage. The medial end of the clavicle articulates with the manubrium and first costal cartilage. The capsule is thickened anteriorly and posteriorly to form the sternoclavicular ligaments. Further ligaments attach to the first rib and contralateral clavicle.
