Interclavicular Ligament

The Interclavicular Ligament is a thin, fibrous band that connects the sternal ends of the clavicles, forming part of the sternoclavicular joint. This joint is the articulation between the clavicle and the sternum, providing stability and facilitating movements of the shoulder girdle. Located at the superior aspect of the sternum, the interclavicular ligament spans the gap between the two clavicles, reinforcing the joint capsule. It contributes to the overall structural integrity of the sternoclavicular joint, which is one of the main connections between the axial and appendicular skeletons. While the interclavicular ligament is not as prominent as some other ligaments in the shoulder region, it plays a supportive role in maintaining proper alignment and function of the clavicles. It helps prevent excessive upward or downward displacement of the clavicles during movements of the shoulder and arms. Trauma, dislocations, or degenerative changes in the sternoclavicular joint can affect the interclavicular ligament, potentially leading to instability or dysfunction. Understanding the anatomy and function of this ligament is crucial in diagnosing and managing conditions affecting the sternoclavicular joint.
