Posterior sternoclavicular ligament
Posterior Sternoclavicular Ligament[edit | edit source]
The Posterior Sternoclavicular Ligament is a significant anatomical structure in the human body, specifically within the skeletal system. It is one of the key ligaments that contribute to the stability and function of the sternoclavicular joint.
Anatomy[edit | edit source]
The Posterior Sternoclavicular Ligament is located at the back of the sternoclavicular joint, connecting the clavicle to the sternum. It is a strong, fibrous band that is broader below than above. It is posterior to the articular disk and blends with the articular disk at the upper and lower margins.
Function[edit | edit source]
The primary function of the Posterior Sternoclavicular Ligament is to provide stability to the sternoclavicular joint. It prevents the medial displacement of the clavicle, thus ensuring the joint's stability during various movements of the shoulder girdle.
Clinical Significance[edit | edit source]
Injuries to the Posterior Sternoclavicular Ligament can lead to instability of the sternoclavicular joint, which can result in pain, limited range of motion, and potential complications such as sternoclavicular joint dislocation.
