Sternoclavicular ligament

Sternoclavicular Ligament

The sternoclavicular ligament is a significant anatomical structure in the human body, specifically within the skeletal system. It is one of the many ligaments that contribute to the stability and mobility of the body's joints.

Anatomy

The sternoclavicular ligament is a strong, fibrous band that connects the sternum (breastbone) to the clavicle (collarbone). It is divided into two parts: the anterior and posterior sternoclavicular ligaments. These ligaments serve to stabilize the sternoclavicular joint, which is the only joint that connects the arm to the rest of the skeleton.

Function

The primary function of the sternoclavicular ligament is to provide stability to the sternoclavicular joint. This joint is responsible for the majority of the shoulder's movement, and the ligament helps to prevent dislocation. Additionally, the sternoclavicular ligament aids in transmitting the force from the upper limb to the axial skeleton.

Clinical Significance

Injuries to the sternoclavicular ligament can occur due to trauma, such as a direct blow to the chest or shoulder. This can result in a sternoclavicular joint dislocation, which can cause pain, swelling, and limited movement. Treatment for such injuries typically involves rest, physical therapy, and in severe cases, surgery.
