Interclavicular Ligament[edit]

Diagram of the interclavicular ligament (highlighted in red) connecting the clavicles across the sternum.

The interclavicular ligament is a significant structure in the human anatomy of the shoulder girdle. It is a part of the sternoclavicular joint, which is the articulation between the clavicle and the sternum. This ligament plays a crucial role in stabilizing the clavicles and maintaining the integrity of the shoulder girdle.

Anatomy[edit]

The interclavicular ligament is a broad, flat band of fibrous tissue that extends across the superior aspect of the manubrium of the sternum. It connects the sternal ends of the left and right clavicles, forming a bridge over the jugular notch. This ligament is continuous with the capsule of the sternoclavicular joint and is reinforced by the sternocleidomastoid muscle fibers.

Function[edit]

The primary function of the interclavicular ligament is to provide stability to the sternoclavicular joint. It limits excessive depression of the clavicle, which can occur during movements such as shoulder abduction and elevation. By doing so, it helps prevent dislocation of the clavicle from the sternum.

Clinical Significance[edit]

Injuries to the interclavicular ligament are rare but can occur due to trauma or excessive force applied to the shoulder girdle. Such injuries may lead to sternoclavicular joint dislocation or instability. Treatment typically involves rest, immobilization, and in severe cases, surgical intervention.

Related Structures[edit]

The interclavicular ligament is closely associated with other structures of the sternoclavicular joint, including:

These ligaments work together to maintain the stability and function of the sternoclavicular joint.

This ligament plays a crucial role in stabilizing the clavicles and maintaining the integrity of the shoulder girdle.
-The term "Interclavicular" is derived from the Latin words "inter" meaning between, and "clavicula" meaning little key, referring to the shape of the clavicle.
-==Anatomy==
+=== Anatomy ===
-The Interclavicular ligament is a strong fibrous band that extends from the sternal end of one clavicle to that of the other, passing over the [[sternum]]. It is broader in the middle than at the ends, and intimately blended with the [[sternoclavicular joint]] capsule.

-The primary function of the Interclavicular ligament is to prevent excessive lateral and superior displacement of the clavicle, thereby maintaining the stability of the sternoclavicular joint. It also helps in transmitting the weight of the upper limb to the axial skeleton.
-==Clinical significance==
+=== Function ===
-Injury to the Interclavicular ligament can lead to sternoclavicular joint dislocation. This can result in pain, swelling, and limited movement of the shoulder. Treatment usually involves rest, ice, compression, and elevation (RICE), along with physical therapy.
