Subscapular aponeurosis

Subscapular aponeurosis is a fibrous membrane that covers the subscapularis muscle. It is a part of the human anatomy and plays a crucial role in the functioning of the shoulder joint.

Structure

The subscapular aponeurosis is a thin, flat, and broad membrane that covers the anterior surface of the subscapularis muscle. It is attached to the scapula at the subscapular fossa and extends to the humerus, providing a smooth surface for the movement of the shoulder joint.

Function

The primary function of the subscapular aponeurosis is to protect the subscapularis muscle and provide a smooth surface for the movement of the shoulder joint. It also plays a role in the stabilization of the shoulder joint and assists in the movement of the arm.

Clinical significance

Injuries or disorders of the subscapular aponeurosis can lead to shoulder pain and limited range of motion. Conditions such as subscapularis tendonitis and rotator cuff tear can involve the subscapular aponeurosis. Treatment options include physical therapy, medication, and in severe cases, surgery.
