Spinatous fossa

Spinatous Fossa

The spinatous fossa is a shallow depression found on the posterior aspect of the scapula, one of the major bones of the shoulder girdle. This anatomical feature is significant in the attachment of muscles and the overall function of the shoulder.

Anatomy

The spinatous fossa is located above the spine of the scapula, which divides the posterior surface of the scapula into two regions: the supraspinous fossa and the infraspinous fossa. The spinatous fossa is part of the supraspinous fossa, which is situated superior to the spine of the scapula.

Function

The primary function of the spinatous fossa is to serve as the origin for the supraspinatus muscle. This muscle is one of the four rotator cuff muscles and plays a crucial role in the abduction of the arm at the shoulder joint.

Clinical Significance

Injuries or conditions affecting the spinatous fossa, such as supraspinatus tendinitis or rotator cuff tears, can lead to significant shoulder pain and dysfunction. Proper diagnosis and treatment are essential for maintaining shoulder health and function.
