Scapulothoracic Joint Definition

The scapulothoracic joint is not considered a true joint as it does not contain a synovial membrane and does not have ligaments connecting to the bone. It is located where the shoulder blade glides against the thoracic rib cage at the back of the body and is one of the four joints that complete the shoulder joint. The scapulothoracic joint facilitates the up and down movement of the arm.

Scapulothoracic bursitis, or snapping scapula syndrome, is an arthritic condition that can affect the scapulothoracic joint in young athletic patients.
