Function

A flat, triangular bone that forms the posterior part of the shoulder girdle. Provides attachment for numerous muscles and articulates with the clavicle and humerus.

Scapular fractures typically result from high-energy trauma and are often associated with thoracic injuries. Scapular winging occurs with long thoracic nerve palsy. The acromion process can impinge on the rotator cuff.
