The shoulder consists of the scapula (shoulder blade), coracoid, and humerus (upper arm). The fibers concerned with the cranial displacement of the scapula became the levator scapulae. The shoulder joint is positioned on the border between the scapula and the coracoid. The serratus dorsalis is medial to both the scapula and the serratus ventralis. A winged scapula due to serratus anterior palsy is rare. Scapular fractures involving the neck of the scapula have two patterns. The latissimus dorsi crosses the inferior angle of the scapula. Trapezius&colon; originates on the supraspinous ligament and inserts on the spine of the scapula. The superior angle of the scapula or medial angle, is covered by the trapezius muscle. The scapula and humerus are fan-shaped and wider than tall. Articulated with the scapula, the coracoid is sub-circular. It originates at the spine of the scapula and inserts at the deltoid ridge. The supraspinatus also originates on the spine of the scapula. Movements of the scapula are brought about by the scapular muscles. The scapulas become downwardly rotated and protracted, resulting in winged scapula and sloping shoulders.
