Glenoid process of scapula

The glenoid process of the scapula is the process forming the lateral angle of the scapula. It contents the glenoid fossa, a shallow, pyriform articular surface located on the lateral angle of the scapula, serving as the socket for the humeral head in the glenohumeral (shoulder) joint. The glenoid fossa is bordered by a bony rim, which is variably shaped, most commonly oval, pear-shaped, or occasionally more circular.

The superior aspect of the glenoid process of the scapula is marked by the supraglenoid tubercle, which serves as the origin for the long head of the biceps brachii, while the inferior aspect is marked by the infraglenoid tubercle, origin of the long head of the triceps brachii. The articular surface is covered by hyaline cartilage and surrounded by the fibrocartilaginous glenoid labrum, which deepens the socket and provides attachment for the joint capsule and ligaments.
