Scapula of a Human Male With Multiple Fractures, Posterior View

Description

Posterior anatomy of the male shoulder girdle centers on the scapula resting against the upper thoracic cage, with fracture lines crossing the scapular body and tracking laterally toward the thick axillary (lateral) border. The scapular spine runs transversely to the acromion, separating the supraspinous fossa superiorly from the infraspinous fossa inferiorly, while the medial (vertebral) border and inferior angle outline the bone’s triangular profile. Laterally, the glenoid cavity faces anterolaterally to accept the humeral head, which remains seated at the glenohumeral joint despite the adjacent bony disruption. Red fracture markings emphasize the multiplicity and intersecting directions of the breaks. Scapular fractures usually follow high-energy mechanisms, classically motor vehicle collisions or falls from height, and their presence should trigger a search for associated injuries across the chest wall and shoulder. Patterns extending to the lateral border raise concern for involvement of the glenoid neck and the scapulothoracic suspensory complex, injuries that can destabilize the shoulder ring and change management from sling immobilization to operative fixation. Don’t miss the company they keep. Rib fractures, pulmonary contusion or pneumothorax, and traction injury to the brachial plexus or axillary artery can accompany this level of trauma, and a posterior view clarifies why the scapula behaves as a shield over the thorax. Use this illustration in trauma education modules to teach scapular fracture classification and to orient learners to key posterior landmarks, including the spine, acromion, and borders that guide CT interpretation and surgical approaches. It also fits orthopaedic and radiology publications discussing operative indications for glenoid neck or lateral border fractures and the relationship of the scapula to the ribs during scapulothoracic motion.
