Fractured Humerus, Posterior View

Description

Posterior shoulder and brachium are rendered with the humerus semi-transparently overlaid by the soft tissues, so the proximal humeral shaft, surgical neck region, and the posterior aspect of the glenohumeral joint sit clearly against the scapula and clavicle. A transverse fracture line crosses the proximal humerus with surrounding erythematous emphasis, and the proximal fragment remains aligned toward the glenoid while the distal shaft continues inferiorly into the arm. Laterally, the humeral cortex tracks toward the deltoid insertion; medially, it approaches the long head of triceps corridor and the neurovascular plane that traverses the posterior shoulder. Clear spatial cues help orient superior-inferior and medial-lateral relationships. Proximal humerus fractures are common after a fall on an outstretched hand in older adults and after high-energy trauma in younger patients, and the posterior viewpoint is useful when teaching how displacement can be influenced by the rotator cuff (infraspinatus and teres minor posteriorly, subscapularis anteriorly) and by deltoid pull on the shaft. Axillary nerve and posterior circumflex humeral artery vulnerability at the surgical neck is the clinical takeaway, and this angle also reinforces why posterior swelling or ecchymosis around the deltoid can accompany occult fracture patterns. Painful limitation of abduction matters here. So does neurovascular exam. Use this artwork for orthopedic trauma lectures covering Neer classification, for surgical education discussing deltopectoral versus anterolateral approaches and their relationship to the axillary nerve, or for patient-facing materials explaining why proximal humerus fractures often require sling immobilization versus fixation or arthroplasty. It also fits radiology and anatomy curricula when correlating posterior surface landmarks with AP and scapular Y imaging. Anatomical accuracy verified by SciePro's Medical Advisory Board.
