Posterior Perspective of a Fractured Humerus

Description

Posterior anatomy of the right brachium is rendered as an isolated skeleton, with the scapula and proximal humerus aligned superiorly and the distal humerus tapering inferiorly toward the elbow. Along the posterior surface, the humeral shaft leads into the expanded distal metaphysis, where the medial supracondylar ridge forms a sharp longitudinal buttress on the medial side. A fracture line, color-accented in red, interrupts cortical continuity near the distal humerus, just proximal to the epicondylar region and adjacent to the supracondylar ridges. Portions of the posterior thoracic cage remain visible medially, providing orientation to the shoulder girdle. Distal humerus fractures at the supracondylar and supracondylar ridge level carry predictable neurovascular risk, and a posterior bony-only view makes those relationships easier to teach: the ulnar nerve tracks posterior to the medial epicondyle, the radial nerve crosses from posterior to anterior through the lateral intermuscular septum more proximally, and the brachial artery lies anterior in the cubital fossa despite being hidden from this angle. Reduction strategy and fixation planning depend on whether the fracture propagates toward the olecranon fossa and trochlea, or remains extra-articular with a stable column for plating. Common problems include elbow stiffness, malunion with cubitus varus, and delayed neuropathy. Distal humerus fractures are not forgiving. Use this artwork in orthopedic trauma lectures, anatomy labs covering the arm and elbow, and exam-prep materials that contrast supracondylar, intercondylar, and epicondylar injury patterns by landmark. It also fits patient-education sheets explaining why a distal humerus fracture can affect hand sensation or grip even when the break sits above the joint.
