A Posterior View Of The Humerus Showing The Condyle

Description

Posterior anatomy of the distal humerus comes into focus as the animation settles on the elbow end of the arm bone, orienting the viewer from the shaft (proximal) down to the condylar region (distal). The trochlea lies medially and extends onto the posterior aspect, while the capitulum sits more lateral and anterior, only partly appreciated from behind as the sequence subtly adjusts angle and depth. Superior to the trochlea, the olecranon fossa is shown as a deep posterior depression, bounded by the medial and lateral epicondyles and continuous with the posterior cortical surface of the distal metaphysis. Clinical reading of the posterior distal humerus hinges on those landmarks. Olecranon fossa integrity and the relationship of the medial epicondyle to the trochlea frame common injury patterns, including supracondylar fractures and posterior elbow dislocations, and help explain why the ulnar nerve is vulnerable as it courses posterior to the medial epicondyle in the cubital tunnel. Motion in the animation clarifies how the ulna’s olecranon process seats into the olecranon fossa during extension, a spatial concept that is hard to teach with a single still. Use this asset in upper limb anatomy teaching for osteology and arthrology blocks, in orthopedic or emergency medicine materials discussing distal humeral fracture classification and elbow stability, or as a clean visual for publisher diagrams introducing the elbow joint’s bony constraints. Ideal for layering with separate content on the ulna, radius, and capsule when building a stepwise elbow module. Anatomical accuracy verified by SciePro's Medical Advisory Board.
