Elbow Joint

Description

Posterior surface anatomy of the cubitus is presented on an adult Black male, with the elbow held in neutral extension so the olecranon lies centrally at the proximal ulna, just inferior to the distal humerus. Proximally, the triceps brachii tendon converges toward the olecranon, forming the dominant posterior contour, while the medial and lateral epicondyles sit on either side as palpable bony landmarks. Along the posteromedial aspect, the expected course of the ulnar nerve passes behind the medial epicondyle toward the cubital tunnel, a relationship often taught using surface cues rather than deep dissection. Clinically, this posterior perspective maps directly to exam and procedure. Olecranon bursitis presents as a focal swelling superficial to the olecranon, whereas triceps tendinopathy or rupture alters the tendon’s distal profile and weakens elbow extension on resisted testing. The view also supports discussion of ulnar neuropathy at the elbow, where repeated flexion and external pressure can irritate the nerve in the retroepicondylar groove, and it aligns with common posterior or posterolateral surgical exposures that respect the ulnar nerve and the triceps insertion. Use it for musculoskeletal anatomy labs, surface anatomy teaching, and orthopaedic or sports medicine content where accurate palpation landmarks matter.
