Lateral Epicondyle Of The Humerus, Anterior View

Description

Lateral epicondyle of the humerus occupies the lateral margin of the distal brachium, projecting just proximal and lateral to the capitulum on an anterior elbow perspective. From this fixed anterior viewpoint, the lateral supracondylar ridge can be appreciated coursing proximally from the epicondyle, while the articular contour of the capitulum sits medial and slightly inferior, forming the humeral surface that will oppose the radial head. The epicondylar prominence reads as a nonarticular landmark, set lateral to the radial fossa and anterior to the posterolateral elbow groove where the ulnar nerve does not run. A palpable landmark. Clinical relevance concentrates at the epicondylar footprint where the common extensor tendon originates, including extensor carpi radialis brevis, extensor digitorum, and extensor carpi ulnaris, and where the lateral collateral ligament complex anchors, so this is the bony focus for lateral epicondylitis, varus posterolateral rotatory instability, and targeted corticosteroid or PRP injection planning. Because the view emphasizes the anterior contour of the distal humerus rather than the posterior olecranon fossa, it helps distinguish the epicondyle from the adjacent capitellar articular surface, a frequent point of confusion when correlating palpation findings with radiographs. The lateral epicondyle also sits near the course of the radial nerve as it transitions anteriorly around the lateral humerus, a relationship that informs surgical exposure and retractor placement during distal humeral fixation. Use this illustration in gross anatomy teaching for upper limb osteology, in sports medicine materials addressing tennis elbow, and in orthopaedic or physical therapy publications that map tender points and tendon origins around the lateral elbow.
