Medial Epicondyle Of The Humerus Shown, Anterior View

Description

Medial epicondyle of the distal humerus dominates the anterior aspect of the elbow in this illustration, projecting medially from the metaphyseal flare just proximal to the trochlea. From this fixed anterior perspective, the epicondylar prominence sits medial to the coronoid and radial fossae region and proximal to the ulnohumeral joint line, with the shaft of the humerus extending superiorly in anatomical position. The bony contour suggests the transition from the smooth articular surface of the trochlea to the nonarticular epicondylar cortex, a relationship that helps orient medial versus lateral landmarks at the distal humerus. Edges are crisp. Clinically, the medial epicondyle is the key palpable landmark for localizing the ulnar nerve as it passes posteriorly in the cubital tunnel, and it anchors the common flexor tendon origin (including pronator teres, flexor carpi radialis, palmaris longus, flexor carpi ulnaris, and flexor digitorum superficialis) along with the anterior bundle of the ulnar collateral ligament. That anatomy explains the pain pattern of medial epicondylitis (golfer’s elbow) and the valgus instability seen in overhead throwers with UCL injury, while pediatric avulsion fractures of the medial epicondyle remain a common elbow trauma associated with dislocation. The anterior view favors teaching of surface anatomy and attachment sites without visual interference from the olecranon and posterior distal humeral ridges. Use this illustration in upper limb anatomy labs, orthopedic and sports medicine lecture decks on elbow tendinopathy and UCL reconstruction, and surgical atlases discussing medial exposure of the distal humerus and ulnar nerve decompression or transposition. It also suits exam figures that test identification of distal humeral landmarks in anterior orientation. Anatomical accuracy verified by SciePro's Medical Advisory Board.
