The Anatomical Structure Of The Medial Epicondyle Of The Humerus

Description

Arising from the medial aspect of the distal humerus, the medial epicondyle projects inferiorly and slightly posteriorly relative to the medial supracondylar ridge and the articular trochlea. The animation orbits the elbow to establish the epicondyle’s relationship to the capitulum laterally and the olecranon fossa posteriorly, then tightens focus on its palpable subcutaneous contour along the medial elbow. As the viewpoint transitions from anterior to posteromedial, the common flexor tendon origin is introduced along the anteroinferior epicondylar surface, with the ulnar nerve traced as it passes posterior to the epicondyle within the cubital tunnel. Orientation matters. Medial epicondyle anatomy anchors several everyday clinical decisions, from localizing tenderness in medial epicondylitis (common flexor-pronator tendinopathy) to recognizing ulnar neuropathy when symptoms radiate into the ring and little fingers. Rotational sequencing clarifies why the ulnar nerve is exposed during trauma and why it can subluxate over the epicondyle with elbow flexion, a relationship that is hard to teach from a single still. The epicondyle also serves as a key landmark when discussing distal humerus fractures and pediatric avulsion injury patterns around the elbow. Use this animation in upper-limb anatomy and kinesiology lectures to pair surface landmarks with deeper relationships, or in orthopedics and sports medicine materials covering golfer’s elbow, cubital tunnel syndrome, and medial collateral ligament region orientation during elbow examination. It also fits surgical and procedural training modules that emphasize safe palpation, incision planning, and nerve awareness along the medial elbow.
