Tennis / Golfer's Elbow

Lateral epicondylitis (tennis elbow): pain at lateral epicondyle, common extensor origin (extensor carpi radialis brevis tendinopathy). Worse on resisted wrist extension / gripping. Medial epicondylitis (golfer's elbow): pain at medial epicondyle, common flexor origin. Worse on resisted wrist flexion / pronation. Most common 40–50y; overuse, occupational (tennis / golf in minority). Examination: focal tenderness at epicondyle; pain on resisted wrist extension (lateral) / flexion (medial). MRI / USS — confirm tendinopathy / partial tear if uncertain or refractory. Differentials: cervical radiculopathy, ulnar / radial nerve entrapment, OA, RA, infection.
