Also known as tennis elbow and epitrochlear bursitis, epicondylitis is inflammation of the forearm extensor supinator tendon fibers at their common attachment to the lateral humeral epicondyle. This inflammation produces acute or subacute pain.
Epicondylitis probably begins as a partial tear and is common among tennis players and people whose activities require a forceful grasp, wrist extension against resistance, or frequent rotation of the forearm. Untreated epicondylitis may become disabling.
Signs and symptoms
The patient’s initial symptom is elbow pain that gradually worsens and commonly radiates to the forearm and back of the hand whenever he grasps an object or twists his elbow.
