MEDIAL EPICONDYLITIS / GOLFER'S ELBOW
Medial epicondylitis, is when the bony knob on the inner side of the elbow is inflamed. This occurs when the tissue that attaches muscle to the bone becomes irritated. This occurs following a repetitive activity such as hammering or use of a screwdriver. In athletes, the inciting activity involves wrist flexion and pronation (palm facing down) such as serving an overhead and forehand strokes. Golfing ("golfer's elbow") or throwing may also cause symptoms. Patients may also complain of pain or weakness on gripping.
Medial epicondylitis is believed to be a irritation of the origin of the wrist flexors at the elbow and the pronator teres muscle.
