[Not a Chronic Tennis Elbow].

Not a Chronic Tennis Elbow Abstract. Lateral elbow pain is a highly unspecific finding and may be caused by one of several possible differential diagnoses. Unfortunately, it is often assumed to be epicondylitis, commonly referred to as tennis elbow, although instability is a frequent cause in chronic cases. In the presented case, it is the less frequent nerve compression of the radial nerve which must also be considered, together with plica syndrome, osteochondritis dissecans and arthrosis of the radiocapitellar joint, as a differential diagnosis of lateral elbow pain.
