Shock-wave therapy for tennis and golfer's elbow--1 year follow-up.

Thirty patients with chronic medial epicondylitis were treated with low-energy shock waves. They received 500 impulses of 0.08 mJ/mm2 three times at weekly intervals. At 1 year follow-up examinations were performed. According to the Verhaar criteria, only seven patients reached excellent or good results. In eight cases a fair outcome was recorded, and in 14 patients the outcome was poor. Only six patients were satisfied with the treatment. The average relief of pain was 32%. These data were significantly worse than for identically treated patients with chronic tennis elbow. Thus, the question arises as to whether extracorporal shock-wave therapy is indicated in medial epicondylitis.
