[Epicondylitis humeri (tennis elbow)].

Epicondylitis is mostly related to a tendinosis found in the region of the radial or ulnar epicondylus, where the common origin of the extensor or flexor muscles is anchored. Several causes are associated with the etiopatho-genesis, most important is mechanical stress. The working hand is involved in the majority of cases. The age of the patients ranges mainly from 40-60 years. In 90% of the cases conservative measures are successful; if surgical treatment is necessary we recommend a modified version of Hohmann's operation.
