The semicircular notching of the aponeurosis recommended by G. Hohmann for the treatment of epicondylitis humeri has proved extremely successful in practice, provided it is correctly performed. Patients who experience no definite improvement after appropriate consultation and exhaustive conservative treatment should undergo this relatively harmless operation. Hospitalization and surgical treatment under general anesthetic with exsanguination in an extensive procedure are not necessary. Careful follow-up treatment, as appropriate in each case, appears more important, and in 97% of all cases results in complete restoration of function of the arm thus treated.
