[Long term results of radiotherapy of degenerative joint diseases (author's transl)]

At the Radiologic Department of The Städtisches Krankenhaus Passau, 473 patients with degenerative diseases in the big joints and the spine were irradiated with the caesium unit between 1971 and 1979. Among these patients, 249 could be followed up during a prolonged period (1/2 to 9 years, i.e. 4.2 years on an average). According to the categories of v. Pannewitz, 11% were pain-free at this moment, 21% showed an essential improvement, 29% showed an improvement, and 39% were not influenced by the treatment. 13.5% showed recurrent pains; these were mentioned as "not influenced" in the statistical analysis. It is proved that the relief of pain does not depend on the age of the patients, but on the anamnesis period, the results of the X-ray examination, and the degree of the restriction of mobility. Due to the delay of irradiation, a preliminary treatment mostly produces a less favorable radiotherapeutic result. Compared with other therapeutic methods, the long term results or radiotherapy of degenerative joint diseases are generally favorable. This conclusion is also confirmed by the results of patients checked up more than five years after the treatment.
