Abstract
Among the 813 cases of radical sciatica in the five years from 1974 through 1978, 144 cases or 17.7% were treated as in-patients. In spite of various types of maintenance thera-py, surgery was performed in only 23 cases or 2.8%.
When the prognosis of the maintenance therapy and surgery groups was compared, it was found that there were no major differences between the two groups with respect to such factors as daily activities and recurrences.
