The prognosis of conservative treatment of herniated lumbar discs is equivalent to operative treatment unless there is an absolute indication to operate. 85% of 58 patients with a proven herniated disc could be dismissed from the hospital in a satisfying condition, that is with working ability. 8 patients (12%) were operated, 3 of them at their own request. 2.5 years after the treatment in our hospital, a catamnesis of 30 patients showed positive results, only 4 patients had to undergo an operation.
