100 consecutive patients operated on for sciatica pain. Microsurgical discectomy between April 1984 and February 1985 were evaluated retrospectively. This paper gives preoperalive clinical data, endre- sults of surgery, rate of complications and true recurrent herniations.The results were good, both soon after operation and at later follow-up (between 1 and 3 years). Complete or significant pain relief was achieved in 92% of patients; %93 were able to return to their normal physical activities. The frequency of complications was significantly low.
