A prospective 5-year follow-up study of 276 patients hospitalized because of suspected lumbar disc herniation.

Abstract

The study consists of 276 patients who were hospitalized between 1980 and 1982 because of suspected lumbar disc herniation. Treatment choice was based on clinical indications only; no randomization was used. A total of 179 patients were treated surgically and 97 had continued conservative treatment. Both groups were followed-up 1 and 5 years later. Five-year follow-up results showed that 68% of operated patients still had pain in sciatic distribution and 21% were retired. Re-operation frequency was 13.8%. Of non-operated patients, 82% still had sciatica and 26% were retired. Reasons for outcome differences between the study groups are discussed.
