Eight Year Outcome after Surgery for Lumbar Disc Herniation: A Comparison of Reoperated and not Reoperated Patients

摘要

A retrospective study of 211 patients with unilateral sciatica operated on for lumbar disc herniation during 1988 and 1989 was performed in order to compare the results of reoperated patients with the results of patients operated on only once. The patients completed a standardized questionnaire in 1997 which included questions about reoperations, back and leg pain, functional status and disability pension. Outcome scores were calculated, giving values from 0 (no painormal function) to 100 (totally disabled).
