AbstractRetrospectively 93 consecutive patients operated on for lumbar disc herniation were studied in order to evaluate the prognostic value of symptoms (lumbar pain and sciatica) and sick-leave. Surgical results were evaluated 1-3 years postoperatively by a questionaire. The duration of the present attack of sciatica and sick-leave prior to surgery was significantly longer in the group with unsatisfactory outcome compared to the group with satisfactory outcome. Patients with duration of the present attack of sciatica of less than 6 months had a significantly better result concerning outcome compared to patients with duration of 6-12 months and more than 12 months. Patients who returned to the same type of work had a preoperatively statistically significant shorter duration of present sick-leave, compared to the patients who had changed the type of work and the patients who did not return to work. The patients with duration of their present sick-leave of less than 6 months had a significantly higher percentage of returning to the same type of work compared to patients with duration of their present sick-leave of 6-12 months and more than 12 months. We conclude that the duration of sciatica and sick-leave before the operation has value as predictive factors concerning the over-all result after surgery for lumbar disc herniation.
