Abstract

The therapeutic results of operatively and conservatively treated patients with lumbar disc syndromes were reviewed in a retrospective study. The patients were treated during a 10-years period (1976-1985). A total of 330 patients with lumbar disc prolapses were treated in the hospital during this period 44% were treated surgically. The data on 100 operated and 100 conservatively treated cases, registered in this random test sample, have been compared with respect to: pain; neurological deficits; subjective problems and sociomedical questions. The average patient age of both groups was about 41 years, and the patients predominant were male (about 70%). The therapeutic results of both operatively and conservatively treated patients were good, which is also by the high percentage of employment (80%-90%) in the two treatment groups. The critical evaluation showed more neurological disturbances and limited vocational activity in the group of cases operated upon. More than 70% of the operated cases showed radicular syndromes of the follow-up examination although it was not of essential functional importance. The period inability to work and the percentage of disablement were also much higher in this group. The pain symptoms were particularly relevant in our examination. Only 12%-16% of the patients in the two groups that took part in the follow-up examinations reported freedom from pain. It was apparent that atypical pain syndromes were correlated with personality psychological disturbances. Nearly one-third of our patients mentioned psychological problems. The prognosis of the conservative treatment of lumbar disc prolapse was equivalent to operative therapy (disregarding the absolute indications for operations). There were no definite advantages found for either of the two methods of treatment. The necessity for a specialized follow-up treatment of patients with sciatica due to herniated lumbar discs is discussed, and differentiated selection for operative therapy is given. Here the treatment of pain should be considered most important.
