LONG-TERM OUTCOME OF SURGICAL TREATMENT FOR LUMBAR STENOSIS

Purpose: The quality of the functional result for surgical treatment of lumbar stenosis has been the subject of much debate. The objectives of this retrospective review were to assess functional outcome ten years after surgical treatment of lumbar stenosis and determine the rate of revision in order to identify factors influencing outcome at last follow-up.Material and methods: One hundred forty-one patients underwent surgery for lumbar stenosis between January 1990 and December 1992. Mean follow-up was ten years. Functional outcome at last follow-up was assessed with a specific questionnaire with items for lumbar and radicular pain and signs of radicular ischemia and with a self-administered satisfaction questionnaire as well as two visual analogue scales (VAS) for lumbar and radicular pain. Other data noted were: epidemiological and morphological features, comorbidity, presence or not of objective signs of neurological involvement, the SF-36, and a self-assessed anxiety-depression score (GHQ28).
