摘要

Background context: There are few prospective studies on dural lesions in lumbar spinal stenosis surgery regarding incidence and effect on long-term outcome.Purpose: To determine the incidence of peroperative dural lesions in spinal stenosis surgery and their effect on one-year postoperative outcome.Study design/setting: Prospective cohort study (Swedish Spine Register) with a one-year follow-up.Patient sample: A five-year material of patients undergoing surgery for lumbar spinal stenosis. In total 3 699 patients were included, 935 of which underwent a fusion in conjunction with a decompressive operation and 2 764 who had decompressive surgery only. 44% were males. Mean age was 65 for fused and 68 for non-fused patients. Outcome measures: The Swedish Spine Register protocol including patient based pre- and postoperative data such as consumption of analgesics, walking distance, VAS pain, SF-36, Oswestry score and global outcome assessment.
