Since 1987, we have operated on 59 patient by laminectomy for lumbar spine, of which 37 patients were followed up and evaluated. The mean age of the patients at surgery was 71 years, ranging from 60 to 83 years. The average preoperative JOA increased (range: 15 to 24 points). Improrement was however not seen in spondylolisthesis patients. A longer follow-up shonld be necessary for lumbar spondylolisthesis.
