We reviewed 78 patients after surgical decompression for lumbar spinal canal stenosis. The average follow-up was two years four months. Two groups of patients were compared: the control group consisting of those aged si less than 70 years, and an elderly group in which patients were si more than 70 years. In regard to JOA score, both groups improved by 7.5 points after surgery. 84.1% of old patients had an excellent or good result.
