Surgery for lumbar spinal stenosis in old people

Abstract

We have reviewed 31 consecutive patients, aged 65 years or more, after surgical decompression for degenerative lumbar spinal stenosis. The average follow-up was 42 months. Assessment included a standard questionnaire, a pain diagram which was completed by the patient, and clinical and radiological examination. Patients were considered in three groups; degenerative spondylolisthesis (19), lateral recess stenosis (5), and central-mixed stenosis (7). The indication for surgery was leg pain: no patient had an operation for back pain alone. Fusion was never performed. Overall, 64% of the patients had an excellent result, 17% a good result and 19% a poor result. We conclude that the long-term outcome of decompressive surgery in the elderly is good; it does not differ from that reported for younger patients.
