Abstract

BACKGROUND:

Lumbar spinal stenosis (LSS) is often a position-dependent condition that is aggravated in extension and relieved in flexion.

METHODS:

Ten consecutive elderly patients with LSS were assessed postoperatively by magnetic resonance imaging and the Swiss Spinal Stenosis Questionnaire. Cross-sectional areas of the dural sac and intervertebral foramina at the stenotic level were measured postoperatively and compared with the preoperative values.

RESULTS:

Postoperatively the cross-sectional area of the dural sac increased 16.6 mm2 or 22.3% and intervertebral foramina increased 22 mm2 or 36.5%. The intervertebral angle and the posterior disc height changed significantly. Seventy percent of the patients were satisfied with the surgical outcome.

CONCLUSION:

This new surgical method is effective in elderly LSS patients.
