Abstract |
Objectives: The purpose of this study is to describe the surgical techniques of simple ligamentectomy without fusion for the treatment of lumbar stenosis and to review the postoperative outcomes in resolution of pain and improvement of functional status.
Methods: The authors reviewed clinical and radiologic findings of 458 patients with lumbar spinal stenosis underwent simple ligamentectomy between January 1998 and December 2003. Preoperative and postoperative clinical symptoms and neurologic functional status were reviewed along with complication to evaluate the efficacy of the surgery.
Results: Mean follow-up period was 4 years. Back pain and leg pain measured by VAS score was improved such as preopertative 5.9±2.8 to postoperative 3.1±3.0 and 7.4±2.4 to 2.9±2.6, respectively. Walking difficulty(preoperative 7.7 ±2.2) was improved to 3.3±3.2 postoperatively. There were no facet fracture, recurrence of radicular pain, instability and neurogenic intermittent claudication during the follow-up period.
Conclusions: This sublaminar ligamentectomy in lumbar spinal stenosis did not cause weakness of lamina and prevented fracture of inferior articular process and provided satisfactory postoperative results without recurrence. This procedure has been found to be an effective and safe procedure with rare complications. |
