Lumbar Spinal Stenosis Associated with Disc Protrusion / 第二军医大学学报

ABSTRACT

Sixty-eight patients with a surgically proven lumbar stenosis associated with disc protrusion were studied retrospectively. According to the essential clinical feature the patients were divided into three groups Group 1, intermittent claudication (n=21), Group 2, low back pain associated with unilateral aciatic pain (n=42), and Group 3, intermittent claudication coexisting with bilateral or unilateral leg pain (n=5). The final diagnosis prior to operation was difficult to make. Surgical decompression of the spinal canal required removal of the portion of hypertrophied superior articular faced and prolapsed disc. Fifty-eight patients were followed up from 6 months to 6 years and 3 months. In 41 patients preoperative neurogenic symptoms completely disappeared, 14 still an occasinal bachache, existed and 3 moderate symptoms persisted postoperatively.
