腰椎椎管狭窄与椎间盘突出症关系的探讨

腰椎管狭窄常合并椎间盘突出较常见。根据临床特点将本组68例分为三种类型:(1)间歇性跛行型21例;(2)根性疼痛型42例;(3)间歇跛行-根性疼痛型5例。全部施行手术治疗,随访58例,平均访程22个月。优41例,良14例,无变化3例。本文对腰椎管狭窄与椎间盘并存者之病理、临床特征及诊治作了讨论。

Lumbar Spinal Stenosis Associated with Disc Protrusion

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.
