摘　　要：作者对２０例纤维环膨隆型腰椎管狭窄患者只行狭窄节段彻底减压，即切除部分关节突、黄韧带及少量椎扳下缘，保留棘突、棘上韧带及棘间韧带，不切除膨隆的纤维环。术前行功能让脊髓造影及ＣＴＭ检查，准确定位狭窄节段。最长随访时间４年３个月，最短１年，优良率达９％。本术式不干扰椎管内结构，硬膜外出血少，减压引流彻底，对退变性节段性狭窄患者尤为适应。patients of lumbar spinal stenosis with bulging annuluses fibrosus were decompressed thoroughly. Facets, ligamenta flava and inferior lamina were partially removed with the remaining of spinous processes, supraspine and interspinal ligaments. The bulging annuluse were not resected. Myelography and postmyelography-CT scan were performed preoperatively so that the stenosed segments could be defined accurately. All patients were followed up for 1-4 years (average 2 years) postoperatively. 90% success rate was achieved. The new procedure without interfere the structure of lumbar spine. Epidural hemorrhage was minimized and the compressed nerve roots and cauda equina were relieved completely. The procedure is suitable for patients with degenerative segment stenosis.
