Cage加椎弓根螺钉固定治疗腰椎滑脱症的临床疗效

Cage Pedicle Screw Fixation for the Treatment of Lumbar Spondylolisthesis

目的：评价后路减压固定加椎间cage融合术治疗腰椎滑脱症的临床疗效。方法：自2009年3月-2013年6月应用椎间cage加椎弓根螺钉固定技术治疗腰椎滑脱症患者22例，其中男13例，女9例，年龄41-67岁，平均48岁。其中Ⅰ度滑脱14例，Ⅱ度滑脱7例，Ⅲ度滑脱1例。对所有患者术后随访3个月-32个月，平均28个月。结果：所有滑脱基本复位，融合率100％，椎体间高度恢复，症状明显改善， cage位置正常，椎弓根螺钉无松动及断裂。根据邹德威等评分标准，优良率达95．46％。结论：采用cage加椎弓根螺钉固定治疗腰椎滑脱症临床效果好、安全，椎间融合率高，内固定物无断裂、松动，是较为理想的手术方法之一。

Objective：To research the clinical efficacy of posterior decompression and interbody cage fusion in the treatment of lumbar spondylolisthesis.Methods：From march 2009 to june 2013,I applied interbody fusion and pedicle screw in the treatment of 22 patients with lumbar spondylolisthesis, including 13 males and 9 females, aged 41-67 years, mean 48years old, type I spondylolisthesis 14cases t,ype II spondylolisthesis 7 cases, and III spondylolisthesis patients. All patients were followed up for 3 months to 32months , with an average of 28 months.Results：All the cases slippage were reseted. ,the fusion rate was 100%, the vertebral height and symptoms after operation improved significantly, the cage remain the normal position and the pedicle screw not be loosening and fracture. The excellent rate is 95.46%, ac-cording to the Zou Dewei rating criteria. Conclusion：The fixation with cage and pedicle screw in the treatment of lumbar spondylolisthesis is one of the good methods have the advantages of more safety , interbody fusion rate fixation , without fracture and loosening.
