椎弓根螺钉联合椎间融合器治疗腰椎管狭窄合并腰椎失稳的疗效观察

[目的]探讨椎弓根螺钉联合椎闻融合器治疗腰椎管狭窄合并腰椎失稳的临床疗效. [方法]选择运城 市中心医院2009年4月～2011年2月腰椎管狭窄合并腰椎失稳38例患者,均采用椎弓根螺钉联合椎间融合器植骨融合 治疗.术后随访6～28个月,应用Oswestry功能障碍指数(Oswestry Disability Index,ODI)评分和视觉模拟疼痛评分法(Visual analogue scale,VAS)进行功能评估并测量腰椎前凸角和椎间隙高度,对临床疗效进行评价.[结果]本组患 者术后6周及最终随访ODI、VAS评分好较术前有明显改善,差异有统计学意义(P＜0.05).术后6周与随访时腰椎前 凸角及椎闻隙高度均较术前有明显改善,差异有统计学意义(P＜0.05).Henderson疗效评估结果为优12例,良23例, 可3例,无差例,优良率为92.11％.2例不融合,融合宰为94.74％. [结论]椎弓根螺钉系统联合椎间融合器治疗腰 椎管狭窄合并腰椎失稳能有效地改善ODI、ODI术后评分,维持术后椎闻隙高度,改善腰椎前凸角,融合率、优良率较 高,无严重并发症.是一种有效、可靠的治疗方法,值得临床推广.

OBSERVATION ON THE CLINICAL EFFECT OF COMBINATION OF PEDICLE SEREW AND CAGE IN TREATMENT OF STENOSIS OF THE LUMBAR SPINE COMBINED WITH LUMBAR INSTABILITY

[Objective]To explore the clinical effect of combination of pedicle serew and cage in treating degenerative lumbar spinal stenosis combined with lumbar instability.[Methods]38 patients with degenerative lumbar spinal stenosis combined with lumbar instability from Apr. 2009 to Feb.2011 were selected and received pedicle screw and cage. All patients were followed up from 6 to 28 months. Oswestry Disability Index(ODI)and visual analog scale(VAS)were used to evaluate the clinic results and lumbar lordosis angle...
