腰椎后路Cosmic非融合固定与Coflex非融合固定的疗效对比

目的比较Cosmic非融合固定与Coflex非融合固定治疗退行性腰椎疾病的疗效。方法2009年8月--2012年8月杭州市第一人民医院骨科收治的退行性腰椎疾病患者60例，根据随机原则分为Cosmic组和Coflex组，每组30例。对2组患者的临床指标、疗效、VAS评分、JOA评分和ODI指数进行比较。结果Cosmic组的总有效率为100％，显著高于Coflex组（93．3％），差异具有统计学意义（P〈0．05）；Cosmic组的JOA评分显著高于Coflex组，ODI指数显著低于Coflex组，差异均具有统计学意义（t=2．120，2．104，P〈0．05）。结论Cosmic非融合固定术治疗退行性椎间盘疾病的综合疗效优于Coflex非融合固定。

Efficacy comparison of posterior lumbar Cosmic non-fusion fixation and Cofiex non-fusion fixation

Abstract：Objective To compare the efficacy of Cosmic non-fusion fixed and Coflex non-fusion fixed for the treatment of degenerative lumbar disease. Methods 60 patients with degenerative lumbar disease received in our hospital from Aug 2009 to Aug 2012 were divided into Cosmic group and Coflex group according to the random principle, with 30 cases in each group. Clinical indicators, efficacy, VAS score, JOA score and ODI Index of the two groups of patients were com- pared. Results The total effective rate in Cosmic group was 100% , significantly higher than that of the Coflex group （ 93.3 % ） , the difference was statistically significant （ P 〈 O. 05 ） ; JOA score in Cosmic group was significantly higher than that of Coflex group, ODI index was significantly lower than that of Coflex group, the differences were statistically signifi- cant （ t = 2.120,2. 104, P 〈 0.05 ）. Conclusion The efficacy of Cosmic non-fusion fixation for the treatment of degenera- tive disc disease was better than Coflex non-fusion fixation.
