目的：观察Coflex 固定加椎板开窗减压在腰椎管狭窄症的疗效。方法：选择2009 年8月至2012 年8 月在我院治疗，经CT 诊断为腰椎椎管狭窄的患者82例，随机分为观察组和对照组，每组各41例。观察组行Conflex固定加椎板开窗减压治疗，对照组行常规手术治疗。观察和比较两者患者1 年后的健康情况、术后满意程度、VAS评分及Barthel指数。结果：观察组术后满意度 90.2%，对照组为65.9%，与对照组比较，观察组满意度更高，差异有统计学意义（X2=16.8,P<0.001）；两组患者健康情况的比较：观察组优良率（82.9%）较对照组（56.1%）高，两组健康情况相互比较差异有统计学意义（X2=17.1, P<0.001）；观察组随访VAS 评分 2.34± 1.02，对照组VAS 评分4.31± 1.33，两组VAS 评分比较差异均有统计学意义（t=7.43, P<0.0 01）；观察组Barthel 指数（92.3± 5.1）优于对照组（81.2± 4.2），差异有统计学意义（t=5.31, P<0.0 01）。结论：Conflex固定加椎板开窗减压对腰椎管狭窄症的疗效确切，不良反应少，值得在临床上推广。

英文摘要:

Objective:To observe the clinical efficacy of Coflex fixed Lamina windowing decompression in the treatment of lumbar spinal stenosis.Methods:82 patients who were diagnosed with lumbar spinal stenosis and treated between August 2009 and August 2012 in our hospital were divided into two groups randomly and equally. The treatment group had Coflex fixed Lamina windowing decompression while the control group had regular operation. During the one-year treatment, observe and compare the patient's health, postoperative satisfaction degree, VAS score and Barthel index of the two groups were observed and compared.Results:The postoperative satisfaction degree of the treatment group (90.2%) was higher than that (65.9%) of the control group, with statistical difference (x2=16.8, P<0.001). The treatment group had a good-health rate of 82.9%, higher than that of 56.1%for the control group, and the difference was statistical (x2=17.1,P<0.001). The VAS score was 2.34± 1.02 for treatment group, and was 4.31± 1.33 for control group, also with statistical difference (t=7.43, P<0.001). The Barthel index of the treatment group was 92.3± 5.1, higher than that (81.2± 4.2) in the control group, and there was statistical difference (t=5.31, P<0.0 01).Conclusion:The Coflex fixed Lamina windowing decompression had convincing and reliable curative effect in treating lumbar spinal stenonis, with less adverse reactions, and is worth promoting in clinic.
