目的：研究椎间盘镜经脊柱后路治疗L4-5椎间孔狭窄的疗效情况。方法：自2012年3月至2013年3月，于我院共计有46例病患被确诊。以数字法随机分成观察组（23例）和对照组（23例）。对照组行肌间隙入路椎间融合术式治疗，观察组则行椎间盘镜经脊柱后路术式治疗。对比两个组别不同治疗术式疗效以及治疗前后JOA评分。结果：观察组优为73．91％（17/23），总有效率为95．65％（22/23），显著高于对照组43．48％（10/23），73．91％（17/23）。差异均有统计学意义（均P＜0．05）。观察组在治疗后3个月的JOA评分为24．1±1．2，治疗后6个月的JOA评分为24．4±1．1，治疗后12个月的JOA评分为24．5±1．4，均显著高于对照组23．5±0．7，23．7±1．0，23．7±1．2。差异均有统计学意义（均P＜0．05）。结论：以椎间盘镜经脊柱后路进行治疗L4-5椎间孔狭窄，疗效更佳，同时可明显提升病患JOA评分，促进病患恢复，值得临床推荐。%Objective:To study the effect of posterior spinal diskoscope (PSD) in treating L4-5 forami-nal stenosis .Method:From March 2012 to March 2013 , a total of 46 cases of patients in our hospital were diagnosed with the disease .They were randomly divided into the observation group (23 cases) and the con-trol group (23 cases) according to digital method.The control group was treated with muscle gap approach interbody fusion.While the observation group was treated with PSD , and then compared curative effect of 2 groups in different surgeries and JOA scores before and after treatment .Result:The excellent rate of the ob-servation group was 73.91%(17/23), the total effective rate was 95.65%(22/23), which were significant-ly higher than the control group of 43.48%(10/23), 73.91%(17/23).There's statistically significant differences (all P <0.05).The observation group’s JOA score was 24.1 ±1.2 after 3 months, 24.4 ±1.1 af-ter 6 months, was 24.5 ±1.4 after 12 months, which were significantly higher than the control group of 23. 5 ±0.7, 23.7 ±1.0, 23.7 ±1.2.There's statistically significant Differences (all P <0.05).Conclusion:The PSD in treating foraminal stenosis has better efficacy , and can significantly enhance the patients ’ JOA score , promote patient recovery .It is worthy of recommendation .
