电磁导航引导经皮椎间孔镜治疗退变性腰椎管狭窄症的临床研究

目的 观察电磁导航引导经皮椎间孔镜治疗退变性腰椎管狭窄症的临床效果。 方法 采取回顾性队列研究。收集我院骨科2018年9月~2019年9月椎间孔镜治疗的退变性腰椎管狭窄症患者63例，分为导航组（27例）和常规组（36例）。记录两组人口学特征及手术相关指标，采用VAS、JOA评分评价临床疗效。 结果 两组人口学和术前临床特征比较，差异无统计学意义（P>0.05）。两组术中透视次数、穿刺及手术时间、术后住院时间比较，差异有统计学意义（P<0.05），腿痛VAS评分、JOA评分组内比较，差异有统计学意义（P<0.05）。两组术后复发率比较，差异无统计学意义（P>0.05）。 结论 电磁导航引导经皮椎间孔镜治疗腰椎管狭窄症，可以减少透视次数、穿刺和手术时间、术后住院时间，降低术中辐射暴露，提升穿刺定位效率。

Clinical study of degenerative lumbar spinal stenosis with percutaneous endoscopic guided by electromagnetic navigation

Objective To explore the clinical application value of degenerative lumbar spinal stenosis through the intervertebral foramen with percutaneous endoscopic guided by electromagnetic navigation. Methods A retrospective cohort study was performed. From Sep 2018 to Sep 2019, 63 patients with degenerative lumbar spinal stenosis were treated with percutaneous endoscopic, who were divided into a navigation group (n=27) and a conventional group (n=36). The demographic characteristics and operation-related indexes of the two groups were recorded. Visual analog scale (VAS) and Japanese Orthopedic Association scores (JOA) were used to evaluate and analyze the clinical efficacy. Results There was no significant difference in the demographic characteristics and preoperative clinical features between the two groups (P>0.05). There were significant differences in fluoroscopy times, puncture and operation time, postoperative hospital stays between the two group (P<0.05), and there were significant differences in VAS score and JOA score of leg pain preoperative and postoperative in each group (P<0.05). There was no significant difference in the recurrence rate between the two groups (P>0.05). Conclusions Percutaneous endoscopic treatment of lumbar spinal stenosis guided by electromagnetic navigation can reduce the fluoroscopy times, puncture and operation time, postoperative hospital stays, thus reducing the radiation exposure during operation and improving the efficiency of positioning and punctruing.
