目的 探究克氏针引导大直径环锯一次性椎间孔成形技术用于椎间孔镜治疗腰椎间盘突出症的效果。方法 选取2017年1月—2019年12月收治的60例腰椎间盘突出患者,随机分为观察组和对照组,对观察组使用克氏针引导大直径环锯一次性椎间孔成形技术,对照组采用常规绿色、黄色和红色环锯依次扩大椎间孔,观察记录椎间孔成形时间、成形过程中透视次数、手术时间、手术前后视觉模拟评分和治疗效果。结果 观察组在椎间孔成形时间、成形过程中透视次数、手术时间等各项观察指标优于对照组,差异有统计学意义（P<0.05）。术后视觉模拟评分差异无统计学意义（P>0.05）。观察组治疗有效率与对照组差异无统计学意义（P>0.05）。两组患者的并发症情况差异无统计学意义。结论 克氏针引导大直径环锯一次性椎间孔成形技术用于椎间孔镜治疗腰椎间盘突出症效果显著,能够减少椎间孔成形时间以及患者手术时间,在临床治疗中值得推广。

Objective To explore the effects of one-step foraminoplasty technique with a Kirschner wire-guided large-diameter circular saw on lumbar disc herniation. Methods Sixty patients with lumbar disc herniation treated from January 2017 to December 2019 were selected and randomly divided into an experimental group and a control group. The experimental group was treated by one-step foraminoplasty technique with a Kirschner wire-guided large-diameter circular saw, and the control group was treated by conventional green, yellow, and red circular saws to enlarge the intervertebral foramen in turn. The time of intervertebral foramen forming, number of fluoroscopy, operation time, and visual analogue score before and after the operation, and treatment effect of the two groups were observed and recorded. Results The experimental group showed shorter intervertebral foramen forming time, smaller number of fluoroscopy, and less operation time than the control group did （P<0.05）. There were no significant differences in postoperative visual analogue score, treatment efficacy rate, and complications between the two groups （P>0.05）. Conclusion The one-step foraminoplasty with Kirschner wire-guided large-diameter circular saw is effective in the treatment of lumbar disc herniation. It can reduce the forming time of intervertebral foramen and the operation time of patients, and is worthy of promotion in clinical treatment.
