目的 探讨经皮置钉联合单侧开窗跨顶减压治疗双侧腰椎管狭窄症的临床疗效.方法 选择我院收治的双侧腰椎管狭窄症患者126例,随机分成两组,观察组采用经皮置钉联合单侧椎板开窗跨顶减压治疗,对照组采用开放置钉联合双侧半椎板切除椎管减压治疗.对两组患者一般手术指标、并发症、治疗后腰痛和腿痛VAS评分以及ODI评分等进行比较.结果 观察组的手术时间、出血量、住院时间以及住院费用上比对照组少.两组患者术后均无切口感染等并发症.两组患者术后腰痛和腿痛的VAS评分及ODI评分与术前相比差异有统计学意义.两组之间的腰痛和腿痛的VAS评分及ODI评分在术后6、12个月及末次随访相比较差异有统计学意义.但是两组术后3个月的腰痛和腿痛VAS评分及ODI评分相比差异无统计学意义.结论 经皮微创置钉联合单侧椎板开窗跨顶减压治疗双侧腰椎管狭窄症具有创伤小、出血少、住院时间短、恢复快等优点,值得临床推广.%Objective Clinical study on the treatment of bilateral lumbar spinal stenosis with percutane-ous fixation combined with unilateral open-ended spinal canal decompression. Methods 126 patients with bilater-al lumbar spinal stenosis admitted to our hospital were randomly divided into two groups.The observation group was treated by percutaneous nail combined with unilateral laminar fenestration,and the control group was treated by open reduction combined with bilateral hemi laminectomy and spinal canal decompression.The two groups of pa-tients with general surgical complications after treatment,index,lumbago and leg pain VAS score and ODI score were compared.Results The operation time of the observation group,the amount of bleeding,the time of hospital-ization and the cost of hospitalization were less than those of the control group.There were no complications such as incision infection after operation in the two groups.The two groups were statistically significant postoperative pain and leg pain VAS score and ODI score compared with preoperative difference.The two groups had statistical signifi-cance between low back and leg pain VAS score and ODI score after 6 and 12 months and last follow-up phase dif-ference.But the two groups after 3 months of lumbago and leg pain VAS score and ODI score had no significant dif-ference.Conclusions Percutaneous minimally invasive nail combined with unilateral laminar fenestration and de-compression for bilateral lumbar spinal stenosis has the advantages of less trauma,less bleeding,shorter hospitaliza-tion time and quicker recovery.It is worthy of clinical promotion.
