单切口Quardrant通道下misTLIF与改良PLIF治疗腰椎管狭窄症的疗效比较

Effect comparison between misTLIF with Quadrant passage by single incision and modified PLIF therapy in treating lumbar spinal stenosis

目的评估Quardrant通道下misTLIF治疗腰椎管狭窄的疗效,与改良PLIF手术进行比较。方法回顾分析85例腰椎管狭窄患者,根据手术方案分为A、B组,A组采用Quardrant通道下采用单侧减压融合(misTLIF)联合双侧椎弓根螺钉内固定手术治疗,B组采用行后路椎体间融合术(改良PLIF)治疗,比较2组患者术后疼痛VAS评分,JOA评分和功能障碍指数ODI评分。结果 A组患者手术出血量显著低于B组(P<0.05)。2组患者术后半年时JOA评分改善率相似。术后2年随访时,A组的ODI评分和VAS评分改善显著优于B组(P<0.05)。结论 Quardrant通道下单侧减压椎间融合双侧椎弓根螺钉固定治疗腰椎管狭窄疗效确切。

Objective To compare the efficacy of misTLIF with Quadrant passage by single incision and modified PLIF surgery in treatment of patients with lumbar spinal stenosis.Methods A total of 85 patients with lumbar spinal stenosis were divided into group A and group B.Group A was treated with misTLIF with Quadrant passage by single incision and bilateral pedicle screw fixation,while group B was treated with the modified PLIF.The postoperative VAS score,JOA score and ODI score were compared.Results The surgical blood loss of group A was significantly lower than group B（P〈0.05）.The JOA score improvement rate after treatment was similar between two groups.Two years later,the ODI score and VAS score in group A were significantly better than group B（P〈0.05）.Conclusion The misTLIF with Quadrant passage by single incision and bilateral pedicle screw fixation is effective in treatment of patients with lumbar spinal stenosis.
