前路与后路Cage植骨加椎弓根钉内固定治疗腰椎滑脱症疗效比较

目的探讨前路Cage植骨加椎弓根螺钉内固定与后路Cage植骨加椎弓根钉内固定治疗腰椎滑脱症两种术式的临床效果。方法43例患者按手术方式分为两组：前路Cage植骨加椎弓根钉内固定组（A组）17例,后路Cage植骨加椎弓根钉内固定组（B组）26例,对两组的手术时间、术中出血量、临床疗效（JOA评分）、X线融合率及并发症进行比较分析。结果A组的手术时间及术中出血量均明显多于B组（P〈0.05）,两组患者在临床疗效、融合率方面差异无显著性（P〉0.05）;A组术后未见硬膜囊、神经根及大血管损伤,无逆行性射精及阳痿的并发症;B组术后有5例发生硬膜损伤、脑脊液漏,7例出现神经根牵拉表现。结论两种手术都是治疗腰椎滑脱症的有效术式。前路手术较复杂、创伤较大,后路手术损伤硬膜囊及神经根的风险较高。

Anterior versus posterior cage implantation for interbody fusion combined with posterior pedicle screw fixation in treating lumbar spondylolisthesis

Objective To compare the clinical outcomes of anterior and posterior interbody fusion cage implantation combined with posterior pedicle screw system in treating lumbar spondylolisthesis.Methods This retrospective study analysis was performed for the outcome of 43 patients with single level spondylolisthesis.All the patients were divided randomly into two groups: anterior lumbar fusion cage combined with posterior pedicle screw system(group A) was performed in 17 patients,and posterior lumbar interbody fusio...
