椎弓根钉内固定结合不同椎间融合方法治疗严重腰椎滑脱早期效果的比较

目的比较椎弓根钉内固定结合不同椎间融合方法治疗严重腰椎滑脱的疗效差异。方法对严重腰椎滑脱患者64例行后路椎弓根螺钉内固定,根据椎间融合方法的不同分为Cage融合组(32例)和椎间植骨组(32例)。比较术后两组的临床疗效、植骨融合率、Tailard滑脱率、腰椎前凸角和滑脱椎椎间高度指数等差异。结果64例均获随访,时间6～36(21.5±2.1)个月,患者均获解剖复位。Cage融合组JOA评分优良率和植骨融合率优于椎间植骨组(优良率90.6%、68.8%;融合率:84.4%、62.5%),两组比较差异有统计学意义(P0.05)。Tailard滑脱率、腰椎前凸角和滑脱椎椎间高度指数等指标两组比较差异也有统计学意义(P0.05)。结论椎弓根钉内固定系统结合Cage植骨治疗严重腰椎滑脱的早期临床疗效优于椎间植骨。

Short-term effect of severe lumbar spondylolisthesis treated with pedicle screw system internal fixation combined with different intervertebral fusions

Objective To compare the clinical effect in severe lumbar spondylolisthesis treated with pedicle screw system internal fixation combined with different intervertebral fusions.Methods Sixty four severe lumbar spondylolisthesis patients were divided into Cage implantation group(n=32) and intervertebral bone graft group(n=32) on the basis of pedicle screw system internal fixation.The effects were compared by clinical effect,rate of bone graft fusion,rate of Tailard spondylolisthesis,lumbar segmental lordosis a...
