摘要 目的评价短节段椎弓根螺钉加椎间融合器治疗腰椎滑脱症的临床疗效。方法 2006年3月~2010年8月我院采用短节段椎弓根螺钉结合椎间融合器内固定治疗腰椎滑脱症患者,资料完整的病例132例,男74例,女58例,年龄36~75岁,平均52岁。失稳节段:L3/L4,12例;L4/L5,63例;L5/S1,57例。采用NaKai评定标准判定术后疗效,观察术后失稳椎体间有无移位,椎弓根螺钉及椎间融合器位置情况;测量术前、术后1周、术后16个月失稳椎间隙高度与上位椎间隙高度的比值。结果手术时间1.5~3h,平均2 h;术中出血量200~600ml,平均490ml。并发硬膜囊撕裂11例,神经根牵拉伤8例。随访时间2月多~53月,平均30月,术后腰椎序列恢复正常;术后16个月时按NaKai标准评定,优98例,良26例,可8例,优良率93.9%;术后16个月时,椎间融合率为100%;末次随访时无失稳复发,椎弓根螺钉及椎间融合器均无松动、移位等。结论短节段椎弓根螺钉加单枚椎间融合器内固定是治疗腰椎失稳症比较可靠的方法,能很好地维持椎间隙的高度和节段的稳定。
