【摘要】 目的探讨后路显微内窥镜辅助下单cage和结合经皮单侧椎弓根钉内固定治疗退变性腰椎失稳症的疗效。方法回顾分析自2006年3月～2009年12月采用显微内窥镜辅助微创治疗腰椎失稳症133例,其中108例采用显微内窥镜下单cage椎间融合术(A组),25例采用显微内窥镜辅助下单cage结合单侧经皮椎弓根钉棒系统(SEXTANT)内固定术(B组)。结果两组均顺利完成手术,术中出血量、优良率及ODI改善率无差异。本组获14个月~5年的随访,A、B组优良率分别为85.2%、88.0%,两组近期疗效差异无统计学意义。结论显微内窥镜下单cage椎间融合术不论是否同时行单侧椎弓根钉固定,均能取得满意疗效,但使用内固定可降低椎间融合器移位的风险。更多还原

【Abstract】 Objective To investigate the therapeutic effect of two methods of micro-endoscopic in treating lumbar vertebral instability with single cage or single cage with unilateral pedicle screw fixation.Methods From March 2006 to March 2009,132 cases of lumbar vertebral instability accepted interbody fusion by micro-endoscopic,including 108 cases with single cage interbody fusion(group A) and 25 cases with single cage interbody fusion with unilateral pedicle screw fixation(group B).Results The operation of two groups was both successfully completed.Intraoperative blood loss,improvement rate of two groups had no difference.All patients were followed up for 14 months to 5 years,the excellent and good rate of A and B group was 85.2% and 88.0% respectively.There was no significant difference in the short-term curative effect between the two groups.Conclusion Single cage interbody fusion whether or not with unilateral pedicle screw fixation simultaneously by micro-endoscopic can get satisfactory therapeutic effect,but internal fixation can reduce the risk of cage displacement.更多还原
