摘要(Abstract):
[目的]评价腰椎后路椎体间融合(posterior lumbar interbody fusion,PLIF)术中应用双Cage和局部自体附件骨的融合率及术后5年的临床疗效。[方法]回顾接受PLIF手术、椎体间植入双Cage与局部附件骨、并行椎弓根钉内固定的84例患者的住院病历,并通过随访获得患者术前、术后1年、3年、5年的影像学资料,了解病人的康复情况,并用Oswestry功能障碍指数(Oswestry disability index,ODI)进行评分,观察椎体融合情况、相邻椎间隙退变情况(adjacent segment degeneration,ASD)。[结果]单间隙固定、二间隙固定、三间隙固定的患者术后1年、5年ODI评分比术前均有显著性降低(P<0.01);术后1年与术后5年ODI评分均无显著性差异(P>0.05)。术后1年融合率均为94.95%,术后3年融合率均为100%。术后5年部分患者遗留腰部发困、发僵、下坠感等腰痛不适症状,发生率22.61%(19/84),尚不能认为单间隙固定、二间隙固定、三间隙固定腰部不适发生率有差别。术后5年相邻椎间隙退变发生率19.04%(16/84)。具有相应症状、体征伴有ODI评分增加的ASD发生率2.38%(2/84)。[结论]PLIF应用双Cage结合自体局部附件骨植入、椎弓根内固定治疗下腰椎疾病椎体融合率高,术后1年、术后5年ODI评价临床疗效好。部分病人术后遗留有腰部不适。术后5年ASD多是影像学上的变化,极少产生临床症状。
