摘要
目的比较椎间融合器与椎弓根钉固定单独应用及二者联合应用治疗腰椎滑脱症的效果。方法102例腰椎滑脱症患者根据治疗方法不同分为3组:椎间融合器、椎弓根钉固定组(A组),单纯椎弓根钉固定组(B组),椎间融合器组(C组),3组均行椎间及后外侧植骨。对3组术前、术后和随访时JOA评分、滑脱率、复位率、滑脱角、椎间隙高度、椎间孔高度及并发症进行对比研究。结果3组术后较术前各项指标有明显改善(P<0.01);随访发现:B组、C组的复位率、滑脱角、椎间隙高度、椎间孔高度丢失程度较A组明显(P<0.05);B组、C组植骨融合失败率高(P<0.05);JOA评分A组优良率为93%,优于其他两组(P<0.05)。结论椎间融合器加椎弓根钉系统固定治疗腰椎滑脱症临床疗效肯定,并发症相对较少。
Objective To compare the therapeutic effect of intervertebral fusion device and pedicle screw fixation on treatment of spondylolisthesis.Methods One hundred and two patients with spondylolisthesis were divided into group A,group B and group C.Thirty one patients in group A were treated by intervertebral fusion device combined with pedicle screw fixation.Forty eight patients in group B were treated by pedicle screws fixation combined with posterolateral intervertebral bone grafting.Twenty three patients in group C were treated by intervertebral fusion device combined with posterolateral intervertebral bone grafting.The height of intervertebral space and foramen were measured postoperatively.The slippage rate,recurrence rate,JOA score and complications were observed respectively and were compared among three groups.Results All index were improved greatly after operation (P<0.01).The patients in group A were better than those in group B and group C in JOA score,intervertebral space,intervertebral foramen,angle of slippage and the rate of reduction.The failure rate of graft fusion were higher in group B and C than in group A(P<0.05).The JOA score in 93% patients of group A was good or excellent.Conclusion The intervertebral fusion device or pedicle screw fixation combined with posterolateral intervertebral bone grafting can gain good outcome and less complications in the treatment of spondylolisthesis.
