钉棒系统在腰椎间盘突出症伴椎体滑脱中的应用

目的：探讨椎弓根内固定、椎体间植骨融合术在治疗腰椎间盘突出症伴椎体滑脱中的应用及其疗效。方法：对71例腰椎间盘突出症伴椎体滑脱患者行后路次全椎板切除减压、椎间盘髓核摘除、椎体间隙植骨融合、并行椎弓根内固定术。结果：71例患者随访6个月～3年（平均1.8年）,优良率为95.8%。本组3例患者术后出现暂时性神经根牵拉现象,1周后症状消失,无切口感染及其他并发症发生。6～12个月经X线片复查70例显示椎体间骨性融合。结论：腰椎间盘突出症伴椎体滑脱,在解除椎间盘突出压迫神经根的同时,行椎体间植骨融合和椎弓根内固定,能有效解除神经根的致压因素,提高植骨融合率,增加脊柱的稳定性,促进术后功能的恢复。

The applicatian of screw system in lumbar disc herniation with lumbar spondylolisthesis

Objective：To discuss the therapeutic effect of transpedicular screw fixation combined with intertransversal fusion procedures in lumbar disc herniation with lumbar spondylolisthesis.Methods：71 patients of lumbar disc herniation with lumbar spondylolisthesis were treated with the posterion-subtotal laminectomy for decompression,removal of nucleus pulposus,intertransversal fusion procedures and transpedicular screw fixation.Results：71 patients were followed up from 6 months to 3 years with an average of 1.8 years.The excellent and good race was 95.8%.3 cases had temporal nerve root drag after operation,and relieved after one week.No wound infection and other complications occurred.The interspinal sol id fusion was observed in 70 cases in X ray between 6 to 12 months after operation.Conclusion：In the treatment of lumbar disc herniation with lumbar spondylolisthesis,the operation can lift the oppression of nerve root from lumbar disc her niation,at the same time,intertransversal fusion procedures and transpedicular screw fixation can relieve the nerve com pression caused by factors effectively,improve the fusion rate to increase the stability of spine and promote functional re covery.
