Coflex棘突间动态稳定系统治疗青壮年单节段腰椎间盘突出症的临床观察

The clinical observation of Coflex interspinous dynamic stabilization system on treatment of mono-segment prolapse of lumbar intervertebral disc in young adults

目的探讨Coflex棘突间动态稳定系统在青壮年单节段腰椎间盘突出症的应用趋向。方法回顾性分析2009年8月～2012年4月采用Coflex内固定手术治疗18例青壮年单节段腰椎间盘突出症的临床资料,通过记录手术时间、出血量、JOA评分、VAS评分,评价手术疗效,随访其有无动态稳定系统相关并发症。结果术后3d、1个月VAS评分及术后1、3、6个月JOA评分与术前比较,差异有统计学意义(P<0.05);术后随访JOA评分改善率为100%,无感染、脑脊液漏、神经损伤、植入物移位等并发症。结论 Coflex棘突动态稳定系统治疗腰椎间盘突出,创伤小,手术时间短,术后能早期下地活动,初期疗效良好,是治疗青壮年腰椎间盘突出症的好方法。

Objective To explore the application tendency of Coflex interspinous dynamic and stable system of treatment on mono-segment prolapse of lumbar intervertebral disc in young adults.Methods 18 young adults with monosegment prolapse of lumbar intervertebral disc treated by Coflex internal fixation from August 2009 to April 2012 were retrospectively analyzed.The surgical effects were evaluated by operation time,blood loss,JOA score,VAS score,and whether there were complications related with dynamic stabilization system was collected by follow-up.Results The VAS score 3 days and 1 month after surgery and JOA score 1,3,6 months after surgery were statistical difference compared with before surgery（P＆lt;0.05）.The post-operation follow-up displayed improvement of JOA score in 100% and had no complications such as infection,leakage of cerebrospinal fluid,nerve injury,and shift of the implant.Conclusion The treatment of mono-segment prolapse of lumbar intervertebral disc with Coflex interspinous dynamic stabilization system has the advantages of little wound,short operation time,being out of bed at early time after surgery,obtains a good effect at an early stage.It is a satisfactory way to treat mono-segment prolapse of lumbar intervertebral disc in young adults.
