Wallis动态稳定系统治疗腰椎间盘突出症临床研究

A clinical study on the Wagis dynamic stabilization system in the treatment of lumbar disc herniation

目的 研究Wallis棘突间态稳定系统在腰椎间盘突出症治疗中的早期疗效；是否有效减少腰椎间盘摘除术后早期复查、减缓腰椎退变.方法 对108例腰椎间盘突出症患者行开窗髓核摘除术,术中植入Wallis棘突间动态稳定系统,观察手术操作过程、手术用时、术中出血量及术后早期恢复情况,并通过VAS评分、JOA评分进行术前术后评估.结果 Wallis棘突间动态稳定系统植入手术操作简单,用时短,组织损伤小,术后恢复顺利,术后3天VAS评分（3.5±1.0）分,术后7天（2.3±0.5）分,JOA评分术后1个月（25.1±1.2）分,术后6个月（24.5±2.0）分.结论 Wallis棘突间动态稳定系统治疗伴有腰椎退变的腰椎间盘突出症安全简便,早期效果良好,有效减少短期椎间盘术后复发.

Objective To explore the early efficacy of the Wallis interspinous dynamic stabilization system in the treatment of lumbar disc herniation,and whether to reduce early reexamination after lumbar discectomy and to reduce degenerative of lumbar vertebra.Methods 108 patients with lumbar disc herniation received fenestration discectomy and implantation of the Wallis interspinous dynamic stabilization system.The surgical process,surgical duration,amount of intraoperative bleeding,and early postoperative recovery were observed; The VAS scores and JOA scores were used for pre-and post-operative assessment.Results The procedure for implanting Wallis interspinous dynamic stabilization system was simple and had shorter duration.The patients has less injury and quicker postoperative recovery.The VAS score was 3.5 ± 1.0 on day 3 and 2.3 ± 0.5 on day 7 after surgery; the JOA score was 25.1-＋ 1.2 on month 1 and 24.5 ± 2.0 on month 6.Conclusions Wallis interspinous dynamic stabilization system is safe,simple,and efficacious in the treatment of lumbar disc herniation complicated by lumbar spinal degeneration.It can effectively reduce the short-term postoperative recurrence of lumbar disc herniation.
