摘    要:目的 探讨Dynesys 动态稳定系统在腰椎多节段退变性疾病治疗中的临床疗效.方法回顾性分析2009 年7月~2012年7月采用Dynesys动态固定系统治疗的多节段腰椎退变性疾病患者30例.其中男10例,女20例;年龄为30~64岁,平均49.2岁.患者中腰椎退变性侧凸L2/L3/L4/L5/S1 1例;腰椎椎管狭窄症16例,L1/L2/L3/L4/L5 1例,L2/L3/L4/L5/S1 1例,L3/L4/L5 3例,L4/L5/S111例; 椎间盘突出症13例,L4/L5 椎间盘突出合并L5/S1退变5例,L5 /S1椎间盘突出合并L4/L5退变4例,L4/L5/S1 双节段突出者4例.临床症状包括下腰痛、下肢放射痛以及间歇性跛行.所有患者均有腰痛和/或腿痛的症状,经非手术治疗>3个月无效.术前腰椎疼痛视觉模拟量表( visual analogue scale,VAS) 评分为6.30分(3~9分),腿痛VAS评分6.40分( 0~9分),Oswestry功能障碍指数(Oswestry disability index,ODI)为62.67%.测量术后末次随访时患者腰痛、腿痛的VAS评分及ODI.结果 患者随访12~48个月,平均25个月.患者腰痛VAS评分在末次随访时较术前有明显的降低(1.77分),腿痛VAS评分也较术前有明显的降低(1.36分),ODI较术前也有明显的降低(12.50%).与术前相比,差异均有统计学意义( P<0.05).结论 Dynesys 动态固定系统手术操作简单、易掌握,可避免融合术相关并发症,效果满意.其长期临床疗效还需长时间临床观察.

Abstract:Objective To explore the clinical efficacy of Dynesys system for treatment of multiple segment lumbar degenerative disc disease.Methods A total of 30 patients (10 males and 20 females) with lumbar degenerative disc disease treated with Dynesys system from July 2009 to July 2012 were retrospectively reviewed.There were 1 case having degenerative scoliosis, 16 cases having lumbar canal stenosis and 13 cases having lumbar disc herniation. The mean preoperative visual analogue scales(VAS) score was 6.3(3-9) for the low back pain and 6.4 (0-9) for the leg pain, and the mean Oswestry disability index (ODI) was 62.67%.Results The mean follow-up period of all patients was 25 months. The postoperative VAS score of the low back pain was significantly reduced compared with the preoperative one (P<0.05). The same reduction was also noticed in leg pain VAS score and ODI (P<0.05).Conclusion Dynamic fixation system Dynesys is simple and easy to master, and it can avoid fusion surgery-related complications. The clinical results is satisfactory. However,its long-term clinical efficacy should be verified with long time.
Keywords:Lumbar vertebrae  Low back pain  Spinal stenosis  Intervertebral disc displacement  Internal fixators
