19例腰椎退行性疾病行棘突间动态稳定装置治疗的早期临床观察

Early evaluation of posterior dynamic stabilizaiton system combined with internal fixation in 19 patient

目的观察Willis棘突间动态固定装置治疗腰椎退行性疾病的早期临床疗效,探讨其适应证及优缺点。方法 2010-03-2011-03,对我院19例接受Willis装置治疗的腰椎退行性疾病患者进行观察随访,对比治疗前后患者JOA评分、Oswestry功能障碍指数的变化。结果 19例患者均获3~12个月随访,平均8.6个月。术后患者腰腿痛症状明显改善,JOA评分术前（21.7±1.03）分,术后（6.5±1.56）分;ODI评分由术前（49.5±1.6）分下降至（12.1±5.1）分。无硬脊膜撕裂脑脊液漏、术后感染、棘突骨折、神经损伤、植入物移位等并发症发生,无患者复发和需要翻修。结论 Willis系统治疗腰椎退行性疾病有良好疗效,是一种可靠安全的方法,但临床远期效果有待观察。

Objective To evaluate the early effect of Willis system in the treatment of lumbar degenerative disease,and to discuss the indication and advantages and defects of the Willis.Methods 19 patients suffering from lumbar degenerative disease were selected,all of them were treated with decompression,posterior implantation of Willis dynamic stabilization system.Japanese Orthopedic Association（JOA）scores for low back pain and Oswestry disability index（ODI）were used to evaluate clinical outcomes.Results Mean duration of 8.6 month follow-up ranging from 3~12 months were conducted on all the patients.The mean preoperativeJOA of 21.7±1.03 dropped to 6.5±1.56,and the mean preoperativeODI of 49.5±1.6 dropped to 12.1±5.1.No leakage of cerebrospinal fluid,infection or spinous process fracture,nerve injury,recurrence of inteverteabral disk hernia no displace of the Willis system were found.Conclusion The application of Willis system can achieve short-term satisfactory effects for the treatment of lmubar degenerative diseases.
