【摘要】 目的探讨Dynesys应用于腰椎(L4、5)退变性疾病的早期临床疗效及相关影像学改变。方法自2008年8月～2009年12月,采用椎板开窗减压或部分切除,减压后置入Dynesys系统装置治疗12例腰椎退变性疾病。结果术后随访14～28个月,ODI、VAS、JOA评分较术前明显改善(P<0.05),L4、5节段椎体的活动度(ROM)术后与术前相比差异有统计学意义(P<0.05)。结论 Dynesys系统保留了腰椎生理曲度和固定节段的活动度,延缓并减少邻近节段的退变,短期临床疗效满意,其长期疗效有待进一步观察。更多还原

【Abstract】 Objective To investigate clinical efficacy of Dynesys dynamic internal fixation system in treatment of degenerative lumbar(L4、5) disease.Methods From August 2008 to December 2009,Dynesys dynamic internal fixation was performed in a consecutive 12 patients.The patients were treated with limited laminectomy and implant with Dynesys device.Results The follow-up time ranged from 14～28 months,with the mean of 21.5 months.There were significant difference between preoperative ODI,VAS and JOA scores and postoperative ones(P <0.05).And there were significant difference in the L4、5 segment ROM between postoperative and preoperative.Conclusion The Dynesys system appears to be a useful and effective alternative in the surgical management of degenerative lumber disease,which keeps the integrity of anatomical structures,delays and reduces the degeneration of adjacent segments.However long-term follow-up is needed to evaluate clinical outcomes of the device.更多还原
