摘要
目的:观察Dynesys非融合系统治疗70岁以上高龄腰椎管狭窄症近期及中期疗效。方法:2011年4月至2016年4月,对我科经症状及动力位X片、CT、MRI、骨密度检测等资料确诊的28例70岁以上排除严重骨质疏松症腰椎管狭窄症患者行了Dynesys动态非融合螺钉固定结合全椎板切除减压手术,术后随访(60-24)个月,分别对术前1天、术后3个月、末次随访VAS评分、ODI评分、腰椎正侧位X片进行分析比较。结果:28例患者均受到回访,术后1年较术后3月无明显改变。术后5年患者螺钉周围出现骨小梁稀疏,但是未见螺钉松动断裂。结论:Dynesys非融合螺钉的设计有利于骨长入,在非严重骨质疏症并且配合抗骨质疏松治疗的70岁以上高龄腰椎管狭窄症患者应用中近期及中期疗效肯定。
