寰椎后桥65例X线诊断分析

Radiological analysis of posterior bridge of the atlas

目的:通过对65例寰椎后桥X线诊断结果分析,加强对寰椎后桥影像诊断的重视。方法:回顾性分析2014年7月-2016年9月在山西中医学院附属医院放射科摄片的65例寰椎后桥患者X线表现,着重分析形态分类、X线表现与患者年龄分布的关系,依此推测其成因及临床症状。结果:65例患者,单纯后桥型20例,合并退变型分布25例,合并颈椎病型分布20例;仅有头颈部不适者11例,发作性眩晕者及上肢麻木无力者51例,外伤来诊3例。结论:寰椎后桥为颈椎先天变异诱发眩晕重要病因,在临床工作中应引起足够的重视。

Objective：X-ray films of 65 cases were analyzed so as to strengthen value of imageological diagnosis. Methods：X-ray films of 65 cases of posterior bridge of the atlas were collected in our hospital from July in 2014 to September in2016. This retrospective selection on July 4,2014 to September 9,201. The causes were inferred from radiological feature and age composition in simple posterior bridge. The relationship between posterior bridge of the atlas and clinical symptoms was analyzed. Results：In 65 cases,20 cases with simple posterior bridge,25 cases combined with degeneration,20 cases combined with cervical spondylosis.In clinical symotoms,11 cases with head-neck discomfort,51 cases with paroxysmal vertigo and numbness,weakness of upper limb.3 cases went to hospital because of trauma. Conclusion：The posterior bridge of the atlas is an important cause of paroxysmal vertigo induced by congenital variation of cervical verlebr. We should pay enough attention to it in clinic.
