颈性眩晕与颈椎不稳的相关性研究

Study on the relationship between cervical vertigo and cervical instability

目的研究颈性眩晕与颈椎不稳的相关性。方法收集门诊就诊的150例颈性眩晕患者,给予每位患者颈椎正侧位及过伸过屈侧位动态X线片检查。根据White测量标准分析影像学结果,测量评估患者颈椎是否失稳以及失稳的类型,分析颈椎退变的特点。结果①80.7%的颈性眩晕患者都存在颈椎不稳。其中C4-C5之间不稳的发生率最大,颈椎过伸和过屈时C4-C5角度位移不稳发生率分别为41.3%和44.6%,上位椎体相对于下位椎体向前和向后水平位移不稳发生率分别为28.9%和20.6%。②无明显颈椎不稳的颈性眩晕患者颈椎项韧带骨化发生率为10.3%,椎间隙狭窄发生率为72.4%,骨质增生发生率为69%。结论颈椎不稳是颈性眩晕的主要发病原因。无明显颈椎不稳的颈性眩晕患者存在潜在的颈椎退变和颈椎不稳以及代偿性增生反应。

Objective To analyze the relationship between Cervical vertigo and Cervical instability.Methods One hundred and fifty Cervical vertigo patients were selected and Cervical anterior,lateral and dynamic X-ray were provided.Cervical instability was classified according to White standard.Cervical degenerative Characteristics were observed.Results①There were 80.7%Cervical vertigo patients who had Cervical instability.Most Cervical vertigo patients had Cervical instable in C4-C5.The occurrence rates of angle instability were 76.9%and 46.3%respectively in hyperextension and hyperflexion position.The occurrence rates of horizontal instability were 28.9%and 20.6%respectively in the position of upper vertebral forward and backward related to lower.②In Cervical stable patients,10.3%had Cervical nuchal ligament Calcification,72.4%had hyperostosis and 69%had hyperplasia.Conclusion①Cervical instability is the main pathogenesis of Cervical vertigo.②There are potential Cervical degenerative Changes,Cervical instability and hyperplasia Compensation in the patients without Cervical instability.
