颈性眩晕的X线片特点

X-ray behavior of the cervical vertigo

目的分析颈性眩晕的X线片特点,探讨颈性眩晕的发病机理。方法统计2003年5月～2004年3月门诊及住院病例100例,男46例,女54例。年龄33～72岁(平均534岁)。摄X线片采用标准的Borden氏法,将颈曲分为颈曲存在、颈椎变直及颈椎反曲三种类型。使用椎体角度位移(AngularDisplacement,AD)和椎体水平位移(HorizontalDisplacement,HD)这两种方法测量颈椎稳定性。诊断颈椎不稳的标准为AD>11°,HD>35mm。结果颈椎变直及反曲发生率为97%。角度位移不稳率为67%,水平位移不稳率为58%。结论颈椎不稳等是颈性眩晕的基础因素;颈肩部的疼痛是颈性眩晕的诱发因素;交感神经则是将两者结合的关键因素。

Objective:To study the X ray behavior of the cervical vertigo,investigate the mechanism of the disease Method:One hundred cases were studied,46 males,54 females,33～72 years old(averaged 53 4) The X ray of the cervical vertebral were divided into three types:physiologic curvature;straight;reverse curvature Then to measure the stability by angular displacement(AD)and horizontal displacement(HD) When AD>11°,HD>3 5mm,the unstability was diagnozed Result:Straight and reverse curvature rate 97%,AD 67%,HD rate 58% Conclusion:Cervical unstability is the base factor for cervical vertigo The painfulness is the evoke factor,sympathetic nerve is the key factor
