颈椎关节半脱位征像的诊断价值

Diagnostic Value on Sign of Subluxation of Cervical Vertebrae with Radiologic Examimation

目的：探讨颈椎Ｘ线片上半脱位征像的临床诊断意义；方法：对８７例颈痛和２１例无症状患者的颈椎Ｘ线片进行研究，内容包括齿突侧块间距、棘突偏歪和双边征等；结果：绝大多数左右齿突侧块间距不对称，棘突偏歪和双边征较为常见，多见于Ｃ５、Ｃ４和Ｃ６颈椎。两组间所谓颈椎半脱位的发生率相等。结论：对颈椎关节半脱位的提法值得商榷。颈椎关节半脱位的诊断应当有两种，一是单纯的Ｘ线学诊断，二是结合临床体查结果的临床诊断。

Objective:To probe into the relationship between subluxation of cervical vertebrae and clinical implication, and their possible clinical diagnostic value. Methods:In roentgenogram of cervical vertebrae, the distance of odontoid processlateral mass and divergence of the spinous processes and sign of double contour were studied in 87 cases with cervicodynia and 21 asymptomatic cases.Results:The distances of odontoid processlateral mass were asymmetry in most cases, and the divergence of spinous processes and sign of double contour were also common. The variations of cervical vertebrae were seen commonly in C5、 C4 and C6.Conclusions:There is little evidence to support the contention that subluxation of cervical vertebrae is of diagnostic significance.The subluxation should be diveded two kinds, one is purely roentgenological diagnosis, and another is diagnosis that combine roentgenological signs with clinical signs.
