为什么颈椎病患者要拍X线片?

来源:华人健康网 | 发布时间:2012-03-16 01:17:41 | www.chinesejk.com

颈椎X线片不但可以用来诊断颈椎病,更重要的是可以除外许多其他颈部疾病。如颈椎后纵韧带骨化、类风湿性关节炎、骨关节结核、颈椎先天畸型、骨折脱位和肿瘤等。一般可拍颈椎的正、侧、双斜位片。侧位片可观察椎体排列、关节突、关节位置的微细变化及棘突的移位等,尤其可较准确地测量椎管前后径,并可观察颈椎生理曲度的改变。正位片可显示双侧钩椎关节及其间隙,可观察双侧椎板宽度是否对称,棘突位置是否有移动。在颈1~2开口位,可观察枢椎齿状突的形态及其异常改变。斜位片主要观察椎间孔的形态及钩椎关节骨质增生的程度,颈椎有旋转移位时,可见到患椎的上关节突向前上方变位,使椎间孔横径变小,功能位检查即拍颈椎过伸、过屈体位的侧位片,可显示颈椎由于失稳引起的移位变化。
