颈椎曲度和活动度的X线指数法分析

目的：探索一种测量颈椎曲度和活动度的新方法以及分析颈椎退变的放射学特征。方法：设计并应用了X线指数法，在78名颈椎病、90名颈部症状患者和86名正常人的颈椎动态侧位片上，分析颈椎曲度和最大屈伸活动度。结果：颈椎病组和症状组的颈椎前凸均减小，但前者更明显；颈椎病组的颈椎最大活动度显著减小。结论：X线指数法是一种有效评估颈椎曲度、活动度的新方法，颈椎退变过程中症状出现、生理曲度和最大活动度的改变具有一定顺。

Radiographic Index Analysis of the Cervical Spine Curvature and the Range of Flexion-extension

Objective To provide a new method for measuring cervical spine curvature and the range of flexion-extension and to analyse the radiographic features of the cervical degeneration.Methods The study included 78 patients with cervical spondylosis,90 patients with neck symptoms and 86 normal volunteers.The three groups were compared with each other by the indexes of the cervical spine curvature and the range of flexion-extension.Results There was significantly difference among three groups in the cervical vertebrae lordosis at neutral position.The range of flexion-extension of cervical spondylosis in the patients was smaller than that of the normal volunteers.Conclusions The index method can accurately depict the cervical spine curvature and the range of flexion-extension.There is definitive order in symptom appearance,alterations of physiologic curvature and flexion-extension in the cervical degeneration.
