Measurement of vertebral rotation from frontal X-ray projections of the pedicles was introduced by Nash and Moe. By the introduction of a vertebral model, their method and different modifications can be described and characterized easily. A geometrical analysis shows, that two parameters are sufficient for this model. When applying an appropriate interpretation of vertebral rotation, rotation measurement can be performed independent of lateral tilting and forward-backward inclination. As a test of the Nash-Moe method 65 vertebrae are each investigated from 15 directions. The measurements are analyzed for each pedicle separately and also compared to the opposite pedicle of the particular vertebra. The results indicate figures for the accuracy of the Nash-Moe method and its modifications for absolute and relative measurements. A simple correction to the Nash-Moe method is proposed.
椎弓根额状位X线投影测量椎体旋转是由纳什和莫伊提出的。通过引入椎体模型，可以轻松描述和表征他们的方法及不同的改进方法。几何分析表明，该模型只需两个参数。当对椎体旋转进行适当解释时，旋转测量可以独立于侧方倾斜和前后倾斜进行。作为对纳什-莫伊方法的测试，对65个椎体从15个方向分别进行研究。对每个椎弓根的测量分别进行分析，并与特定椎体的对侧椎弓根进行比较。结果给出了纳什-莫伊方法及其改进方法在绝对和相对测量方面的准确性数据。提出了对纳什-莫伊方法的一种简单修正。
