The locations of the instantaneous axes of rotation for the cervical motion segments C2-3 to C6-7 were determined from flexion-extension radiographs of 40 normal subjects using a modified overlay technique. The biological variation of the instantaneous axes of rotation was small, as was the technical error associated with the technique used. The data obtained enabled the formal definition of the normal range of locations for the instantaneous axes of rotation of the typical cervical motion segments.
采用改良叠加技术，根据40名正常受试者的屈伸位X线片，确定了C2-3至C6-7颈椎运动节段瞬时旋转轴的位置。瞬时旋转轴的生物学变异较小，与所使用技术相关的技术误差也较小。所获得的数据使得能够正式定义典型颈椎运动节段瞬时旋转轴位置的正常范围。
