Part of the Translational Medicine Research book series (TRAMERE)


This chapter aims to measure linear and angular parameters of the atlas and axis in the Chinese population and provide a morphological basis for the design of the novel posterior atlantoaxial fixator. Thirty-five sets of normal adult dry atlas and axis vertebral samples and 40 sets of normal adult CT images of the upper cervical spine were measured. The parameters include posterior atlantal arch width, height, length, inside semi-diameter, outside semi-diameter, the transarticular screw path length, and the transarticular screw path angle in the transverse plane and in the sagittal plane.
