Abstract:

Objective To study the morphology of the atlas articular surface.  Methods The atlas articular surfaces were measured and classified in 125 atlases. The measurement projects included the major axis, minor axis, depth and the angle of the anterior posterior arch’ nodular connection. Results The form of the atlas articular surface could be divided into the following 4 types: both sides being elliptical, both sides being dumbbell-like, the left side being elliptical and the right-side being dumbbell-like, and the left side being dumbbell-like and right-side being elliptical. There were statistical differences in morphological data of each articular surface. Conclusion There are statistical morphological differences on the lateral mass of the atlas articular surface.
