[Palmer-Sandberg-Gutmann chiropractic diagnosis of the atlanto-occipital joint from the conventional medical and radiologic viewpoints]

There can be no lateral displacement of the atlas (massae laterales) in relation to the condyles, because this is impossible from an anatomical point of view, neither "angular" (atlas A rule) nor "non-angular" (atlas B rule) in the sense of the "hole-in-one (HIO)" diagnostic method evolved by the U.S. chiropractor Palmer. The course of the condyle baseline is not altered by a lateral displacement of the atlas in relation to the condyles, but by a tilting rotation of the condyles in respect of the atlas. Rotatory movements will result, among other phenomena, in a change of the course of the condyle and atlas baseline due to projection-produced changes in the region of the atlanto-occipital and atlas-axis joints. Last but not least, the course of the condyle and atlas baseline is also influenced by other functional parameters, another important parameter being an asymmetrically constructed joint.
