Osseous configurations of the axial skeleton: specific application to spatial relationships of vertebrae.

Gerow G.

Traditionally, the chiropractic profession has employed two different methods to describe spatial relationships (i.e., listings) of subluxated vertebrae for corrective orientation purposes. These methods (Palmer- Gonstead - Firth and Diversified), in addition to being somewhat limited in their scope of application, do result in some confusion. This paper, therefore, proposes a new method designating vertebral position and movement based on the "right-handed orthogonal coordinate system" of White, Panjabi and others.
