Commmplete osseous union took place in dogs between the bodies of the vertebrae, following removal of the intervertebral disc. In young animals the union was more rapid and more likely to be completely osseous.
Complete bony union between the bodies produced sufficient fixation to prevent movement between the articular facets and between the spinous processes. When union was incomplete, there was considerable fixation of bodies, but movement took place between the articular facets.
