Abstract
A method and apparatus of limiting at least one degree of movement between a superior vertebral body, an inferior vertebral body, and an intermediate vertebral body that is disposed between the superior and inferior vertebral bodies of a patient. The method can comprise: advancing a distal end of a stabilization device into a pedicle of the intermediate vertebral body; positioning a proximal portion of the stabilization device such that the proximal portion limits at least one degree of movement between the superior vertebral body and the intermediate vertebral body by contacting a surface of the superior vertebral body; and advancing a distal end of a fixation device into a facet of the intermediate vertebral body and into a facet or pedicle of the inferior vertebral body for stabilizing the intermediate vertebral body and the inferior vertebral body.
