Abstract
A spinal fixation system comprises a pair of facet screws that extend through the facet joint from the inferior facet of a superior vertebra and into the base of the transverse process of the immediately inferior vertebra. A pair of stabilizing bars are operatively coupled to the screws adjacent their heads. The bars carry fingers that extend in a superior direction and loop over the superior aspect of the pedicle of the superior vertebra. The stabilizing bars thus stabilize the facet screws and prevent their tendency to toggle, thereby conjunctively stabilizing the superior vertebra to the immediately inferior vertebra, for example, to facilitate the healing of a fusion.
