Abstract
The present disclosure provides pedicle-based facet fixation systems and methods. The pedicle-based construct utilized includes a pedicle screw, pedicle anchor, or the like that is selectively secured to a pedicle of a spine of a patient. The pedicle-based construct is selectively coupled to one end of a rod or other elongate member. The other end of the rod or other elongate member is selectively coupled to a clamping mechanism. This clamping mechanism is selectively secured to a facet joint of the spine of the patient, engaging one or both of the associated superior facet and inferior facet. In operation, the pedicle-based construct, rod or other elongate member, and clamping mechanism securely grasp and compress the facet joint, thereby fixing it.
