Abstract
In a spinal stabilization system a facet fixation device is interconnected to an anchor or fixation device driven into a portion of the spine. The facet fixation device has a proximal head and a distal fastener providing compression across a facet joint. A rigid or elastic member interconnects the proximal head of the facet fixation device to the anchor or fixation device, facilitating static or dynamic stabilization. The facet fixation device may extend directly across the facet joint, or a translaminar or laminar transverse process facet (LTPF) fixation device may be used. In the preferred embodiment the facet fixation device includes a distal tip which is self-cutting and tapping. The anchor may be a pedicle screw. The fixation device itself be a facet fixation device, and the facet fixation device may be connected to the anchor or fixation through two members joined with a coupling unit.
