<p>An improved pedicle screw system is provided with an offset stabilizer rod for the internal fixation of the spine. The pedicle screw system includes at least two multi-angle pedicle screw units adapted for anchored securement to patient bone, and an elongated stabilizer rod extending therebetween. Each pedicle screw unit includes a bone screw associated with an anchor bracket defining a laterally offset and upwardly open channel or trough for receiving and supporting the stabilizer rod. A securement member such as a set screw is fastened to the anchor bracket for compressively retaining the stabilizer rod within the bracket channel or trough. The securement member may also bear against the associated bone screw for compressively retaining the screw in position relative to the anchor bracket.</p> |
