Abstract
A three dimensional spine fixation system includes a rigid rod spanning the length of spine to be fixed, a plurality of threaded fasteners to be embedded in the spine, and at least two connectors for connecting the rod to the fasteners. The connectors are extremely adaptable to virtually any desired path for the rod, being fixably movable longitudinally, transversely, or angularly relative to the fasteners, as well as rotationally about the fasteners and rotationally about a predetermined axis angled with respect to the fasteners. By properly positioning the connectors and fasteners, the rod can be easily positioned without bending for virtually any anatomy, due to the ability to move the connectors multi-axially and in three dimensions.
