Abstract
A dynamic spinal stabilization component which supports the spine while providing for the preservation of spinal motion. The component may be integrated in a bone anchor for implantation in a bone of the spine. The component and bone anchor provide load sharing while preserving range of motion and reducing stress exerted upon the bone anchors and spinal anatomy. The dynamic spinal stabilization component includes a deflectable post connected by a ball-joint to a threaded anchor. Deflection of the deflectable post is controlled by an axially compressible spring. The force/deflection properties of the dynamic bone anchor may be adapted to the anatomy and functional requirements of the patient. The dynamic spinal stabilization component may be used as a component of a dynamic stabilization system which supports the spine while providing for the preservation of spinal motion.
