Abstract

A dynamic spinal stabilization bone anchor supports the spine while preserving spinal motion. The dynamic bone anchor includes a deflectable post connected by a ball-joint to a threaded anchor. Deflection of the deflectable post is controlled by a centering spring or axial spring. The dynamic bone anchor may be used as a component of a dynamic stabilization system. The dynamic bone anchor provides load sharing while preserving range of motion and reducing stress exerted upon the bone anchors and spinal anatomy.
