Abstract

A versatile dynamic bone anchor and spinal rod for use in a dynamic stabilization system to support the spine while providing for the preservation of spinal motion. The dynamic bone anchor provides load sharing while preserving range of 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 compliant member. The dynamic rod is connected to the dynamic bone anchor by a joint which permits relative movement of the deflectable post and rod reducing the stress exerted upon the bone anchors and spinal anatomy.
