ABSTRACT:
A versatile dynamic spinal rod and bone anchor assembly for use in a dynamic stabilization system to support the spine while providing for the preservation of spinal motion. Alternative embodiments can be used for spine fusion. The dynamic bone anchor provides load sharing while preserving range of motion and reducing stress exerted upon the bone anchors and spinal anatomy. The dynamic bone anchor includes a deflectable post connected by a ball-joint to a threaded anchor. The dynamic rod connects different levels of the construct in a multilevel construct. 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.
