Abstract: A dynamic stabilization system including a flexible bone anchor and methods for assembling a dynamic stabilization assembly which supports the spine while providing for the preservation of spinal motion. The flexible bone anchor includes a flexible post mounted within a bone anchor. Deflection of the flexible post is controlled by a flexible section integrated into the flexible post. A housing encloses the flexible post isolating it from the bone and providing a stable connection point for other elements of the implant. An internal surface within the housing is positioned to limit deflection of the flexible post. The force/deflection properties of the flexible bone anchor are adapted to be configured and/or customized to the anatomy and functional requirements of the patient by changing the properties of the flexible section and housing.

Abstract: A method for strengthening a spinous process comprises positioning a framework over an outer surface of the spinous process, the framework comprising a mesh connected to a frame. Bone filler is distributed over the mesh so that the bone filler contacts the mesh and contacts the spinous process. The bone filler is allowed to cure. A jig is positioned at the spinous process so that a slot through the jig is exposed to a side of the spinous process. A cannula is oriented so that the cannula is receivable in the slot, and insertable into the spinous process through the slot. Bone filler is injected into the spinous process by way of the cannula, with the injection terminating when a desired amount of bone filler has been injected into the spinous process. The cannula is then removed and the bone filler allowed to cure within the vertebra. The above steps can also be accomplished simultaneously or in any order.

Abstract: A dynamic bone anchor for anchoring a spine stabilization assembly which supports the spine while providing for the preservation of spinal motion. 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. Deflection of the deflectable post is controlled by a compliant sleeve. The force/deflection properties of the dynamic bone anchor may be adapted to the anatomy and functional requirements of the patient. When implanted the pivot point for the deflectable post is placed close to the instantaneous center of rotation of the spine. The dynamic bone anchor may be used as a component of a dynamic stabilization system which supports the spine while providing for the preservation of spinal motion.

Abstract: A spine stabilization prosthesis which supports the spine while providing for the preservation of spinal motion. The spine stabilization prosthesis incorporates a bone anchor having a deflectable post and a compound spinal rod which provide for load sharing while preserving range of motion and reducing stress exerted upon the bone anchors and spinal anatomy. The bone anchor includes a deflectable post connected by a ball-joint to a bone screw. The compound spinal rod includes a coupling mounted to the deflectable post and connected by a pivoting joint to a rod. The combined motions of the ball-joint and the pivoting joint support a range of motion of adjacent vertebrae which closely approximates the natural range of motion of the spine.
