Abstract
A dynamic spinal stabilization component suitable for use in stabilizing of the spine. The component is selectably attachable to a bone anchor for implantation in a bone of the spine. The dynamic spinal stabilization component includes a deflectable post connectable by a joint to bone anchor. Deflection of the deflectable post is controlled by a compliant member. The force/deflection properties of the deflectable post may be adapted to the functional requirements and anatomy of the patient. The dynamic spinal stabilization component, when secured to a bone anchor, provide load sharing while preserving range of motion and reducing stress exerted upon the bone anchors and spinal anatomy.
