A dynamic spine 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 to a
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, provides
load sharing while preserving
range of motion and reducing stress exerted upon the bone anchor and
spinal anatomy.
