Abstract
A dynamic stabilization, motion preservation spinal implant system includes an anchor system, a horizontal rod system and a vertical rod system. The systems are modular so that various constructs and configurations can be created and customized to a patient.
Claims24
An implant adapted to be implanted in the spine of a patient comprising:
- a deflection rod system including a deflection rod that has a non-linear deflection to load characteristic.
An implant adapted to be implanted in a spine of a patient comprising:
- a body including a shield with a shield cavity;
- a deflection rod that is mounted in said shield cavity;
- said deflection rod able to be deflected in said shield cavity and the motion of said deflection rod is limited by the shield cavity;
- and
- said deflection rod has a non-linear deflection to load characteristic.
