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.
Claims20
A spine implant comprising:
- a rod having a first end and a second end;
- said rod having a first load to deflection profile in a first direction;
- and
- said rod having a second load to deflection profile in a second direction.

A spine implant adapted to be fastened to one or more vertebra comprising:
- an about horizontal member when implanted in a mammal and the mammal is about erect;
- and said horizontal member having greater resistance to deflection when the spine is in one of extension and flexion than when the spine in the other of extension and flexion.
A spine implant adapted to be fastened to one or more vertebra comprising:
- an about horizontal member when implanted in a mammal and the mammal is about erect;
- and said horizontal member having greater resistance to deflection when the spine is in one of extension and flexion than when the spine in the other of extension and flexion;
- and
- said member includes a first and a second end;
- said member includes a platform located between the first and second ends;
- and
- wherein with the spine in flexion the platform is about perpendicular to a cranial-caudal axis and with the spine in extension the platform is about perpendicular to the cranial-caudal axis.
