Abstract
A dynamic stabilization, motion preservation spinal implant system includes a deflection rod system implant. The system is modular so that various constructs and configurations can be created and customized to a patient.
Claims20
An implant adapted to be implanted in a spine comprising:
- a deflection rod system including a rod that is deflectable;
- a connector rod that is attached to said deflectable rod with a connector;
- a bone anchor;
- and
- a mount that mounts said deflection rod system relative to said bone anchor in one of a plurality of positions.

An implant adapted to be implanted in a spine comprising:
- a deflection rod system including a rod that is deflectable;
- a connector rod that is attached to said deflection rod with a connector;
- a mount that mounts said deflection rod relative to a bone anchor in one of a plurality of positions;
- and
- wherein said mount includes a curved mount surface and said bone anchor includes a curved anchor surface which is mated with the curved mount surface with the curved mount surface moveable relative to said curved anchor surface.
2 more elements
An implant adapted to be implanted in a spine comprising:
- a deflection rod system including an inner rod and an outer shell and a shield with a shield cavity into which said inner rod and said outer shell are mounted and wherein said inner rod and said outer shell can be deflected in said shield cavity and the shield cavity limits the amount of deflection of said inner rod and said outer shell;
- a connector rod that is attached to said inner rod with a connector;
- a mount that mounts said deflection rod system relative to a bone anchor in one of a plurality of positions;
- wherein said mount includes a curved mount surface and said bone anchor includes a curved anchor surface which is mated with the curved mount surface with the curved mount surface moveable relative to said curved anchor surface;
- wherein said connector is adapted to be mounted in-line with the bone anchor so as to minimize any torque that said connector rod can place on the bone anchor;
- and
- wherein said mount is adapted to mount said deflection rod system about transverse to the bone anchor
4 more elements
The implant of claim 18 wherein said inner rod is comprised of a super elastic material.
