Abstract
A vertebral prosthesis and spinal fixation system includes a vertebral prosthesis having a height adjustable shaft and an anchoring mechanism coupled to the shaft. The system further includes a spinal fixation device and a number of bone screws. The bone screws attach the fixation device to the vertebral prosthesis via the anchoring mechanism.
Claims20
A spinal implant system suitable for a spinal fusion procedure, comprising:
- a vertebral prosthesis adapted to be placed at the site of an excised vertebra between two adjacent remaining vertebrae, the vertebral prosthesis comprising:
- a shaft having a first end and a second end;
- a first end plate coupled to the first end of the shaft, the first end plate having an outer edge defining an outer perimeter of the first end plate;
- and
- a first anchor extending from the first end plate such that the first anchor is positioned within the outer perimeter of the first end plate, the first anchor defining an aperture configured to receive a bone screw.

A method of implanting a vertebral prosthesis, comprising:
- opening an aperture in a patient to permit access to a first vertebra located adjacent to a second vertebra;
- removing at least a portion of the first vertebra;
- providing a vertebral prosthesis;
- inserting the vertebral prosthesis into the space created by the removal of the portion of the first vertebra;
- providing a bone screw;
- providing a spinal fixation device;
- coupling the spinal fixation device to the prosthesis with the bone screw, wherein the bone screw extends through at least a portion of the second vertebra;
- and
- closing the aperture.
