Abstract

A method of treating spine disease including the steps of removing at least a portion of a natural facet joint from a vertebral body; implanting an intervertebral disc prosthesis and replacing the portion of the natural facet joint with a facet joint prosthesis. The removed facet portion may be a cephalad or a caudal facet or both. The replacing step may include the step of attaching the facet joint prosthesis to the vertebral body, such as at or near a pedicle and/or spinous process. The invention also provides spinal prostheses to treat spine disease. The spinal prostheses include an intervertebral disc prosthesis and a facet joint prosthesis having artificial facet joint structure adapted and configured to replace a removed portion of the natural facet joint (cephalad, caudal or both).

Claims

1-10. -10. (canceled)

11. Spinal prostheses to treat spine disease comprising:

an intervertebral disc prosthesis; and

a facet joint prosthesis comprising artificial facet joint structure adapted and configured to replace a removed portion of a natural facet joint.

12. The prostheses of claim 11 wherein the artificial facet joint structure comprises a cephalad prosthesis adapted and configured to replace a removed natural cephalad facet.

13. The prostheses of claim 11 wherein the artificial facet joint structure comprises a caudal prosthesis adapted and configured to replace a removed natural caudal facet.

14. The prostheses of claim 11 wherein the artificial facet joint structure comprises a fixation member adapted and configured to attach the facet joint prosthesis to a vertebral body.

16. The prostheses of claim 11 wherein the intervertebral disc prosthesis is adapted for implantation via a posterior approach.

17. The prostheses of claim 11 wherein the intervertebral disc prosthesis is adapted for implantation via a lateral approach.
