Abstract
An adaptable spinal facet joint prosthesis may include a pedicle fixation element; a laminar fixation element; and a facet joint bearing surface having a location adaptable with respect at least one of the pedicle fixation element and the laminar fixation element. Methods of implanting an adaptable spinal facet joint prosthesis may include determining a desired position for a facet joint bearing surface; and attaching a prosthesis comprising a facet joint bearing surface to a pedicle portion of a vertebra and a lamina portion of a vertebra to place the facet joint bearing surface in the desired position. A facet joint prosthesis implant tool may include a tool guide adapted to guide a vertebra cutting tool; and first and second fixation hole alignment elements extending from the saw guide. Systems for treating spinal pathologies may include intervertebral discs in combination with spinal and facet joint prostheses.
