Beschreibung
Zusammenfassung:	An adaptable spinal facet joint prosthesis, including 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. The invention also includes a method of implanting an adaptable spinal facet joint prosthesis including the steps of 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. The invention also provides a facet joint prosthesis implant tool including a tool guide adapted to guide a vertebra cutting tool; and first and second fixation hole alignment elements extending from the saw guide. The invention also provides systems for treating spinal pathologies that include intervertebral discs in combination with spinal and facet joint prostheses.
