摘要： The invention provides a method of revising an implanted spinal device, such as an implanted arthroplasty device having a cephalad component fixed to a first vertebra and a caudal component fixed to a second vertebra inferior to the first vertebra. The method includes the following steps: removing a portion of a previously implanted spinal arthroplasty device; and attaching a revision component to a remaining portion of the previously implanted spinal arthroplasty device to alter a biomechanical characteristic of the implanted arthroplasty device. Another aspect of the invention provides a method of limiting motion between adjacent vertebrae including the steps of accessing an implanted spinal arthroplasty device comprising a cephalad component fixed to a first vertebra and a caudal component fixed to a second vertebra inferior to the first vertebra, the cephalad and caudal components having a range of motion between them, and attaching a revision component to the cephalad and caudal components to reduce the range of motion. The invention also includes revision devices for revising the biomechanics of implanted spinal arthroplasty devices.

摘要： 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.

摘要： An implantable endoprosthesis is adapted to articulate with one or more prosthesis surfaces, and is at least partially formed from a material having high wear resistance, which may be a polymeric material such as ultra-high molecular weight polyethylene (UHMWPE), polyetherether ketone (PEEK), and the like, or a metallic material, such as a cobalt-chrome alloy, or a ceramic material, such as alumina or zirconia. The body member of the endoprosthesis may be formed from a composite material, and includes at least a first component formed from a first material having increased wear resistance as compared to that of a second material forming a second component of the body member. The second material is generally more resilient as compared to the first material.
