Abstract
A dynamic spinal implant utilizes cartilage bearing graft material in dynamic disc replacement and/or facet arthroplasty. Methods and apparatus for dynamic spinal implants incorporate bulk articular graft tissues derived from donor joint sources in human (allograft or autograft) or non-human (xenograft) tissue. The donor joint is preferably prepared as a biological dynamic spinal implant with articular cartilage as a bearing interface between adjacent bone surfaces that naturally articulate with respect to one another.
