Abstract
The present invention relates generally to a prosthetic spinal disc for replacing a damaged disc between two vertebrae of a spine. The present invention also relates to a method for implanting a prosthetic spinal disc via posterior or posterior lateral implantation. Other surgical approaches for implanting the prosthetic disc may also be used. The present invention also involves a method for implanting the prosthetic spinal disc while either avoiding or minimizing contact with the spinal cord and nerve rootlets, or reducing the time and extent that they need to be repositioned during implantation.
