Abstract:
1. A method of placing a spinal disc prosthesis including two solid prosthesis elements between adjacent spinal vertebrae comprising the steps of: (a) forming an enlarged partially circular space from the back and to one side of the space between adjacent vertebrae previously occupied by a degenerated disc; (b) forming additional spaces within the interiors of the adjacent vertebrae, each of said additional spaces intersecting said enlarged partially circular space and including an upper surface adjacent to said enlarged partially circular space; (c) injecting a liquid or slurry material into said enlarged partially circular space and said additional spaces and causing or allowing said material to harden therein to produce a solid prosthesis element whereby said upper surfaces of said additional spaces prevent said prosthesis element from coming out of said additional spaces; and (d) repeating steps (a), (b) and (c) from the back and to the other side of the space between adjacent vertebrae.
