摘要
A spinal prosthesis for insertion bilaterally into an annulotomy hole created laterally in a spinal disc between two abutting vertebrae that is composed of a first elongated member having first threading at one end and an end cap at its other end, a second elongated member having an end cap with a threaded hole fixed to one end of a hollow tube open-ended at its other end. The members are telescoped together with the threading of the first member mated with the threaded hole of the second member and the open end of said hollow tube disengageably engaged with the end cap of the first member for rotation together. A method for bilaterally implanting the members of the prosthesis using a wire, and then telescopically mating them.
