ABSTRACT:
A method of intervertebral disk stabilization in which adjacent vertebrae are spread and a portion of the intervertebral disk is removed from therebetween is disclosed. An elongate, generally cylindrically shaped implant having middle and end portions, the middle portion being of larger diameter than the end portions, is inserted into the space between the adjacent vertebrae from which the disk was removed and then rotated. Threads formed on the outside surface of the implant bear against the bodies of the adjacent vertebrae to move the implant back and forth in an anterior-posterior direction in the disk space to a position in which both the larger diameter middle portion and the smaller diameter end portions of the implant engage the bodies of the adjacent vertebrae to stabilize the adjacent vertebrae relative to each other.
