Abstract
A spinal implant is inserted between adjacent vertebrae to function as an disk prosthesis. The prosthesis has two plates fastened to adjacent vertebrae facing each other. The facing sides of the plates each have a depending skirt formed as concentric arcs of about 90 degrees. The skirts are either bowed or tapered in the axial direction. A protrusion is centrally located between the arcs on one plate and a depression is centrally located between the arcs of the other plate. The plates are oriented to each other with the concentric arcs of each interrupted skirt at 90 degrees and the protrusion is engaged in the depression. The plates are then rotated about 90 degrees and the opposed arcs of one plate interlock with the opposed arcs of the other plate to prevent separation in the axial direction.
