A method for replacing an intervertebral joint in a human comprising the steps of:
- removing a spinal disc from a human spine to provide an intervertebral space defined by a superior vertebra and an inferior vertebra;
- inserting a prosthesis comprising:
- a first disc comprising a first disc periphery, a first disc superior surface and a first disc inferior surface that comprises a first disc mating portion;
- a second disc comprising a second disc periphery, a second disc superior surface that comprises a second disc mating portion that is substantially complementary to the first disc mating portion and a convex inferior surface;
- and a third disc comprising a concave superior surface that substantially complements the convex inferior surface of the second disc, in the intervertebral space;
