Abstract
A spinal implant for insertion between adjacent vertebrae to function as a disc prosthesis. The prosthesis is formed from two plates fastened to adjacent vertebrae facing each other. The facing sides of the plates have a donut shaped cushioning coupler to replicate the displaced disc material. Stabilizing links are positioned along the edge of the plates to prevent over compression of the shaped cushioning coupler in a bending moment. Adjustable mounting brackets are used to secure the implant to the spine.
