A disc replacement prosthesis is described which is placed within the intradiscal space vacated by a removed deteriorated disc, and which affords mobility rather than fusion between adjacent vertebral bodies. The prosthesis also protects remaining discs from deterioration by providing a shock absorbing prosthesis portion. It adheres initially mechanically to the vertebral bodies and adheres through arthrodesis over a period of time.
