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. Structure is provided that affords resistance to shear force applied to the shock absorbing portion. The prosthesis adheres initially mechanically to the vertebral bodies and adheres through arthrodesis over a period of time.
