Abstract
An intervertebral disc prosthesis comprising two plates and a cushion interposed between the plates is contemplated. The cushion includes a compressible body having two ends in contact with the plates. At least one of the ends is freely displaceable relative to the plate in a parallel direction. Thus, the prosthesis imitates and approximates the mechanical properties of a healthy natural intervertebral disc.
