Abstract
An intervertebral disk 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 plates comprises at least one stud for stressing the body along a direction not parallel to a main access of the prosthesis and mobile relative to the body. Thus the prosthesis imitates and approximates the mechanical properties of a healthy natural intervertebral disk.
