摘要

The invention concerns an intervertebral disc prosthesis (2; 102) comprising two plates (4; 104) and a deformable body (16; 116) interposed between the plates. At least one of the plates (4; 104) comprises at least a stud (10; 110) for stressing the body along a direction not parallel to a main axis (12; 112) of the prosthesis and mobile relatively to the body (16; 116).
