摘要

An intervertebral disk prosthesis (4), comprising: a rigid top plate (5); a rigid bottom plate (6); and an elastically-compressible intermediate cushion (7) received between the two inside surfaces of the plates (5, 6); remarkable in that the assembly is subdivided in the thickness direction into two units resting one on the other via complementary contact surfaces.
