PROSTHESIS OF IMPERFINABLE IMPLANTABLE BRAVERAL INTERVERTEBRAL DISC

摘要

Intervertebral disk prosthesis (1) formed of at least one means (10) constituting half of the prosthesis, each means comprising: a central means (100) which is a block of viscoelastic material Mv whose mechanical characteristics , in particular the stiffness and the damping are very close to that of a healthy intervertebral disc. means (101a and b) which enclose the means (100) and which are made of metallic materials, or in any other material rigid body compatible with the human body, the assembly of the preceding means (101a and b) with the means (100) being obtained by molding or injection of the material Mv, in orifices or cavities or growths having forms suitable for retention, the said orifices or excrescences being located on certain parts of the means 101 a or b which enclose the means 100
