Abstract

A biocompatible metal piece intended for stabilizing vertebral bodies in cervical, thoracic and lumbar regions. This piece remarkably diminishes the profile, weigh and volume of an implant; the compatibility of the curving digitalized surfaces allow to immobilize vertebral bodies without internal efforts, achieving an important diminishing of time during the implant installation.

Claims

1. An apparatus with digitalized surfaces comprising a sole rectangular solid metal bar, rounded on its edges by which surfaces of contact have curves that are generated according to the curves of the transverse apophysis on vertebral parts.

2. The apparatus of claim 1 wherein by producing identical cavities between the digitalized bars and transverse apophysis of the vertebral bodies, the apparatus makes possible that all the efforts may be distributed uniformly in a tridimensional manner.

3. The apparatus of claim 1 further comprising perforations to fix the digitalized pieces to the vertebras, said perforations being located and oriented according to the position of the vertebral pendiculous.

4. The apparatus of claim 1 comprising biocompatible materials which specifically match the surfaces of the transverse apophysis obtained on a functional position from a selected patient.

5. The apparatus of claim 4 wherein the digitalized surfaces of the individual vertebral parts are generated on a solid bar made out of a biocompatible material in such a way that once when the parts are fixed, they become a sole unit.
