Abstract

A bone plating system includes an external fixation plate fabricated from bone and/or other remodelable materials(s).

Claims

1. A bone plating system which comprises an external fixation plate fabricated from one or more materials capable of remodeling with a mammalian recipient'"'"'s bone such that the fixation plate will initially unite and/or immobilize recipient'"'"'s bone and ultimately be remodeled and incorporated permanently at the fixation site.

2. The bone plating system of claim 1 wherein the bone plate is fabricated in whole or in part from autograft, allograft, xenograft, cortical, cancellous or corticocancellous bone.

3. The bone plating system of claim 2, made from human cortical bone.

4. The bone plating system of claim 2, made from xenograft cortical bone.

5. The bone plating system of claim 1, wherein the bone is made from fully mineralized to partially demineralized bone.

6. The bone plating system of claim 1 wherein the fixation plate is substantially planar.

7. The bone plating system of claim 1, wherein the external fixation plate is attached to the site of fixation with a screw made from bone and/or other remodelable material.

8. The bone plating system of claim 7 wherein the other remodelable material is a ceramic, polymer, bone composite or non-bone composite.

9. The bone plating system of claim 1, where several external fixation plates are joined together to provide a desired configuration.

10. The bone plating system of claim 1, where the external fixation plate is configured and fitted to a specific architecture for surgical implantation.

11. The bone plating system of claim 1, wherein the external fixation plate is incorporated into the renewed bone structure of the living bone which is united or immobilized and such bone growth replaces or eliminates the graft material.

12. The bone plating system of claim 1, wherein the external fixation plate is attached to the exterior surface of the bone.

13. The bone plating system of claim 1, wherein the external fixation plate includes a plurality of projections and/or recesses to facilitate attachment to a plurality of different body portions.

14. The bone plating system of claim 1, wherein the external fixation plate accepts a bone screw or other fixation device for attachment to the bone to be united or immobilized.

15. The bone plating system of claim 5, wherein only portions of the bone plate are partially demineralized to impart flexibility to the external fixation plate.

16. The bone plating system of claim 1 adapted to unite or immobilize more then one bone or portions of a single bone.

17. The bone plating system of claim 1 configured to unite or immobilize vertebral segments.

18. A method for the external fixation of bone which comprises affixing to a desired site of bone requiring fixation the bone plating system of claim 1.

19. The method of claim 18 wherein the bone plating system is inserted into a preformed recess within the bone requiring fixation.

20. The method of claim 18 in which the bone plating system is combined with one or more other bone plates and/or osteoimplants to provide a desired implant architecture.
