Abstract

An implantable prosthesis system including a selectively applied bone growth promoting agent is disclosed. The types of prostheses which may include a selectively applied bone growth promoting agent include rods, fracture plates, screws, as well as other types of prostheses. Additionally, the structural composition of many types of prostheses may be modified to help induce bone ingrowth and allow for fusion with the implantable prosthesis.

Claims

1. An implantable prosthesis system, comprising:

a fracture plate configured to be attached to a bone;

the fracture plate including a first portion and a second portion along a lower surface; and

wherein a bone growth promoting agent is selectively applied to the first portion of the lower surface.

2. The implantable prosthesis system according to claim 1, wherein the fracture plate includes holes.

3. The implantable prosthesis system according to claim 2, wherein the fracture plate includes a third portion.

4. The implantable prosthesis system according to claim 3, wherein the bone growth promoting agent is selectively applied to the first and the third portions.

5. The implantable prosthesis system according to claim 1, wherein the bone growth promoting agent is disposed in a pattern selected from the group consisting essentially of striped patterns, spotted patterns, diagonal patterns geometric patterns, shapes, and any combination thereof.

6. The implantable prosthesis system according to claim 1, wherein the fracture plate includes at least one hole configured to receive a screw.

7. The implantable prosthesis system according to claim 6, wherein the fracture plate includes two holes, each hole being configured to receive a screw.

8. The implantable prosthesis system according to claim 6, wherein the fracture plate includes more than two holes.

9. An implantable prosthesis system, comprising:

a fracture plate configured to be attached to a bone;

the fracture plate including a recess configured to receive a liner;

the liner including a first portion and a second portion along a lower surface configured to contact the bone; and

wherein a bone growth promoting agent is selectively applied to the first portion of the lower surface.

10. The implantable prosthesis system according to claim 9, wherein the depth of the recess is approximately equal to the thickness of the liner.

11. The implantable prosthesis system according to claim 9, wherein the liner is a wafer of bone.

12. The implantable prosthesis system according to claim 9, wherein the liner is attached to the fracture plate with an attachment selected from the group consisting essentially of an adhesive, hooks, microscopic hooks, temperature difference, interference fit, a Morris taper, and magnetic features.

13. The implantable prosthesis system according to claim 9, wherein the bone growth promoting agent is disposed in a pattern selected from the group consisting essentially of striped patterns, spotted patterns, diagonal patterns, geometric patterns, shapes, and any combination thereof.

14. An implantable prosthesis system, comprising:

a fracture plate including at least one hole disposed along a lower surface;

the lower surface including a first region and a second region; and

wherein a bone growth promoting agent is selectively applied to the first region and at least one hole.

15. The implantable prosthesis system according to claim 14, wherein the fracture plate includes many holes.

16. The implantable prosthesis system according to claim 15, wherein the holes are disposed along the entirety of the lower surface.

17. The implantable prosthesis system according to claim 14, wherein the holes include a bone growth promoting agent.

18. The implantable prosthesis system according to claim 14, wherein the holes are configured to contact a tissue adjacent to the bone.
