Hybrid plate system and method

1. A bone plate system comprising:

a bone plate having at least one plate hole formed therein;

at least one pin having a head and a shaft, said head including a plurality of discrete annular concentric ridges, said at least one pin adapted to be disposed in said at least one plate hole; and

a polymer component disposed at least between said at least one pin and said bone plate;

wherein said polymer component is made at least in part of a polymer that may be melted through the application of ultrasonic energy.

2. The bone plate system of claim 1 wherein said at least one pin comprises a material that will not be melted through the application of said ultrasonic energy.

3. The bone plate system of claim 2 wherein said material comprises a polymer.

4. The bone plate system of claim 2 wherein said material comprises a metal.

5. The bone plate system of claim 1 wherein said polymer component comprises a coating applied to said head.

6. The bone plate system of claim 1 wherein said polymer component comprises a coating applied to said shaft.

7. The bone plate system of claim 1 wherein said polymer component comprises an insert disposed about said head.

8. The bone plate system of claim 7 wherein said insert has an exterior surface configured to be substantially similar in shape to an exterior surface of said head.

9. The bone plate system of claim 1 wherein said polymer component is constructed to bond said at least one pin to said bone plate.

10. The bone plate system of claim 1 wherein said at least one plate hole includes a series of concentric ridges adjacent to one another.

11. The bone plate system of claim 1 wherein said at least one plate hole and said head each includes tapered surfaces such that said at least one plate hole substantially mates with said head, and said polymer component is disposed between said tapered surfaces of said at least one plate hole and said head.

12. The bone plate system of claim 1 wherein said shaft is threaded.

13. The bone plate system of claim 1 wherein said head further includes a projection disposed opposite said shaft, said projection being configured to mate with an implantation tool.

14. The bone plate system of claim 1 wherein said bone plate and said at least one pin comprise biocompatible metals.

15. The bone plate system of claim 1 wherein said at least one pin comprises a biocompatible ceramic.

16. The bone plate system of claim 1 wherein said at least one plate hole includes a lateral groove.

17. The bone plate system of claim 1 wherein said head includes a lateral groove.

18. The bone plate system of claim 1 wherein said at least one pin comprises a self-tapping screw.

19. A method of implanting a bone plate system comprising the steps of:

positioning a bone plate adjacent to a fracture in a bone, said bone plate having at least one plate hole formed therein;

inserting a pin through said at least one plate hole and into a hole in the bone;

providing a polymer component between at least said pin and said bone plate;

melting said polymer component through the application of energy; and

allowing said polymer component to re-solidify such that a bond is formed between said bone plate and said pin.

20. The method of claim 19 wherein said melting step includes the application of ultrasonic energy.

21. The method of claim 20 wherein said inserting step includes the use of a driving force applied to said pin.

22. The method of claim 19 including pre-drilling said hole in the bone using a guide.

23. The method of claim 22 including pre-drilling said hole in the bone using said bone plate as said guide.

24. The method of claim 19 wherein said pin comprises a self-tapping screw.
