Abstract

A biocompatible and pliable surgical implant for use in repair and rigid fixation of bone fractures and to compensate for a volume loss is disclosed. The implant includes a biocompatible base member and a volume member having a predetermined volume affixed to the metallic base member. The base is adapted to be secured proximate the fractured bone area.

Claims

1. An implant, comprising:

(a) a base member that provides structural support to a bone structure when the base member is placed on the bone structure; and

(b) a volume member affixed to the base member to provide a predetermined volume over the base member.

2. The implant of claim 1 wherein the volume member is affixed on a topside of the base member.

3. The implant of claim 1 wherein the base member is made from a metallic material and has at least one extension that is adapted to be secured to the bone structure.

4. The implant of claim 3 wherein the base member includes a plurality of perforations.

5. The implant of claim 1 wherein the base member is made from titanium.

6. The implant of claim 1 wherein the volume member is relatively porous and is made from one of (i) polyurethane, and (ii) a synthetic material.

7. The implant of claim 1 wherein the volume member is secured to the base member by a biocompatible material.

8. The implant of claim 1 wherein the base member and the volume members are fused together.

9. The implant of claim 1 wherein the base member is pliable and biocompatible.

10. The implant of claim 1 wherein at least a portion of the volume member is greater in thickness than the base member.

11. The implant of claim 1 wherein the base member is made from one of (i) a wire mesh, (ii) pure titanium, (iii) stainless steel, (iv) Teflon, (v) tantalum, (vi) vitallium, (vii) supramid and (viii) a combination of metallic and nonmetallic materials.

12. The implant of claim 1 wherein the volume member is biocompatible.

18. The implant of claim 1 wherein the volume member is attached to the base member by one of (i) an adhesive;

(ii) a heating method;

(iii) an electrochemical process; and

(iv) a bonding agent that dissolves into a human body.

13. A method of making an implant, comprising:

(a) providing a base member having sufficient strength to provide structural support to a fractured bone structure when placed on an area of the fractured bone structure; and

(b) attaching a volume member on a surface of the base member to provide a predetermined volume that compensates for a tissue volume loss when the implant is implanted on a bone structure.

14. The method of claim 13 further comprising, shaping the implant to be compliant with a bone structure.

15. The method of claim 13 wherein attaching the base member to the volume member includes attaching by one of (i) an adhesive;

(ii) a fusion process;

(iii) a bonding process;

(iv) a heating method;

(v) an electrochemical process; and

(vi) a bonding agent that dissolves after the implant has been implanted.

16. The method of claim 13 wherein the base member is made from a metallic material and includes a plurality of perforations and at least one attachment member adapted to be secured to the bone structure by a bone screw.

17. The method of claim 13 wherein the volume member is greater in thickness than the base member.
