Abstract

The present disclosure relates to an internal fixation device including an interface portion, a polymer material coupled to the interface portion, wherein the polymer material includes at least one feature on a surface of the polymer material, and means for allowing adequate expansion of the polymer material on each side of the bone fracture site. A method of fixating the internal fixation device to a bone and other internal fixation devices and methods for fixating are also disclosed.

Claims

1. An internal fixation device for use in conjunction with a bone fracture site in a mammal, the internal fixation device comprising:

an interface portion and a polymer material coupled to the interface portion, wherein the polymer material includes at least one feature on a surface of the polymer material; and

means for allowing adequate expansion of the polymer material on each side of the bone fracture site.

2. The internal fixation device of claim 1 wherein the polymer material includes multiple features.

3. The internal fixation device of claim 1 wherein the at least one feature includes particulate material.

4. The internal fixation device of claim 3 wherein the particulate material includes a ceramic material.

5. The internal fixation device of claim 1 wherein the at least one feature includes a protrusion.

6. The internal fixation device of claim 5 wherein the protrusion is selected from a group consisting essentially of a metal material, a non-metal material, a polymer material, and combinations thereof.

7. The internal fixation device of claim 1 wherein the polymer material includes shape memory qualities.

8. The internal fixation device of claim 1 wherein the polymer material includes a resorbable or a non-resorbable polymer material.
