Abstract

An orthopedic prosthesis mold, including a first housing defining a first cavity therein shaped to form a portion of an orthopedic prosthesis; a second housing coupled to the first housing, the second housing defining a second cavity therein shaped to form a portion of an orthopedic prosthesis; and a reinforcement element attached to at least one of the first or second housings, the reinforcement element resisting deformation of the first and second housings. The reinforcement element may include a member exterior to the first and second cavities, the member spanning across a substantial width of the prosthesis mold.

Claims

1. An orthopedic prosthesis mold, comprising:

a first housing defining a first cavity therein shaped to form a portion of an orthopedic prosthesis;

a second housing coupled to the first housing, the second housing defining a second cavity therein shaped to form a portion of an orthopedic prosthesis; and

a reinforcement element attached to at least one of the first or second housings, the reinforcement element resisting deformation of the first and second housings.

2. The orthopedic prosthesis mold of claim 1, wherein the reinforcement element includes a member exterior to the first and second cavities, the member spanning across a substantial width of the prosthesis mold.

3. The orthopedic prosthesis mold of claim 1, further comprising a plurality of reinforcement elements vertically spaced along the prosthesis mold.

4. The orthopedic prosthesis mold of claim 1, wherein the first and second cavities each have a concave shape, and wherein the reinforcement element spans an interior of the concave shape exterior to the first and second cavities.

5. The orthopedic prosthesis mold of claim 1, wherein at least one of the first and second cavities defines an anterior portion and a posterior portion shaped to form a femoral knee joint prosthesis, and wherein the reinforcement element extends between the anterior and posterior portions.

6. The orthopedic prosthesis mold of claim 1, wherein the first housing defines an injection port.

7. The orthopedic prosthesis mold of claim 6, further comprising an injection port cap releasably engageable with the injection port to seal the injection port.

8. The orthopedic prosthesis mold of claim 7, wherein the injection port cap includes an indicia on a surface thereof that is positionable within the first cavity.

9. The orthopedic prosthesis mold of claim 6, wherein the first housing defines a plurality of vent ports.

10. The orthopedic prosthesis mold of claim 9, further comprising a plurality of vent caps positionable to cover the vent ports, wherein at least one vent cap includes a cutting surface.

11. The orthopedic prosthesis mold of claim 1, further comprising a connecting element releasably engageable with the first and second housings, the connecting element preventing separation of the first housing from the second housing.

12. The orthopedic prosthesis mold of claim 11, wherein the connecting element includes a strap circumscribing an exterior of the first and second housings.

13. The orthopedic prosthesis mold of claim 11, wherein the connecting element includes a plurality of releasably engageable portions positionable around an exterior of the first and second housings.

14. The orthopedic prosthesis mold of claim 11, wherein the first and second housings each define a protruding shoulder, and wherein the connecting element defines a recess engageable with the shoulders.

15. An orthopedic prosthesis mold, comprising:

a first housing defining a cavity therein shaped to create a portion of an orthopedic prosthesis;

a second housing defining an injection port and a cavity therein shaped to create a portion of an orthopedic prosthesis, wherein the second housing is at least partially slidably positionable within the first housing; and

a connecting element releasably engageable to an exterior of the first housing, wherein the connecting element is releasably engageable to the second housing at a plurality of positions to prevent separation of the first housing from the second housing.

16. The orthopedic prosthesis mold of claim 15, wherein the second housing includes indicia corresponding to a dimension of a prosthesis.

17. The orthopedic prosthesis mold of claim 15, wherein the connecting element includes a plurality of releasably engageable portions.

18. The orthopedic prosthesis mold of claim 15, wherein the first housing defines an aperture therein, and the connecting element defines a protrusion passable through the aperture to engage the second housing.

19. A method of creating an orthopedic prosthesis, comprising:

providing a first housing having a cavity therein shaped to create a portion of an orthopedic prosthesis and a second housing defining an injection port and a cavity therein shaped to create a portion of an orthopedic prosthesis, wherein the second housing includes a plurality of indicia indicating a plurality of dimensions for an orthopedic prosthesis;

slidably positioning at least a portion of the second housing into the first housing to a preselected position indicated by the indicia;

immovably securing the first housing to the second housing with a connecting element; and

injecting a curable material into the injection port of the second housing.

20. The method of claim 19, wherein the connecting element circumscribes an exterior of the first housing, and engages the second housing through an aperture in the first housing.
