Abstract

A blank used for machining customized prosthetic components is provided which includes a prefabricated seating surface, normally shaped as an anti-rotation device, used to seat the component in the corresponding implanted, or natural, surface in the patient's body. Prosthetic components need to be custom manufactured because each patient presents a different need, however, the standardized shape of seating surfaces allows for these to be machined in large scale, without affecting the quality of the treatment the patient receives. Once the customized manufacturing has been completed around the seating surface, the part requires no further machining and is ready to be used.

Claims (37)

1. A blank from which a prosthetic component can be formed, comprising:

a blank body made from a biocompatible material;

the blank body having a component portion including at least three surfaces and a support portion connected to one of the at least three surfaces of the component portion;

an unconnected surface of the component portion forming a pre-fabricated seating surface, the pre-fabricated seating surface including at least one anti-rotation element; and

at least one access path for receiving a fastening screw.

2. The blank of claim 1 wherein the biocompatible material is Titanium.

3. The blank of claim 1 wherein the biocompatible material is a ceramic material.

4. The blank of claim 1 wherein the biocompatible material is a biomaterial.

5. The blank of to claim 1 wherein the at least one anti-rotation element is hexagonal in shape.

6. The blank of claim 1 wherein the at least one anti-rotation element is shaped as a Morse-Cone.

7. The blank of claim 1 , wherein the support portion is attached to the component portion by a chemical compound.

8. The blank of claim 7 , wherein the component portion includes a top surface, a bottom surface, and a multi-sided surface.

9. The blank of claim 8 , wherein the at least one pre-fabricated seating surface is the top surface.

10. The blank of claim 8 , wherein the at least one pre-fabricated seating surface is the bottom surface.

11. The blank of claim 8 , wherein the at least one pre-fabricated seating surface is a side of the multi-sided surface.

12. The blank of claim 1 , wherein the chemical compound is a cement.

13. The blank of claim 1 , wherein the component portion includes a top surface, a bottom surface, and a cylindrical surface.

14. The blank of claim 13 , wherein the at least one pre-fabricated seating surface is the top surface.

15. The blank of claim 13 , wherein the at least one pre-fabricated seating surface is the bottom surface.

16. The blank of claim 13 , wherein the at least one pre-fabricated seating surface is the cylindrical surface.

17. A blank from which a prosthetic component can be formed, comprising:

a blank body having a first support portion and a second component portion, wherein the first and second portions are integrally formed from a single piece of material and positioned adjacent one another, the blank body being made from a biocompatible material;

a portion of an outer surface of the blank body forming a pre-fabricated seating surface, the pre-fabricated seating surface including at least one anti-rotation element; and

at least one access path configured to receive a fastening screw for securing the prosthetic component.

18. The blank of claim 17 , wherein the blank body includes a top outer surface, a bottom outer surface, and a cylindrical outer surface.

19. The blank of claim 18 , wherein the at least one pre-fabricated seating surface is the top outer surface.

20. The blank of claim 18 , wherein the at least one pre-fabricated seating surface is the bottom outer surface.

21. The blank of claim 18 , wherein the at least one pre-fabricated seating surface is the cylindrical outer surface.

22. The blank of claim 17 , wherein the blank body includes a top outer surface, a bottom outer surface, and a multi-sided outer surface.

23. The blank of claim 22 , wherein the at least one pre-fabricated seating surface is the top outer surface.

24. The blank of claim 22 , wherein the at least one pre-fabricated seating surface is the bottom outer surface.

25. The blank of claim 22 , wherein the at least one pre-fabricated seating surface is one of the sides of the multi-sided outer surface.

26. The blank of claim 17 , wherein the biocompatible material is Titanium.

27. The blank of claim 17 , wherein the biocompatible material is a ceramic material.

28. The blank of claim 17 , wherein the biocompatible material is a biomaterial.

29. The blank of claim 17 , wherein the at least one anti-rotation element is hexagonal in shape.

30. The blank of claim 17 , wherein the at least anti-rotation element is a shaped as a Morse-Cone.
