Claims
- 1. A modular prosthesis system for replacement of a portion of a bone, said modular prosthesis system comprising:
a stem component having an anchoring portion and a mounting portion; and a head component defining a channel, said channel operable to be rigidly connected to said mounting portion along an assembly axis that is transverse to a longitudinal axis of said stem component, wherein said head component is substantially immovably fixed to said stem component.
- 2. The modular prosthesis system as defined in claim 1 wherein said assembly axis is substantially perpendicular to the longitudinal axis.
- 3. The modular prosthesis system as defined in claim 1 wherein said assembly axis is between about 45 degrees to about 135 degrees relative to the longitudinal axis.
- 4. The modular prosthesis system as defined in claim 1 wherein said assembly axis is about 0 degrees to about 180 degrees relative to the longitudinal axis.
- 5. The modular prosthesis system as defined in claim 1 wherein said stem component is substantially formed as a single piece.
- 6. The modular prosthesis system as defined in claim 1 wherein said head component is formed from a first member and a second member.
- 7. The modular prosthesis system as defined in claim 6 wherein said first member is an outer shell and said second member is an inner core.
- 8. The modular prosthesis system as defined in claim 7 wherein said inner core is formed from a polymeric material and said outer shell is formed of a material selected from a group comprising ceramic, titanium, stainless steel, cobalt chrome, and a combination thereof.
- 9. The modular prosthesis system as defined in claim 1 wherein said head component is formed from at least one of ceramic, titanium, stainless steel, cobalt chrome, and a combination thereof.
- 10. The modular prosthesis system as defined in claim 1 wherein said channel is a substantially elongated rectangular channel.
- 11. The modular prosthesis system as defined in claim 10 wherein said channel is a substantially elongated rectangular T-shaped channel.
- 12. The modular prosthesis system as defined in claim 1 further comprising a locking device operable to lock said head component to said stem component.
- 13. The modular prosthesis system as defined in claim 12 wherein said locking device interacts with said mounting portion and said channel.
- 14. The modular prosthesis system as defined in claim 1 wherein said mounting portion is dove tail-shaped and said channel has a corresponding mating shape.
- 15. The modular prosthesis system as defined in claim 12 wherein said locking device is at an interface between said head component and said mounting portion.
- 16. The modular prosthesis system as defined in claim 15 wherein said locking device includes at least one protuberance.
- 17. A modular prosthesis for replacement of a portion of a bone comprising:
a stem component having an anchoring portion and a mounting portion; a head component defining a channel, said channel operable to be rigidly connected to said mounting portion along an assembly axis that is transverse to a longitudinal axis of said stem component; and a locking device operable to rigidly lock said head component to said stem component.
- 18. The modular prosthesis system as defined in claim 17 wherein said assembly axis is substantially perpendicular to the longitudinal axis.
- 19. The modular prosthesis system as defined in claim 17 wherein said assembly axis is between about 45 degrees to about 135 degrees relative to the longitudinal axis.
- 20. The modular prosthesis system as defined in claim 17 wherein said assembly axis is about 0 degrees to about 180 degrees relative to the longitudinal axis.
- 21. The modular prosthesis system as defined in claim 17 wherein said stem component is substantially formed as a single piece.
- 22. The modular prosthesis system as defined in claim 17 wherein said head component is formed from at least one of ceramic, titanium, stainless steel, cobalt chrome, and a combination thereof.
- 23. The modular prosthesis system as defined in claim 17 wherein said mounting portion is dove tail-shaped and said channel has a corresponding mating shape.
- 24. The modular prosthesis system as defined in claim 17 wherein said channel is a substantially elongated rectangular channel.
- 25. The modular prosthesis system as defined in claim 17 wherein said locking device is formed integral with at least one of said stem component and said head component.
