Abstract: A medical implant is disclosed. The medical implant includes: a first biocompatible metal forming a substrate (210, 310, 410), a second biocompatible metal diffused into the first biocompatible metal to form an biocompatible alloy surface (220, 314, 414), the alloy surface further including a diffusion hardening species, wherein the diffusion hardening species may be carbon, nitrogen, oxygen, boron, or any combination thereof. A method of forming a medical implant is also disclosed. The method includes the steps of: providing a first biocompatible metal or alloy that forms a substrate (210, 310, 410), providing a second biocompatible metal or alloy, diffusing the second biocompatible metal into the first biocompatible metal to form an alloy layer (220, 314, 414), removing excess second metal material from the substrate to expose the alloy layer, and diffusion hardening the alloy layer.

Abstract: Porous biocompatible structures suitable for use as medical implants and methods for fabricating such structures are disclosed. The disclosed structures may be fabricated using rapid manufacturing techniques. The disclosed porous structures have a plurality of struts and nodes where no more than two struts intersect one another to form a node. Further, the nodes can be straight, curved, portions that are curved and/or portions that are straight. The struts and nodes can form cells which can be fused or sintered to at least one other cell to form a continuous reticulated structure for improved strength while providing the porosity needed for tissue and cell in-growth.

Abstract: Oxidation resistant crosslinked ultrahigh molecular weight polyethylene (UHMWPE) is described, wherein at least two different additives in the manufacture synergistically increase the oxidation resistance of crosslinked UHMWPE. This allows the manufacture of oxidation resistant crosslinked UHMWPE using lower levels of additives and/or lower levels of crosslinking irradiation or chemicals. The lower levels of additives and/or crosslinking produce crosslinked UHMWPE having desired physical properties not possible without the synergistic interaction of the additives. This crosslinked UHMWPE may be used in medical prostheses such as in bearing components having desired physical properties such as wear resistance and oxidation resistance not possible without the synergistic interaction of the additives.
