    Abstract: A coating of blue-black or black oxidized zirconium of uniform and controlled thickness on a zirconium or zirconium alloy material is accomplished through the oxidative treatment of an amorphous zirconium or zirconium alloy substrate having an altered surface roughness. An oxidized zirconium coating of uniform and controlled thickness is especially useful on orthopedic implants of zirconium or zirconium-based alloys to provide low friction, highly wear resistant surfaces on artificial joints, such as, but not limited to, hip joints, knee joints, shoulders, elbows, and spinal implants. The uniformly thick oxidized zirconium surface of controlled depth on prostheses provide a barrier against implant corrosion caused by ionization of the metal prostheses. The invention is also useful in non-articulating implant devices such as bone plates, bone screws, etc.

    Abstract translation: 通过氧化处理具有改变的表面粗糙度的无定形锆或锆合金基体，在锆或锆合金材料上形成均匀和受控厚度的蓝黑或黑氧化锆涂层。 具有均匀和受控厚度的氧化锆涂层特别适用于锆或锆基合金的整形外科植入物，以在人造关节（例如但不限于髋关节，膝关节，肩部）上提供低摩擦，高度耐磨表面 ，肘部和脊柱植入物。 假体上的均匀厚度的受控深度的氧化锆表面提供了对由金属假体的电离造成的植入物腐蚀的阻挡。 本发明在非关节式植入装置例如骨板，骨螺钉等中也是有用的

    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: A prosthetic device may comprise an insert having a first surface configured to contact a first prosthetic component and a bearing surface configured to articulate against a second prosthetic component. The insert comprises an ultra-high molecular weight polyethylene and vitamin E. The vitamin E may have a concentration in the range of.02 to.12 wt% first mixed with the ultra-high molecular weight polyethylene and then molded with the ultra-high molecular weight polyethylene at a temperature greater than the melting point of the ultra-high molecular weight polyethylene. The ultra-high molecular weight polyethylene and vitamin E may be gamma irradiated with a dosage of radiation between 5 and 20 Mrad. The insert may be machined prior to gamma irradiating the insert in air such that the gamma irradiation, at suitably high dosages, may also sterilize the insert.
