Abstract: Solid-state deformation processing of crosslinked high molecular weight polymers such as UHMWPE, for example by extrusion below the melt transition, produces materials with a combination of high tensile strength and high oxidative stability. The materials are especially suitable for use as bearing components in artificial hip and other implants. Treated bulk materials are anisotropic, with enhanced strength oriented along the axial direction. The material is oxidatively stable even after four weeks of accelerated aging in a pressure vessel containing five atmospheres of oxygen (ASTM F2003). Because of its oxidative stability, the deformation processed material is a suitable candidate for air-permeable packaging and gas sterilization, which has thus far been reserved for remelted crosslinked UHMWPE.

Abstract: A ceramic implant having a rough surface texture and a method for forming the same. The method includes forming a green body of a first ceramic composition. The green body is reduced to smaller pieces thereby forming ceramic fragments. A mold is filled with a second ceramic composition to form a ceramic base. Ceramic fragments are added to the mold and an outer layer is formed over at least a portion of the ceramic base. Pressure is applied to the mold to compress the outer layer onto the ceramic base and to form a green assembly. The green assembly is sintered to form a ceramic implant having a rough surface texture.

Abstract: A press-fit prosthesis for replacing a portion of a bone. The prosthesis can comprise a first side and a second side opposite the first side. The second side can be operable to engage the bone. The prosthesis can include at least one resorbable fixation member coupled to the second side such that the at least one resorbable fixation member does not extend through to the first side. The at least one resorbable fixation member can be coupled offset from a center of the second side. The at least one resorbable fixation member can substantially resist movement of the prosthesis relative to the bone. The at least one resorbable fixation member can resorb at a rate that enables bone in-growth to fixedly couple the prothesis to the bone.
