Abstract: A method of implanting a hip joint prosthesis into a patient can include obtaining image data of hip joint anatomy of the patient. Physical activities that the patient desires to participate in subsequent to implanting the hip prosthesis can be determined. A size and an initial placement of the hip joint prosthesis based on the image data can be determined. A desired range of motion of the hip joint prosthesis based on the determined physical activities can be determined. A plan can be created comprising a desired implanted location of the hip joint prosthesis and based on the desired range of motion. The plan can be incorporated onto a guide. The plan can be executed with the guide thereby implanting the hip joint prosthesis into the patient at the desired implanted position.

Abstract: An orthopaedic tool includes a handle having an exterior profile defined by a first three-dimensional shape having an exterior surface of revolution about a first axis of rotation, and a second three-dimensional shape having an exterior surface of revolution about a second axis of rotation. The second axis of rotation is offset from the first axis of rotation, whereby the first three-dimensional shape and the second three-dimensional shape intersect to define a volume of intersection. The exterior profile is defined only by the volume of intersection. A shaft extends from the handle.

Abstract: The joint implant manufacturer obtains and compiles surgeon-specific surgical and supply preference information in relation to a supplied joint implant prior to surgery. The manufacturer designates and trains at least one surgical team member using the surgeon-specific preference information and then supplies the service of the surgical team member(s) together with the supplied joint implant and supplies. The surgical team member(s) perform surgical procedures on the patient to assist the surgeon in removing a defective joint and replacing it with the supplied implant in accordance with the surgeon's surgical preferences.

Abstract: A tibial anchoring assembly comprising a tibial tray and an anchor. The tibial tray comprises an upper surface for engagement with a femoral component and a lower surface for engagement with a tibia bone. The lower surface defines at least one retaining aperture. The anchor is adapted to compressively couple the tibial tray to the tibia bone. The anchor comprises a longitudinally extending base, a top section coupled to the base and having a shape to be received into the retaining aperture of the tibial tray, and a flexible blade member protruding from the base. The flexible blade member is adapted to be flexed in tension while being inserted into the tibia bone, thereby exerting a compressive force between the tibial tray and the tibia bone. A deforming fixture may be used to shape the flexible blade member. Methods of affixing an implant to a bone structure are also provided.

Methods for inhibiting infection at the site of implantation of an orthopedic device in a human or animal subject, comprise rubbing a surface of the device, prior to implantation, with an infection-inhibiting composition having a waxy matrix comprising an infection-inhibiting material selected from the group consisting of a lipid, an antimicrobial agent, and mixtures thereof, wherein a thin layer of the infection-inhibiting material is deposited on the surface of the device. Medical implants which may be treated in the methods of this technology include orthopedic implants. Lipids include long-chain diacylglycerides or triacylglycerides, which may be saturated or unsaturated, such as lecithin or a purified form of phosphatidylcholine.

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.
