摘要： The present invention relates to a prosthetic device for placement in an implant area of the body. The prosthetic device comprises an elongated stem portion, a neck portion, and a head portion. Each of the stem, neck, and head portions comprise a material impregnated with an antibiotic agent such that, when the prosthetic device is inserted into the implant area in place of a weight-bearing prosthesis, the antibiotic agent can leach out of the material to fight infection in the implant area. As an added benefit, the structure of the prosthetic device maintains adequate joint spacing in opposition to contraction of the muscles and tendons of the patient over a period of time so that a weight-bearing prosthesis can again be implanted into the implant area after the infection has been overcome.

摘要： A prosthesis which can be implanted into the cavity of a bone or between spaced apart bones defines a passage with ports for evacuation of air and/or other matter from the cavity or cavities which are to receive bone cement or other cement. The prosthesis is inserted and centered prior to introduction of cement, and its passage or passages are connected to a suction generating device during admission of cement. If necessary, the prosthesis can be confined in a jacket to prevent overheating of adjacent tissue during polymerization of the introduced mass of cement. The passage or passages in the prosthesis can be filled with cement and/or with medications which penetrate into the adjacent tissue subsequent to implantation of the prosthesis.

摘要： The stem of the femoral head prothesis has a distal zone of cylindrical cross-section and a proximal zone of rectangular cross section which extends from the distal zone. The sides of the stem in the proximal zone are plane with outstanding parallel ribs which can be driven into the spongy tissue of a femur bone. The ribs on the anterior side of the stem are of a lower height than the ribs on the posterior side. The outermost ribs on each side provide for a resilient four-point bearing on the hard cortical shell of the fem>r bone. A pair of trochanter wings are provided on the narrow lateral side to penetrate into the cortical shell of the femur bone in order to preclude rotation of the stem within the bone.

摘要： A hip-joint prosthesis which provides for universal motion about three transverse pivot axes comprising a femoral member adapted to be coupled to the femur and a cup assembly partially receiving the femoral member. The cup assembly is slidably received in the acetabulum. Motion about one of the pivot axes can occur in the prosthesis and motion about the other two pivot axes is forced to occur between the cup assembly and the acetabulum.

摘要： A hip joint prosthesis comprises a femoral component having an elongated shank formed of a metal alloy and a joint head adapted to cooperate with the natural acetabulum or a prosthetic acetabulum likewise formed of a metal alloy. The shank has approximately the same width in the lateral-medial plane and a slightly downwards tapered width in the anterior-posterior plane.

摘要： An implantable compensating sleeve is applied between an oblong implant section of a first implant, and a second implant that encloses the oblong implant section of said first implant. The compensating sleeve has a sheath having a sheath body and a passage, running from the proximal to the distal end of the sheath body, for receiving said oblong implant section of the first implant. The sheath body is divided, by slits which cut into the sheath body in the longitudinal direction and originate alternately from the distal and from the proximal edge of the sheath body, into meander-like segments each comprising two longitudinal arms. The sheath body is radially expandable in at least one subsection. On the inner surface of the sheath body facing the passage, at least one bulge extends in the longitudinal direction of a meander-like segment, forming an inner profile that protrudes into the passage.
