摘要： A femur fixture for a hip-joint prosthesis comprising an intraosseous anchoring structure of a generally circular cross-section for screwing laterally into a complementary bore drilled laterally into the neck of a femur after resection of the femur head to an anchored position. The intraosseous anchoring structure has a proximal end, a distal end, a relatively short frusto-conical proximal section at the proximal end, and a proximal cylindrical section having a screw thread profile thereon. The proximal cylindrical section extends from the frusto-conical proximal section towards the distal end of the anchoring structure. The frusto-conical proximal section and the proximal cylindrical section each being dimensioned so as to bear against the cortex of the femur neck when the intraosseous anchoring structure is in the anchored position. The invention also relates to a set of such femur fixtures, wherein the frusto-conical proximal section and the proximal cylindrical section of each fixture in the set have different dimensions, whereby the fixture in the set having the frusto-conical proximal section and the proximal cylindrical section of correct size for abutting the cortex of the femur neck of a particular patient can be selected for use in that patient.

摘要： The invention relates to an arrangement for fixing a knee-joint in connection with prosthetic surgery. The arrangement provides for a fixing of the operated knee-joint relative to a reference, which is represented by the operating table. The purpose is to positionally control, with high precision, measuring and cutting instruments in the prosthesis operation. The arrangement includes an alignment instrument (11) for aligning and fixing both the femur (66) and tibia (21) relative to a reference axis in both the frontal plane and the sagittal plane, which alignment instrument comprises a fixture (4) for the trunk. The fixture is adjustable and can be locked in selected positions by displacement transverse to the reference axis. The alignment instrument also comprises a further fixture for fixing the knee-joint (20, 22) and tibia (21). The arrangement moreover comprises a positional control unit for positional control of measuring and cutting instruments. This permits a controlled, precise and delicate bone-cutting, which creates the conditions for the desired positioning and exact fitting between prosthesis bed and prosthesis.

摘要： Knee-joint prosthesis for permanent anchoring in the bone tissue of a knee-joint in the human body, consisting of a femur part, which comprises an articulation element (8) with a convex joint surface (20), an elongate intermediate element (7) with a first side, intended to bear against a surface of the bone tissue, and a second, opposite side intended to bear against an inner surface of the articulation element, which is arranged securely on the intermediate element by means of a positive locking. An anchoring element intended to be introduced into a recessed channel in the bone tissue and to be connected to this for anchoring the intermediate element and, thus, also the articulation element in the femur. The positive locking for securing the articulation element (8) for the femur on the intermediate element (7) in the femur part (3) is formed by means of the intermediate element being designed as a fixation rail with flanges (13) arranged on the second side of the intermediate element and by means of the rear surface of the articulation element for the femur being provided with an elongate fixation member (26) extending along this surface. This member is designed to be introduced into the said fixation rail and locked in the latter in a predetermined locking position by means of locking members (29).

摘要： The invention is directed to a reamer for shaping a bone socket such as an acetabular cavity. The reamer comprises a cutting head for removing material from the socket during rotation of the cutting head. The cutting head comprises a number of relatively long main cutting edges, each of which extends in a direction from a base to a top of the reamer, and a number, higher than the number of main cutting edges, of relatively short peripheral cutting edges, which are located at the base and distributed at angulary spaced intervals about a rotational axis. The invention also provides a method for implanting a prosthesis component into a bone socket. During shaping of the bone socket, a top portion of the reamer is completely received in the bone socket to such an extent, that a cylindrical entrance portion is formed in the socket. The invention also provides a kit including a reamer and a prosthesis.
