    摘要： A hipjoint socket has an outer cup and an inner cup disposed within and secured to the outer cup. The inner cup has a hemispherical bearing surface which is concentric with an axis and terminates at the end face, which is perpendicular to the axis. An open groove formed in the end face is concentric with the axis. A closed ring has axially relatively longer and shorter portions and a cylindrical guiding surface having a diameter about equal to a diameter of the hemispherical guiding surface. The ring includes tongues engaging the groove and thereby securing the ring to the inner cup when the ring abuts the end face. The tongues are able to slide along the groove and position the cylindrical guiding surface concentric with the axis and substantially contiguous with an end of the hemispherical bearing surface at the end face. The ring can be rotated relative to the inner cup upon the implantation of the socket to position the relatively longer ring portion on the socket where it prevents luxation of a femur head cooperating with the socket.

    摘要： The metallic inner shell (1) is guidable into the inner hollow volume of an outer shell (2) and fastenable to the outer shell (2) with the fastening element (8). A two-part hip joint socket (3) is thus produced. To achieve this, support regions of the inner shell (1) are approximately positioned into a groove (11) of the outer shell (2) and, from there, the inner shell (1) is moved into the outer shell (2) via a pivotal movement so that the support regions completely seat into the groove (11) and the fastening element (8) adopts the position shown. The intermediate volume between the inner shell (1) and the outer shell (2) thus narrows in the direction of taper (13) so that the fastening element (8), when tightened in the direction (13), wedges itself with its head (9) between the boundary surface (1i) of the inner shell (1) and the groove (11) of the outer shell (2). Play between the inner thread (7a) and the outer thread (8a) is preferably provided so that, when the fastening element (8) is tightened, the force transmission region (9b) of the head (9) seats against the boundary surface (1i) of the inner shell (1) and the force transmission region (9a) seats against the groove (11) of the outer shell (2). The inner shell (1) thus lies wedged in the outer shell (2) due to the fact that the fastening element (8) transmits a radially oriented force between the inner shell (1) and the outer shell (2).

    摘要： A screw-nut for screwing implants together includes a thrust-shoulder which projects radially and presses axially against part of a housing. The screw-nut further includes an internal threaded portion adapted to fit a corresponding screw part, and a plurality of members, each mounted onto the side of the thrust-shoulder facing away from the part of the housing against which the thrust shoulder presses. These members are adapted to receive a tool for tightening the screw-nut. A plurality of leaf springs is included for engaging the housing part. The leaf springs, the ends of which form latching-in dogs, project, in the axial direction, from the screw-nut. The leaf springs are constructed such that, when the thrust-shoulder makes contact with the housing part, each latching-in dog snaps into a recess in the housing part in order to prevent loosening of the screw-nut from the housing part.

    摘要： A knee joint prosthesis includes two guide faces for receiving the condyles of a distal femur. The prosthesis includes a tibial plateau of polyethylene which is embedded in a metal tibial shank with a plate. The underside of the plate is planar and bears against a resection area of the tibia shaped as a planar endface. On the inside of the plate, in the region of the guide faces, pockets are formed. The pockets follow the curvature of the guide faces in sagittal planes and exhibit at their lowest point a maximum wall thickness of 1.5 mm, while the minimum wall thickness of the tibial plateau resting in the pockets amounts to 6.5 mm.

    摘要： With the invention is shown a meniscus platform for an artificial knee joint, which consists of a metal platform (1) and a metal slide member (3) sliding thereon at right angles to the tibia axis (17), which on its upper side comprises sliding surfaces (4, 5) and a guide bead (8) for the condyles (13, 14) of a femur part (11). The sliding movement between the metal slide member (3) and the metal platform (1) is restricted by a guiding pin (10) in the metal platform, which engages in an oblong hole (9) in a slide member (3) made of metal. The metal slide member (3) can rotate around the guiding pin (10) and can be displaced along its oblong hole (9). The rotational movement of the slide member (3) is restricted by a limiting recess (15), which encloses a part of the eminentia (19) in the region of the rear cruciate ligament.

    摘要： In some examples, a method for at least one of preparation or machining of a femoral head formed on a neck of a femur includes selecting an instrument including probing forceps and a guide element including a centering axis. The guide element is coupled to the probing forceps at first and second coupling points disposed along the centering axis such that the centering axis is disposed in a central plane of the probing forceps independent of an opening angle of the probing forceps. The probing forceps are closed with probing jaws symmetrically contacting the neck of the femur at opposite sides with respect to an axis of the neck of the femur. The guide element self-adjusts with closing of the probing forceps so that the centering axis is automatically aligned in the middle with respect to the two oppositely disposed sides of the neck of the femur.
