    摘要: A prosthetic hip joint comprises a femoral element formed with a ball head and a stem projecting from the head and adapted to be received within the upper end of a femur, and a generally hemispherical socket element adapted to be secured in the ilium at the acetabulum thereof and having an inner surface formed as a generally hemispherical cavity adapted to snugly receive the ball head. The outer surface of the socket element is subdivided at a step into a lower quarter-spherical region having a center of curvature lying above the center of curvature of the ballreceiving cavity, and an upper quarter-spherical region adjoining the lower region and having a center of curvature coinciding with the center of curvature of the ball-receiving cavity. The step between the two quarter-cylindrical regions is formed with a chamfer and both of these regions are formed with a plurality of criss-crossing grooves, in at least one of which is received a metal wire allowing the synthetic-resin socket element to be viewed in an X-ray. The ball head of the femoral element is formed with a neck that is tapered into the stem and forms a pair of shoulders thereon.

    摘要: An artificial hip joint socket made of plastic is intended to be installed in the pelvic bone without bone cement. The hip joint socket comprises a ribbed outer surface which permits good engagement of the bone tissue as well as two anchor plugs protruding from the outer surface which are intended to be inserted into corresponding bores in the bone. The angle which the plugs form with the socket surface deviate from the angle which the bores form with the socket surface by about 5.degree. in order to effect a predetermined prestressing action which restrains the hip joint socket in position. Furthermore, the hip joint socket comprises at least two barb-like anchor flaps on its outer surface which either lie opposite one another or mutually include an angle of between 120.degree. and 150.degree.. A good seating of the hip joint socket in the bone is ensured by these flaps even immediately after insertion of the hip joint socket. Thus, even if the anchor plugs offer insufficient retention for any reason, the employment of screws or dowels can be completely or partially foregone.

    摘要: An artificial hip joint having an acetabulum prosthesis for the cotyloid cavity defining a socket and including a head having a plurality of blades extending outwardly away from the socket for engaging the prepared wall of the cotyloid cavity and having at least one insert removably connected to the head to form the socket. A prosthesis of the head of the femur is movably interconnected with the acetabulum prosthesis and includes a pin to be driven into the bone-marrow channel of the femur, a curved neck integral with the pin, and a hip ball positioned on the neck, movably located within the socket and in movable contact with the removable insert. Means are provided in operative relationship with the femur head prosthesis for preventing rotation of the femur head prosthesis with respect to the femur.
