    Abstract: An implantation method is described which involves the successive introduction of projecting multilateral needles into the spongy bone of a joint. The needles are symmetrically spaced on the terminal surfaces of the endoprosthesis up to a resistance edge on one portion of an endoprosthesis and up to a resistance surface on a second portion of the endoprosthesis. The remaining free area between the projecting multilateral needles is filled up to the terminal surfaces in the "biological silence" by osteoblasts. The endoprosthesis also includes a glenoid cavity and a head which have round terminal surfaces with the projecting multilateral needles placed thereon. The projecting multilateral needles have different lengths and mutually parallel axes which are perpendicular to the planes in which the round resistance edge of the glenoid cavity and the resistance plane of the head are located.

    Abstract: An artificial hip-joint having a construction capable of reducing abrasion of a polyethylene layer formed within the acetabulum cup when the head of the femur pivots in the acetabulum cup. The artificial acetabulum cup is implanted in the acetabulum of a user's pelvic bone and includes a hollow hemispherical member made of a metal. The polyethylene layer is formed on the inner surface of the hemispherical member. A femur head holder is fixed to the femur. The femur head holder includes a spherical metal femur head pivotally held in the artificial acetabulum cup, a shaft coupled at an upper end thereof to the femur head and adapted to support the femur head, a housing extending inclinedly through the greater trochanter of the femur and adapted to receive the shaft therein in such a manner that it rotates with respect to the shaft, and bearings mounted between the shaft and the housing and adapted to support axial and radial load applied to the shaft at the femur head by the weight of the user. The bearings allows the housing to rotate with respect to the shaft when the user performs a movement involving a rotation of the femur head in the acetabulum cup, so that the movement of the user can be conducted while preventing the rotation of the femur head in the acetabulum cup.

    Abstract: A kit for implanting a socket joint implant has an outer cup (1), an inner cup (2) and fasteners (3, 3a) which are fitted to radially project from the outer cup (1). Each fastener includes a bearer plate (17) arranged on a shaft-like supporting part (18) which is able to bear in an anchoring bore (6) in the bone tissue (5), and a head part (20) which is connected detachably to the supporting part (18) and can be screwed tight from the inside of the outer cup (1) into a guide bore (11) of the cup. The supporting part (18) has a diameter (A) which is less than the diameter (d1) of the guide bore (11). The kit is pre-assembled outside the region of implantation and positioned in the region of implantation while the fasteners (3, 3a) are pulled in towards the center of the outer cup (1). The fasteners (3, 3a) are then pushed into the anchoring bores ( 6) and screwed tight to the outer cup (1) with head parts (20). The kit is adaptable to different anatomical conditions and may be employed as a replacement for a part of the pelvis missing in the region of the hip socket.
