    摘要： The joint prosthesis includes a first part with a cylindrical socket and a second part with a cylindrical head. The cylindrical head and socket are of complementary form, in such a manner that together they are able to form a linear hinge. The cylindrical socket extends over at most 180° in the circumferential direction. The cylindrical head is provided with a radial thickened section which extends in the circumferential direction. The cylindrical socket is provided with a radial recess which extends in the circumferential direction and in which the radial thickened section can be accommodated, with the cylindrical head in bearing contact inside the cylindrical socket. The radial thickened section and radial recess are arranged centrally and are formed so as to be self-aligning with respect to one another. The cylindrical head may be arranged on at least one support arm and one or both longitudinal edges of the cylindrical socket may be provided, in the arca of the at least one support arm, with a cutout in which the support arm can be completely or partially accommodated.

    摘要： 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.
