ARTIFICIAL HIP JOINT

Japanese Patent JPH1156884

A

PROBLEM TO BE SOLVED: To enhance productivity while maintaining the impact absorptivity by a liner formed of a resin material by forming the sliding part of an acetabular roof socket of ceramics, constituting the sliding part of an approximately columnar-shaped part and a dome-shaped part and press fitting the sliding part into the internal space of the liner. SOLUTION: The system body comprises a material having less vital harmfulness and the acetabular roof socket 5 is fixed to the pelvis side and comprises the sliding part 6 made of ceramics and the liner 7 made of the resin fitting the sliding part 6. The socket slides and seats with the head sphere of the bone by the approximately hemispherical sliding surface 8 of the sliding part 6. The sliding part 6 comprises the approximately columnar-shaped part 6a and the dome-shaped part 6b and is carried in the state of being press fitted into the internal space 10 of the liner 7 by a claw 11 projecting from the opening peripheral edge 9 of the liner 7 into the internal space. Namely, the sliding part 6 is fixed in the position on the side deeper than the claw 11 and, therefore, the stem neck fixing the head sphere of the bone may be seated by the opening peripheral edge 9 of the liner 7 made of the resin.
