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： A liquid chamber (3) arranged in the bottom of the socket cavity (2) is latitudinally sealed by the engaging ball head (4) of the femoral prosthesis shaft. The ball head (4) of the hip joint prosthesis is supported hydrostatically by the liquid chamber (3) filled with synovia and sealed by the ball head following a deformation of the elastic sealing edge (5). By means of the hydrostatic support, the friction moment increases only a little when the load becomes higher and approaches a constant value which is considerably lower than in conventional hip joint sockets.
