Hip joint endoprosthesis assembly - has socket attached to pelvis bone by support plate and uses biologically absorbent material for the support plate

摘要

The endoprosthesis for replacing the hip joint of a human patient has a prothetic socket which is fastened to the pelvic bone by a support plate. The support plate (2) is made from biologically absorbent material whilst the socket has a socket shell (22) made of metal and a socket insert (26) made of plastics. The socket (20) is attached to the support plate and/or to the pelvic bone by a method which does not use cement. The outer surface of the socket shell has an open cellular structure. ADVANTAGE - The endoprosthesis is securely anchored to the bone without causing any distortion of the bone.
