1. A method for treating hip joint osteoarthritis in a human patient by providing at least one medical device comprising an artificial hip joint surface, the hip joint comprising an acetabulum, being a part of a pelvic bone, and a caput femur being a part of a femoral bone, and having a partly spherical form having a largest diameter, wherein said medical device comprises:
a prosthetic part adapted to function as an articulating surface comprising a center axis generally coinciding with the acetabulum and the caput femur center axis when implanted,
the method comprising the steps of:
placing the prosthetic part in a through-going hole in the pelvic bone from an abdominal side opposite a concave portion of the acetabulum of the human patient,
radially displacing a plurality of displaceable protruding supporting members distributed circumferentially around the prosthetic part

such that the plurality of displaceable protruding supporting members are configured to transfer load from the prosthetic part via the displaceable connection to the pelvic bone when being displaced relative said prosthetic part in a direction more perpendicular than parallel to the prosthetic part's center axis and being implanted.
