Claim:
1. A medical device for implantation in a hip joint of a patient, the hip joint having a caput femur integrated with a collum femur having a collum and caput center axis, extending longitudinally along the collum and caput femur, in the center thereof, wherein said medical device comprises: a) an elongated portion being connected to a prosthetic spherical portion adapted to replace the caput femur, and b) wherein said prosthetic spherical portion is adapted to be movably placed in a prosthetic replacement or the acetabulum, the prosthetic replacement for the acetabulum being fixated to the pelvic bone and having at least one extending portion for clasping said prosthetic spherical portion, wherein, i) said prosthetic spherical portion and elongated portion together are asymmetrically sized and formed for replacing the proximal portion of the femoral bone, ii) said elongated portion comprises a restricting portion adapted to restrict the motion range of the prosthetic replacement for the acetabulum in relation to said spherical portion, and wherein iii) said elongated portion comprising a receiving portion being placed frontal to the coronal pelvis plane for receiving a portion of said prosthetic artificial acetabulum, wherein said receiving portion makes the elongated portion rotationally asymmetric around the collum and caput center axis so that said restricting portion of said elongated portion is enables an advantageous motion range in relation to said prosthetic replacement for the acetabulum, when implanted and being in a defined base position.
