Hip Joint

A surgical method of treating a hip joint of a human patient by providing a medical device, the hip joint comprising an acetabulum being a part of the pelvic bone, and a caput femur being connected to the proximal part of the collum femur and being the upper extremity of the femoral bone, the collum femur and caput femur further comprises cortical bone and cancellous bone, said surgical method comprising the steps of:

• cutting the skin of said human patient,
• dissecting an area of the pelvic bone on the opposite side from the acetabulum,
• creating a hole in said dissected area, said hole passing through said pelvic bone and into the hip joint of said human patient,
• removing, at least partly, the caput femur from the femoral bone,
• removing a part of said cortical bone of the caput femur from the caput femur,
• attaching said part of said cortical bone of the caput femur to a medical device, and
• attaching said medical device with said part of said cortical bone of the caput femur to the collum femur
• stabilizing the collum femur with a stabilizing member.

A surgical method of treating a hip joint of a human patient, by providing a medical device, the hip joint comprising an acetabulum being a part of the pelvic bone, and a caput femur being connected to the proximal part of the collum femur and being the upper extremity of the femoral bone, the collum femur and caput femur further comprises cortical bone, outer sclerotic bone, and cancellous bone, in the bone marrow, said surgical method comprising the steps of:

• cutting the skin of said human patient,
• dissecting an area of the hip,
• removing, at least partly, the caput femur from the femoral bone, sparing the proximal part of the collum femur,
• attaching said fixating member to said proximal part of the collum femur, direct or indirect, and
• placing said artificial caput femur surface in the acetabulum or an artificial acetabulum replacement, and
• closing the wounds, if necessary in steps.
