Abstract
A medical device for treating hip joint osteoarthritis by providing a joint surface is provided. The medical device has at least two artificial hip joint surface parts adapted to be connected to each other to form an artificial hip joint surface during an operation. A method of treating a hip joint of a human patient by providing the medical device is also provided. The method includes cutting the skin of the human patient, dissecting an area of the pelvic bone on the opposite side from the acetabulum, creating a hole in the dissected area passing through the pelvic bone and into said hip joint and providing the medical device to the hip joint, through the hole in the pelvic.

A medical device kit for assisting in the attachment of an artificial caput femur surface to an artificial acetabulum surface, in an artificial articulating hip joint, the medical device kit comprises:
- a first locking member for locking the artificial acetabulum surface clasping the artificial caput femur surface, wherein the first locking member is configured to, in a first state, to bold the artificial caput femur surface clasped in the artificial acetabulum surface, and, in a second state, release the artificial caput femur surface from the artificial acetabulum surface. and wherein the locking member is adapted to change from the first state to the second state when a first pre-determined strain is placed on the locking member, and
- a second locking member for locking the artificial acetabulum surface clasping the artificial caput femur surface, wherein the second locking member is configured to, in a first state, to hold the artificial caput femur surface clasped in the artificial acetabulum surface, and, in a second state, release the artificial caput femur surface from the artificial acetabulum surface, and wherein the locking member is adapted to change from the first state to the second state when a second pre-determined strain is placed on the locking member, and wherein the second pre-determined strain is larger than the first pre-determined strain.
