| 摘要 |
The invention relates to a ceramic surface replacement prosthesis (I) for the natural femur head (3), comprising an outer spherical surface (5) and an inner receiving space (7) with an inner lateral surface (4). The aim of the invention is to prevent necrosis of the bone tissue as a result of the implantation process, thus also preventing a loss of inner bone tissue. According to the invention, this is achieved in that the inner lateral surface (4) is provided with an osseointegrative coating (6) or is designed in an osseointegrative manner at least in some areas, and/or the lateral surface (4) is designed as a self forming thread (8). |
