| 摘要 |
The invention relates to a bone prosthesis for adapting to a femoral stump (1). The prosthesis is comprised of an adapter, which is to be anchored inside the femoral stump in an intramedullar manner and which is provided for a knee joint (3) to be extracorporeally coupled to the adapter, and is comprised of a lower leg prosthesis (4) that can be coupled to the knee joint (4). In order to prevent the femoral stump (1) from fracturing, a specified rupture point (5) is extracorporeally provided in at least one prosthesis part that permits the prosthesis part to break open when a predetermined force is exceeded. This results in preventing damage inside the femoral stump (1) and, in particular, on the adapter anchored in an intramedullar manner due to the fact that a rupture of the prosthesis is extracorporeally induced when stresses occur that exceed a predeterminable specified value.
