| Abstract: | A modification and the technical details for the implantation of total hip prosthesis is reported. In order to improve stabilisation of the femoral shaft component of the endoprosthesis and to prevent the progress of bone cement also in the distal femoral part of the marrow cavity, the intramedullary cavity is blocked with a bone cylinder prepared from the resected femoral head. Using a special instrument, this bone block is introduced into the intramedullary cavity before filling up the proximal femur with bone cement. Bone cylinders can be prepared and preserved in a bone bank for use whenever necessary. |
