title: [Femoral neck prosthesis in the case of femoral neck fracture and ipsilateral long stem-knee tumour prosthesis].
abstract: Femoral neck fracture in the case of a previously implanted ipsilateral tumour knee-prosthesis represents a challenging situation because of the long proximal stem of the knee implant. Avoiding total femur replacement, we implanted a femoral neck prosthesis (Eska Cut 2000) in a 65 year old patient to preserve as much of the femur free of implant as possible, minimizing the risk of a periprosthetic or interprosthetic fracture. At 2.5 years postoperatively, there were no signs of loosening, migration or periprosthetic fracture with a good functional result. In our case, the femoral neck prosthesis avoided the implantation of a total femur replacement. Nevertheless, this prosthesis must be considered critically and cannot be recommended as the standard implant for femoral neck fracture in the case of an ipsilateral long stem-knee prosthesis.
