[Femoral neck prostheses].
The survival rates of cementless femoral neck prostheses are lower than for cementless standard stems. Nevertheless, femoral neck prostheses have the advantage of preserving the femoral neck as well as not opening the diaphyseal marrow cavity. Should the need to change the endoprosthesis arise, a standard stem anchored in the diaphysis can be implanted after resection of the femoral neck. Since there is a relationship between surgical error and the learning curve for a new implant, the surgeon should be experienced in the field of total hip arthroplasty. In addition, the implantation of femoral neck prostheses is technically demanding. Therefore, careful patient selection is necessary and patients have to be informed of the advantages as well as the disadvantages of the different implant models.
