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.
非骨水泥型股骨颈假体的生存率低于非骨水泥型标准柄假体。然而，股骨颈假体具有保留股骨颈以及不打开骨干骨髓腔的优点。如果需要更换内置假体，可以在切除股骨颈后植入固定在骨干中的标准柄。由于手术误差与新植入物的学习曲线之间存在关联，外科医生应在全髋关节置换领域有经验。此外，股骨颈假体的植入在技术上要求很高。因此，必须仔细选择患者，并且必须告知患者不同植入模型的优缺点。
