Today, alloarthroplasty is one of the many standard therapeutical procedures in osteoarthrosis of the hip, or coxarthrosis. With this operation, many patients can be completely relieved from pain and regain their ability to walk to an excellent degree. However, long-term observations have shown that the stability of the prostheses does not always correlate with the life expectation of the operated patient. Dislocations and states of irritation, over and above infections, may necessitate repeat surgery. It must be borne in mind that such repeated operations are by no means certain to produce safe results. Hence, it is recommended to employ for the first implantation a prosthesis model which offers a better chance of interchangeability. This possibility is supplied by the double-cup prosthesis of the type described by Wagner and other authors. Certain limitations are imposed by the prosthetic form and by the surgical approach; these limitations should be taken into account when choosing the double-cup prosthesis.
如今，全关节置换术是髋关节骨关节炎（即髋关节炎）众多标准治疗方法之一。通过这种手术，许多患者能够完全缓解疼痛，并在很大程度上恢复行走能力。然而，长期观察表明，假体的稳定性并不总是与接受手术患者的预期寿命相关。除感染外，脱位和刺激状态可能需要再次手术。必须牢记，这种重复手术绝非一定能产生安全的效果。因此，建议在首次植入时采用具有更好互换可能性的假体模型。瓦格纳及其他作者描述的那种双杯假体就提供了这种可能性。假体的形式和手术入路存在一定限制；在选择双杯假体时应考虑到这些限制。
