The authors describe their experience in the treatment of severe acetabular osteolysis using bone grafts and cementless screwed acetabulum. They define the criteria that directed them towards this choice and the surgical method used in relation to bone loss caused by failure of the previous prosthesis. In light of their experience, the advantages and the drawbacks to using a cementless acetabulum in hip reimplantation are described, with particular analysis of the peculiar features of the P.M. acetabulum that, because it is screwed and has a truncated-conical design, permits stabilization of the grafts without the use of further instrumentation, and obtains effective primary stability even when there is discontinuity of the bottom or of the acetabulum.
作者描述了他们使用骨移植和非骨水泥型髋臼螺钉治疗严重髋臼骨溶解的经验。他们确定了促使他们做出这一选择的标准以及针对先前假体失败导致的骨丢失所采用的手术方法。根据他们的经验，描述了在髋关节翻修术中使用非骨水泥型髋臼的优缺点，特别分析了P.M.髋臼的独特特征，因其为螺钉固定且呈截锥形设计，无需使用其他器械即可实现植骨稳定，即使髋臼底部或髋臼出现连续性中断时也能获得有效的初始稳定性。
