Late results of structural allografting of the acetabulum are quite variable. In order to reduce or avoid the necessity for bone grafting, some modified cups have been developed. The deep cup with or without a lateralized polyethylene liner reduces the problem of the protrusio socket. Oblong or bilobed ingrowth cups significantly reduce the need for grafting of the roof-deficient acetabulum. Constrained or capture polyethylene liners are useful in the unstable hip.
髋臼结构移植的远期结果差异很大。为了减少或避免植骨的必要性，已经开发了一些改良的髋臼杯。带有或不带有外侧聚乙烯内衬的深髋臼杯减少了髋臼突出的问题。长方形或双叶长入型髋臼杯显著减少了髋臼顶部缺损时的植骨需求。限制性或卡压式聚乙烯内衬对不稳定髋关节有用。
