Acetabular revisions with bipolar prostheses and particulate bone grafting are seldom performed because of the clinical success of porous coated cementless acetabular components. When limited to cavitary defects and appropriate-sized implants, durable reconstructions with excellent clinical function can be achieved with bipolar revisions. Recalcitrant instability of total hip arthroplasty remains an indication for bipolar revisions.
由于多孔涂层非骨水泥髋臼组件在临床上取得了成功，很少进行双极假体和颗粒状骨移植的髋臼翻修术。当仅限于腔隙性缺损和尺寸合适的植入物时，双极翻修术可以实现具有出色临床功能的持久重建。全髋关节置换术后顽固性不稳定仍然是双极翻修术的一个指征。
