Acetabular revision with the bipolar prosthesis and particulate bone grafting.
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.
