Management of Acetabular Bone Loss in Revision Total Hip Arthroplasty.

Revision total hip arthroplasty in patients with acetabular bone loss is a challenge and should only be performed by experienced surgeons. Correct classification of the acetabular bone loss pattern allows for the formulation and execution of a detailed treatment plan. However, reclassification of the bone loss pattern is essential if additional bone loss is discovered intraoperatively so that the patient is appropriately treated. Modular, uncemented, porous metal augments and a jumbo acetabular cup should be used to treat patients with severe acetabular bone loss (Paprosky type IIIA and type IIIB acetabular defects).
