Impaction Grafting Using a Cemented Porous-Coated Modular Acetabular Component

Abstract

Reconstruction of major acetabular defects continues to challenge surgeons. There are many surgical options for these situations, including oversized hemispherical cups, oblong cups, acetabular cages, bulk allografts, and impaction allografting. We present the case of a modification to the impaction grafting technique for acetabular reconstruction. In our case, a porous-coated modular titanium acetabular component was cemented in place instead of an all-polyethylene acetabular component, which is the standard technique for impaction grafting reconstruction. The use of the modular component allowed a greater number of surgical options at the time of surgery. At 5 years from surgery, the patient has a successful reconstruction and the radiographs continue to look excellent.
