Sumario:Acetabular bone loss is not uncommon when performing revision total hip arthroplasty. This can create a challenge, especially on the acetabular side. In the present report, our patient presented with aseptic loosening of the acetabular component. The patient had a Paprosky IIIA acetabular defect that was reconstructed with stacked acetabular augments in addition to a highly porous acetabular cup. The remaining bone defects were addressed through the use of a calcium sulfate/hydroxyapatite bone graft substitute. We set out to describe how to reconstruct severe acetabular bone loss with a combination of acetabular augments in addition to an injectable bone graft substitute as a novel method to address a complex clinical scenario.
