Introduction

Reconstructing acetabular defects in revision hip arthroplasty can be challenging. Small, contained defects can be successfully reconstructed with porous-coated cups without bone grafts. With larger uncontained defects, a cementless cup even with screws, will not engage with sufficient host bone to provide enough stability.

Porous titanium augments were originally designed to be used with cementless porous titanium cups, and there is a scarcity of literature on their usage in cemented cups with bone grafting.

Methods

We retrospectively reviewed five hips (four patients – 3 women, 1 man; mean age 65 years) in which we reconstructed the acetabulum with a titanium augment (Biomet, IN, USA) as a support for impaction bone grafting and cemented acetabular cups (Figure 1). All defects were classified according to Paprosky classification. Radiographic signs of osseointegration were graded according to Moore grading. Quality of life was measured with the Oxford Hip Score.
