Resum
Thirty five revision hip arthroplasties performed in 29 patients with acetabular bone defects were reviewed. In this series we only include the acetabular reconstruction performed using non cemented acetabular implants. The mean age of the patients was 60 years (29-79), 19 were female and 10 male. We classified the acetabular bone defects according to D'Antonio, in segmentary, cavitary and combined. To repair these defects, we used criopreserved allograft, except one case in which a liofilized allograft was used. The results were evaluated clinically (modified Harris hip score) and radiographically, looking for acetabular migrations, radiolucent lines, periarticular ossifications and bone graft incorporation. We obtained 60% of excellent and good results. There was 40% of poor and fair results. The acetabular loosening rate was higher than in revision hip arthroplasty without acetabular bone defects.
