Resumen (ES)
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.
