Surgical procedures for hip prosthesis revision (THA) due to aseptic mobilization of the acetabular component with Paprosky type II and III acetabular defects may entail the use of bone grafts. Autografts have the best biological and mechanical properties but require harvesting, thus increasing possible complcations. Allografts have excellent biological properties but have significant costs. Xenografts, appropriately made antigen free, have already been in use in maxillo-facial and traumatological surgery with good results, since they feature low costs associated to mechanical and biological properties similar to those of allografts.
