ABSTRACT
Total hip arthroplasty is one of the most successful surgical procedures of the last century. Periprosthetic osteolysis and aseptic loosening is the most common cause of failure. The incidence of revision surgery has increased with the increasing number of primary hip arthroplasties petformed annually worldwide. Loss of bone stock is the major challenge at revision hip arthroplasty. This has been addressed, with good medium-term results, by morselized impaction allografting [1]. However, there are now concerns over availability [2-4], infection [5-7], and cost [8].
