Revision of the femoral prosthesis with impaction allografting.

Impaction allografting is the only technique, to date, that has been shown to reverse the loss of bone stock encountered during revision hip arthroplasty. However, early stem subsidence, dislocations and a high occurrence of periprosthetic fractures are well documented with this method. This article reviews the biomechanical and biological characteristics of compacted morsellised graft, on the femoral side, and examines the clinical results of this technique and its future development.
