Massive proximal femoral osteoarticular allograft.

The implantation of massive allografts is a reconstruction alternative after limb salvage for aggressive bone tumours. It is hoped that durable long-term results can be obtained with these biological reconstructions. Revitalization of the allografts is one of the most important factors with regard to durability. One massive proximal femoral osteoarticular allograft is described that was followed up for 22 years. Twenty-one years after the implantation, a traumatic fracture in the middle of the allograft occurred, and formation of massive callus showed that revitalization even in the central parts of massive allografts is sufficient for fracture healing. This is why it may be justified to expect long-lasting results.
