Vascularized bone allografts: an experimental study in dogs.

This study attempted to re-establish vascularization to canine allograft bone by means of the introduction of a pedicle in the medullary canal with a capillary network. The experiment showed basically that the introduction of arteries and veins with a capillary network into the medullary canal of an allograft femur provided enough vascular supply to produce fibrous tissue and enough bone to cover preoperatively drilled holes, suggesting that the allograft "revives" with the introduction of a vascular supply.
