A vascularized fibula model to study vascularized canine bone grafts.

We have refined the experimental canine vascularized fibula model in 26 dog experiments. Our results have demonstrated that both periosteal and endosteal blood flow are retained following end-to-end anastomosis of the bone graft pedicle artery and vein. The success of this model depends on detailed knowledge of the surgical anatomy and upon meticulous microvascular surgical technique.
