Abstract :

Comparative investigation on capacity of vascularized corticoperiosteal tibial flap to produce heterotopic osteogenesis in dogs versus rabbits. Methods – Proximal tibial flap was taken and transferred in the popliteal muscle. The development of the flap and the new formed bone were evaluated by digital computer image – radioopacity, bone mineral density, osseous resorption and bone quality. Results – In rabbits the bone mineral density increased to values close to the reference value of normal tibial bone tissue. In dog, contrariwise, a marked decrease was observed. Histological sections in rabbit revealed that the regenerated tissue shows a high functional organization level and in the dog revealed the presence of the osseous resorption process. Clinical significance – The heterotopic flaps have different behavior in dog from rabbits. Dog’s developmental model confirms the incapacity of the osteogenic reaction of the vascularized corticoperiosteal flaps in heterotopic transplantation.
