title: Bone formation by revascularized periosteal and bone grafts, compared with traditional bone grafts.
abstract: Three groups of dogs were studied to compare the bone formation obtained with traditional bone grafting techniques, and that obtained with revascularized periosteum or revascularized bone grafts--all in unstressed bone. Revascularized periosteum did not produce a significant amount of bone in this unstressed model. At 4 months the revascularized rib grafts had a slightly greater tolerance to stress at the callus site than traditional bone grafts, but the incidence of non-union was the same. We conclude that the use of revascularized bone grafts should be reserved for situations in which traditional bone grafting techniques are unlikely to be successful.
