[Comparative studies on the incorporation of autologous and homologous spongiosa in the compact layer of long bones].
The healing of fresh autologous and homologous cancellous bone graft in gaps made in diaphysis was checked in a comparative test series of dogs. The general revascularization comes from the medulla. During the 2nd week the newly formed vessels in the homograft are obliterated. These are rebuilt during the 3rd week. At the same time new bone formation and reabsorption of the implanted bone by osteoclasts cease temporarily. After 6 weeks both grafts are remodeled in lamellar bone. The osseous trabeculae do not yet run parallel to Havers' system of the corticalis. The results verify the superiority of the autologous cancellous bone grafts.
