title: Comparison of fresh autogenous with formalin preserved allogeneic bone grafts in rabbits. An experimental study.
abstract: A complete circumferential gap was produced in the diaphysis of the ulna in rabbits and the radius was left intact. The gap on the right side was filled with formalin preserved allogeneic (FPA) bone graft, and fresh autogenous bone taken from the right ulna was put into the gap on the left side. The gap was left untouched in a control group. Up to 8 weeks, the rate of union was slower in the FPA grafts compared with the autogenous grafts. Maximum fluorescence was seen at 10 to 16 weeks and was the same in both groups. These results indicate that osteoinduction occurs with normal bony repair in 80% of both groups, although the onset of healing is delayed in the FPA grafts.
