Experimental investigation into reparative osteogenesis with fibrin adhesive.

An experimental investigation was carried out in order to evaluate the effects of fibrin adhesive on the reparative osteogenesis of bone grafts in the short, medium, and long term. Sixty fully developed New Zealand White rabbits under general anesthesia were grafted with homologous bone tissue in the proximal third of each tibias. Fibrin adhesive was used in one hind limb only. The animals were killed at a predetermined time. Both tibias were removed and subjected to radiographic and histologic analyses. The reparative process was observed and the differences between the fibrin adhesive-treated grafts and the reference group in the first few weeks were determined. No substantial difference was detected in the reparative osteogenetic process of the graft in the animals killed after 2 months.
