Objective: To evaluate the effect of butyl-2-cyanoacrylate tissue adhesive in osteotomies and bone grafts, with regard to macroscopic and radiographic characteristics. Methods: Forty-eight rabbits were used, randomly divided into four groups of 12 animals, with observation periods of two, four, eight and 16 weeks. Both thoracic limbs were operated in each animal and two osteotomies were performed in each of the radii, withdrawing a bone fragment (bone graft) of 1 cm in length. On one side, the bone graft was then replaced and a drop of adhesive was applied to each of the osteotomies. On the other side, the same procedure was performed without applying the adhesive. The rejection level for the nullity hypothesis was set at 0.05% or 5%. Results: Blue marks were present in all the surgical
