[Osteosynthesis with 2-octylcyanoacrylate and sodium bicarbonate in zygomatic arch fractures: animal model results]. / 2-octilcianoacrilato y bicarbonato de sodio para osteosíntesis de arco cigomático. Un modelo animal.

BACKGROUND: 2-octylcyanoacrylate (2OCA) is a liquid monomer that polymerizes on contact with a surface by an exothermic reaction creating a strong and flexible film. The addition of sodium bicarbonate accelerates the polymerization. The aim was to use the combination of 2OCA and sodium bicarbonate in the treatment of zygomatic arch fractures in an animal model and to evaluate the biocompatibility and bone healing. METHODS: twenty animals were subjected to bilateral zygomatic arch fracture under surgical sedation, and using 2OCA fixation and sodium bicarbonate for the experimental side and without fixation for the control side. Observation was over a period from two to four weeks, assessing biocompatibility, stability and consolidation. RESULTS: at the end of two and four weeks the twenty animals showed the presence of osseous callus and continuity of marrow channel measured by macroscopic and radiography examinations. CONCLUSIONS: the use of 2-octylcyanoacrylate and sodium bicarbonate led to the stabilization and reduction of bilateral zygomatic arch fractures in an animal model without adverse reactions.
