The photoacoustic analysis of fractured bone callus to different consolidation times in presence of the irradiation laser, was performed. In this study we take into account the fractured tibias of sacrified Wistar rats. By using photoacoustic spectroscopy (PAS) technique it was possible to determine, for different doses of laser irradiation (doses from 5 to 10 Jcm-2) the presence of characteristic absorption peaks of p-Nitrophenylphosphatase (p.Npp) in the fractured bone callus. The evolution of bone consolidation was accelerated by laser radiation when compared with non irradiated fractures bones.
