Resumen (ES)

In view of the present importance of Laser Radiation, and due to the lack ofreferences about its effects on the growth cartilage, we designed an experimental model in orderto asses it. A total of 50 rats were used, establishing five groups of study at 10 animals each,depending on the dosis of radiation applied percutaneously on the distal femoral phisys. Afterthe structural, histochemical and morphometric study, we observed a series of alterations indicatinga direct celular damage at the physion. From the results, it is concluded that laserradiation should be on absolute contraindication during the phase of bone growth or in the inmatureskeleton.
