Helium-neon laser therapy interferes with epiphyseal plate growth in the femur and tibia of rabbits

Abstract

The purpose of this study was to evaluate the influence of low-level laser therapy (LLLT) on epiphyseal cartilage in the femur and tibia of rabbits. A total of six male New Zealand rabbits were used in this study. The right tibia or femur lesions (control group) served as negative control and the left as experimental (laser) group. Helium-neon (HeNe) laser light with an energy density of 6 J/cm

“…Ribeiro et al [31] conducted a study with the aim to evaluate the influence of low-level laser therapy (LLLT) on epiphyseal cartilage in the femur and tibia of rabbits. They found that HeNe laser irradiation (632.8 nm, 6 J/cm 2 ) stimulates the cartilage ossification to bone, causing some delay in growth and development of the epiphyseal plate.…”
