摘 要：Degenerative articulate diseases, resulting from dysplasia and aseptic necrosis of the femoral head and neck, chronic dislocation of the femur and osteoarthrosis, are often treated surgically by an excision in the femoral head and neck. This procedure entails the formation of a false fibrous articulation, providing pain relief. The action of low level laser therapy (LLLT) has been described in orthopedic applications, to repair both bone and articular tissue. LLLT has demonstrated favorable results in vitro and in vivo in stimulating bone repair. A diode laser, 650 nm, with a potency of 30 mW, was used trans-surgically to irradiate. A diode laser (780 nm and the potency of 40 mW) was used on the skin for post-surgery applications. For the experiment, 10 clinically normal New Zealander rabbits underwent surgery and were then divided into two groups, one submitted to irradiation and the other kept for sham. Fifteen days after the surgery, samples of the newly formed tissue were collected from both groups, for macroscopic evaluation of the fibrous pseudo-articulation forming process on the irradiated and sham groups. The macroscopic and microscopic appearance of the samples, suggest that the utilization of the LLLT in the formation of fibrous pseudo-articulation was effective in accelerating the cicatrization process and in improving the quality of the formed tissue.
