The Effects of Phototherapy of an 808 nm Diode Laser on Bone Fracture

抄録

[Purpose] This study investigated the effects of low-level laser phototherapy on hand and forearm fractures. [Subjects and Methods] This was a one-group pretest-posttest design study. We recruited 9 patients with hand or forearm fracture, and they received diode laser treatment (808 nm, 10 Hz, 60 mW). Evaluation of pain on a visual analog scale (VAS) and radiographic assessments were made pre-intervention, post-intervention, and at two weeks of follow-up. [Results] There were significant differences in VAS scores between pre-intervention and post-intervention and between pre-intervention and 2 weeks of follow up. In the radiographic assessment, the percentage of detectable cortical bridging also increased significantly after phototherapy. [Conclusions] We consider that low-level laser phototherapy is effective for human bone healing and pain relief.
