Summary: BACKGROUND: The stimulating effect of low level laser phototherapy on bone healing has been shown in a number of in vitro and animal studies. However, the effect of LLLT on the bone healing in human has not been previously wide demonstrated. The article reports an accidentally injury pattern and reported as fractures of the mid third of the left tibia.

OBJECTIVE: The purpose of this case study was to demonstrate the biological effects of low-level laser therapy (LLLT) on tibial  fractures treated surgically using radiographic, examinations.

CASE REPORT: The case hospitalized for conventional surgery and followed by applying Low Level Laser Therapy LLLT to enhance and accelerate the bone fracture healing of the left tibia using the effect of laser bio-stimulation. Radiological x-ray imaging evaluation follow up for our case showed a significant bone healing rate as result of exposure of Diode Laser 650 nm with energy density of 5 J/cm 2 three times/week for one month. Radiographic findings revealed no significant fracture callus thickness  difference before using LLLT however, the fractures showed significant callus formation after using LLLT.

CONCLUSION: The study suggests that LLLT accelerates the process of fracture repair or cause increases in callus volume.
