Femoral fracture is trauma with high mortality rate. Incidence of femoral fractures in America is approximately 13 cases per 100,000 people per year. In Indonesia, it is reported that the incidence of fractures every year is 11.10 cases per 1,000 people per year, with an incidence of 11.67 cases per 1,000 people per year in men and 10.65 cases per 1,000 people per year in women. Long bone fracture cases frequently related to missing bone segments, that can disrupted the bone healing. Incidence of long bone fracture with defect reported about 13,9%. The process of defect fracture healing requires internal and external mechanical stimulation, external stimulation can be stimulated using low-intensity pulsed ultrasounds. The positive effects of ultrasound therapy (LIPUS) on accelerating bone healing have been demonstrated in several studies. Clinical studies have shown a significant positive effect from LIPUS in the treatment of non-union fractures and accelerated fracture repair compared to fractures treated with placebo of 38%. The purpose of this study was to determine the effectiveness of LIPUS on healing of defect femoral fractures in rabbit post ORIF plate and screw based on radiological measurements. This study is a comparative, unpaired laboratory experimental study with two treatment groups and one control group. Treatment group consist of group I that was given LIPUS 30 mW/cm2 for 10 minutes per day and Group II 30 mW/cm2 for 20 minutes per day, Group III without LIPUS treatment as control group. Radiological assessment was performed to assess callus formation based on the Tiedemann score. After that data is collected, data editing, coding, entry were carried out and analyzed statistically. There were significant differences between treatment group and control group towards callus diameter formation, between group I, II and control with mean of Tiedemann in each group 97.76; 169.83; 76.88; with p value < 0.05. LIPUS can enhance fracture healing in rabbit femur defect based on radiography measurement.
