This study was performed to identify the effect of constant direct current and to give us methods which can be applied easily in clinic. Six rabbits was used at this experiment. After each animal was fractured at left fibula, divided into experimental group(n=3) and central group(n=3). Experiment duration of electrical stimulation on experimental rabbits was 35 days. Direct current from fifteen microampere to twenty microampere was passed continously through the placed electrode between fracture area and thigh. Negative electrode was placed at fracture area and positive at thigh. Roentgenography was used to observe bone-healing progression wet three times-at 15days, 25days and 35days after electrical stimulation. The results obtained are as followings: 1. Both experimental group and control group do not obtain callus formation on the first roentgenography(15 days after ES). 2. On the second roentgenography(25 days after ES), experimental group achieves above 70% on fracture-healing, but control group achieves about 20-30% on fracture healing. 3. On the third roentgenegraphy(35 nays after ES), experimental group achieves above 85-95% on fracture healing and control group achieves about 60-70% of bone union. Thus, statistically significance(independent t-test) was occured ie the second and third roentgenography between experimental group and control group.
