Abstract
Distraction osteogenesis (D. O) is one of the promising bone lengthening technique. After osteotomy, the callus will change from soft bone to hard bone with healing time. Usually operated bone situation is diagnosed by X-ray photograph. However, it is difficult to know the detail condition of distracted bone only by X-ray procedure. In this study, a new method to detect bone situation with measuring vibration was developed. Theoretical analysis of the bending vibration of distracted bone and animal experiment in the rabbit tibia were carried out. The natural frequencies of tibia's bending vibration were measured for four weeks by accelerometer. The results indicate that the natural frequency can be good index of the healing in distracted bone.
