Summary:Scoliosis is a disease of the deformation of the spine, and occurs in teenager of a few percentages. If the disease progresses are in severity, the surgical operation is necessary to correct the spine with pedicle screws and rods. The pain and burden of patient are large since a surgical operation for adjustment of the screws is necessary. To reduce them, the growing rod system that expands the spines using the ultrasonic vibration that is applied to the rod from the outer of the skin has been studied and developed. This paper investigates the primitive characteristics of the growing rod using biomaterial. And, the relation between the extension by applying a vibration and the forces for pull of the rod by the weight are considered using biomaterial. As a result, it is clear that there is the optimal force for extension efficiently.
