Abstract
A bone screw includes a front portion, a rear portion, and a shaft portion. The shaft portion is fixedly joined to the front portion and the rear portion, so as to form an integral bone screw. The Young's modulus of the shaft portion is smaller than that of the front portion and that of the rear portion.
