PURPOSE: A broken bone fixing device using the elasticity of a wire is provided to stably fix a bone by inserting a center shaft and an elastic wire into the medullary cavity of the bone and twisting the wire so as to induce a line contact in the medullary cavity. CONSTITUTION: A broken bone fixing device(100) comprises a center shaft(105), first and second elastic wires(111,112), an external guide unit(115), a rotating body(120), and a fixing nut(125). The center shaft has one side from which a first screw is protruded in a predetermined length. The first and the second elastic wires are arranged in the vicinity of an outer surface of the center shaft. The external guide unit has an inner surface on which a second screw corresponding to the first screw is formed. The external guide unit is connected to the center shaft in such a manner that the external guide unit is attachable/detachable to/from the center shaft. The rotating body is coupled to a lower portion of the external guide unit, and rotates the first and second wires. The fixing nut is coupled to the center shaft through the first screw during removal of the external guide unit, and fixes the rotating body.
