Abstract
A fixing tool used in a ligament reconstruction operation includes a fixing member having a main body part provided with a through-hole and two spike parts which can be stricken into the bone and a fixing screw. The fixing screw includes a shaft part having a self-tap portion and a male screw portion, a head part, and a lumen. The fixing screw can be screwed into the bone plug in a state where a guide pin pierced into the bone plug penetrates the lumen of the fixing screw and a pulling member mounted to the bone plug and extended from the bone tunnel is being pulled. The fixing screw can adjust a tensile force of the tendon graft by adjusting the amount of screwing of the fixing screw into the bone plug after the head part of the fixing screw contacts the fixing member.
