Abstract: A fixing tool used in a ligament reconstruction operation to fix a tendon graft having a bone plug can be inserted into a bone tunnel formed at a bone. The fixing tool includes a fixing member having a main body part provided with a through-hole and two spike parts which extend almost parallelly and can be stricken into the bone and a fixing screw including 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 is penetrated through 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 be adjusted a tensile force of the tendon graft by adjusting an amount of screwing of the fixing screw into the bone plug after the head part of the fixing screw contacts to the fixing member.

Abstract: A ligament graft-fixing apparatus has a rod-shaped shaft and a ligament graft-fixing unit that can be removably mounted on the rod-shaped shaft. The ligament graft-fixing unit has a screw part which drills a bone to form a tunnel therein to hold the ligament graft-fixing unit in the bone tunnel; a ligament graft-holding part; and a mounting tunnel in which the rod-shaped shaft is mounted. The mounting tunnel and the rod-shaped shaft have a torque transmission mechanism which transmits a rotational force imparted to the rod-shaped shaft to the ligament graft-fixing unit; and a removal prevention mechanism which holds the ligament graft-fixing unit on the rod-shaped shaft.

Abstract: A dilator (1) for reconstructing an anterior cruciate ligament, comprising a tip part (4) having two through-holes (2) and (3) arranged in juxtaposition and parallel with each other, a body part (5), and a rear end part (8) having two through-holes (6) and (7) arranged in juxtaposition and coaxially with the two through-holes (2) and (3), respectively. The tip part (4) and the body part (5) are formed in uniform generally elongated shapes in cross section longer in the arranged direction of the through-holes (2) and (3) so that a flat tunnel can be formed by striking the instrument from the rear end part (8) thereof to drive the tip part (4) and the body part (5) into an articular bone part. Thus, the anterior cruciate ligament can be reconstructed to a more tough ligament similar to a normal one in a shorter time.

Abstract: A ligament graft-securing device includes a body part; a knotting hole for knotting therein threads sewed to an end of the ligament graft and which is formed at one end of the body part; a through-hole for securing a tensile force-applying thread thereto and which is formed at the other end of the body part; spikes for temporarily fixing the ligament graft-securing device to a bone and which projects from one surface of the body part; and a screw securing hole for securing the ligament graft-securing device to the bone and which is formed on the body part.
