摘要： A mechanism for osteosynthesis 1 is provided that is capable of finely adjusting the amount of movement of a fractured bone, quantifying the amount of the movement and can be used both in pulling the fractured bones apart from each other and pulling the fractured bones nearer toward each other. A first mechanism for osteosynthesis 1 of the present invention comprises a plate part 2 for reducing two or more fractured bones monolithically by fixing at least both ends of the plate part 2 on the fractured bones and a sliding part 25 for moving one fractured bone along a sliding elongate hole 3 formed in the plate part 2 so as to elongate from the one fractured bone toward another fractured bone, the sliding part 25 comprising a rack 31 formed on an inner surface of the sliding elongate hole so as to extend along a sliding direction and a pin inserted in the sliding elongate hole 3, the pin 4 having a head portion 41 having a pinion for engaging with the rack 31 and a base portion 45 to be inserted into the one fractured bone, wherein the sliding part 25 moves the one fractured bone slidably along the sliding elongate hole 3 by rotating the pin 4.
