Abstract

PURPOSE: To facilitate the joining of broken parts by arranging a first mounting member and a second mounting member each to be applied to bones and a coupling member to be screwed downed on the first mounting member with a left-handed screw while being screwed down on the second mounting member with a right-handed screw.
CONSTITUTION: A tip part A of a mounting member 1 is mounted on one hand of one bone to be joined while a tip pat B of a mounting member 2 is mounted on the other bone, and a coupling member 3 is turned to a direction of the arrow 7 so that a desired interval is kept between the tip part A of the mounting member 1 and the tip part B of the mounting member 2. Both the bones can be drawn back by turning the coupling member 3 to a direction to lessen the interval of the tip parts A and B, thereby allowing the joining of the bones at a broken point. To mounting the mounting members 1 and 2 on the bones, holes H1 and H2 are made on both the bones to be put together with a diameter and a depth enough to insert the tip parts A and B of the respective members, and then, the tip parts A and B are inserted into the holes H1 and H2.
