ある。Further, in FIG. 3(C), one mounting member 12 is constructed by fixing a member 14 curved in a substantially semicircular or semielliptical shape to the tip of a straight rod 13. Holes are formed at both ends of the member 14. In this case, to attach the attachment member 12 to the bone, a through hole is made in the bone and the bolt 15 is passed through it as shown in the figure, and the nut 1 is inserted.
This is done by stopping at 6. This attachment method is the same as the conventional one, but it can firmly connect and fix the bones, so it is very useful when it is necessary to firmly fix the bones and there is no problem with making a through hole. It is effective for

By simply rotating the joint member, the distance between the distal ends of the two attachment members can be adjusted to any desired distance, thereby allowing bones to be joined easily.
従って骨折部が仮関節の状態になることを有効に防止す
ることができる。また、継手部材の回転はスパナにより
容易に行うことができる。Therefore, it is possible to effectively prevent the fracture from becoming a pseudoarthrosis. Further, the joint member can be easily rotated using a spanner.
また、本発明においては装着部材として略し字状のもの
を使用した場合には、従来のように骨に貫通孔を開ける
必要はなく、装着部材の先端部が挿入できる程度の小孔
