PROBLEM TO BE SOLVED: To provide an osteosynthesis screw fixing member which is crushed evenly when inserting an osteosynthesis screw into the fixing member and fills a sufficient amount of granules of an equal and appropriate size into between the bone and the screw, thereby stably fixing the screw and which is in form to be easily worked and handled.SOLUTION: The osteosynthesis screw fixing member comprises a columnar body having an insertion surface 12 for inserting a screw on one surface and having an axis 15 in a longitudinal direction which is the insertion direction of the screw. In the osteosynthesis screw fixing member, a plurality of through-holes 11 having an opening 11a on the side peripheral surface of the columnar body, passing through the axis 15 and penetrating in a short direction vertical to the longitudinal direction of the columnar body are formed at a prescribed interval D in the longitudinal direction. The adjacent through-holes are each formed so as to be shifted from each other by 30-90° around the axis with the axis 15 as a center, and a guide groove 13 for inserting the screw into the axis 15 is provided on the insertion surface 12.COPYRIGHT: (C)2013,JPO&INPIT【課題】骨接合術スクリュー挿入時に均等に破砕され、骨と前記スクリューとの間に均等かつ適度なサイズの顆粒を十分な量で充填することにより、スクリューをより安定的に固定することができ、かつ、加工及び取扱いが容易な形態である骨接合術スクリュー固定部材を提供する。【解決手段】一の面にスクリューを挿入する挿入面12を有し、かつ、前記スクリューの挿入方向である長手方向に軸心15を有する柱状体からなる骨接合術スクリュー固定部材において、前記柱状体の側周面に開口部11aを有し、軸心15を通って、該柱状体の長手方向に垂直な短手方向に貫通する貫通孔11を、前記長手方向に所定の間隔Dで複数形成され、隣接する貫通孔11は、それぞれ互いに、軸心15を中心として軸心周りに30~90°ずれるように形成し、挿入面12に、スクリューを軸心15へ挿入するためのガイド溝13を設けた構成とする。【選択図】図1
