Slide die sabikarupureto due to this invention the bone fixed screw (3) to prevent vertical motion, at the same time in order the fixed screw (3), the boa which corresponds to be able to be introduced in (4), in order with 1st direction deformation possible 1st vertical cutoff means (71) and, already one fixed screw (3), already to be able to be installed by one boa (4) elastic, elastically deformation possible 2nd vertical cutoff means (8) and the back out prevention device which consists of to have (2) with the 2-way to differ from 1st direction, aforementioned as for 1st and 2nd cutoff means, verticalityDirection, at the same time turns to clockwise direction outside it is combined the load being added to the fixed screw, when (3), it has reached the point where it becomes deformed elastically.本発明によるスライド型サービカルプレートは、骨固定ネジ(3)の垂直運動を防止し、かつ固定ネジ(3)が、対応するボア(4)に導入され得るように第1方向で弾性的に変形可能な第1垂直遮断手段(71)と、もう1つの固定ネジ(3)が、もう1つのボア(4)に装着され得るように第1方向と異なる第2方向で弾性的に変形可能な第2垂直遮断手段(8)とからなるバックアウト防止装置(2)を備え、前記第1及び第2遮断手段は、垂直方向の、かつ時計回りの方向に回転する組み合わされた外部荷重が固定ネジ(3)に加えられる時、弾性的に変形するようになっている。
