With the development of high-speed press on speeding up and lightweighting, it causes the augmentation of inertia force and component's flexibility. 随着高速压力机向高速化及轻量化方向发展,导致了惯性力的增大及部件柔度的增大。
The mechanism of pedicle screw augmentation with BG was that the BG could induce growth of the bone around the screw, improve the bone structure of screw - bone interface, and enhance the holding force of the interface vs. the screw. BG强化椎弓根螺钉稳定的机制是通过促进螺钉周围骨质生长,改善螺钉-骨界面骨质结构,提高界面对螺钉的把持作用而实现的。
