Have you ever heard of a lion that could roar as loud as a loudspeaker, run as far as a train, cut as deeply as a power saw, or strike as powerfully as a wrecking ball? 你听过有狮子能吼得像喇叭一样大声，跑得像火车一样快，刺得像动力锯一样深，或者像重物滑车那么有冲力吗？
When removing a cortical graft from the outer table, first outline the area with an osteotome or power saw.Then peel the graft up by slight prying motions with a broad osteotome. 从髂骨外板切取皮质骨块时，先以骨凿或动力锯切割出取骨范围，然后再以宽骨凿轻撬取下骨块。
