In contrast, locking plates follow the biomechanical principle of external fixators and do not require friction between the plate and bone.
与之相比，锁定钢板外固定架的生物力学原则相仿，无需钢板与骨之间的摩擦力。
Conclusions The design of external fixatures conforms to biomechanical principle. It is easily manipulated and is effective in clinic application.
结论该外固定器的设计符合生物力学原理，使用方便，临床应用效果满意。
