摘　　要：目的:探讨锁定钢板的骨折区钉孔保护对预防钢板断裂的意义;方法:通过ANSYS软件建模,建立2种股骨远端骨折锁定钢板固定模型,骨折区1种有螺钉固定,1种无螺钉固定,计算2种模型的钢板、螺钉应力;结果:2种模型中,骨折区有螺钉固定的钢板应力明显减少;结论:运用锁定钢板治疗股骨远端骨折,建议钢板的骨折区置钉固定,对骨折和钢板保护有利。Objective：To investigate the significance of protecting the screw holes in prevention of plate broken. Method：Two kinds of locking plate fixation model of distal femoral fracture were established through ANSYS software. One has screw fixation in frac- ture area and the other has not. Then the stress of plate and screw was calculated in two models. Results：The stress of plate with screw fixation in fracture area reduced significantly than that of other one. Conclusions：Screw fixation in fracture area is favorable for protecting plate and fracture in the treatment of distal femoral fractures with locking plate.
