Objectives: The angled blade plate has been the historical standard in fixed-angle extramedullary subtrochanteric femur fracture fixation, but it requires an extensile lateral approach to the femur.
目的：过去采用角钢板髓外固定作为股骨转子下骨折标准方法，但需要较长的外侧切口到达股骨。

Effects of mechanical heterogeneity on fracture toughness and crack deviation Angle of the joints were investigated by experiment.
通过试验研究了力学不均匀性对接头断裂韧性和裂纹开裂角的影响。
