Fig. 4From: Mechanical simulation study of postoperative displacement of trochanteric fractures using the finite element methodMaximum value view of the von Mises stress distribution (the medial femoral neck cortex). The upper section shows the non-displaced two-fragment fracture model and type A models. The lower section shows the non-displaced two-fragment fracture model and type B models. The black arrow indicates the maximum stress value at the medial femoral neck cortexBack to article page
