Selection of internal fixation method for femoral intertrochanteric fractures using a finite element method

Figure 6 Stress distribution and displacement distribution under different loading modes when lateral and medial defects were fixed with proximal femoral anti-rotation intramedullary nail steel wire and lateral wall protection plate. A: Von Mises stress distribution map when lateral and medial defects were fixed with proximal femoral anti-rotation intramedullary nail (PFNA), steel wire, and lateral wall protection plate; B: Displacement distribution when lateral and medial defects were fixed with PFNA, steel wire, and lateral wall protection plate.
