Ideal Configuration Distribution of Femoral Neck Cannulated Screw in High Altitude Population: A Finite Element Study

Figure 5

The displacement nephogram of cannulated screws under loads of 500 N in two models. Red is the maximum displacement upward and blue is the maximum displacement downward. (a). Oblique triangle screw placement in complete femoral neck model. (b). Equilateral triangle screw placement in complete femoral neck model. (c). Oblique triangle screw placement in femoral neck fracture model. (d). Equilateral triangle screw placement in femoral neck fracture model.
