The Variable Angle Hip Fracture Nail Relative to the Gamma 3: A Finite Element Analysis Illustrating the Same Stiffness and Fatigue Characteristics

Figure 4

Force displacement curve of the VAN at 120°, 130°, and 140° and the Gamma 3 at 120° and 130° lag-screw-to-nail angles. The initial stiffness values were VAN 120°, 340 N/mm; VAN 130°, 310 N/mm; VAN 140°, 280 N/mm; Gamma 3 120°, 350 N/mm; Gamma 3 130°; 270 N/mm.
