Fig. 8From: Finite element analysis of different configurations of fully threaded cannulated screw in the treatment of unstable femoral neck fracturesDiagrams showing the maximum principal strains plotted in percent with a yield strain cut-off value of 0.9%. Orange and red regions are susceptible to yielding strains above 0.9% and have a risk of cut-out. a Triangular model. b Inverted triangular model. c Triangle with anterior single screw. d Triangle with posterior single screw. e Vertical modelBack to article page
