Results of biomechanical testing. a Initial axial stiffness (IAS): The locking plate fixation (LPF) group showed significant differences compared with the LPF-AO cancellous lag screw (AOCLS) and LPF-combined cancellous lag screw (CCLS) groups (p < 0.05); b Maximal axial micromotion of the lateral fragment (MAM-LF) in cyclic compression loading in every 1000 cycles: MAM-LF in the LPF group showed significant differences compared with that in the LPF-AOCLS and LPF-CCLS groups measured at every 1000 cycles (p < 0.05); c Failure load in the load-to-failure test: There was a significant difference in failure load when the LPF group was compared with the LPF-AOCLS and LPF-CCLS groups (p < 0.05). *p value < 0.05
