Box plot showing the maximum fracture forces (a) and stiffness (b) of the five fixation types. Post-hoc pairwise comparisons were conducted using Tukey’s test; the same letters indicate that means were not significantly different at the 0.05 level. LP_D, locking plate with four locking bicortical screws on the dorsal side; LP_L, locking plate with four locking bicortical screws on the lateral side; RP_D, regular plate with four regular bicortical screws on the dorsal side; RP_L, regular plate with four regular bicortical screws on the lateral side; KW, two K-wires
