Finite element analysis showing fracture displacement, and analyzing the stress applied on the plate as well as the stress on the screws in group PC: fracture displacement (A), stress applied on the plate (B), and stress applied on the screws (C); graphical representation of the results on histogram:comparison of fracture displacement in the three groups (D), comparison of three groups of plates subjected to maximum stress (E) ,comparison of maximum stress on three sets of screws (F). Note w = whole plateau was loaded, p = posterior plateau was loaded
