Fig. 4

Stress contour maps of the four plate groups in standing. A-C represent loading forces of 200 N, 400 N, and 600 N, respectively. A, D, G, and J represent the DLP, LACP, SQAP, and CORAP groups, respectively. In A-C, the left side represents the anterior column plate, and the right side represents the posterior column plate. In D-F, the left side represents the anterior column plate, and the right side represents the ilioischial plate. In J-L, the left side represents the reduction plate, and the right side represents the obtained plate. The red areas indicate high stress, while the blue areas indicate low stress.
