The maximum sum displacement of the pelvic ring (${\mathit{U}}_{\mathbf{max}}^{\mathit{R}}$) and the maximum vertical displacement of the injured sacrum (${\mathit{Z}}_{\mathbf{max}}^{\mathit{S}}$), the maximum von Mises stress of internal fixator (${\mathit{\sigma }}_{\mathbf{max}}^{\mathit{F}}$) and the maximum von Mises stress of bony tissue of pelvic ring (${\mathit{\sigma }}_{\mathbf{max}}^{\mathit{B}}$) of two groups of surgical FE models (PTMP vs. SIJS) under lateral bending states.
