The Finite Element Method (FEM) can be used to analyze very complex geometr
ies, such as the pelvis, and complicated constitutive behaviors, such as th
e heterogeneous, nonlinear and anisotropic behavior of bone tissue or the n
oncompression, nonbending character of ligaments. Here, FEM was used to sim
ulate the mechanical ability of several method for each individual treatmen
t. The stability of open-book fractures with external external and internal
fixations that stabilize pelvic ring disruptions. A customized pelvic frac
ture analysis was performed by computer simulation to determine the best fi
xation fixations at either the iliac crests or the pelvic equator was simil
ar, and increased greatly when they were used in combination. However, exte
rnal fixations did not effectively stabilize rotationally and vertically un
stable fractures. Adequate stabilization was only achieved using an interna
l pubis fixation with two sacroiliac screws. [S0148-0731(00)00905-5].
