Comparison of four kinds of internal fixation for acetabular fracture of the lower anterior column: a finite element analysis

Objective To compare the biomechanical stability of 4 internal fixations in treatment of acetabular fracture of the lower anterior column through finite element analysis. Methods One normal adult male pelvis was subjected to 0. 7mm thin-section CT scanning and 379 CT pictures were obtained. Finite element modeling software was used to establish internal fixation models for acetabular fracture of the lower anterior column, including lag...
