Reconstruction of type II+III pelvic resection with a modular hemipelvic endoprosthesis: a finite element analysis study.

Objective: To conduct a biomechanical study of the whole reconstructed pelvic ring using a modular hemipelvic endoprosthesis.

Methods: A subject-specific finite-element (FE) model of the whole pelvic ring, including the pelvis, sacrum and main ligaments, was constructed. Type II+III pelvic resection was simulated on the FE model.
