Abstract

Pelvic fractures are complex, debilitating injuries associated with high mortality rates and a significant female sex-bias. Computational and experimental techniques have been utilized to evaluate the mechanical response of the pelvis, which have lead to fundamental information about pelvic fracture susceptibility. However, further understanding of the mechanism of pelvic fractures is needed. Therefore, a finite element (FE) model using a combination of 2D and 3D elements is presented for the mechanical evaluation of the pelvis. Once developed, the 2D/3D modeling approach was used to create a hemipelvis model, which was then validated using mechanical experiments conducted on a composite hemipelvis. The force-displacement measurements from the experiments and the FE model correlate well. Moreover, there was reasonable agreement between the principal strains measured by the strain gauges during experiments compared to FE results. In conclusion, this modeling approach could potentially be used to model human pelves to study pelvic fractures.
