Update of the WorldSID 50th Male Pelvic Injury Criterion and Risk Curve
Studies were published in 2015 (Petit et al.) and 2016 (Lebarbé et al.) where the injury mechanism and threshold of the sacroiliac joint were investigated in two slightly oblique crash test conditions from 18 Post Mortem Human Subjects tests. It concluded that the sacroiliac joint fractures were associated with pubic rami fractures. These latter being reported to occur first in the time history. Therefore it was recommended not to define a criterion specific for the sacro-iliac joint. In 2012, injury risk curves were published for the WorldSID dummy (Petitjean et al.). For the pelvis, dummy and PMHS paired tests from six configurations were used (n=55). All of these configurations were pure lateral impacts. In addition, the sacro-iliac joint and femur neck load were not recorded, and the dummy used was the first production version (WorldSID revision 1). Since that time, the WorldSID was updated several times, including changes in the pelvis area.
