Objectives: Perform a systematic review for the most relevant pelvic injury research involving PMHS. The review begins with an
explanation of the pelvic anatomy and a general description of pelvic fracture patterns followed by the particular case of pelvic
fractures sustained in pedestrian-vehicle collisions. Field data documenting the vehicle, crash, and human risk factors for pedestrian
pelvic injuries are assessed.
Method: A summary of full-scale PMHS tests and subsystem lateral pelvic tests is provided with an interpretation of the most
significant findings for the most relevant studies.
Conclusions: Based on the mechanisms of pedestrian pelvic injury, force, acceleration, and velocity and compression have been
assessed as predictive variables by researchers although no consensus criterion exists.
Keywords: pelvis fractures, pedestrian crashes, PMHS
