Abstract

Measures for an optimized protection in lateral collisions are pregnant in current car developments. For this it is important to know the injury risks and mechanisms in lateral collisions.

A review of literature head, thorax and pelvis are the most injured body regions in frequency and severity. The problem of pelvic injuries is the complexity of bony structure and the different kind of fractures relating to various possibilities of traumatological treatment.

In this study 1,556 seated occupants in isolated lateral collision were analyzed. 35 persons suffered pelvic fractures and 13 occupants femural fractures. The paper will describe the biomechanics of pelvic fractures including the biomechanics of femur as part of pelvic load in relation to delta-v, intrusion and vehicle deformation characteristics. The lateral deformation was measured and characteristics reproducted in a 3-dimensional view correlating to the injunes.
