Atlanto-Occipital Fracture Dislocation in Lap-Belt Restrained Children

摘要

This paper discusses an attempt to relate measured loading at the head neck junction of are strained six year old ATD during a frontal crash, to the mechanism of upper cervical fracture dislocation in young children. Lap belt, lap shoulder belt and a four point restraint system are considered. The basis for the reconstructions is the fatal injury to lap-belt restrained young children seated in the rear seat of contemporary minivans. The study concludes that simple forces and bending moments measured on such an ATD may not provide a sufficient basis for judging the likelihood of such an injury. Suggestions for a more comprehensive injury analysis are made.
