Abstract
This study examines 282 individual Abbreviated Injury Scale (AIS) 2 or greater injuries to the chest that occurred in a sample of United Kingdom side impact crashes. The injuries were all sustained by front seat occupants seated on the struck side. Crash characteristics such as collision severity, object struck and injury contact source that were associated with the injuries are examined. Overall, the study reinforces the view that reduction of injury severity should rely on controlling the magnitude and distribution of the impact forces applied to the thorax when it collides with the vehicle side structure, chiefly the door.
