Abstract

Postmortem and crash investigation reports were examined for 35 cases of belted automotive crash fatalities. This paper highlights those cases with speculation of the injury mechanism in the post mortem report. In two cases, the medical examiner made specific reference to a 'whiplash' mechanism of brain injury, which refers to an inertial loading of the neck without head contact. Examination of the car interior in one case indicated evidence of head contact with transfer of hair, and the other facial contact with transfer of teeth. Death was more likely due to direct head impact. In another case, the vehicle was struck laterally by another car on the far side of the driver. The medical examiner stated that the driver incurred typical 'steering wheel type' injury, while examination of the car interior indicated no consequential contact between the driver and the steering wheel. Instead, the intruding passenger door probably impacted the driver at a velocity high enough to induce fatal chest injuries. These cases demonstrate the necessity of a thorough examination of contact points in the crashed car to discern the mechanism of injury and to reconstruct the kinematics of injured occupants in a crash. They also demonstrate how 'popular' misunderstanding of mechanisms of fatal injury may be introduced and perpetuated.
