Crash reconstruction techniques were used to estimate the acceleration of the head in 17 cases. These accelerations were correlated with the severity and distribution of brain injury as determined by neuropathological and/or radiological examination. Estimated linear accelerations ranged from 1000 m/s2 to 6600 m/s2. There was a positive association between linear acceleration and the extent of haemorrhagic brain injury, in lateral, but not frontal, impacts to the head. The estimated angular accelerations ranged from 6000 rad/s2 to 50,000 rad/s2 and showed a similar positive association with the extent of brain injury in lateral impacts. For the entire group of cases there were 15 frontal impacts to the head, 7 lateral impacts, three occipital impacts and in one case the location impact was not known. Lateral impacts were more likely to be associated with death than were frontal impacts at similar levels of acceleration. | Publisher | International Research Council on the Biomechanics of Injury | Publisher City | Zurich | Conference Name | 1991 International IRCOBI Conference on the Biomechanics of Impacts | Conference Abbreviation | IRCOBI | Conference Location | Berlin, Germany | Conference Date | 11-13 September 1991 | Page Count | 12 | Notes | available from CASR library on request |
