title: Analysis of fatal injuries to motorcyclists by helmet type.
abstract: To clarify the characteristics of injuries of motorcyclists dying in accidents in relation to helmet type, we retrospectively analyzed forensic autopsies of 36 helmeted motorcycle riders. The presence of major injuries and injury severity were evaluated with the injury severity score and the 1990 revision of the Abbreviated Injury Scale. Persons with open-face helmets (19 cases) were significantly more likely to have sustained severe head and neck injuries, especially brain contusions, than were persons with full-face helmets (17 cases). Furthermore, major injuries of the chest or abdomen, rib fractures, lung injuries, and liver injuries were each present in more than one quarter of all cases (26.3% to 70.6%), but their prevalences did not differ significantly between riders with different types of helmet. Because many types of head and neck injuries cannot be prevented and fatal chest and abdominal injuries occur despite the use of full-face helmets, more effective helmets and devices for protecting the chest and abdomen are needed to decrease deaths from motorcycle accidents.
