Abstract
IntroductionThe numbers of two-wheel vehicles are growing across the world. In comparison to other vehicles, motorcycles are cheaper and thus represent a significant part of the automobile market. Both the mobility and speed are attractive factors to those who want to use them for work or leisure. Crashes involving motorcyclists have become an important issue, especially fatal ones. Specific severe injuries are responsible for the deaths. Defining them is necessary in order to offer better prevention and a more suitable medical approach.MethodsAll fatal motorcycle crashes between January 2001 and December 2009 in Campinas, Brazil, were analyzed in this study. Official data have been collected from police incident reports, hospitals’ registers and autopsies. Both incidents and casualties were analyzed according to relevant variables. The Injury Severity Score (ISS) was calculated, describing the most potentially fatal injuries.ResultsThere were 479 deaths; 90.8% were male; the mean age was 27.8 (range 0-73); 86.4% were conductors of the vehicles; blood alcohol was positive in 42.3%; 49.7% died at a hospital; 32.6% died at the scene; 26.1% of the accidents occurred at night, 69.1% were urban and 30.9% occurred on highways. The main causes of injury were collisions (63%) and falls (14%). The mean ISS was 38.5 (range 9-75). With regard to injuries, head trauma (67%) and thoracic trauma (40%) were the most common, followed by abdominal trauma (35%). Traumatic brain injury (67%) and hypovolemic shock (38%) were the most frequent causes of death.ConclusionsAlcohol was a significant factor in relation to the accidents. Head trauma was the most frequent and severe injury. Half of the victims died before receiving adequate medical attention, suggesting that prevention programs and laws should be implemented and applied in order to save future lives.

Summary
In comparison to other vehicles, motorcycles are cheaper and represent a significant part of the automobile market Both the mobility and speed are attractive factors to those who want to use them for work or leisure. A World Health Organization (WHO) study on the Americas concluded that in countries like Brazil, Mexico, Canada and the United States [1], motorcycle crashes are responsible for 20-30% of all deaths due to trauma. Despite a few studies demonstrating the enormous impact in mortality of motorcycle crashes, this issue has been mostly neglected by scholars, the public and registries, and the extent deaths due to motorcycle accidents occur in Brazil remains unknown [11,12,13]
