Study Analyzes Skull Protection by Bicycle Helmets

Bicycle accidents are a common cause of traumatic injury in the United States. The most recent statistics indicate that there were an estimated 500,000 bicycle-related injuries treated in U.S. hospital emergency rooms in 2004. Of those, 69,500 were head injuries, and of the 600 bicycle-related deaths, about two thirds were attributed to traumatic brain injury (TBI).
