To determine the medical findings that might be expected in the 1 million persons injured by automobile accidents each year, 1,000 injury-producing accidents were carefully studied. Of the 2,253 occupants involved in the thousand accidents, 1,678 (74.5%) were injured to some degree. Of those persons receiving an injury, only half could be diagnosed as of a minor degree. When considering body distribution, injuries to the head alone were the most frequent, followed by injuries with a combination of head and lower extremity involvement. Almost two-thirds of the injuries involved more than one body area, emphasizing the need for an extremely careful physical examination so as not to overlook concealed wounds. The practicing physician can profit greatly by knowing the representative picture resulting from automobile accidents.
