 This study examined the characteristics of trauma caused by traffic accidents in a large urban area. It found that the most common types of trauma were to the head, chest, and extremities, with the majority of patients surviving these injuries. Patients who died from their injuries more often suffered from head injuries, followed by thoracic and abdominal injuries. This suggests that head injuries are the most serious type of injury caused by traffic accidents in this setting. This article was authored by S. O. Grief, V. A. Kushner, and O. S. Siloviev.
