Head injury remains a serious public health problem occurring at a rate of 150 per 100,000 population per year in the United States. The most current data indicates that head injury accounts for over 20,000 deaths and 50,000 permanent disabilities each year (1,2). With an understanding of the mechanisms of secondary injury and development of appropriate treatment strategies, there has been a significant decline in head injury mortality over the past two decades. Indeed, contemporary multicenter studies are reporting mortality rates as low as 17% (3) (Figure 1).
