The Mersey Region Trauma Survey was performed oner 12 months in 1989 and 1990 to study the epidemiology of trauma in a population of 3 200 000. All deaths from injuries, and all survivors with an injury severity score of 15 or over were included, giving a total of 1088 cases. This paper, primarily epidemiological, considers those victims with a pelvic fracture (153 patients), and especially those who reached hospital alive (111 patients). The epidemiology, hospital care and mortality are considered, hut the specific management of individual fractures is not. Copyright (C) 1996 Elsevier Science Ltd.
