title: The role of associated injuries on outcome of blunt trauma patients sustaining pelvic fractures.
abstract: In order to identify the prognostic factors and to evaluate the impact of associated injuries in the outcome of patients with pelvic fractures, a retrospective review of the medical records of patients admitted with a pelvic fracture during a 42-month period was carried out. Demographic data, the mechanism of injury, the physiologic status on admission, associated injuries, pelvic fracture classification, complications and mortality were analysed. One hundred and three patients were included in the study. Fifty-nine were male, and the mean age was 34. The mean Revised Trauma Score (RTS) and Injury Severity Score (ISS) were 7.1 and 20, respectively. Pedestrian vs vehicle (59%), was the most frequent mechanism of injury. Twenty patients died (19%) most frequently due to "shock". Complications developed in 37 patients (36%), pneumonia being the most frequent. Age greater than 40 years (p=0.02), "shock" upon admission (p=0.002), a Glasgow Coma Scale (GCS)<9, Head AIS>2 (p<0. 001), Chest AIS>2 (p=0.007), and abdominal AIS>2 (p=0.03) all correlated with increased mortality. No correlation between pelvic fracture classification or fracture stability with mortality was observed. The outcome of patients with pelvic fractures due to blunt trauma correlates with the severity of associated injuries and physiological derangement on admission rather than with characteristics of or the type of fracture.
