This study includes all polytrauma patients with chest injury treated between 1992 and 2002 at a major urban trauma center

332 out of 501 polytrauma patients, 228 males and 104 females, had a coexisting chest injury. Mean age at the time of injury was 37.7 years, and 258 patients were intubated before admission. Average period on ICU was 15.4 days, and 35.9 days for total hospital stay. Regarding the injury pattern in 143 patients a combined hemo-/pneumothorax was seen, 109 patients had either a hemothorax or a pneumothorax, in 155 patients a unilateral and in 52 patients a bilateral serial rib fracture was diagnosed, in 28 patients either sternal or singular rib fractures were determined, in a total of 23 patients an unstable thorax or a flail chest was seen, 105 patients had a unilateral pulmonary contusion, and in 79 patients a bilateral pulmonary contusion was diagnosed. Finally, a total of eleven patients with a traumatic aortic disruption were identified
