The records of 92 patients with flail chest injury treated at a Level I trauma center were analyzed retrospectively. Associated intrathoracic injuries included pulmonary contusion (46 percent) and pneumothorax or hemothorax, or both (70 percent). The incidence of great vessel, tracheobronchial and diaphragmatic injuries was no different from that of a control population with simple rib fractures. ⋯ Flail chest does not seem to be a marker for great vessel, tracheobronchial, or diaphragmatic injuries. The majority of patients (more than two-thirds) will require mechanical ventilation for prolonged periods. Of paramount importance is the recognition of flail chest as a marker of high kinetic energy absorption, resulting in life-threatening thoracic as well as nonthoracic injuries.
