AbstractA retrospective review of patients admitted with sternal fractures without massive trauma to the chest or hypotension was undertaken. Chest pain was present in 59 of 60 patients while external signs of bruising were noted in one-third. The standard anteroposterior (AP) roentgenogram of the chest was diagnostic in all patients. Thirty-four (56.7 per cent) patients had 51 significant noncardiac injuries, an average of 1.5 injuries per patient. Most commonly, these were orthopedic injuries, fractures of the rib and closed head injuries. Sixty-two per cent of the patients with sternal fractures had abnormal electrocardiograms (ECG) at some time, of which 34 per cent had ECG changes consistent with ischemia. The admission ECG was normal in 20 (48 per cent) patients. Three of these patients subsequently had significant ECG changes. Fractures that were comminuted or involved the sternal angle were more likely to be associated with ECG abnormalities than were simple fractures of the sternal body. Only three patients had elevated creatine phosphokinase-myocardial bond fractions. Two dimensional echocardiography and biventricular radionuclide angiocardiography were normal in 11 patients, including five patients with ECG abnormalities. There were no deaths related to the sternal fractures per se or to associated injuries. Sternal fractures result from high energy trauma and should be suspected in patients with chest pain after blunt thoracic trauma. The lateral roentgenogram of the chest is the most useful diagnostic test. There is a high incidence of associated cardiac and noncardiac injuries in these patients mandating close observation with ECG monitoring in the intensive care unit.
