[Management of isolated sternum fracture: screening for heart contusion with troponin T].

Abstract

In all of our reported cases a seat belt injury was the reason for the sternal fracture. Only 4 of 27 patients of this prospective study suffered from a heart contusion. None of our patients showed complications. An isolated sternal fracture with or without heart contusion seems to be of minor clinical significance. Referring to our patients a screening of a heart contusion with CKMB/CK activity and ECG seems to be sufficient when the trauma is not older than 12 hours. The longer persisting plasma concentrations of cardiac troponin T (cTnT) enables a diagnosis of a heart contusion even after a few days.
