Fracture of the sternum in motor vehicle accidents and its association with mediastinal injury.

Abstract

Sternal fractures occurred in 78 out of 2097 consecutive victims of road traffic accidents who required to attend hospital; an incidence of 3.7 per cent. They were most common in restrained, front seat vehicle occupants involved in frontal collisions, and their frequency increased with age. There was a positive association with visceral chest injury but the latter was not thought to be the cause of death in any individual. Follow-up of survivors 2-4 years later revealed potential cardiac sequelae in 6 per cent.
