Penetrating injuries most often result from gunshot or knife wounds, and the site of entry is usually obvious. Nonpenetrating injuries most often occur during motor vehicle accidents, either from rapid deceleration or from impact of the chest against the steering wheel; the former may be associated with significant cardiac injury even in the absence of external signs of thoracic trauma.
