A head injury is any trauma that leads to injury of the scalp, skull, or brain. These injuries can range from a minor bump on the skull to a devastating brain injury. Head injury can be classified as either closed or penetrating. In a closed head injury, the head sustains a blunt force by striking against an object. A concussion is a type of closed head injury that involves the brain. In a penetrating head injury, an object breaks through the skull and enters the brain. (This object is usually moving at a high speed like a windshield or another part of a motor vehicle.)
