Head trauma refers to any damage to the scalp, skull or brain caused by injury. Head injury may be classified in various different ways according to the type of injury, which structures in the head are damaged or how severe the trauma is.
Closed or Open Injury
One way head injuries are classified is according to whether the injury is open or closed.
An open injury refers to damage that penetrates the skull causing problems such as bleeding in the brain, skull fracture or the pressing of bones against structures in the brain. This type of injury is more likely to occur when a person is moving at high speed, when colliding with a windscreen during a car accident, for example. A gunshot to the head would be another example.
A closed injury refers to damage that does not break the skull or penetrate the brain tissue. Although the skull is not broken, this type of injury can still cause brain damage in the form of swelling or bruising.
