A penetrating injury, also called an open head injury, results when an object penetrates the skull and enters the brain. A perforating brain injury is a type of penetrating injury in which a high-velocity missile enters the brain and then exits it.
Causes of Penetrating Injury
Penetrating injury can be caused by high-velocity objects such as bullets, but can also be caused by low-velocity objects such as knives and other weapons. One of the most common causes of penetrating injury is skull fracture, in which a piece of bone from the skull penetrates the brain and causes damage to either the left brain function or the right brain function. Skull fractures can be caused by a blow to the head, car accidents, a fall, or a sports or athletic injury.
Prognosis of Penetrating Injury
As a general rule of thumb, high-velocity injuries are associated with more long-term damage than low-velocity injuries. Penetrating injuries from bullets, for example, have a mortality rate of 92%. Perforating injuries have a prognosis thatâ€™s even more grim.
Patients who live can expect to have issues related to the area of the brain thatâ€™s damaged. Approximately 50 percent of patients with penetrating injuries experience
