Penetrating trauma is an open wound injury that occurs when an object pierces the skin and enters a tissue of the body, creating a deep but relatively narrow entry wound. In contrast, a blunt or non-penetrating trauma may have some deep damage, but the overlying skin is not necessarily broken and the wound is still closed to the outside ...
A penetrating head injury, or open head injury, is a head injury in which the dura mater, the outer layer of the meninges, is breached. [1] Penetrating injury can be caused by high- velocity projectiles or objects of lower velocity such as knives, or bone fragments from a skull fracture that are driven into the brain.
A rapid trauma assessment goes from head to toe to find these life threats: [1] [3] [5] Cervical spinal injury; Level of consciousness; Skull fractures, crepitus, and signs of brain injury; Airway problems (although these were checked during the initial assessment, they are rechecked during the rapid trauma assessment) such as tracheal deviation
Head injury may be associated with a neck injury. Bruises on the back or neck, neck pain, or pain radiating to the arms are signs of cervical spine injury and merit spinal immobilization via application of a cervical collar and possibly a longboard. If the neurological exam is normal this is reassuring.
Closed-head injury is a type of traumatic brain injury in which the skull and dura mater remain intact. Closed-head injuries are the leading cause of death in children under 4 years old and the most common cause of physical disability and cognitive impairment in young people.
Mechanism-related classification divides TBI into closed and penetrating head injury. [10] A closed (also called nonpenetrating, or blunt) [14] injury occurs when the brain is not exposed. [15] A penetrating, or open, head injury occurs when an object pierces the skull and breaches the dura mater, the outermost membrane surrounding the brain. [15]

They may cause substantial internal bleeding or secondary injuries, such as a collapsed lung, which may not be readily evident during primary assessment. Occasionally, the object causing the injury remains in the wound as an impaled object. A stab wound from a knife or other sharp object, or a bullet wound, are examples of this type of injury.
