While impact on the brain at the same site of injury to the skull is the coup effect. If the impact causes the head to move, the injury may be worsened, because the brain may ricochet inside the skull causing additional impacts, or the brain may stay relatively still (due to inertia) but be hit by the moving skull (both are contrecoup injuries).
[15] [66] To date, the VA-BU-CLF Brain Bank is the largest CTE tissue repository in the world, with over 1000 brain donors.

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.
Traumatic brain injury is defined as damage to the brain resulting from external mechanical force, such as rapid acceleration or deceleration, impact, blast waves, or penetration by a projectile. [10] Brain function is temporarily or permanently impaired and structural damage may or may not be detectable with current technology. [11]
Traumatic brain injury (TBI, physical trauma to the brain) can cause a variety of complications, health effects that are not TBI themselves but that result from it. The risk of complications increases with the severity of the trauma; [1] however even mild traumatic brain injury can result in disabilities that interfere with social interactions, employment, and everyday living.

During trauma surgery, when the blood flow is redirected to the brain and heart by an aortic clamp, blood goes away from other areas, and tissue in the lower extremities can die, causing gangrene, in which case surgeons must amputate the leg at higher and higher points, first at the shin, then at the knee, then at the thigh, to stay ahead of ...
