Coup & Contrecoup Injuries
With a head injury, a coup injury to the brain occurs under the site of impact with an object, and a contrecoup injury occurs when the side opposite the coup injury is impacted. Coup and contrecoup injuries usually involve brain contusions and are types of traumatic brain injury (TBI) in which the brain is bruised in some form of impact to the skull with a fixed or moving object, very frequently a car or trucking accident. When a moving object such as the materials of a car impacts the stationary skull, coup injuries are normally seen, and contrecoup injuries are typically seen when a moving head strikes a stationary object. In a coup injury, the head stops abruptly and the brain strikes the inside of the skull.
A coup injury can also be caused during an impact when the skull is forced inward and impacts the brain. Then the skull is forced inward, this in turn sets the drain in motion toward the opposite side of the skull which results in a contrecoup injury. The injuries can also be caused by mere acceleration or deceleration. In other words, there does not have to be an impact for such injuries to be caused. In TBIs associated with acceleration or deceleration without impact, the brain still can bounce off one side of the skull and go on to strike the opposite side of the skull.
