Contrecoup Injury Animation – Part 2 – Hyperextension Hyperflexion Injury
This animation, second in a set of four, depicts the mechanism of a hyperextension hyperflexion contrecoup injury. A sudden impact from behind causes the head to accelerate backwards while the brain moves forward, striking the front of the skull. Hyperextension of the cervical spine causes a fracture of the left lateral mass of C3. The head then recoils forward, causing the brain to move backwards, striking the back of the skull.
