A school boy aged seventeen was involved in Hangman's fracture, in which he has the hyperextension of the upper cervical spine from diving. He has the severe neck pain and the temporary quadriplegia immediately after in ury.
Radiological sign showed the fracture of C2 arch resulting from extension and compression of the upper cervical spine following a blow to the head, producing a Hangman's fracture, as suggested by Cornish (1968). Skull traction using Glisson's sling was applied with collar ten weeks after injury and anterior spinal fusion from C2 to C3 was performed eleven weeks after injury.
