Hangman's fracture vs hanged-man's fracture vs hangee's fracture.

摘要

Traumatic spondylolisthesis of the axis, which consists of bilateral fractures of the C-2 pedicles and subluxation of C-2 on C-3, has been termed the "hangman's fracture". The earliest evidence of a formal execution by hanging is found in Homer's Odyssey, written between 800 and 600 BCE [3], and the submentally placed knots, which are known as the hangman's knots, were used in judicial hangings in Britain from the nineteenth century [1]. Creating a fracture-dislocation of C-2 on C-3, it delivers a certain, instant and painless death. A hangman's fracture is the very condition that hangmen should strive to achieve [2].
