Hangman's fracture

Background

• Also known as traumatic spondylolisthesis
• Is an unstable spine injury
• Bilateral C2 pedicle fracture (leads to C2 displacing anteriorly on C3)

Clinical Features

Hangman's Fracture

• Seen in MVA, diving accidents, and judicial hangings (not in suicidal hangings)
  • Forced extension of an already extended neck
• Spinal cord damage is often minimal (diameter of neural canal is greatest at C2)
