title: Hangman's fracture in an osteogenesis imperfecta patient.
abstract: BACKGROUND
  Traumatic spondylolisthesis of the axis, also known as a hangman's fracture, is a well-described entity but is relatively uncommon. There are only two published reports of these fractures occurring in pediatric patients with osteogenesis imperfecta, a disorder that predisposes patients to long bone fractures.
  
  
  METHODS
  We present a unique case of an adult woman with osteogenesis imperfecta who sustained an Effendi type II hangman's fracture.
  
  
  CONCLUSIONS
  Effendi type II fractures can be conservatively managed via rigid or nonrigid cervical orthosis.
