title: Jefferson fracture resulting in Collet-Sicard syndrome.
abstract: METHODS
  A case report and review of the literature.
  
  
  OBJECTIVE
  To increase awareness of and add to the spectrum of injury that can result from Jefferson fractures, to suggest a possible mechanism of injury, and to give a brief review of pertinent facts regarding C1 burst fractures and the Collet-Sicard Syndrome.
  
  
  BACKGROUND
  To the author's knowledge, this is the first reported case of a Jefferson fracture resulting in Collet-Sicard Syndrome. It represents only the second reported case of cranial nerve palsy caused by Jefferson fracture.
  
  
  METHODS
  A 56-year-old man sustained a C1 burst fracture in a rollover motor vehicle accident. Repeated neurologic examinations over the ensuing days revealed lesions of cranial nerves IX, X, XI, and XII on the left side.
  
  
  RESULTS
  Two weeks of traction, 10 weeks in a halo vest, and 2 weeks in a cervical collar resulted in adequate fracture healing and almost complete resolution of the patient's neurologic symptoms.
  
  
  CONCLUSIONS
  Although this is the first reported case of Collet-Sicard Syndrome caused by Jefferson fracture, the authors' review of the literature suggests that cranial nerve injuries may go unrecognized in some patients with C1 burst fractures. The importance of a thorough neurologic examination, including examination of the cranial nerves, in all cases of cervical spine injury cannot be overemphasized.
