title: Chiropractic correction of atlantoaxial rotatory fixation.
abstract: OBJECTIVE
  To discuss the diagnosis, management and possible mechanism of atlantoaxial rotatory fixation.
  
  
  METHODS
  An 11-yr-old girl with significant head tilt of 7 months' duration sought chiropractic evaluation. Her history included indirect head and neck trauma from a motor vehicle accident and prior manipulative and therapeutic treatment. There was minimal muscular hypertonicity, except for the sternocleidomastoid muscle on the side opposite head tilt. The head seemed to be locked in a classic "cock robin" position. Radiological examination revealed asymmetry of the atlanto-odontoid interval, suggesting occipital-atlantoaxial joint dysfunction. A diagnosis of atlantoaxial rotatory fixation was made.
  
  
  RESULTS
  Treatment included vectored/linear, upper cervical, high-velocity, low-amplitude chiropractic manipulation of the atlas vertebra, mobilizing manipulation and stretching exercises. Complete resolution occurred.
  
  
  CONCLUSIONS
  This single case study suggests that chiropractic manipulation may be a viable treatment option for atlantoaxial rotatory fixation. Further investigation into manipulation as a treatment should be pursued.
