title: Chiropractic adjustment to the cervical spine and the Arnold-Chiari malformation.
abstract: OBJECTIVE
  To present two cases in which patients with Type I Arnold-Chiari malformation (ACM) were treated with adjustments to the cervical spine for conditions unrelated to the anomaly.
  
  
  METHODS
  The ACM is an anomaly of central nervous system development in which structures from the posterior fossa descend below the level of the foramen magnum.
  
  
  RESULTS
  The patients reported were adjusted multiple times to the cervical spine. No ill effects or complications were noted related to the ACM.
  
  
  CONCLUSIONS
  Asymptomatic Type I ACM is not necessarily a contraindication to skilled adjustments to the cervical spine.
