title: Horner's syndrome after posterior spinal fusion in a child: a case report.
abstract: METHODS
  A case report of a complication after posterior spinal fusion.
  
  
  OBJECTIVE
  To present the clinical findings of a Horner's syndrome after posterior spinal fusion.
  
  
  BACKGROUND
  A 14-year-old girl underwent posterior spinal fusion for idiopathic scoliosis.
  
  
  METHODS
  Clinical examination and pharmacologic pupillary testing were used to diagnose Horner's syndrome.
  
  
  RESULTS
  After surgery, the patient developed a left-sided Horner's syndrome. The Horner's syndrome had resolved 6 months after surgery except for slight ptosis.
  
  
  CONCLUSIONS
  This is the first reported case of Horner's syndrome occurring after posterior spinal fusion without the use of epidural analgesia.
