title: Resection of a Hemivertebra Within the Craniocervical Junction.
abstract: METHODS
  Case report on resection of a hemivertebra at the craniocervical junction.
  
  
  OBJECTIVE
  To describe technique and result of a hemivertebra resection within the craniocervical junction (axis).
  
  
  BACKGROUND
  To our knowledge, this is the first report on a transoral and posterior hemivertebra resection at C2.
  
  
  METHODS
  A 42-year-old patient presented with coronal imbalance due to a hemivertebra at C2. Correction was performed by a combined anterior (transoral) and posterior approach with hemivertebra resection and compression instrumentation.
  
  
  RESULTS
  The postoperative course was uneventful. The radiographs showed a complete correction of the deformity with a perfect clinical result.
  
  
  CONCLUSIONS
  Hemivertebra resection at the craniocervical junction can be performed safely with good clinical and radiographical outcome.
  
  
  METHODS
  4.
