title: Treatment of cervical cord compression, caused by hereditary multiple exostosis, with laminoplasty: a case report.
abstract: METHODS
  Case report.
  
  
  OBJECTIVE
  Successful excision of the exostosis within the spinal canal.
  
  
  BACKGROUND
  Myelopathy caused by exostosis within the spinal canal developed in a 13-year-old boy with hereditary multiple exostosis.
  
  
  METHODS
  Spinous process-splitting laminoplasty with an ultrasonic knife was performed to remove the mass and minimize the possibility of postlaminectomy kyphosis.
  
  
  RESULTS
  The spinal canal exostosis with cervical cord compression was excised successfully with laminoplasty. After surgery there has been no recurrence of tumor, and the stability of the cervical spine has been preserved.
  
  
  CONCLUSIONS
  This is the first report of laminoplasty as a useful surgical approach for intraspinal exostosis to prevent postoperative cervical instability.
