title: Chordoma in the cervical spine managed with en bloc excision.
abstract: METHODS
  En bloc resection of a chordoma in the midcervical vertebral spine was performed.
  
  
  OBJECTIVE
  To document the surgical technique used for en bloc excision of a chordoma arising in the midcervical spine.
  
  
  BACKGROUND
  Malignant tumors arising in long bones are excised en bloc. The authors recently designed a technique for en bloc resection of malignant tumors in the thoracolumbar spine using the T-saw. However, this technique is difficult in tumors of the cervical spine, and there are no previous reports of successful en bloc resection of such tumors.
  
  
  METHODS
  Using an anterior approach, the ipsilateral vertebral artery was ligated. This was followed by sharply cutting the pedicle of the cervical vertebra with a specially designed T-saw.
  
  
  RESULTS
  En bloc excision of chordomas in the cervical spine was achieved using the T-saw.
  
  
  CONCLUSIONS
  Although the surgical margin was intralesional in a small area, the technique used in this case study indicates that en bloc excision of such tumors can be used with a safety margin even in the cervical spine.
