title: Cervical nerve injection: computed tomography guidance with intravenous contrast and extraforaminal needle placement. Series of seven consecutive case reports.
abstract: BACKGROUND
  Image-guided cervical nerve injections are being performed with increasing frequency. Severe complications are being reported.
  
  
  OBJECTIVE
  The purpose of this study is to introduce a technique for cervical nerve injection that may decrease the possibility for severe complications.
  
  
  METHODS
  This is a series of case reports describing the technique and clinical follow-up.
  
  
  METHODS
  The sample comprises seven consecutive cases of unilateral neck and arm pain referred for cervical nerve injection.
  
  
  METHODS
  Retrospective evaluation of pain relief before and after the injection and at follow-up is reported as case studies.
  
  
  METHODS
  The technique for computed tomography guided cervical nerve injection is described with case reports of seven consecutive patients.
  
  
  RESULTS
  The results are case reports of each of the seven patients after unilateral cervical nerve injection.
  
  
  CONCLUSIONS
  A technique for cervical nerve injection is described with the results of the injection. This technique may allow some standardization in the procedure, decrease the learning curve for training physicians, and minimize the potential complications.
