title: Transarticular screw fixation using neuronavigation: Technique.
abstract: BACKGROUND
  Transarticular screw placement needs highly accurate imaging. We assess the efficacy and accuracy of C1-C2 transarticular screw fixation using neuronavigation and also cast a technical note on the procedure.
  
  
  METHODS
  This study included a total of nine patients who underwent transarticular screw fixation using the neuronavigation system. A total of 15 screws were placed. All patients underwent postoperative CT scan with 3-Dimensional (3-D) reconstruction to check for the accuracy of implantation.
  
  
  RESULTS
  One patient had encroachment of the transverse foramen but there was no vertebral artery injury. There were no clinical complications or adverse sequelae.
  
  
  CONCLUSIONS
  Neuronavigation is extremely helpful in C1-C2 transarticular screw fixation and gives excellent accuracy.
