title: C1-C2 pedicle screw fixation with rigid cantilever beam construct: case report and technical note.
abstract: OBJECTIVE
  Transarticular screw fixation of the C1-C2 complex provides immediate rigid fixation of the unstable spine. The technique is not feasible in a certain proportion of patients because of the position of the vertebral artery or the patient's body habitus.
  
  
  METHODS
  The authors describe a rigid screw technique for the surgical treatment of a woman who was excluded as a candidate for C1-C2 transarticular screw fixation.
  
  
  METHODS
  C1-C2 pedicle screw fixation was achieved using a fixed moment arm cantilever beam system. This system provided immediate rigid fixation of the C1-C2 complex in a patient who was not a candidate for transarticular screw fixation.
  
  
  CONCLUSIONS
  This technique is technically more forgiving than posterior transarticular screw fixation and may be applied to a broader spectrum of patients.
