Atlas Lateral Mass Long-Tail Reduction Screw: Axis Pedicle Screw and Rod Fixation Technique

  • Jun Yang
Part of the Translational Medicine Research book series (TRAMERE)


This chapter describes the reduction technique for atlantoaxial dislocation using C1 long-tail reduction lateral mass screw and C2 pedicle screw. Firstly, the spondylolisthesis long-tail reduction screws at the atlas and pedicle screws of the axis are placed, and the rods to the screws of the axis are locked. Then, the nuts of C1 long-tail reduction lateral mass screw are gradually fastened. As a result, the screw-rod lever system distracts the atlas backward and pushes the axis downward and forward, thus achieving reduction of the atlantoaxial joint dislocation.
