Posterior Pedicle Screw Fixation

摘要: Pedicle screw fixation has already been proved to provide the strongest stability for reconstruction of unstable cervical spine in several biomechanical studies. However, it generally considered too risky at C3–6 levels due its potential injury surrounding neurovascular structures such as vertebral arteries, spinal cord, or nerve roots. Anatomically, pedicle diameter is smaller than that thoracolumbar pedicles, and axis largely inclined transverse plane. Therefore, accurate identification entry point matched with trajectory angle required successful placement screws. This chapter introduces treatment injuries describes indications, procedural steps, imaging technique, technical pitfalls, postoperative course detail.
