CentraFix® Midline Fixation System

The CentraFix Midline Fixation System is a posterior thoracolumbar pedicle screw system designed for a midline approach with a medial to lateral cortical bone trajectory. The system contains modular tulip heads and screw shanks designed specifically for cortical fixation. CentraFix allows for unmatched intraoperative visualization and surgical flexibility.

  • Modular tulip heads allow for increased visibility and simplified distraction
  • Self-drilling, self-tapping cortical screw threading provides easy screw starting in the intended trajectory
