Rail 4D


Rail 4D Technology incorporates a “beam–like” design to aid in the restoration of sagittal balance, while maintaining a low profile.



  • Uniquely shaped to minimize implant volume of pedicle screws

  • Intraoperative variability of rod rigidity with one pedicle screw system

  • Lower profile than set screw based systems

  • Due to the beam-like design, reducing the Mesa Rail crickets will inherently result in rotation of the vertebral bodies as they are pulled up to the Mesa Rail
