Rail 4D™ Technology

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

  • Uniquely Shaped to Provide Enhanced Rigidity*, While Minimizing 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
