TrellOss®-A Porous Ti Interbody System

A new foundation for growth.

System Features

A 3D printed titanium interbody platform featuring a scaffold structure with 70% porosity and a 7 micron roughened surface topography to foster a cellular relevant environment for adhesion and bone ingrowth.1


  • Aligned pore structure allows optimal fluoroscopy when assessing fusion post-operatively.
  • Open architecture with 70% porosity including varying pore sizes of 300, 500, and 700 microns that mimic cancellous bone allowing for a conducive environment for cellular activity.1,5,6,7


  • Lock sleeve insertion prevents loosening upon impaction.
  • Scaffolding structure provides additional surface area 2,3 and an elastic modulus similar to PEEK.8


  • Anti-migration teeth flank the lateral walls.
  • 7 micron surface texturing enhances the wicking nature9 and creates an environment for potential cellular adhesion.2,3,4

Sterile Packed

Implants are sterile packed to reduce risk of contamination and hospital reprocessing costs.


  • 2 lumens for graft packing and containment.
  • Distractor inserter option.


  • Footprint

    24 x 32, 27 x 36.

  • Height*

    8 mm–18 mm, 10 mm–20 mm, 12 mm–20 mm.

    *2 mm increments.

  • Lordosis

    8˚, 14˚, 20˚.
