TrellOss®-L MPF Porous Ti Interbody System

A new foundation for growth.

A New Foundation for Growth

The TrellOss-L implant is designed with rigid teeth to help resist implant migration. The implant’s bullet-tip nose aids in implant insertion and is compatible with all MPF plates.

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


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


  • Bullet-tip nose to aid in implant insertion.
  • Scaffolding structure provides additional surface area 2,3 and an elastic modulus similar to PEEK8.
  • Central windows for graft packing and containment.


  • Rigid teeth help to resist implant migration.
  • 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.
