TrellOss™-TS Porous

Porous Ti Interbody System

TrellOss-TS is 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

  • Rigid teeth help to resist implant migration
  • Bullet-tip nose to aid in implant insertion
  • Central window for graft packing and containment
  • Implants are sterile-packed to reduce the risk of contamination and hospital reprocessing costs
  • Inline and offset MIS insertion options

A New Foundation for Growth

Porosity

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 activity1,5,6,7

Texture

7 micron surface texturing creates an environment for potential cellular adhesion2,3,4

Structure

Scaffolding structure provides additional surface area2,3
