TrellOss™-TS Porous

Porous Ti Interbody System

TrellOss-TS is a 3D printed titanium interbody system 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

Product Features

  • 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
  • Depth options of 22 , 26 and 30 mm
  • Parallel and 6° lordotic options
  • Heights of 7-16 mm (parallel) and 8-16 mm (lordotic) in 1 mm increments

Technology
