Introducing TrellOss-A SA Porous Ti Interbody System

A 3D printed porous titanium interbody device with aligned 300, 500, and 700 μm pores and a 7 μm roughened surface; TrellOss-A SA is designed to provide appropriate endplate coverage with three footprint offerings, and allow for consistent bone purchase with optimized location of screw pockets. Implants are sterile-packed to reduce the risk of contamination and hospital reprocessing costs.

TrellOss-A SA Highlights

  • Rigid teeth help to resist implant migration
  • Central window for graft packing and containment
  • Optimized location of screw pockets to allow for consistent bone purchase

A New Foundation for Growth
