CONDUIT™ Interbody Platform | EIT™ Cellular Titanium 3D printed cellular titanium implants that feature 80% porous macro-, micro- and nanostructures, are designed to mimic cortical and cancellous bone, and facilitate fusion.1,2 BONE-MIMICKING CELLULAR TITANIUM MATERIAL – Cellular structure of the material is designed to mimic the published properties of bone and facilitate fusion EXCELLENT VISUALIZATION – Ability to clearly visualize the cage intra- and post-operatively on imaging modalities without interference3,4 TARGETED MODULUS OF ELASTICITY – Modulus of Elasticity similar to cancellous bone (Figure 1) Macrostructure Surface roughness has been shown to have a beneficial effect on cell differentiation and proliferation in in-vitro studies of osteoblast-like cells cultured on similar roughened titanium materials MICROSTRUCTURE In-vitro studies have reported greater osteoblastic differentiation in human stem cells cultured on similar porous titanium constructs compared to solid titanium surfaces9 In-vivo studies with similar porous titanium materials show that bony in-growth is increased at the 500-700 μm pore size range compared to larger or smaller pores10-12 The porosity of cancellous human bone is typically 50-90%13 Based on this published science, CONDUIT™ Implants are designed with 80% porosity and 700 μm pore size NANOSTRUCTURE Similar titanium materials with nanoscale features have shown in in-vitro studies to lead to increased osteoblast adhesion when compared to conventional titanium materials15 All CONDUIT Implants undergo acid etching and heat treatment to promote micro-and nanoscale surface roughness
