Loss of Mass and Surface Topography in 3-Dimensional-Printed Solid Titanium Cages Upon Impaction: An In Vitro Model
Three-dimensional-printed titanium interbody fusion cages underwent loss of mass and alteration in surface topography during benchtop testing replicating physiologic conditions. There was an endplate- and region-specific postimpaction change in roughness parameters. The anterior surface experienced the largest change in surface parameters postimpaction. Our results have implications for future cage design and pre-approval testing of 3D-printed implants.
