Stryker touts Tritanium PL cage data
Stryker‘s (NYSE:SYK) spine division touted results from a preclinical study of its 3D-printed Tritanium PL Interbody Cage compared to traditional PEEK cages and plasma-sprayed, titanium-coated PEEK cages.
The study showed that Stryker’s cages demonstrated reductions in segmental motion and increases in construct stiffness between the 8 and 16-week post-implant time points. Micro-CT and histological data showed greater total bone volume within the Kalamazoo, Michigan-based company’s cage compared to all other treatment groups.
Additive manufacturing, or 3D-printing, created a material with porous structures that mimic a type of spongy bone tissue called cancellous bone, according to Bradley Paddock, the president of Stryker’s spine division.
