Stryker's spine division revealed results from a pre-clinical study for its 3D-printed Tritanium PL Interbody Cages.
Here are five takeaways:
1. The study analyzed the biomechanical, radiographic and histological performance of implants featuring various surface technologies in an ovine lumbar interbody fusion model.
2. Researchers compared traditional PEEK cages, plasma-sprayed titanium-coated PEEK cages and Stryker's Tritanium PL cages.
3. The study found the Tritanium PL cages demonstrated reductions in segmental motion. Additionally, the cages exhibited increases in construct stiffness on all three loading directions between the eight- and 16-week post-implant time points.
4. At eight weeks and 16 weeks, micro–CT and histological data found Tritanium PL cages demonstrated greater total bone volume.
5. Stryker presented the findings at the North American Spine Society annual meeting in Boston from Oct. 26 to Oct. 29.
