Stryker’s Tritanium PL Cage is a hollow, rectangular implant that consists of a unique configuration of both solid and porous structures, which are simultaneously built using 3D Additive Manufacturing applying Stryker’s proprietary Tritanium In-Growth Technology.
Developed tominimize subsidence
The Tritanium PL Cage demonstrated better resistance to subsidence than other commercially available posterior lumbar interbody cages constructed out of different materials, including those with a larger footprint.
- Porous Tritanium has an elastic modulus that falls between cancellous and cortical bone
- Large central graft and lateral windows help to reducethe overall stiffness of the cage and allow room for bone graft to be packed inside the cage
- Teeth are designed to increase the surface area of the device in contact with bone in order to help normalize load transmission and minimize subsidence
Created to allowimaging
With large lateral windows, Tritanium PL allows visualization on CT and X-ray.
Engineered for stability
The precisely angled teeth of the Tritanium PL Cage are designed to allow bidirectional stability, with an expulsion force that was shown to be 22% greater than the insertion force.
- Teeth with a smooth leading edge aid movement across the vertebral endplates
- High coefficient of friction for initial stability
About Stryker Spine
Stryker’s Spine division also introduced its Tritanium® first product 3D-printed interbody fusion cage intended for use in the cervical spine, at the North American Spine Society (NASS) Annual Meeting, Oct. 25-28, 2017.Tritanium Cages are built using Stryker’s proprietary Tritanium In-Growth Technology, a novel, highly porous titanium material designed for bone in-growth and biological fixation.AMagine™ technology, Stryker’s proprietary approach to implant creation using additive manufacturing, allows for the production of randomized yet reproducible porous structures.
