FDA Clears Stryker 3D Printed Cervical Cage

FDA has cleared a Stryker Spine division 510(k) for its Tritanium C Anterior Cervical Cage, a 3D-printed interbody fusion cage intended for use in the cervical spine. The device is constructed from Stryker’s proprietary Tritanium In-Growth Technology, a highly porous titanium material designed for bone in-growth and biological fixation, according to the company. “The unique porous structure of the Tritanium material is designed to create a favorable environment for cell attachment and proliferation, as demonstrated in an in-vitro study,” it says.

The cervical cage features an open central graft window and lateral windows to “help reduce stiffness of the cage and minimize subsidence,” Stryker says. In addition, the large graft window allows for bone graft containment. “Engineered for stability, the cage has serrations on the superior and inferior surfaces designed for bidirectional fixation and to maximize surface area for endplate contact with the cage,” the company adds.
