Stryker Gains Clearance for 3D-printed Lumbar Cage

FDA has cleared a Stryker’s Spine division 510(k) for its Tritanium TL Curved Posterior Lumbar Cage, a 3D-printed interbody fusion device intended for use as an aid in lumbar fixation. The hollow implant has a “unique configuration of both solid and porous structures, which are simultaneously built using AMagine,” according to the company. AMagine is Stryker’s proprietary approach to implant creation using 3D printing. The technology is designed for fusion and inspired by the microstructure of cancellous bone, it adds.

The device features open central graft windows and lateral windows to help reduce cage stiffness, aid in visualization of fusion, and allow for bone graft containment, Stryker’s Spine says. It is also shaped for steerability with multidirectional teeth that the company says allow for multidirectional fixation as the cage can be steered and rotated to the surgeon’s desired placement.
