Stryker introduces new cage sizes of 3D-printed spinal implants

Stryker’s Spine Division has announced the launch of a variety of new cage sizes for its 3D-printed Tritanium Posterior Lumbar Cage.

According to a company press release, the Tritanium Posterior Lumbar (PL) Cage was initially launched with four footprint options, eight height options and two lordosis options. There are now several additional sizes, including a hyper-lordotic (12º) cage option, as well as two new footprints: 9 mm x 32 mm and 11 mm x 32 mm.

The technology allows for the creation of porous structures to mirror cancellous bone in pore size, porosity level and interconnectivity of pores. The cage features fully interconnected pores that span the endplate. Its large lateral windows and open architecture reportedly allow for visualization of fusion on CT and X-ray. In addition, its solid-tipped, angled serrations allow for bi-directional fixation and to maximize surface are.

“Stryker is a pioneer in 3-D additive manufacturing, investing nearly 15 years in research and development,” Bradley Paddock, president of Stryker Spine Division, said in the release. “Unlike traditional manufacturing techniques, the flexibility of our 3-D additive manufacturing capabilities allows us to precisely engineer and produce porous tritanium devices. We are excited to continue growing our unique suite of tritanium spinal products.”
