Curved Posterior Lumbar Cage Stryker
Tritanium TL Curved Posterior Lumbar Cage.
Stryker, a leading medtech company, has seen its 3D printed Tritanium TL Curved Posterior Lumbar Cage receive 510(k) clearance from the U.S. Food and Drug Administration (FDA).
The interbody fusion cage is intended for use as an aid in lumbar fixation, a procedure which sees multiple vertebrae anchroed to each other through a synthetic device to reduce vertebral mobility and avoid injuries. It consists of a configuration of both solid and porous structures, which are built with the company’s AMagine implant additive manufacturing approach and Tritanium Technology.
Tritanium was developed for bone in-growth and biological fixation. Its porous structure is designed to create a favourable environment for cell attachment and proliferation, and is better able to retain fluid than traditional titanium, per Stryker. It has been utilised to bring to market this Curved Posterior Lumbar Cage, available to surgeons from Q2 of 2018, which Stryker believes will have a big impact in spinal surgery.
“The Tritanium TL Cage is the latest addition to our highly successful Tritanium portfolio, which has been embraced by spinal surgeons nationwide,” commented Bradley Paddock, President of Stryker’s Spine division. “The TL cage is accompanied by a new Anterior Placement System that is designed for versatility and procedural flexibility. From instrumentation ergonomics and visualisation, to a simplified technique with tactile feedback, Tritanium TL’s Anterior Placement System and cage design redefine implant steerability for surgeons.”
Featuring open central graft windows and lateral windows, the Tritanium TL Curved Posteiror Lumbar Cage has reduced stiffness of the cage, greater visualisation of fusion, and better containment of bone graft. The multidirectional teeth ensures fixation can occur in several directions as the cage can be steered and rotated to the surgeon’s desired placement. They are also designed to maximise surface area for endplate contact with the implant. Moreover, the cage has a smooth, tapered leading edge to facilitate insertion into the intervertebral space and a central column spanning endplate to endplate for structural integrity. Stryker has also considered the varying possibilities with regards to patient anatomy, and thus the Tritanium TL Cage will be available in a broad range of footprints, heights, and lordotic angles.
