Stryker presents 3D printed tritanium posterior lumbar cage spinal implant

This week at the American Association of Neurological Surgeons (AANS) Annual Scientific Meeting, which is being held in Chicago until May 4, medical technology company Stryker will debut their newest Tritanium innovation. Stryker’s proprietary Tritanium technology has now been applied to spinal implants designed to encourage healthy regrowth of the bone tissue, and to reduce any strain or damage caused by being implanted. The Tritanium Posterior Lumbar (PL) Cage is a 3D printed intervertebral body fusion device that was developed to help patients dealing with lumbar spinal fixation due to ongoing back problems brought on by degenerative disc disease.

Despite its name, degenerative disc disease (DDD) is neither a disease nor is it degenerative in the classic sense. While the condition may be referred to as a disease, it is actually simply a degenerative condition of one or more of the discs in the spine, typically related to simple aging. And despite being classified as degenerative, the condition won’t progress with age – in fact the symptoms actually tend to lessen with age. In this case degenerative is simply a description of the condition of the disc, not a prognosis. That being said, severe or persistent cases of DDD that cannot be solved with medication or physical therapy may need to be corrected surgically.

There are actually several surgical options available to those suffering from DDD, and one of the more recently developed is the new Tritanium Posterior Lumbar Cage from Stryker. This implant is made using Stryker Spine Division’s Tritanium technology, which is a proprietary process of 3D printing using a specially developed material. Tritanium is a extremely porous titanium alloy material that will encourage bone in-growth and biological fixation. This is due to the material’s porous internal structures that mimic cancellous bone, or the spongy trabecular bone material found inside of human bones.

“We are pleased to bring this technology advancement to spine surgeons and their patients. Stryker is a pioneer in 3D additive manufacturing, investing nearly 15 years in research and development. Unlike traditional manufacturing techniques, the flexibility of our 3D additive manufacturing capabilities allows us to precisely engineer and produce porous Tritanium devices. The Tritanium PL Cage is an exciting addition to our growing suite of unique spinal products,” Stryker Spine Division President Brad Paddock explained.

The Tritanium Posterior Lumbar Cage is implanted in what is called a posterior approach, which will not damage any muscle tissue around the spine. The cage will be available in several different sizes, widths, lengths, heights, and lordotic angles that will make it easy to adapt to a wide variety of different patients’ anatomies. Also, the geometry contains large lateral windows and open architecture that will allow doctors to easily visualize bone fusion and regrowth on CT scans and X-rays, so recovery can be easily monitored. The design also maximizes the surface area for endplate (the top and bottom parts of the vertebrae) contact with the spinal cage implant, and will minimize any damage to them.

“Spine surgeons need a cage that has the capability of bony integration or bony in-growth, as well as radiolucency so that we can evaluate the fusion long term. Because Tritanium has favorable radiographic capabilities, as well as the integrative surface technology, that really in my opinion is what I would ask for from an interbody cage,” said Dr. Wellington Hsu, M.D., Orthopaedic Surgeon at Northwestern Medical Group.
