Stryker’s Spine Division to Debut 3D Printed Tritanium Posterior Lumbar Cage Spinal Implant

3dp_spinecage_stryker_logoThis 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 can debut their newest Tritanium technology. Stryker’s proprietary Tritanium technology has now been applied to spinal implants turn it intod to encourage healthy regrowth of the bone tissue, and to reduce any strain or injure caused by being implanted. The Tritanium Posterior Lumbar (PL) Cage is a 3D printed intervertebral body fusion device which was turn it intod to assist 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. Whilst the condition may be referred to as a disease, it is in fact only a degenerative condition of one or additional of the discs in the spine, typically related to effortless aging. And despite being classified as degenerative, the condition won’t progress with age – in fact the symptoms in fact tend to lessen with age. In this case degenerative is only a description of the condition of the disc, not a prognosis. That being said, severe or persistent cases of DDD which cannot be solved with medication or physical therapy may require to be corrected surgically.

There are in fact several surgical options on the market to those suffering of DDD, and one of the additional not long ago turn it intod is the new Tritanium Posterior Lumbar Cage of Stryker. This implant is turn it intod via Stryker Spine Division’s Tritanium technology, which is a proprietary system of 3D printing via a specially turn it intod material. Tritanium is a incredibly porous titanium alloy material which can encourage bone in-growth and biological fixation. This is due to the material’s porous internal structures which mimic cancellous bone, or the spongy trabecular bone material discovered within of human bones.

“We are elated to bring this technology innovation to spine surgeons and their patients. Stryker is a pioneer in 3D additive making, investing only of 15 years in research and development. Unlike traditional making techniques, the flexibility of our 3D additive making capabilities allows for us to exactly engineer and turn it into porous Tritanium devices. The Tritanium PL Cage is an amazing addition to our expanding suite of one-of-a-kind spinal products,” Stryker Spine Division President Brad Paddock explained.

The Tritanium Posterior Lumbar Cage is implanted in what is called a posterior approach, which can not injure any muscle tissue around the spine. The cage can be on the market in several various sizes, widths, lengths, heights, and lordotic angles which can manufacture it effortless to adapt to a wide variety of various patients’ anatomies. In addition, the geometry contains sizeable lateral windows and open architecture which can allow doctors to easily visualize bone fusion and regrowth on CT scans and X-rays, so recovery can be easily monitored. The turn it into in addition maximizes the surface area for endplate (the top and bottom parts of the vertebrae) contact with the spinal cage implant, and can decrease any injure to them.

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


The Stryker 3D Printed Tritanium Posterior Lumbar Cage Spinal Implant

Stryker’s Tritanium Posterior Lumbar Cage is the only latest medical implant to take advantage of high end medical-grade 3D printing to turn it into porous geometries which encourage full integration with the human body. The purpose of via porous structures is to take on to simulate the mechanical properties of bone, while yet offering the durablity and durability of a medical implant. The implant has succeded in FDA approval and has been cleared for use in the lumbosacral spine. It is expected to be turn it intod on the market to surgeons mid-2016.

Stryker already develops several Tritanium devices, mostly for knee and joint replacement, yet they have in addition turn it intod skull plates and other less common implants. Stryker offers their medical products to additional than one hundred countries, in areas as diverse as Orthopaedics, Medical and Surgical, and Neurotechnology and the Spine.
