Stryker Launches Next Generation Trident® II Acetabular System
Published: Mar 06, 2018
MAHWAH, N.J., March 6, 2018 /PRNewswire/ -- Stryker's Joint Replacement Division today announced the commercial launch of its Trident® II Acetabular System, featuring Trident II Tritanium, at the 2018 Academy Meeting. Trident II Tritanium combines the reproducibility of Stryker's proprietary AMagine™ additive manufactured Tritanium® In-Growth Technology and SOMA-verification process with the precision of Mako Robotic-Arm Assisted Surgery which enables surgeons to have a more predictable surgical experience.
Building on Stryker's Trident brand legacy and successful clinical performance2-6, the design of Trident II Tritanium features a slim wall, enabled by additive manufacturing, that allows for large femoral head size options7 and optimal poly thickness to potentially aid in greater range of motion8, joint stability8, and lower risk of dislocation9. Its Tritanium surface is designed to mimic the complex, highly porous characteristics of cancellous bone10 to help promote long-term biologic fixation.
Additionally, Trident II shells maintain Stryker's Innerchange™ Locking Mechanism, giving surgeons intraoperative flexibility to choose from clinically proven11-13 bearing options including: Modular Dual Mobility (MDM), X3 precisely engineered polyethylene or Trident constrained liners.
"I have trusted the clinical performance of Trident for many years, and I'm thrilled with the latest evolution of Stryker's portfolio of acetabular implants," said Walter B. Beaver, Jr., MD, a board-certified orthopaedic surgeon at OrthoCarolina. "With Trident II Tritanium, Stryker uses cutting-edge 3D-printing technology to uniquely address biological fixation and hip stability, which ultimately enhances my surgical experience."14
"We're excited to see implant design and innovative technology converge to bring important new products to market which will ultimately help make healthcare better," said Stuart Simpson, President of Stryker's Joint Replacement Division. "This System highlights our Trident II Tritanium shell, bringing together our leading additive manufacturing expertise, SOMA-design process and Mako Robotic-Arm Assisted Surgery System."
Stryker's AMagine™ Institute, its additive manufacturing innovation center in Cork, Ireland, is the largest orthopaedic implant additive manufacturing facility in the world. The company began investigating additive manufacturing technology in 2001 with academic research institutions and has since developed a state-of-the-art production process: AMagine. This latest advancement in joint replacement technology expands Stryker's additive manufacturing implant footprint across multiple orthopaedic applications, including hip, knee and spine.
The Trident II Tritanium Acetabular System received initial 510(k) market clearance from the U.S. Food and Drug Administration in October 2016 and Trident II Tritanium Clusterhole was available through a limited market release in 2017. The full Trident II Acetabular System launching in 2018 offers five shell options: three in Tritanium (Clusterhole, Multihole or Solidback) and two Hydroxyapatite (Hemi Clusterhole or PSL Clusterhole) surfaces.
More than 2.5 million people are living with a hip replacement in the United States, and demand is expected to further increase due to an aging baby boomer population, higher rates of arthritis treatment and increasing demands for improved mobility15.
Stryker will showcase its latest technologies, including the Trident II Acetabular System, at the Academy meeting in New Orleans (booth #2451) from March 6-10, 2018.
