Study To Be Presented at NASS 2016 Evaluating Bone In-Growth for Stryker’s 3D-Printed Tritanium® PL Cage

Stryker’s Spine division today announced that the results of a
pre-clinical study for its new 3D-printed Tritanium
PL Interbody Cage will be presented at the North American Spine
Society (NASS) Meeting. The conference is being held in Boston, Oct.
26-29, 2016, and Stryker’s Spine division will demonstrate the Tritanium
PL Cage at booth No. 1415.
The objective of this study was to compare the biomechanical,
radiographic, and histological performance of implants with different
surface technologies in an ovine lumbar interbody fusion model. The
interbody fusion cages involved in this study included traditional PEEK
cages, plasma-sprayed titanium-coated PEEK cages, and Stryker’s
3D-printed, highly porous Tritanium PL cages.
The results from this study demonstrated that the Tritanium PL cages
exhibited reductions in segmental motion and increases in construct
stiffness across all three loading directions between the 8- and 16-week
post-implant time points, which was not seen within the PEEK and
plasma-sprayed titanium-coated PEEK cage groups (p<0.02).
Furthermore, micro–CT and histological data demonstrated greater total
bone volume within the Tritanium PL Cage at both 8 and 16 weeks compared
to all other treatment groups (p<0.01).
According to Bradley Paddock, president of Stryker’s Spine division,
additive manufacturing, also known as 3D printing, allows for the
creation of a material with porous structures that resemble cancellous
bone, a type of spongy bone tissue.
“Stryker’s proprietary Tritanium Technology, a novel, highly porous
titanium alloy material designed for bone in-growth and biological
fixation, is based on new additive manufacturing techniques pioneered by
Stryker over nearly 15 years,” Paddock said. “Tritanium, and this
important new study, demonstrate Stryker’s commitment to bringing the
latest technologies to our customers, and a growing number of surgeons
are turning to our new Tritanium PL Cage.”
