RTI Surgical, Inc., based in Alachua, Florida, has announced the launch of a new platform of 3D printed, polymer based interbody fusion devices, Fortilink-TS and -L IBF Systems.
According to the company, “…The Fortilink-TS and -L Systems are intended for use in lumbar interbody fusion procedures at one or two adjoining levels in patients with degenerative disc disease.”
“TETRAfuse 3D Technology is the first 3D printed polymer-based interbody fusion device to incorporate a nano-roughened surface that has demonstrated, in a pre-clinical study, more notable trabecular bone ingrowth compared to PEEK and titanium-coated PEEK.”
“The Fortilink-L IBF System is intended for a lateral transpsoas approach to the lumbar spine, also known as lateral lumbar interbody fusion (LLIF) surgeries. The Fortilink-TS System is intended for traditional posterior approaches known as transforaminal lumbar interbody fusion (TLIF) or bilateral posterior lumbar interbody fusion (PLIF) surgeries. TETRAfuse 3D Technology features a nano-rough surface with antibacterial characteristics and is designed to participate in fusion without compromising mechanical integrity or radiographic visibility.”
John O’Toole, M.D., M.S., Professor of Neurosurgery at Rush University Medical Center in Chicago, Illinois, and one of the first surgeons to implant the Fortilink-TS device, added, “The introduction of TETRAfuse 3D Technology revolutionizes the interbody device market by combining a favorable modulus of elasticity, optimal imaging characteristics and a surface design promoting vigorous bone ingrowth. I believe TETRAfuse 3D Technology meets all the criteria for an interbody through enhanced biology, biomechanics and ease of use to help improve outcomes for patients.”
Joseph O’Brien, M.D., M.P.H., founder of the Washington Spine & Scoliosis Institute at Ortho Bethesda in Bethesda, Maryland, and one of the first surgeons to implant the Fortilink-L device, told OTW, “In my experience, PEEK material is hydrophobic whereas TETRAfuse 3D Technology has a nano scale rough surface architecture and is hydrophilic. This creates a more favorable environment for new bone growth, while maintaining the radiolucency of PEEK to monitor fusion status.”
“I know many surgeons, like me, looking for interbody implant solutions that can be used with different types of bone graft substitute without compromising outcomes. With superior implant technology, like TETRAfuse 3D Technology, I can select a more cost-effective bone graft substitute and still expect as good or better results more quickly.”
