The commercial launch of Fortilink-TS and –L IBF systems (RTI Surgical) with TETRAfuse 3D technology has added to a growing series of interbody fusion devices featuring RTI Surgical’s proprietary TETRAfuse 3D technology.
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-rough surface that has demonstrated, in a pre-clinical study, more notable trabecular bone ingrowth compared to PEEK and titanium-coated PEEK.
“The Fortilink-L system is the first osteointegrative, radiolucent cage,” says Joseph O’Brien (Washington Spine & Scoliosis Institute, OrthoBethesda, Bethesda, USA), one of the first surgeons to implant the Fortilink-L device. “While other companies are focusing on titanium, TETRAfuse 3D technology offers ingrowth features that help the implant to fully integrate with the fusing bone. It also has best-in-class X-ray compatibility, which allows me to track my patients’ progress with more confidence.”
John O’Toole (Department of Neurosurgery, Rush University Medical Center, Chicago, USA), one of the first surgeons to implant the Fortilink-TS device, adds, “The introduction of TETRAfuse 3D Technology revolutionises the interbody device market by combining a favourable 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.”
The Fortilink-L IBF System is intended for a lateral transpsoas approach to the lumbar spine: lateral lumbar interbody fusion (LLIF) surgeries. The Fortilink-TS System is intended for traditional posterior approaches: 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, a company press release states.
RTI commercially launched its first implant using TETRAfuse 3D Technology, the Fortilink-C IBF System, in October 2017. It is used as an interbody fusion device in anterior cervical discectomy and fusion (ACDF) surgeries. All Fortilink implants have received 510(k) clearance from the US Food and Drug Administration (FDA).
