Spineology Launches First-of-Its-Kind Duo Ti™ Expandable Interbody Fusion Procedure

Duo Ti offers one of the least invasive lateral approaches and Spineology’s proprietary mesh technology with OsteoSync™ Ti porous titanium blocks

Spineology Inc., an innovator in anatomy-conserving surgery, is excited to launch the Duo TiExpandable Interbody Fusion Procedure, which combines Spineology’s proprietary mesh technology with porous titanium to deliver a large, anatomy conforming implant via anatomy-conserving lateral decubitus and prone approaches. The porous titanium blocks are made from OsteoSync™ Ti (SITES Medical) and feature a highly porous macro structure with micro and nano-texturing, and a low modulus of elasticity to facilitate superior bone ingrowth capabilities.

“In my experiences with Duo, my patients recover quickly following surgery, return to activities timely, and show durable long-term relief”

Spineology will be demonstrating this technology at the 2021 North American Spine Society (NASS) conference Sept. 29-Oct. 2 in Boston, Massachusetts. The company is also hosting an Innovation Lab at NASS at 11 a.m. Thursday, Sept. 30.

The Duo Ti procedure is performed through a small portal tube. Following insertion of the implant, the mesh component is filled and expanded with bone in situ which enables surgeons to reduce retraction requirements, avoid and protect neural structures, and indirectly decompress. The result for patients and care providers is enhanced recovery, proven outcomes backed by Spineology’s 200-patient Duo Clinical Study (RaDical), and exceptional efficiency.¹

• Enhanced Recovery: According to RaDical, subjects did not experience clinically meaningful new onset or increased thigh symptoms (i.e., pain, hip flexion/extension weakness) following the Duo procedure. Less trauma to the psoas muscle decreases or eliminates the risk of indirect nerve root injury and may accelerate patient recovery.
• Proven Outcomes: At three months, individual patients in the RaDical study showed a 71 percent improvement in their lower extremity pain and 57 percent improvement in their low back pain. At 12 months, 98 percent of patients had fused.
• Exceptional Efficiency: Duo can be performed as a single-position prone procedure which eliminates the need to flip a patient intraoperatively and saves surgeons operative time, which can lead to overall reduced procedure costs.

“In my experiences with Duo, my patients recover quickly following surgery, return to activities timely, and show durable long-term relief,” said Dr. Pierce Nunley of Shreveport, Louisiana. “Because of the minimal psoas muscle manipulation, and the outcomes I see in my patients treated with Duo, this is the superior lateral procedure for these indications.”

When the implant is inserted during a Duo procedure, porous titanium blocks generate distractive forces capable of restoring disc height and spinal alignment, and providing indirect decompression. After insertion, the mesh component is filled with bone to create a large, endplate-conforming, load-sharing graft pack that can reduce risk of subsidence and support bony ingrowth leading to fusion over the entire surface area of the implant.²

“The exposure-to-footprint ratio I experience with Duo is exceptional. Duo has enabled me to minimize exposure and subsequently provide my patients very minimal hospitalizations. This is very beneficial for these trying Covid times and bodes well for the use of the technology long-term in the outpatient setting,” said Dr. Larry Khoo of Los Angeles, California.

Spineology CEO John Booth remains dedicated to anatomy-conserving technologies like Duo. “I am pleased to announce such a minimally disruptive approach for lateral spine surgeons,” he said. “Recent macro events have increased the need for spine surgery to become even more minimally invasive. Our new Duo system will lead the way for lateral surgeons who want to offer their patients all of the advantages of less-invasive surgery.”
