Furthering Nevro's body of evidence as an innovation leader in pain management, data highlights the company's posterior integrated transfixation cage system

REDWOOD CITY, Calif., Nov. 18, 2024 /PRNewswire/ -- Nevro Corp. (NYSE: NVRO), a global medical device company that is delivering comprehensive, life-changing solutions for the treatment of chronic pain, today announced the publication of new data in Medical Devices: Evidence and Research, which demonstrate the superiority of the Nevro1™ SI Joint Fusion System ("Nevro1"), a posterior integrated transfixation cage system offering enhanced stability, minimized bone removal and increased fusion potential compared to a posterolateral cylindrical threaded single-implant system. Nevro1's performance also showed that it is equivalent in osteopenic bone when compared to a lateral triangular rod system in healthy bone.

The sacroiliac (SI) joints constitute two out of five joints within the spine-pelvic-hip complex and are responsible for facilitating load transfer to the torso and lower extremities.1-3 Joint dysfunction can arise from conditions such as degeneration, instability, infection or adjacent segment disease, causing significant pain and impacting daily activities like walking, sitting and lifting.4-6 Women, in particular, may experience pronounced discomfort and reduced quality of life due to SI joint pain.7-8

The study concurrently assessed and compared the fixation efficacy, invasiveness and fusion potential of a posterior integrated transfixation cage system (Nevro1) to the posterolateral threaded implant and lateral triangular rod systems.

Results concluded:

  • Nevro1 and the lateral triangular rods produced equivalent motion reduction in all motion planes.

  • Posterolateral cylindrical threaded implant produced less motion reduction than Nevro1 and lateral implants in flexion-extension.

  • Using Nevro1 for the treatment of SI joint-related pain allows for the most surface area for fusion, which provides a significantly better opportunity for robust SI joint arthrodesis.

"The SI joint is a recognized contributor to low back pain, significantly affecting daily life for those impacted," said Douglas Beall, MD, FIPP, FSIR, Chief of Services, Comprehensive Specialty Care, Clinical Radiology of Oklahoma. "This study demonstrates the advantages of the posterior integrated cage system that spans the SI joint to stabilize it and to address pain associated with SI joint dysfunction. The Nevro1 device represents a significant advancement in SI joint fusion, offering greater fixation with increased fusion potential, and minimal bone removal compared to other options I have for my patients."
