Study Demonstrates Advantages of Nevro1 SI Joint Fusion

Nevro announced study data which demonstrate the superiority of the Nevro1 SI Joint Fusion System, a posterior integrated transfixation cage 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 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 Nevro1 mechanism of stabilization consists of integrated transfixing titanium anchors, which are deployed bilaterally and pierce through the cortices of the ilium and sacrum to provide immediate axial and rotational stability of the joint. The proprietary implant design allows for a reduction in motion and abnormal stress on the SI joint without open surgery. Through a minimally invasive approach, the implant can be securely placed and may relieve pain and restore functionality to individuals suffering from chronic SI joint pain.
