SI Joint Fusion

The SI joint can be a significant cause of lower back pain. Clinical publications have identified the SI joint as a pain generator in 15-30% of chronic lower back pain patients.1-4 In addition, the SI joint is a pain generator in up to 43% of patients with continued or new onset lower back pain after a lumbar fusion.5

iFuse TORQ® is designed to stabilize and fuse the SI joint. The iFuse procedure involves inserting typically three threaded titanium implants across the SI joint to maximize stability, reduce pain, and improve function. The procedure is done through a small one-inch incision and takes about an hour. The 3D-printed iFuse TORQ implant was designed for osseointegration, which is the structural and functional connection between implant and bone. This allows your painful joint to be stabilized through binding of bone all along the implant.6
