iFuse TORQ TNT™
Pelvic Bone Density-Driven Design1
iFuse TORQ TNT™ Implant: the first 3D-printed, porous, threaded implant with lengths capable of spanning the posterior pelvis, passing through the ipsilateral ilium, sacrum, and through the contralateral ilium (through and through, "TNT").
Features
- Pelvis-Specific 8.7 mm Diameter Fits 95% of S1 corridors suitable for a 7.3 mm transsacral screw2. 150% stronger in bending vs 7.3 mm stainless steel screw3, 4
- FuSlon 3D™ Surface 3D Printed Porous Lattice Designed for osseointegration5
- Self-Drilling, Self-Tapping Decreases surgical steps
- TORQLock™ Threads Hooked Profile Designed to reduce toggle
Designed to reduce loosening through pelvis-specific fixation. Variable thread heights and leads tailored to the posterior pelvis.
Case Studies
-
Brian Cunningham MD “Pelvic insufficiency fractures will be one of the great challenges for our generation. Traditional thinking, care pathways, and surgical technology will not be the solution. We need innovation in how we diagnose and treat these injuries, and we need innovative technology in the operating room designed specifically for these patients.”
Case: Sacral Fracture with Bilateral SI Joint Involvement Following Low-Energy Ground-Level Falls
