iFuse TORQ TNT™ Implant System
Pelvic Bone Density-Driven Design
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").
- 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 osseointegration3
- TORQLock™ Threads Hooked Profile Designed to reduce toggle
- FDA Breakthrough Device Designation The FDA determined iFuse TORQ TNT has the potential to provide more effective fixation of pelvic fragility fractures than the current standard of care, cannulated screws.
Bone Density-Driven Design
Designed to reduce loosening through pelvis-specific fixation.
Variable thread heights and leads tailored to the posterior pelvis.
