Santa Clara, California-based Si-Bone designed TNT to address the anatomic and biomechanical challenges of pelvic fragility fractures. It particularly helps in patients with poor bone quality, offering a significant advancement over traditional cannulated screws.

TNT received FDA 510(k) clearance and FDA breakthrough device designation in August. Si-Bone said it’s the first 3D-printed transiliac-transsacral screw cleared for market use in the U.S. It features a pelvis-specific design to improve initial fixation and reduce the risk of screw backout.
