The TFN is a new cannulated, intramedullary nail system. It is indicated in stable and unstable fractures of the proximal femur including pertrochanteric, intertrochanteric, basal neck fractures, as well as a combination thereof.

BISON™ Trochanteric Fixation Nailing (TFN) System is designed to treat unstable, comminuted, proximal fractures of the femur, specifically, the intertrochanteric and subtrochanteric regions. The Lag Screw design offers superior cutting behavior during Lag Screw insertion, providing extremely low insertion torque.

With an outcomes-based design 1 and reduced procedural complexity 2, it’s designed to meet previously unmet surgical needs in hip fracture treatment. The TFN-ADVANCED Nailing System is a part of the Advanced Nailing System from DePuy Synthes and has features that allow surgeons to address proximal femur fractures. The system includes:

The trochanteric femoral nail advanced (TFNA) device is an intramedullary nail that uses a spiral blade or lag screw to obtain fixation in the femoral head. The operative technique for other cephalomedullary devices is generally similar, but it is important to review the manufacturer’s guides for details.

Improved Nail Strength. Titanium Alloy and BUMP CUT™ Design: Provides improved fatigue strength when compared with existing nails of similar size. 5* Small Proximal Diameter and LATERAL RELIEF CUT Design: Small proximal diameter of 15.66mm and lateral relief cut leading to a better fitting implant. 2,6-8. © DePuy Synthes 2023.

Author has emphasized the small radius of curvature of TFN-A closely matches the native femoral bow and thus reduces anterior cortical impingement and blowout.

The Trochanteric Fixation Nail-Advanced (TFN-A; Synthes GmbH, Oberdorf, Switzerland) is a titanium alloy implant which derives primarily from the Trochanter Fixation Nail (TFN) and Proximal Femoral Nail Antirotation (PFNA and PFNA-II) families of implants.

The trochanteric fixation nail (TFN) is intended for the treatment of stable and unstable pertrochanteric, intertrochanteric, basal neck fractures, and combinations thereof.

The TFNA System is designed to advance the treatment of trochanteric fractures by providing surgical options that help to preserve bone in insertion area due to reduced critical width, improve anatomical fit 1 and increase implant strength. 2 It is designed to reduce the risk of cut-out, 3,4 distal cortical impingement 1 and nail breakage, 2 whi...

chanteric and subtrochanteric regions. The Lag Screw design offers superior cutting behavior during Lag Screw insertion, pr. viding extremely low insertion torque. The Locking Blade design offers excellent grip in the cancellous bone of the femoral head.
