DePuySynthes - Titanium Fixation Nail (TFN)

The Titanium Trochanteric Fixation Nail (TFN) System permits an intramedullary approach for the fixation of fractures of the femur. The TFN System consists of a series of cannulated nails, cannulated helical blades, cannulated femoral neck screws, cannulated end caps, and locking bolts and screws. All of the implants in the TFN System are made of titanium alloy.
The helical blade provides improved resistance to varus collapse and rotational control of the medial fracture segment compared to single screw fixation (i.e., lag screws). The result is superior life-to-cut-out versus single screw fixation. This is accomplished through the use of the 11.0 mm helical blade. In addition, the use of the 11.0 mm helical blade results in reduced bone removal versus use of a traditional hip screw. These helical blade features are especially advantageous in osteoporotic fracture fixation. However the TFN system also offers a lag screw fixation using an 11.0 mm femoral neck screw.
