At present, there are several clinical concerns about femoral nails:
1. The incidence of distal femoral cortical bone impact is 25%, as the curvature of nail is not in accordance with the anatomical curvature of femur;
2. The incidence of blade incision in the femoral head is 8%, can lead to fixation failure and surrounding tissue damage or reoperation.

Features and Benefits of TFNA
At present, there are several clinical concerns about femoral nails: 1. The incidence of distal femoral cortical bone impact is 25%, as the curvature of nail is not in accordance with the anatomical curvature of femur; 2. The incidence of blade incision in the femoral head is 8%, can lead to fixation failure and surrounding tissue damage or reoperation; 3. The incidence of screw fracture is 5%, due to the design of week screw structure, which leads to prolonged healing time or nonunion.
Compared with G3 with radian radius of 1.5m, the distal location of TFNA with radian radius of 1.0m in the center of medullary cavity is twice as likely as that of G3.
The self-retaining design of aiming arm and nail can make the connection easier and faster. Pre-install locking device reduces the operation time during the operation, and makes the operation smooth. The cutting design of proximal lateral section of nail reduces the compression of nail on the lateral cortex.
The blade has the advantages of simple structure, high strength, and bevel design of tail end to reduce tissue irritation. The diameter of 10.35mm, length of 70 - 130mm (5mm interval), titanium alloy material.
There are four types of end caps: 0/5/10/15mm, titanium alloy material.
Smaller proximal diameter (15.66/15.5/16.25)
Short nail distal diameter of 9/10/12mm, length of 170/200/235mm, and proximal diameter of 15.66mm with external deviation 5°; Pre-installed locking device; Distal static locking: Collodiaphyseal angle of 125/130/135°; Locking screw diameter of 5.0 mm.
Long nail distal diameter of 9/10/11/12/14mm, proximal diameter of 15.66mm with external deviation 5° external deviation and radian radius of 1.0m, Pre-installed locking device; Distal dynamic locking with a locking range of 10mm; Blade anteversion angle of 10°; The distal locking hole is 10° away from the proximal locking hole (anterolateral - posteromedial) and is suited to the direction of the transverse axisof the femoral condyle.
