The length is consistent with the anatomy of the FEMORAL medullary cavity.

To further improve the fixation strength of osteoporosis. The Blunt End Design of the locking screw reduces the risk of excessive penetration.

Short nail: diameter of 8.0 / 9.5mm, length of 160mm.
Long nail: diameter of 7.0 / 8.5mm, length of 180-315mm (15mm interval).
All nails have left and right type, titanium alloy material. The diameter is suitable for all applications. Simple operation and minimally invasive implantation.

Multi-plane and Multi-locking screw fixation options, multiple options for operation, to achieve optimal fixation stability. Screw-in-screw design to further improve the fixation strength of osteoporosis. Blunt head of locking screw design to reduce the risk of excessive penetration. Locking screw countersinking design to reduce soft tissue irritation.

Short screw: two different plane holes for locking.
Long screw: three locking holes avoid important blood vessels, located in the safe area between the median nerve and the radial nerve. Two anterior and posterior locking holes facilitate the manual operation, minimizing the occurrence of rotation and displacement of distal fracture.

Nail diameter should be 30-40% of the narrowest transverse diameter of medullary cavity.
Recommended application sizes by age:
- 3.0mm: 6-8 years old
- 3.5mm: 9-11 years old
- 4.0mm: 12-14 years old

Special design of compression holes helps to increase the stability of transverse or short oblique fractures. Self-sustaining compression mechanism, no static screw is needed to maintain compression during operation.

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.
