The length is consistent with the anatomy of the FEMORAL medullary cavity, ensuring structural alignment and functional efficiency.

Developed 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 types and are made of premium titanium alloy material. The diameter is suitable for all applications, supporting simple operation and minimally invasive implantation.

• Multi-plane and Multi-locking screw fixation options with multiple surgical operations to achieve optimal 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 minimize soft tissue irritation.

• Short screw: Features two different plane holes for locking stability.
• Long screw: Features three locking holes designed to avoid major blood vessels, located safely between the median nerve and radial nerve.
• Two anterior and posterior locking holes facilitate manual operations, minimizing distal fracture rotation and displacement.

Nail diameter should be 30-40% of the narrowest transverse diameter of the medullary cavity. Typical applications include:

• 3.0mm: Recommended for ages 6-8 years old
• 3.5mm: Recommended for ages 9-11 years old
• 4.0mm: Recommended for ages 12-14 years old

• Specialized compression holes structure designed to increase the stability of transverse or short oblique fractures.
• Self-sustaining compression mechanism eliminates the need for static screws to maintain active compression during operation.

Compared with G3 structures utilizing a radian radius of 1.5m, the distal location of TFNA with a radian radius of 1.0m inside the center of the medullary cavity is twice as likely to lock properly as that of G3.
