Multi-plane and Multi-locking screw fixation options provide multiple surgical routes to achieve optimal fixation stability. Features a screw-in-screw design to further improve the fixation strength of osteoporosis. The blunt head of the locking screw design reduces the risk of excessive penetration, while the countersinking design minimizes soft tissue irritation.

Short screw: Two different plane holes for secure locking.
Long screw: Three locking holes avoid key blood vessels, placed in the safe zone between the median nerve and radial nerve. Two anterior and posterior locking holes facilitate manual operation, minimizing rotation and displacement of distal fractures.

The nail diameter should remain between 30% and 40% of the narrowest transverse diameter of the medullary cavity. Recommended guidelines:
• 3.0mm: for ages 6-8 years old.
• 3.5mm: for ages 9-11 years old.
• 4.0mm: for ages 12-14 years old.

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

Compared with G3 featuring a radian radius of 1.5m, the distal location of TFNA with a radian radius of 1.0m in the center of the medullary cavity is twice as likely to achieve optimal anatomical alignment.
