Features:
1. The proximal end is tapered to facilitate the insertion of the intramedullary nail and reduce the concentrated stress;
2. The proximal anatomical design is 4° varus, which is consistent with the ulna varus angle;
3. Various interlocking designs at the proximal end can solve different fracture types;
4. The distal blade is designed to provide anti-rotational stability when inserted into the metaphysis;
5. The locking hole thread design enhances the fixing effect.
