●Unique united interlocking nail design: provide stability and anti-rotation capability; the pressing effect is remarkable in the process of screwing in the compression screw.

● Distal screw holes can select dynamic or static interlocking. The screws can be hold with hex screwdriver 5mm. 

● The main nail has a deflection angle of 5 °, which is easy to insert from the top of the large trochanter. 

●  It is divided into short nail and long nail and provide lag screw and compression screw. 

●    Integrated interlocking screws (lag and compression screw) provide effective stability and linear pressure.

Preloaded end cap allows for creation of a fixed angle device, reduces the

●  difficulty of intraoperative operation and ensures the dynamic of the fracture site.

●  Distal elasticity of the main nail reduces stress shielding of the distal femur,so as to reduce potential distal femoral fractures.

Main nail’s proximal trapezoid interlocking nail can make femoral proximal more stable. 

Hairpin bifurcation design of the distal of main nail is to reduce stress concentration and to avoid distal periprosthetic fracture.
