Stability
Compression actively maintained to help stability and union.

A trapezoidal shape provides a press-fit in the metaphyseal region to position more material on the lateral side of the nail where tensile/stretching forces tend to be greatest.2
Integrated Compression Screws generate push/pull forces that are designed to hold compression after instrument removal and eliminate the Z-effect, with a worm gear mechanism converting rotation to active compression while stabilising the medial fragment.
Compression actively maintained to help stability and union.
Preservation of femoral offset to aid a return to function.
Anti-rotation to help preserve normal anatomy and biomechanics.
Optimisation of implant design to have strength where forces are highest.2
