What is it indicated for?

The short length Elos nails are intended for stabilizing various types of intertrochanteric fractures of the femur. The long length Elos nails are intended for fixation of femoral fractures occurring from the base of the femoral neck extending distally to a point approximately 10 cm proximal to the intercondylar notch. Fracture types include basilar neck, intertrochanteric, subtrochanteric fractures and femoral shaft fractures. These femoral fractures may occur as a result of trauma, non-union, malunion, pathological fractures, and impending pathological fractures.
