Currently, cephalomedullary nails are used widely for reverse obliquity fractures because they limit medialization of the shaft fragment unlike sliding hip screws.

The Haidukewych et al study quoted demonstrated the superiority of fixed angle devices such as blade-plates or dynamic condylar screws over the sliding (or dynamic) hip screws. Reverse obliquity intertrochanteric fractures of the femur are recognized as biomechanically different from standard intertrochanteric fractures. The rate of failure of internal fixation for this fracture pattern was higher than the rates in most reports of internal fixation of intertrochanteric fractures devices.
