A subtrochanteric fracture is defined by its major portion of at least 2/3 which must be situated underneath the mid-part of the trochanter minor. Stabilization of subtrochanteric fractures technically does not differ from treatment of pertrochanteric fractures. The intramedullary device used for treatment is usually sufficient to bear strains occurring during the mobilization period. There is a major difference between these fracture types, though.

Subtrochanteric fractures often coincide with a not sufficiently stable proximal femur shaft. This expected instability will cause the nail to tilt in AP direction within bolt axis. This movement may cause an increase of postoperative pain. This study investigates movement of given nail types. This should help to decide which nail to use.
