Methods, systems and apparatuses including an assembly for changing an orientation of a first portion of a femur relative to a second portion of the femur are disclosed. The assembly can include an intramedullary nail and a jig. The intramedullary nail can be insertable into an intramedullary canal of both the first portion of the femur and the second portion of the femur. The intramedullary nail can have a first section disposed between a proximal end and a distal end thereof. The first section can have at least one surface that is angled relative to an axis of the intramedullary nail. The jig can be coupled to and rotatable about the intramedullary nail to change a rotational position of the first portion of the femur relative to the second portion of the femur.
