1. A method for removing a prosthetic hip stem from a bone comprising:
drilling a channel through the bone at a first surface location on the bone adjacent to the prosthetic hip stem such that the channel extends from a proximal end to a distal end of the prosthetic stem, the channel defining a longitudinal first axis;
drilling a hole at a second surface location on the bone separate from the first surface location, the hole being formed along a second axis through the bone adjacent to the distal end of the prosthetic hip stem such that the channel and the hole intersect;
inserting a first end of a cutting wire through the channel and the hole; and
cutting an interface between the hip stem and the bone with the cutting wire.
