1. A method for bi-planar wedge osteotomy of a foot, comprising the steps of:
providing a cut guide comprising a body having a first face, a second face opposite the first face, and defining a slot extending from the first face to the second face that is suitable for guiding a blade;
the body defining a row of holes extending from the first face to the second face, the row of holes arranged parallel to the slot and having an alignment opening extending parallel to the first face, the alignment opening arranged perpendicular to the slot and configured to receive a radiopaque member;
inserting a first wire at least into a first bone of the foot, so that the first wire is distal from tissue to be removed;
inserting a second wire into a second bone of the foot, so that the tissue to be removed is distal from the second wire;
pivoting the cut guide about the first wire, until a first axis of the cut guide is parallel with a longitudinal axis of a first metatarsal of the foot;
inserting a third wire through the cut guide, so as to fix the cut guide to the first bone while the first axis of the cut guide is aligned with the longitudinal axis of the first metatarsal;
cutting bone through the slot while the cut guide is fixed by the first and third wires, to form a first planar cut into or through bone material;
pivoting the cut guide about the second wire, until the first axis of the cut guide is aligned with the longitudinal axis of the talus;
inserting a fourth wire through the cut guide, so as to fix the cut guide to the second bone while the first axis of the cut guide is aligned with the longitudinal axis of the talus; and
cutting bone through the slot while the cut guide is fixed by the second and fourth wires, to form a second planar cut into or through bone material.
