Abstract
A wedge osteotomy method inserts a first wire into a first bone of the foot, distal from tissue to be removed. A second wire is inserted into a second bone, so the tissue to be removed is distal from the second wire. A cut guide is pivoted about the first wire, until a first axis of the cut guide is parallel with a longitudinal axis of the first metatarsal. The cut guide has a slot perpendicular to the first axis for guiding a cutter to cut bone, while the first axis is aligned with the longitudinal axis of the first metatarsal. The cut guide is then pivoted about the second wire, until the first axis is aligned with the longitudinal axis of the talus, and bone is cut through the slot, to form a second planar cut into or through bone material.
