In one embodiment, the bone engagement surface 922 may have a cuneiform apposition portion 932 shaped to lie against a surface (such as a dorsal surface) of the medial cuneiform 202, and a metatarsal apposition portion 934 shaped to lie against a surface (such as a dorsal surface) of the first metatarsal 208. As illustrated, the cuneiform apposition portion 932 may be contoured to match the contour of the dorsal surface of the cuneiform on which it is to rest, and the metatarsal apposition portion 934 may similarly be contoured to match the contour of the dorsal surface of the metatarsal on which it is to rest. Thus, the navigation guide 900 may have only one stable position and orientation relative to the cuneiform and the metatarsal. Alternatively, or in addition, the cuneiform apposition portion 932 may be contoured to match the contour of a surface that is between the dorsal surface and a medial or lateral surface and/or the surface includes at least a portion of the dorsal surface of the cuneiform on which it is to rest, and the metatarsal apposition portion 934 may similarly be contoured to match the contour of a surface that is between the dorsal surface and a medial or lateral surface and/or the surface includes at least a portion of the dorsal surface of the metatarsal.
