In the illustrated embodiment, the proximal arm 2230 includes the proximal bone attachment feature 2252 and the distal arm 2240 includes the distal bone attachment feature 2254. In one embodiment, the holes 2250 of the proximal bone attachment feature 2252 are aligned with each other and aligned perpendicular to a guide feature such as the second slot 2270 (see reference line 1992). The holes 2250 of the distal bone attachment feature 2254 may also be aligned with each other and aligned perpendicular to another guide feature such as the first slot 2260 (see reference line 1994). This means that the aligned holes 2250 (and K-wires secured within them) of the distal bone attachment feature 2254 will also be perpendicular to the cut surface formed using the first slot 2260. This also means that the aligned holes 2250 (and K-wires secured within them) of the proximal bone attachment feature 2252 will also be perpendicular to the cut surface formed using the second slot 2270. Consequently, at least one of the proximal bone attachment feature 2252 and the distal bone attachment feature 2254 can be used to position and orient a cut surface of the first metatarsal 230 and a cut surface of the first cuneiform 210. In certain embodiments, the proximal bone attachment feature 2252 and distal bone attachment feature 2254 may not be aligned with each other, the offset in the alignment may be the change in orientation of the bones of the joint desired to address the condition. It should be noted that the distal bone attachment feature 2254 may be parallel to the longitudinal axis 2276. In this manner, the distal bone attachment feature 2254 can be used as a reference for positioning a distal alignment feature 2290 on the first metatarsal 230.
