For example, in such instances, the distal bone attachment feature 1954 may serve as a reference for placement of a distal alignment feature 1990 (See FIG. 24A) that is parallel to the distal bone attachment feature 1954 as measured along the longitudinal axis 1976 of the first metatarsal 230. Subsequent to formation of a cut surface on the first metatarsal 230, the distal alignment feature 1990 can be coupled to the first metatarsal 230 in parallel to the distal bone attachment feature 1954 (e.g., by way of a pin guide). In certain embodiments, the distal alignment feature 1990 can include two or more aligned holes and/or a pair of K-wires that enter the bone in parallel to each other. In addition, in such a situation, the proximal alignment feature 1980 and the distal alignment feature 1990 may not be aligned initially. Instead, the proximal alignment feature 1980 and distal alignment feature 1990 may be configured to align when the bone coupled to the distal alignment feature 1990 is rotated. Fasteners 1956 of the distal bone attachment feature 1954 may be aligned with longitudinal axis 1976 and perpendicular to first slot 1960 by way of holes 1950. Fasteners 1956 of the proximal bone attachment feature 1952 may be aligned with reference line 1992 and perpendicular to second slot 1970 by way of holes 1950. The reference line 1992 may not be aligned with the longitudinal axis 1976.
