FIG. 20 illustrates one example of a cutting guide 1900 coupled to the bones using a proximal bone attachment feature 1952 and a distal bone attachment feature 1954. In the illustrated embodiment, the proximal bone attachment feature 1952 includes at least one hole 1950 and a fastener and the distal bone attachment feature 1954 includes at least one hole 1950 and a fastener. In FIG. 20 the fasteners are K-wires. Advantageously, the proximal bone attachment feature 1952 and the distal bone attachment feature 1954 each include at least two holes 1950, each with a K-wire passing through the hole 1950 and into bone facing the inferior side 1922. Using two holes 1950 and two fasteners ensures a stable coupling between the cutting guide 1900 and the bone(s). Advantageously, in certain embodiments, the two holes 1950 of the proximal bone attachment feature 1952 and distal bone attachment feature 1954 are align such that inserted K-wires are parallel to each other. Among other benefits, parallel K-wires of each of the proximal bone attachment feature 1952 and distal bone attachment feature 1954 prevent the cutting guide 1900 from pivoting around one of the K-wires of a proximal bone attachment feature 1952 or a distal bone attachment feature 1954.
