Advantageously, the illustrated embodiment the resection features 2022 include open ends (e.g., open dorsal end 2070, open plantar end 2074, open dorsal end 2078, and open plantar end 2082). The open ends end able a surgeon to manipulate or tilt a cutting tool from a normal orientation relative to the slot to an angled position that moves the cutting tool out past the perimeter of the resection guide 2020a. For example, a surgeon can insert a cutting tool in posterior dorsal slot 2058 and cut bone below the posterior dorsal slot 2058. In addition, the surgeon can angle the cutting tool in a plantar direction and the posterior dorsal slot 2058 guides the cutting tool to cut outside the perimeter of the resection guide 2020a. In particular, moving the cutting tool in a plantar direction enables a cutting blade of the cutting tool to cut bone dorsal to, but still aligned with the posterior dorsal slot 2058. In this manner, the surgeon can create an osteotomy that extends dorsally beyond a dorsal cortex of the bone. Similarly, and in like manner, the open plantar end 2074, open dorsal end 2078, and/or open plantar end 2082 enable the surgeon to form an osteotomy that reaches to the other dorsal and/or plantar surfaces of the bone. These open ends allow the resection guide 2020 to be smaller (not as long along its longitudinal axis) such that smaller incisions are needed for use.
