As explained herein, the present disclosure enables fabrication of patient-specific instrumentation. FIGS. 9A-9C illustrate a patient-specific navigation guide 900 configured to guide a surgeon for an arthrodesis procedure on a tarsometatarsal (“TMT”) joint of a patient. Specifically, the navigation guide 900 may be configured with a body 906 that spans a TMT joint between a metatarsal bone (e.g., a first metatarsal 208) and a cuneiform (e.g., a medial cuneiform 202). Accordingly, the inferior side 918 is configured to interface with the cuneiform bone and the metatarsal bone of the patient. In particular, the bone engagement surface 922 and/or bone engagement opening 936 are configured to interface with surfaces the cuneiform and metatarsal (e.g., a dorsal surface of each bone). In the illustrated embodiment, the reference feature is the set of proximal guide pins 928 deployed in the cuneiform and the set of distal guide pins 930 deployed in the metatarsal.
