case_images: Radiographic evaluation included assessment of hallux valgus angle (HVA), 1-2 intermetatarsal angle (IMA), proximal first metatarsal inclination angle (PFMI), and radiographic union (Figure 3). Both hallux valgus angle and 1-2 intermetatarsal angle have shown high intraobserver and interobserver reliability across multiple studies.   PFMI was selected as a measure of first TMT joint obliquity.   PFMI was measured as the angle between a line perpendicular to the axis of the second metatarsal and a line parallel to the proximal articular surface of the first metatarsal, which is easier to visualize than the articular surface of the medial cuneiform (Figure 3C).
case_images: (A) The dashed line represents the planned osteotomy that is made parallel to the metatarsocuneiform joint and extends across three-fourths of the width of the cuneiform. (B) A postfixation image is recommended to verify the reduction of the metatarsophalangeal joint and the sesamoids.

case_images: An osteotomy was made parallel to the TMT joint through approximately three-fourths of the width of the bone (Figure 4A). A final fluoroscopic examination was performed confirming reduction of the hallux metatarsophalangeal joint, sesamoid position, and osteotomy fixation (Figure 4B).
