case_images: Open wounds were observed at the base of the right thumb with partial necrosis of the surrounding skin (Figure 1).
case_images: (a) The fracture in the first metacarpal shaft (arrow) is visible on the radiograph taken at the patient's first visit to our hospital. (b) The fracture was fixed by cross-pinning.

case_images: Plain radiography of the right hand revealed a fracture of the first metacarpal shaft (Figure 2(a)). Irrigation, debridement, and fixation of the first metacarpal fracture were immediately performed during the first visit to our hospital (Figure 2(b)).
case_images: (a) A skin defect was observed in the dorsum of the hand and the first web space. Arrowheads show the extensor pollicis longus. (b) Intraoperative photograph shows the reverse posterior interosseous artery (PIA) flap before dissection of the PIA (white arrowhead). Black arrowhead shows the posterior interosseous nerve. (c) Patient outcome 1 year postoperatively.

case_images: The skin defect was 3.3 cm x 6 cm (Figure 3(a)). After identifying the PIA (Figure 3(b)), it was dissected and ligated proximal to the dominant perforator. Subsequently, the patient discontinued MINO and remained recurrence-free with a favorable prognosis (Figure 3(c)).
case_images: Bone union of the first metacarpal bone (arrow) is visible on a radiograph taken 1 year after the injury.
