case_images: X-ray images revealed hypoplasia of the metacarpal bone and the defective CMC joint of the right thumb (Figure 2).
case_images: The metatarsal bone cut hemilongitudinally: (a) the cut metatarsal bone and (b) radiograph after the removal of the fourth metatarsal bone.

case_images: During surgery, the left fourth metatarsal bone was cut hemilongitudinally from the head to the shaft and the lateral part was removed (Figures 3(a) and 3(b)).
case_images: The metatarsal bone transplanted into the metacarpal bone. (a) The metacarpal bone and the cut metatarsal bone were sutured. (b) These were fixed with a Kirschner wire.

case_images: The epiphyseal line was observed, and the metacarpal bone grew to approximately 28 mm in length within 2 years of surgery (Figure 5(a)). Moreover, readily notable growth disorder of the donor toe was not observed (Figures 5(b) and 6(b)).
case_images: Two years after surgery: (a) hand and (b) foot.
