case_images: The thumb and index fingers were completely amputated at the position of zone I and the middle finger was amputated at zone II (Figure 1).
case_images: A flap of 25 x 20 mm was made on the radial side at the base of the proximal phalanx of the right middle finger.

case_images: A flap of 25 x 20 mm was made on the radial side at the base of the proximal phalanx of the right middle finger (Figure 2), the vascular pedicle was ligated proximally after clamping to confirm finger blood circulation and isolated from the digital nerve, and the flap was elevated.
case_images: Since the dorsal branch of the digital nerve was identified in the middle phalanx, the flap was passed under the nerve to preserve it.

case_images: At the same time, the dorsal branch of the digital nerve was identified in the middle phalanx, and the flap was passed under the nerve to preserve the nerve (Figure 3).

case_images: In the Semmes-Weinstein monofilament test, the sensation of the flap returned to 3.22 (blue) and the dorsal sensation of the radial side recovered to 2.83 (green) early after surgery (Figure 4).
case_images: At half a year after the operation, there is no limitation on the range of motion, and the contour is also good.
