An innervated first dorsal metacarpal artery (FDMA) island‐flap reconstruction. (A), (B) A crush amputation of the total right thumb pulp with distal phalangeal bone exposure. (C), (D) An FDMA island flap with a sensory branch of superficial radial nerve (arrow) was elevated from the right index finger dorsum to reconstruct the amputated stump of the right thumb. (E), (F) The functional recovery and cosmetic results over the right thumb were good. The FDMA flap donor site was covered with a full‐thickness skin graft from the patient's groin region; it healed well.
