Abstract:
This case report describes details in treatment of a patient with a severed right upper arm and admitted to the Department of Microsurgery, Sichuan Modern Hospital in September 2024. The injury was caused by a piece of red-hot steel. In emergency surgery, the severed right upper arm was temporarily ectopically fostered in left distal leg. After 27 days of ectopic fostering, a stage-Ⅱ replantation surgery was performed to replant the ectopically fostered limb. A free anterolateral thigh perforator flap (ALTPF) was used to reconstruct the soft tissue defect on right arm after replantation. At 3 months of postoperative follow-up, the flap covering the right upper arm were soft in texture, without a sign of ulceration. Sensation was rated at S 2 on palmar side of first to third digits and as S 1 on palmar sides of fourth to fifth digits and dorsal sides of first to fifth digits. The active movement of the right wrist joint and the joints of the first to fifth fingers was not possible. The wrist joint was passively extended from 0° to 5°, passively flexed from 0° to 20°, the thumb had a passive total range of motion of 45°, the second to fourth fingers had a passive total range of motion of 70°, and the little finger had a passive total range of motion of 45°.
