Correction of thumb deformities after burn: Versatility of first dorsal metacarpal artery flap

Patient 1. (A) Pre-operative view of the hand; burn contracture that cause severe deformity. (B) Flap design: the skin island of the flap lies over the proximal phalanx of the index finger. (C) The flap was elevated on pedicle including FDMA, superficial dorsal vein and a terminal branch of dorsal sensory branches of the radial nerve. (D) The harvested island flap was transposed onto the defect through a skin tunnel and donor site is resurfaced with a skin graft. (E, F) Post-operative view at 6 months following the operation.

Patient 8. (A) Deformity of the thumb due to the burn. (B) Corrective arthorodesis was also performed. (C) Appearance of the hand immediately after the surgery; the flap cover the ulnar site of the finger and donor area was covered with skin graft. (D) Appearance of the thumb at post-operative 6 months.

Patient 4. (A) Burn contracture that causes severe deformity on distal phalanx of the thumb. (B) Post-operative view of the thumb; deformity was corrected with FDMA flap.
