Secondary mobilization of the first dorsal metacarpal artery flap for first web space reconstruction in a child: A case report

Abstract

The authors report the case of an iterative mobilization of a skin flap based on the first dorsal metacarpal artery. This flap was initially associated with a toe-to-hand transfer to provide adequate skin coverage in the reconstruction of a post-traumatic thumb defect in a 5-year-old child. More than 8 years after initial surgery, this flap was mobilized again for recovery of the first web space opening, which was retracted. This case illustrates the possibility of remobilizing the first dorsal metacarpal artery flap to reduce donor site sequelae in children.
