Abstract

Dorsal hand reconstruction with radial artery perforator-based adipofascial flap

Highlights

Soft tissue defects of the dorsal hand are commonly caused by relatively high-energy trauma such as industrial accidents
Free vascularized flap transplantation is the ideal procedure because the major vessels in the zone of injury that may have been damaged, and the vascular supply of the flap and affected limb can be reconstructed using a flow-through method[1]
The radial artery perforator based adipofascial flap is a versatile flap that is safe and easy to elevate without sacrificing the radial artery[7,8]

Summary

INTRODUCTION

Soft tissue defects of the dorsal hand are commonly caused by relatively high-energy trauma such as industrial accidents In such cases, free vascularized flap transplantation is the ideal procedure because the major vessels in the zone of injury that may have been damaged, and the vascular supply of the flap and affected limb can be reconstructed using a flow-through method[1]. The posterior interosseous flap is an effective option[5,6] This flap enables covering the dorsal hand defect with well-vascularized tissue without sacrificing major vessels, it requires surgeons to perform fine and burdensome procedures. As contrastenhanced computed tomography after hand replantation surgery revealed an incomplete palmar arch, the combination of a radial artery perforator adipofascial flap and split-thickness skin graft was selected. Skin and soft tissue defects were observed, in addition to exposure of the second metacarpal bone head on the dorsal side
