Shape-modified radial forearm flap: does it still have a role in upper extremity reconstruction?

Abstract

ObjectivesTo carry out a radial forearm flap, the radial artery is usually harvested, incurring severe donor site morbidity. Advances in anatomical knowledge discovered constant radial artery perforating vessels, enabling the subdivision of the flap into smaller components suitable for a wide range of differently shaped recipient sites, with marked reduction of downsides. Material and methodsEight pedicled or free shape-modified radial forearm flaps were used to reconstruct upper extremity defects between 2014 and 2018. Surgical technique and prognosis were examined. Skin texture and scar quality were assessed on the Vancouver Scar Scale while function and symptoms on the Disabilities of the Arm, Shoulder and Hand score. ResultsAt a mean follow-up of 39 months, no cases of flap necrosis, impaired hand circulation or cold intolerance were found. ConclusionThe shape-modified radial forearm flap is not a new technique, but is poorly known by hand surgeons; in contrast, our experience showed it to be reliable, with acceptable functional and esthetic outcomes in selected cases.
