The lateral forearm flap versus traditional upper extremity flaps: A comparison of donor site morbidity and flap thickness

Introduction The lateral forearm flap (LFF) is a thin fasciocutaneous flap with a donor site that can be closed primarily. Methods A retrospective analysis of donor site morbidity and hand function was performed in patients who underwent a radial forearm flap (RFF), ulnar artery perforator flap (UAPF), or LFF. Flap thickness was evaluated radiographically in 50 control patients. Results Of 134 patients (lateral forearm flap: n = 49, RFF: n = 47, UAPF: n = 38), the LFF demonstrated significantly faster return to baseline hand grip strength (3 months vs. 12 months in RFF and UAPF; p
