Anatomy basis and clinical application of the flap based on the perforator of plantar arch

Abstract

To report the anatomy basis and clinical application of the flap based on the perforator of plantar arch. From December 2013 to June 2016,25 cadaveric feet which were injected with a mixture of red gelatin were used to observe: the origins, courses, branches, distributions of the dorsal perforators flap based on the plantar arch; the anastomoses between the back perforators of plantar arch and rete arteriosum of dorsale pedis. Based on the anatomy research,11 cases with soft tissue defect at forefoot were treated with the perforator flaps. 11 flaps survived completely with primary healing. The flaps were followed up for 2-36 months with good match of texture and color. The flap based on the perforator of plantar arch has constant and rich blood supply. The technique is easily performed and can be used as an optional flap without major vessel for defect at forefoot.
