Abstract Reconstruction of the distal leg, ankle, and foot is challenging, and local perforator flaps have emerged as valuable options. The aim of the present study was to evaluate the outcomes of local perforator flaps in the distal lower extremity. A total of 14 local perforator flaps were used in 12 patients (9 males [75%] and 3 females [25%], aged 19 to 83 years). The etiologies included 7 motor vehicle accidents (50%), 2 acute burns (14.29%), 2 chronic wounds (14.29%), 1 postburn contracture (7.14%), 1 gunshot wound (7.14%), and 1 malignancy (7.14%). The defects were localized to the mid-leg in 3 cases (21.43%), ankle in 4 (28.57%), calcaneus in 4 (28.57%), and foot in 3 (21.43%). A peroneal artery perforator flap (11 sites [78.57%]) or a posterior tibial artery perforator flap (3 sites [21.43%]) was used. Of the 14 flaps, 8 (57.14%) were fasciocutaneous, 4 (28.57%) were adipofascial, and 2 (14.29%) were adipose. The flap transfers were rotational in 9 cases (64.29%), flipped in 2 (14.29%), propeller in 2 (14.29%), and transcrural in 1 (7.14%). The flap dimensions ranged from 8 cm × 5 cm to 22 cm × 5 cm. Finally, 12 flaps (85.71%) remained viable, 1 (7.14%) had partially sloughed, and 1 (7.14%) had completely died owing to a hypercoagulable state. Overall, 13 flaps (92.86%) had good outcomes after a median follow-up period of 19 (range 12 to 37) months. Perforator flaps in the lower extremity are versatile in terms of size, design, composition, and axis of rotation. They are reliable and safe when used to reconstruct local defects.
