Objective To provide anatomical foundation for clinical application of themedial pedis perforator flap. Methods The number，length，origin， exteriordiameter and anastomosis of the perforators of the medial plantar artery which were distributed to the area of medial pedis were observed and measured on 8 adult fresh lower limb specimens perfused with red latex. Results The blood supply of the medial pedis area included medial plantar artery, medial anterior malleolar artery, medial tarsal arteries and tibia toe lateral artery. 5.3 perforators in average were identified in the medial intermuscular septum between abductor hallucis and flexor digitorum brevis, which were sent out to the non weight bearing area of medial plantar aspect. Among these the first and second perforators were larger and longer in external diameter and length of pedicle. The medial branches of medial plantar deep artery sent out cutaneous branches to the medial pedis area at (1.92±0.61) cm ahead of Scaphoid tuberosity. The tibial artery of hallux went through to the medial pedis area at (2.03±0.56) cm proximal to the fist plantar toe joint and formed anastomotic arch on the abductor muscle. Conclusions The medial pedis perforator flap can be designed as pedicle flaps for resurfacing defects around the heel and forefoot, and free perforator flaps can be harvested forresurfacing pulp defects of digits.
