Anatomy Basis and Clinical Significance of Various Types of Abductor Hallucis Superior Margin Arterial Arcades
The aim of this study was to group arteries of arterial arch at the superior margin of the abductor hallucis muscle according to their constitutes and provide anatomical basis for reverse bifolicated flap based on it. The constitute, track-way and distribution of the artery, which supply the medial pedis flap, the medial plantar and the medial tarsal flap, especial the arterial arch at the superior margin of the abductor hallucis muscle were observed and analyzed on 81 lower limbs cast specimens and 2 fresh feet specimens. According to their constitute, arterial arch at the superior margin of the abductor hallucis muscle can be classified into 3 types: i) type I, It was constituted mainly by the branch of anterior medial malleolus artery and (or) the medial tarsal artery. ii) type II, It was constituted mainly by the superficial branch of the medial plantar artery; iii) type II, It was constituted mainly by the branch of anterior medial malleolus artery and the branch of medial tarsal artery anastomose with the superficial branch of the medial plantar artery, which was divided into two subtypes according to the different anastomosis of the artery: Type III 1, the type of anastomosed directly was about 48.2%, type III 2, The type of anastomosed indirectly was about 24.1%. According to the constitute of arterial arch at the superior margin of the abductor hallucis muscle can be classified into three types: The type of anterior medial malleolus artery and medial tarsal artery, the type of superficial branch of the medial plantar artery and the type of mixed. For the type mixed, two subtypes can be classified according to the different anastomosis of the artery.
