The aim of this study was to analyze the arterial supply of the sesamoid bones of the hallux. Twenty-two feet from adult cadavers were injected with epoxide resin or an acrylic polymer in methyl methacrylate (Acrifix) and subsequently processed by two slice plastination methods and the enzyme maceration technique. Afterwards, the arterial supply of the sesamoid bones was studied. The first plantar metatarsal artery provided a medial branch to the medial sesamoid bone. The main branch of the first plantar metatarsal artery continued its course distally along the lateral side of the lateral sesamoid and supplied it. The supplying arteries penetrated the sesamoid bones on the proximal, plantar, and distal sides. The analysis and cataloging of the microvascular anatomy of the sesamoids revealed the first plantar metatarsal artery as the main arterial source to the medial and lateral sesamoid bones. In addition, the first plantar metatarsal artery ran along the lateral plantar side of the lateral sesamoid bone, suggesting that this artery is at increased risk during soft-tissue procedures such as hallux valgus surgery.
本研究旨在分析拇趾籽骨的动脉供应情况。对来自成年尸体的22只足注射环氧树脂或甲基丙烯酸甲酯中的丙烯酸聚合物（Acrifix），随后采用两种切片塑化方法和酶浸软技术进行处理。之后，对籽骨的动脉供应进行研究。第一跖底动脉向内侧籽骨发出一支内侧分支。第一跖底动脉的主要分支沿外侧籽骨的外侧继续向远端走行并为其供血。供血动脉从近端、足底和远端穿入籽骨。籽骨微血管解剖结构的分析和编目显示，第一跖底动脉是内侧和外侧籽骨的主要动脉来源。此外，第一跖底动脉沿外侧籽骨的足底外侧走行，这表明在诸如拇外翻手术等软组织手术过程中，该动脉面临的风险增加。
