The localization of nutrient foramina and direction of nutrient canals have been studied. However, information about the origin and extraosseous course of nutrient arteries is lacking in some types of long tubular and irregular bones. Thus, we aimed to reexamine the origin and course of the femoral nutrient artery (FNA) through cadaveric dissection to clarify its anatomic characteristics. Sixty thighs were collected from 57 cadavers. To fix the cadavers and visualize the small arterial branches, 10% formalin was injected from the femoral artery, followed by an injection of acrylic ink. The arterial tree in the posterior part of the thigh was recorded by line drawings. The femur received single or double FNAs via the femoral nutrient foramina, which were on and along the linea aspera. In cases with single FNA (41 of the 60 thighs), it typically arose from the four parts of the profunda femoris system: profunda femoris artery between the origins of the third and fourth perforating arteries; second perforating artery; third perforating artery; and terminal branch. In cases with double FNAs (remaining 19 thighs), the superior FNA typically arose from the second perforating artery, and the inferior FNA arose from the terminal branch of the profunda femoris artery and popliteal system. FNAs are described as branches of the perforating arteries in Terminologia Anatomica and anatomy textbooks. However, we found that FNAs also frequently arose from the profunda femoris artery and popliteal system, in addition to the perforating arteries. Clin.

已经研究了营养孔和营养管的方向。然而，在某些类型的长管状和不规则骨中，关于营养动脉的起源和骨外行程的信息是缺乏的。因此，我们旨在通过尸体解剖重新检查股动脉营养动脉（FNA）的起源和行程，以阐明其解剖学特征。从 57 具尸体中收集了 60 条大腿。为了固定尸体并可视化小动脉分支，从股动脉注入 10%的甲醛，然后注入丙烯油墨。通过线条图记录大腿后部的动脉树。股骨通过位于粗糙线和沿线的股骨营养孔接收来自单个或双 FNA 的营养。在有单个 FNA 的情况下（60 条大腿中的 41 条），它通常起源于股深动脉系统的四个部分：第三和第四穿动脉起源之间的股深动脉；第二穿动脉；第三穿动脉；和终末分支。在有双 FNA 的情况下（其余 19 条大腿），上 FNA 通常起源于第二穿动脉，下 FNA 起源于股深动脉和腘动脉系统的终末分支。在 Terminologia Anatomica 和解剖学教科书中，FNA 被描述为穿动脉的分支。然而，我们发现 FNA 也经常起源于股深动脉和腘动脉系统，除了穿动脉。临床解剖学 33:479-487,2020。2019 年 Wiley 期刊公司版权所有。
