Abstract：
OBJECTIVE: The aim of the study was to determine the flexion point\'s location of the ilio-femoral arterial axis and its angulation.
METHODS: Thirty-seven dynamic digital subtraction angiographies were analyzed and were included in the current study. Different lengths were measured, based on specific anatomical landmarks: the origin of the external iliac artery, the inguinal ligament and the bifurcation of the femoral artery. These lengths were measured in extension and during flexion of the hip in order to determine the flexion point of the artery.
RESULTS: In extension, some physiological angulations of the external iliac artery were measured. During flexion of the hip joint, the distance from the kink point to the bifurcation of the common iliac artery was respectively 82 ± 21 mm (range 48-116) on the right side and 95 ± 20 mm (range 59-132) on the left side. The distance from the kink point to the inguinal ligament was respectively 38 ± 40 mm (range 12-138) on the right side and 26 ± 23 mm (range 8-136) on the left side. The distance from the kink point to the bifurcation of the femoral artery was respectively 45 ± 29 mm (range 15-107) on the right side and 27 ± 12 mm (range 10-66) on the left side. During flexion, the angulation of the flexion point of the ilio-femoral axis was 114 ± 18° (range 81-136°).
CONCLUSIONS: The flexion point was located cranially to the inguinal ligament and below the departure of the external iliac artery.

摘要：
目的：本研究的目的是确定髂股动脉轴的屈曲点位置及其角度。
方法：对37例动态数字减影血管造影进行分析，并纳入本研究。测量了不同的长度，基于特定的解剖标志：髂外动脉的起源，腹股沟韧带和股动脉分叉。在髋部的伸展和屈曲期间测量这些长度,以便确定动脉的屈曲点。
结果：在扩展中，测量了髂外动脉的一些生理角度。在髋关节屈曲时,从扭结点到髂总动脉分叉的距离分别为右侧82±21mm(范围48-116)和左侧95±20mm(范围59-132)。从扭结点到腹股沟韧带的距离分别为右侧38±40mm(范围12-138)和左侧26±23mm(范围8-136)。从扭结点到股动脉分叉的距离分别为右侧45±29mm(范围15-107)和左侧27±12mm(范围10-66)。在屈曲期间，髂股轴屈曲点的角度为114±18°(范围81-136°)。
结论：屈曲点位于颅骨腹股沟韧带和髂外动脉的下方。
