BACKGROUND
The aims of this study were to identify the artery feeding the fifth metatarsal and determine how bunionette osteotomy could injure this vessel.
METHODS
The nutrient artery entering the fifth metatarsal was investigated in 10 adult cadaveric lower limbs by barium injection and enhanced computed tomography.
RESULTS
The nutrient artery entered the medial aspect of the fifth metatarsal around the junction of the middle and proximal thirds obliquely from a distal direction (mean angle 36°) in the coronal plane in all cases; in the axial plane, the point of entry and direction of the artery was medial-plantar (mean angle 49°).
CONCLUSIONS
This report revealed direction and location of the nutrient artery entering the fifth metatarsal.
背景
本研究的目的是确定供应第五跖骨的动脉，并确定小趾囊炎截骨术如何损伤该血管。
方法
通过钡剂注射和增强计算机断层扫描，在10具成年尸体下肢中研究进入第五跖骨的滋养动脉。
结果
在所有病例中，滋养动脉在冠状面从远端以斜角（平均角度36°）进入第五跖骨中、近三分之一交界处的内侧；在轴位平面上，动脉的进入点和方向为内侧足底（平均角度49°）。
结论
本报告揭示了进入第五跖骨的滋养动脉的方向和位置。
