背景资料：本研究的目的是识别第五跖骨的滋养动脉，并确定小囊泡截骨术如何损伤该血管。方法：通过钡注射和增强计算机断层扫描对10具成人下肢进入第五跖骨的滋养动脉进行了研究。结果：滋养动脉从远侧斜行入第五跖骨内侧，位于中、近三分之一交界处结论：本研究揭示了滋养动脉进入第5跖骨的方向和位置，为临床提供了解剖学依据。(C)2017年欧洲足踝协会。由爱思唯尔有限公司出版。保留所有权利。
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 degrees) 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 degrees).Conclusions: This report revealed direction and location of the nutrient artery entering the fifth metatarsal.
