Direction and location of the nutrient artery to the fifth metatarsal at risk in osteotomy for bunionette

Publication date: Available online 29 October 2017 Source: Foot and Ankle Surgery Author(s): Ichiro Tonogai, Fumio Hayashi, Yoshihiro Tsuruo, Koichi Sairyo 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°)
