Location and direction of the nutrient artery to the first metatarsal at risk in osteotomy for hallux valgus

Publication date: Available online 2 June 2017 Source: Foot and Ankle Surgery Author(s): Ichiro Tonogai, Keizo Wada, Kosaku Higashino, Yoshihiro Fukui, Koichi Sairyo Background Osteotomy for hallux valgus interrupts intraosseous blood supply to the first metatarsal, presumably causing non-union,delayed union, or osteonecrosis of the head of the first metatarsal. We investigated the first metatarsal nutrient artery, arising from the first dorsal metatarsal artery, and identified aspects of surgical technique contributing to nutrient artery injury. Methods Enhanced computed tomography scans of 8 feet of 8 fresh cadavers were assessed.
