title: Vascular anatomy of the fifth metatarsal.
abstract: The extraosseous and intraosseous vascular anatomy to the fifth metatarsal as visualized in a group of below-the-knee amputation specimens has been described. The extrinsic circulation to the area is provided by the dorsal metatarsal artery, the plantar metatarsal arteries, and the fibular plantar marginal artery. These three source arteries supply branches to the metatarsal and adjacent joints. The intraosseous vascularity consists of a periosteal plexus, a nutrient artery, and a system of metaphyseal and capital vessels.
