The Gross Anatomy of the Dorsalis Metatarsal Arteries of a Human Male

Description

Across the dorsum of the male foot, the dorsalis pedis artery continues distal to the ankle joint and gives rise to the dorsalis metatarsal arteries as they course anteriorly over the metatarsus. Each dorsalis metatarsal artery runs in the intermetatarsal space, positioned superficial to the dorsal interossei and deep to the extensor tendons, then divides near the metatarsal heads into dorsal digital branches for adjacent toes. Proximally, the talus and calcaneus anchor the hindfoot, while the metatarsals and phalanges define the forefoot framework laterally and medially around the first ray. Small arterioles and accompanying veins track alongside the arterial trunks. Clear pathways. Dorsal metatarsal arterial anatomy matters when you need to understand distal perfusion and safe corridors on the dorsum of the foot. Pedal bypass planning and interpretation of duplex ultrasound or CTA often hinge on whether flow is maintained through the dorsalis pedis and into the dorsal metatarsal network, and distal emboli can present with toe ischemia despite an apparently palpable dorsalis pedis. On the operative side, dorsal incisions for metatarsal osteotomy, Lisfranc exposure, or extensor tendon procedures cross the same intermetatarsal intervals, where injury to a dorsalis metatarsal artery can compromise digital supply and complicate wound healing. For teaching, the plate supports lower limb gross anatomy, podiatric anatomy, and surgical approaches modules by pairing osseous landmarks, extensor tendons, interosseous muscles, and the dorsal arterial tree in a single field. It also fits vascular surgery or diabetic foot publications where authors need an accurate map of dorsalis metatarsal arteries relative to the metatarsal heads and interosseous spaces.
