Dorsalis Metatarsal Arteries, Dorsal View

Description

Running distally across the dorsum of the male foot, the dorsalis metatarsal arteries course in the intermetatarsal spaces between adjacent metatarsal shafts, superficial to the dorsal interossei and aligned toward the metatarsophalangeal joints. Proximally, these vessels arise from the dorsal arterial arch, the continuation of the dorsalis pedis artery across the tarsus, then divide into dorsal digital branches that track along the toes. Surrounding osseous landmarks include the phalanges, metatarsals, and tarsal bones, with articular cartilage at the interphalangeal, metatarsophalangeal, and tarsometatarsal joints; accompanying superficial dorsal veins run in parallel but are shown in blue for clear artery vein separation. Dorsal metatarsal artery anatomy matters when you need to think about perfusion to the forefoot, where small caliber vessels and limited collateral flow can turn minor trauma into tissue loss. This dorsal perspective supports planning for dorsal incisions over the second to fourth metatarsals, where careless dissection can compromise dorsal digital branches and complicate wound healing, skin graft take, or fixation exposure. It also clarifies the source of the dorsal toe pressures used in vascular assessment, and why dorsalis pedis patency does not always guarantee robust distal digital perfusion. Teach from it in lower limb anatomy and podiatric medicine courses when students are learning to map surface pulses to deeper branches and to relate vessels to metatarsal intervals and joint lines. It also suits textbooks, perioperative patient education, and clinical reference content for diabetic foot management, forefoot osteotomy approaches, and flap design on the dorsum.
