Origin
The dorsal digital arteries arise from the dorsal metatarsal arteries at the level of the metatarsophalangeal joint. Each dorsal metatarsal artery divides into two dorsal digital arteries.
Course
The dorsal digital arteries run along the medial and lateral aspects of adjacent digits. The first and fifth dorsal metatarsal arteries run distally along the medial aspect of the great toe and the lateral aspect of the little toe, respectively.
Branches
There are no named branches.
Supplied Structures
The dorsal digital arteries give cutaneous, muscular, and articular supply to the dorsal aspect of the digits of the foot. In particular, they contribute to the supply of the dorsal interossei, the lumbricals, and the extensor digitorum brevis muscles.

Artery
When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
