Dorsal digital arteries of foot

The dorsal digital arteries of the foot are small blood vessels that supply blood to the toes. These arteries are branches of the dorsalis pedis artery and the arcuate artery, which are themselves branches of the anterior tibial artery.

Anatomy

The dorsal digital arteries originate from the dorsalis pedis artery and the arcuate artery. They run along the dorsal (top) surface of the foot, extending towards the toes. Each toe receives two dorsal digital arteries, which run along the sides of the toe, providing oxygenated blood to the tissues.

Function

The primary function of the dorsal digital arteries is to supply oxygenated blood to the tissues of the toes. This is crucial for maintaining the health and function of the toes, as well as for the overall circulation in the foot.

Clinical Significance

The dorsal digital arteries can be involved in various medical conditions, such as peripheral artery disease (PAD), which can lead to reduced blood flow and ischemia in the toes. Injuries to the foot, such as fractures or lacerations, can also damage these arteries, leading to complications such as bleeding or impaired healing.
