Common digital arteries

Common digital arteries are arteries that supply blood to the fingers and toes. They are branches of the radial artery and ulnar artery in the hand, and the dorsalis pedis artery and plantar arteries in the foot.

Anatomy

The common digital arteries are located in the hand and foot. In the hand, they are derived from the superficial palmar arch, which is formed by the union of the ulnar artery and the superficial palmar branch of the radial artery. The common digital arteries typically divide into two proper digital arteries at the level of the metacarpophalangeal joints.

In the foot, the common digital arteries are branches of the plantar arch, which is formed by the union of the dorsalis pedis artery and the lateral plantar artery. They run along the sides of the toes, supplying blood to the skin, nails, and bones of the toes.

Function

The primary function of the common digital arteries is to supply oxygenated blood to the fingers and toes. This is crucial for the health and function of these structures, as they require a constant supply of oxygen and nutrients to function properly.

Clinical significance

Damage to the common digital arteries can lead to serious complications, including tissue necrosis and gangrene. This can occur as a result of trauma, vascular disease, or diabetes. In such cases, prompt medical attention is required to restore blood flow and prevent permanent damage.
