Arteries supplying the lateral aspect of the foot

The dorsalis pedis artery and its branches. (Lateral tarsal arteries not labeled, but visible at center right.)
Latin	Arteriae tarsales laterales

The lateral tarsal arteries are branches of the dorsalis pedis artery that supply blood to the lateral aspect of the foot. These arteries play a crucial role in the vascularization of the foot, particularly in the region of the tarsal bones.

Anatomy

The lateral tarsal arteries originate from the dorsalis pedis artery, which is a continuation of the anterior tibial artery. These arteries run laterally across the tarsal bones and anastomose with the arcuate artery and other branches of the dorsalis pedis artery.

Function

The primary function of the lateral tarsal arteries is to supply oxygenated blood to the lateral aspect of the foot, including the tarsal bones, ligaments, and surrounding tissues. This blood supply is essential for the proper functioning and health of the foot.

Clinical significance

Compromise or injury to the lateral tarsal arteries can lead to inadequate blood supply to the lateral aspect of the foot, potentially resulting in conditions such as ischemia or necrosis of the affected tissues. Proper vascularization is crucial for wound healing and the prevention of diabetic foot ulcers in patients with diabetes mellitus.
