Anatomy, Bony Pelvis and Lower Limb: Foot Arteries

Excerpt

The vasculature of the foot is composed of arteries that originate from the anterior and posterior tibial arteries, the terminal branches of the popliteal artery. The posterior tibial artery is said to be the stronger branch of the two, as it is considered a continuation of the main trunk. The anterior tibial artery produces arteries that supply the dorsum of the foot, while the posterior tibial artery produces arteries that supply the plantar aspect of the foot.

This article will review both dorsal and plantar foot vasculature in detail, discuss its embryonic origin, and touch on its relevance to peripheral arterial disease (PAD) and the clinical physical exam. The intrinsic foot muscles supplied by these arteries will be briefly discussed as well.
