Foot Blood Supply
Quick Answer: Foot blood supply via dorsalis pedis (top), posterior tibial (inside), and peroneal (outer) arteries. We palpate these pulses during exam. Loss of pulses suggests peripheral arterial disease (PAD).
Why We Check Pulses
Strong pulses = healthy circulation. Weak/absent pulses = need vascular workup. Critical for diabetic foot exams.
FAQ
Is no dorsalis pedis pulse normal?
15% of people congenitally lack DP pulse. Posterior tibial should be present.
