American Podiatric Medical Licensing Examination (APMLE) — Questions and Answers

Question 1: Which artery supplies blood to the plantar surface of the foot?

Dorsalis pedis artery
Anterior tibial artery
Fibular artery
Posterior tibial artery (Correct answer)

Correct answer: Posterior tibial artery

The posterior tibial artery is a major artery in the lower leg that descends behind the tibia. It gives off branches that supply the posterior compartment of the leg and then continues into the foot. Here, it branches into the medial and lateral plantar arteries, which are the main blood supply to the plantar (sole) surface of the foot.

Question 2: What type of suture material is preferred for skin closure in podiatric surgery due to its handling characteristics and knot security?

Nylon (non-absorbable monofilament) (Correct answer)
Silk (non-absorbable braided)
Polyglactin 910 (Vicryl, absorbable braided)
Chromic gut (absorbable natural)

Correct answer: Nylon (non-absorbable monofilament)

Nylon (e.g., Prolene or Ethilon) is commonly used for skin closure in podiatric surgery due to its low reactivity, strength, and easy removal.

Question 3: Which wound healing phase is characterized by fibroblast proliferation and collagen synthesis?

Remodeling phase
Hemostasis phase
Inflammatory phase

Correct answer: Proliferative phase

The proliferative phase (days 4–21) involves fibroblast migration, collagen synthesis, angiogenesis, and wound contraction.

Question 4: What is the most common organism responsible for diabetic foot osteomyelitis?
