Question 1

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

Accepted Answer

Proliferative phase

Answer

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

Question 2

What is the appropriate ankle-brachial index (ABI) threshold below which elective foot surgery should generally be deferred?

Accepted Answer

ABI less than 0.5

Answer

An ABI below 0.5 indicates severe peripheral arterial disease and is a relative contraindication to elective foot surgery due to poor healing potential.

Question 3

Which debridement method uses sterile maggots (larvae) to selectively remove necrotic tissue from chronic wounds?

Accepted Answer

Biologic (larval) debridement

Answer

Biologic (larval) debridement uses Lucilia sericata maggots that selectively digest necrotic tissue while sparing viable tissue.

Question 4

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

Accepted Answer

Nylon (non-absorbable monofilament)

Answer

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 5

Which complication of wound healing is characterized by excessive collagen deposition that extends beyond the original wound margins?

Accepted Answer

Keloid formation

Answer

Keloids extend beyond the original wound margins due to uncontrolled collagen deposition and are more common in darkly pigmented individuals.
