A common post-operative complication of EPF is which of the following?

• A. Deep vein thrombosis
• B. Wound infection
• C. Urinary tract infection
• D. Calcaneal cuboid joint discomfort

Answer: (D)

After this type of hindfoot procedure, the most common localized problem is pain and discomfort at the calcaneocuboid (calcaneal-cuboid) joint. The surgery often involves manipulation or adjustment of the lateral column and the posterior facet of the hindfoot, which changes how the calcaneocuboid joint bears and transfers load. Postoperative swelling, scar tissue, and subtle shifts in alignment can increase contact stress or alter joint kinematics at this joint during weight-bearing. That combination—local tissue irritation around the joint plus altered mechanics—tends to produce the most frequent postoperative symptom in this scenario.

Systemic complications like deep vein thrombosis, wound infection, or urinary tract infection can occur after any surgery, but they are not the site-specific issue most closely tied to this procedure.
