When is curettage and cautery recommended for corns and calluses?

A corn or callus is thickened skin produced by repeated pressure or friction. Curettage removes built-up tissue with a specialised instrument, while cautery uses controlled heat to treat the selected area and help control bleeding. The procedure does not correct the shoe pressure or foot alignment that caused the thickening.

It may be discussed when ordinary pressure relief, footwear changes, cushioning, or careful filing have not solved a painful area, or when the thickened tissue makes walking difficult. The clinician must distinguish it from a wart, ulcer, infection, or another foot problem.

Arrange an examination before attempting to cut a deep corn or callus. Mention diabetes, reduced sensation, circulation problems, anticoagulant medicines, allergies, and any prior foot wounds.

Keep the treated site protected and follow dressing instructions. Reduce pressure with suitable footwear or padding, because untreated friction can cause the thickening to return. Avoid self-cutting, especially when sensation or circulation is reduced.

Seek prompt assessment for warmth, spreading redness, drainage, an open crack, sudden swelling, severe pain, or a darkened area. A foot wound needs timely attention when diabetes, poor circulation, or reduced sensation is present.

Ask what pressure source needs correction, whether the thickened area is a corn, callus, or another lesion, how to protect the wound, and which footwear or padding changes can prevent recurrence.
