On occasion, surgery is necessary to remove a bony prominence that causes the corn or callus. Hammertoes Hammertoes are one of several types of toe deformities. Hammertoes have a permanent sideways bend in the middle toe joint. Pain usually results over the prominent bony areas on the top of the toe and at the end of the toe. A hard corn may develop over this prominence.
Treatment usually involves a shoe to better accommodate the deformed toe.
Shoe inserts or pads may also help. If there are still problems after trying these treatments, surgical treatment to straighten the toe or remove the prominent area of bone may be necessary. Plantar warts Plantar warts occur on the sole of the foot and look like calluses. They are like warts elsewhere, but they grow inward. The wart cannot grow outward because of weight placed on it when standing.
