Corns and calluses are NOT soft tissue problems and there is no "root" to be removed. No matter how much they are cut down or debrided, they will return. Painful corns and calluses are the result of abnormal position of the underlying bone. Often hammertoes become painful because inflammatory tissue will develop between the bone and corn or callus. This may treated with injections and anti-inflammatory medications.  If this relieves the symptoms then surgery can be delayed. If these treatments fail, then structural correction of the hammertoe is recommended by your physician.
