Corns and Callus
What is a Corn?
A corn is an area of hard skin over a pressure area. It is a defined circle, and over repeated pressure the hard skin forms an inverted cone shape. If the pressure is not relieved, the hard skin can press on the soft skin below to cause a wound, ulceration or infection.
What causes a Corn to form?
- Tight footwear
- Toe deformities, such as hammer toes
- Bony prominence
- Orthopaedic problems with feet or gait abnormalities
What can a Podiatrist do for you in clinic?
The podiatrist will remove any hard skin over the top of the corn and use a high speed water cooled drill to remove the corn itself. This is a painless procedure which in most cases will give immediate relief from symptoms. On very rare occasions corns can develop their own blood and nerve supply which can make them very painful to treat – these corns are removed under local anaesthetics.
What is Callus?
Callus is a larger plaque of hard skin, often discoloured with a slight yellow colour. When walking the feet take a lot of pressure, and naturally the skin toughens up in order to protect the underlying tissues. Over a period of time, the skin can build up to become too thick and cause a problem. In elderly patients or patients with certain medical conditions, there can be a depletion of the fatty padding of the feet, which also causes callus to build up.
What causes Callus?
The causes of Callus are similar to that of what causes a corn (as above)
What can a podiatrist do for you in clinic?
There are two main techniques to remove Callus. One is to use a small surgical knife called a scalpel and the other is a high speed water cooled drill. Neither is painful.
