This type of ulcer generally occurs in elderly people that have neglected to maintain calluses and corns, or have tried to treat callus with corn plasters. as the callus thickens it adds to the trauma and pressure on an area that may start to break down. If ignored, it will ulcerate. Poor Circulation may reduce the potential to heal.
Treatment involves removing the callus build up, protecting the area after dressing with anti-septic ointments.
Sometimes these ulcers are infected and Anti-biotics are necessary.
Once the wound has healed a regular maintenance program for keeping the pressure sites under control may be necessary.
