An approach to leg and foot ulcers: a brief overview

Legs and feet are susceptible to ulcer formation. Three main types of lower extremity ulcers are venous, arterial, and neurotropic. Ulcer care should include treatment of the underlying cause, moist interactive healing, and quality of life (pain control). If the ulcer shows no signs of healing in 6 to 12 weeks, the wound should be biopsied, the diagnosis confirmed, and a plan of care instituted. In certain instances, biologicals may be used. A graphical representation of an approach to ulcer care, in addition to common differential diagnoses of leg ulcers, is presented.
