Lower extremity ulcers, such as venous and arterial ulcers, can be complex and costly and can cause social distress. An estimated 1% of the adult population is affected by vascular wound types, and 3.6% of those affected are older than 65 years of age. Many factors contribute to lower extremity wound chronicity, including venous disease, arterial disease, neuropathy, and less common causes of metabolic disorders, hematological disorders, and infective diseases. A total of 15% to 20% of lower limb ulcers have a mixed etiology.
