This chapter focuses on ulcer and its management. This chapter covers the ulcer, venous ulcers, arterial ulcer, diabetic ulcer, examination of diabetic foot, decubitus ulcer, wound assessment, and physiotherapy management of wound/ulcer. Ulcer is defined as a break in skin or mucous membrane with loss of surface tissue, disintegration and necrosis of epithelial tissue, and often pus. Ulcer is a type of chronic wound, which occurs as a result of an underlying or internal etiology. Venous ulcers are wounds that are thought to occur because of improper functioning of venous valves, usually of the legs (hence leg ulcers). Definition of chronic venous leg ulcer is defined as an open lesion between the knee and ankle joint that remains unhealed for at least 4 weeks and occurs in the presence of venous disease. An ulcer caused by diminished blood flow through an artery, especially the one that nourishes a finger or toe is called arterial ulcer. Management of arterial ischemic ulcers classically includes conservative debridement, pain control, use of occlusive dressings, and improvement of circulation.
