Pressure ulcers represent a major health problem causing both considerable morbidity and a high financial burden for the healthcare system. The geriatric segment of the population at risk of pressure ulcer is progressively increasing. This condition occurs at home, in old people's homes and in hospitals as well. The severity, duration and orientation of forces applied to the skin represent the most important factors responsible for pressure ulcers. Prevention measures are essential to reduce the prevalence of the disease.
