Wound healing consists of a cascade of interrelating reactions triggered by an injury. Any disruption to the cascade could lead to delay or non-healing. A chronic wound frequently has multiple etiologies.
It is estimated that 1-2% of the U.S. population will have a chronic wound at some time during their life. The number of these wounds, the cost of their treatment, and their impact on an individual’s quality of life and independence is almost certain to grow with aging and the increasing incidence of obesity in our population.
