From their About page:
It is estimated that more than 2 million people in the United States have lost a limb, either through trauma, disease or other medical condition. That number grows by an estimate of 185,000 each year. While many are combat veterans, just over half are amputees who have lost a limb due to vascular disease.
Mayo Clinic is undertaking a five-year program to develop, establish, and populate a national limb loss and preservation registry. The project is part of a competitive contract from the National Institutes of Health and Department of Defense. The goal is to collect data so this growing field of research and treatment can be based on reliable evidence.
