Chiropodists and podiatrists are medical practitioners, certified or uncertified, those perform the diagnosis, assessment, and treatment of ankles, feet, and rest of the lower legs. They are certified to tend people with arthritis, nail surgery, diabetes, sports injuries, corns, verrucas, etc. Technically chiropodists are not different from podiatrists, the difference in name is as a result of difference in the regional nomenclature of medical practices of Europe and American states. In the U.S they are generally known as podiatrists, whereas in Europe they are known as chiropodists. Their practice segment comprises people of all ages but with the growing complications including diabetes, etc, and wearing joints, the geriatric population forms a majority of the patient segment.
