Podiatry, or podiatric medicine, is a branch of medicine devoted to the study of, diagnosis, and medical and surgical treatment of disorders of the foot, ankle and lower extremity. The term podiatry came into use in the early 20th century in the United States and is now used worldwide, including countries such as the United Kingdom and Australia. Podiatry is practiced as a specialty in many countries, while in many English-speaking countries, the older title of chiropodist may be used by some clinicians (not to be confused with chiropractic, which is unrelated). In Australia, the title is podiatrist or podiatric physician and the specialist is the podiatric surgeon. In many non-English-speaking countries of Europe, the title used may be podologist or podólogo.
