Podiatry is a field of healthcare devoted to the study and treatment of disorders of the foot, ankle, and sometimes knee, leg and hip (collectively known as the lower extremity). The terms podiatry and chiropody are not interchangeable, with the word chiropody being most used in the UK, and podiatry in the US.

History of Podiatry
The professional care of feet was in existence in ancient Egypt as evidenced by bas-relief carvings at the entrance to Ankmahor's tomb where work on hands and feet is depicted. Many Egyptologists believe tending feet probably spanned the whole of Egyptian civilization. The placement of carvings at the entrance of a tomb typically signified the profession of the buried individual and The Tomb of the Physician dates from 2400 BC.

Corns and calluses were described by Hippocrates who recognised the need to physically reduce hard skin, followed by removal of the cause. He invented skin scrapers for this purpose and these were the original scalpels. Celsus, a Roman scientist and philosopher was probably responsible for giving corns their name. Later Paul of Aegina (AD 615-690) defined a corn as "a white circular body like the head of a nail, forming in all parts of the body, but more especially on the soles of the feet and the toes. It may be removed in the course of some time by pairing away the prominent part of it constantly with a scalpel or rubbing it down with pumice. The same thing can be done with a callus."

Until the turn of the 20th century, chiropodists - now known as podiatrists or podiatric physicians - were separate from organized medicine. They are independently licensed physicians who treat the foot, ankle and related leg structures. Lewis Durlacher was one of the first people to recognise the need for a protected profession. He tried to establish the first association of practitioners in 1854, although it would take another century to come to pass.

There are records of the King of France employing a personal podiatrist, as did Napoleon. In the United States of America, President Abraham Lincoln suffered greatly with his feet and chose a chiropodist named Isachar Zacharie, who not only cared for the president’s feet, but also was sent by President Lincoln on confidential missions to confer with leaders of the Confederacy during the U.S. Civil War.

The first society of chiropodists was established in New York in 1895 with the first school opening in 1911. One year later the British established a society at the London Foot Hospital and a school was added in 1919. In Australia professional associations appeared from 1924 onwards. The first American journal appeared in 1907, followed in 1912 by an UK journal. In 1939, the Australians introduced a training centre as well as a professional journal. The number of chiropodists increased markedly after the Great War then again after World War II. Increased numbers of ex-soldiers needing to be gainfully employed gave chiropody a boost and led to the need for registration in all English speaking countries. The study of the foot i.e. podology, brought greater knowledge to the practice of foot care or podiatry.
