There is no real difference. As of 1993, Chiropody changed its name to Podiatry, as it is the internationally recognised name for a foot specialist, and also more appropriate as podiatry encompasses a more modern approach to the profession, looking at pharmacology, biomechanics, orthotics, cortisone injections, nail surgery and foot surgery.
The profession, like its name, is constantly changing due to the extensive training given to students and the continuing education that enables podiatrists to treat a wide array of foot, lower limb and kinetic chain problems. As well as continuing to treat the more routine corns, callus, and nail care.
