The human foot is a complex structure. It contains 26 bones plus muscles, nerves, ligaments, and blood vessels. Podiatrists diagnose and treat disorders, diseases, and injuries of the foot and lower leg. They treat foot conditions such as corns, calluses, ingrown toenails, and bunions. They also treat ankle and foot injuries as well as foot complaints associated with diseases such as diabetes.
Podiatrists use laboratory tests and X-ray images to diagnose diseases and deformities.
They fit corrective devices and help design corrective shoes. They may prescribe drugs and therapy. Some podiatrists specialize in surgery, bone disorders, or foot problems of very young or very elderly patients. They often refer patients to other specialists. Most podiatrists are in private practice.
