Patients walk across a plate connected to a computer that reads the patients' feet. From the computer readout, podiatrists may order the correct design. To diagnose a foot problem, podiatrists may order x rays and laboratory tests. Podiatrists consult with and refer patients to other health practitioners when they spot systemic diseases, such as arthritis, diabetes, and heart disease, of which first symtoms may appear in the foot. For example, diabetics are prone to foot ulcers and infections due to their poor circulation.
Most podiatrists have a general practice.
Some specialize in surgery, orthopedics, or public health. Besides these certified specialties, podiatrists may practice a subspecialty such as sports medicine, pediatrics, dermatology, radiology, geriatrics, and diabetic foot care. Podiatrists generally are in private practice, which means that they run a small business. They may hire employees, order supplies, and keep records. Most podiatrists are solo practitioners.
