Many patients ask:
What is the difference between a podiatrist and an orthopedist?
The short answer is that both podiatrists and orthopedists perform surgery on the foot and ankle. This is similar to neurosurgeons and orthopedists both performing back surgery or dermatologists and plastic surgeons both performing cosmetic surgery.
Yet there are some distinctions in choosing a podiatric surgeon for your foot and ankle care:
- While being the same 4 year length as osteopathic (DO) and allopathic (MD) medical school and covering the same basic and clinical sciences, the podiatric medical school curriculum provides additional intense focus on conditions of the foot, ankle and lower leg.
- Podiatric surgeons typically complete 3 years of intense residency training in complex foot and ankle surgery. General orthopedists who desire to pursue additional training in foot and ankle surgery typically complete a 1 year fellowship.
- As Fellows of the American College of Foot & Ankle Surgeons, podiatric surgeons remain among a group of the only physicians who are Board Certified in Foot Surgery and/or Reconstructive Rearfoot Surgery.
Acrocyanosis is a painless disorder that affects the arteries supplying blood to the skin of the hands and feet. These small arteries carry oxygen and nutrients through the blood to the skin of the extremities. Spasms in the arteries block blood flow in people with this condition. Without adequate blood supply, the skin lacks oxygen, which changes the skin color to a dark blue to purple color. This characteristic color is called cyanosis.
Acrocyanosis is generally a benign condition, but can be indicative of a serious medical illness elsewhere in the body, such as cardiovascular or connective tissue disease. It occurs more frequently in women than in men. Symptoms include feet that are persistently cold in temperature, blue skin discoloration, sweaty or moist skin, and swelling.
Treatment focuses on keeping the foot warm and the blood circulating normally. It may include wearing insulated boots, thin polypropylene liner socks to wick the moisture away from the skin, and/or use of an insulated sock to maintain normal skin temperature. The disorder itself cannot be remedied, but does not worsen over time.
