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.

 



Skin lesions refer to any variation in skin color or texture anywhere on the body. Some skin lesions are present at birth, such as moles, freckles, or birthmarks. Others are acquired over time, such as acne, warts, allergies, sunburn, or abrasions. Most skin lesions are harmless. However, it is important to keep an eye on them because they can change over time, which may be indicative of a serious problem. For example, one pigmented lesion that can occur on the foot and lower extremity is malignant melanoma.

A condition called actinic keratosis is another cancer-causing lesion that can occur on the feet. It is most commonly found in sun-exposed areas, such as the top of the foot. Treatment consists of freezing the lesions with liquid nitrogen or sharp excision.

Kaposi's Sarcoma is another cancerous lesion that may appear on the soles of the feet of people with HIV infection or AIDS. Kaposi's Sarcoma lesions are irregular in shape and have a purplish, reddish, or bluish-black appearance. They tend to spread and form large plaques or become nodular. The nodular lesions have a firm, rubbery appearance.
