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.

 



Magnetic resonance imaging (MRI) is sophisticated diagnostic equipment used to diagnose an array of health problems or conditions, including:

  • Arthritis.
  • Fractures.
  • Infections.
  • Injuries of the tendons, ligaments, or cartilage.
  • Tumors.

MRIs use no radiation like conventional X-rays or CT scans. They employ large magnet and radio waves to produce three-dimensional images. MRIs are very good at portraying soft tissues and bones in your feet and ankles.

People with the following conditions may not be good candidates for a MRI:

  • Conditions that requires a heart pacemaker.
  • Artificial heart valves.
  • Electronic inner ear implants.
  • Electronic stimulators.
  • Implanted pumps.
  • Metal fragments in eyes.
  • Surgical clips in the head (particularly aneurysm clips).

Individuals with dental fillings or bridges, a replacement hip or knee, or tubal ligation clips are generally safe to have a MRI.

In most cases, a full exam of the foot and ankle via MRI lasts between 60 and 90 minutes.
