What is osteomyelitis?

Osteomyelitis is a severe bone infection. It can develop in any bone, but often involves the long bones, such as your arm and leg bones, or the bones of the spine. Osteomyelitis is caused by different types of germs, such as bacteria or a fungus.

What increases my risk for osteomyelitis?

  • Recent trauma or surgery
  • Poor blood flow to your arms or legs
  • Weak immune system
  • Medical conditions, such as diabetes, sickle cell anemia, or a prosthetic implant
  • A central vein or dialysis catheter
  • Age older than 50
  • Poor nutrition
  • IV drug abuse

What are the signs and symptoms of osteomyelitis?

  • Fever
  • Pain, redness, and swelling
  • Trouble moving or putting weight on your limb
  • Bruising or discoloration
  • Pus coming from a wound or sore
  • Night sweats
  • A bone that looks out of place

How is osteomyelitis diagnosed?

  • Blood tests are used to show the type of germ causing the infection.
  • X-ray, CT, or MRI takes pictures of your bone and tissue to look for infection and damage. You may be given contrast liquid to help the bone and tissue show up better. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.
  • A bone scan shows diseased or damaged bones. A radioactive liquid, called a tracer, is given through an IV. The tracer collects in your bones so problems show up better in pictures.
  • A bone biopsy takes a sample of your bone to learn what is causing your infection. It can also help healthcare providers learn how to best treat the infection.

How is osteomyelitis treated?

You may need any of the following:

  • Medicine will be given to fight the infection and to decrease pain or fever.
  • Hyperbaric oxygen therapy may be needed to help the wound heal. During therapy your infected bone is exposed to a high amount of oxygen.
  • Surgery may be needed to drain or remove the infected, damaged, or dead bone tissue. Screws, pins, or a graft may be placed. A limb may be amputated if the bone infection spreads or becomes severe.

Talk to your healthcare provider before you use these products.
  • Manage other medical conditions , such as diabetes, to prevent more bone damage.

When should I seek immediate care?
