When Your Child Has Osteomyelitis

What causes osteomyelitis?

Germs such as bacteria and fungi can cause osteomyelitis. The most common type of bacteria that causes osteomyelitis is called Staphylococcus aureus or staph. The bacteria and fungi can enter the body through:

• Infected wounds or joints

• Infections that spread from another part of the body

• Broken bones that break through the skin

• Foreign object that breaks the skin

Those at higher risk for bone infection include children:

• With no spleen

• Who are on dialysis

• With sickle cell disease

• Being treated with immunosuppressive medicines such as chemotherapy

• Who have diabetes

But any child can get this infection. In some cases, the cause of the infection is never known.

What are the symptoms of osteomyelitis?

If your child has any of these symptoms, get medical help right away.

• Fever of  100.4°F ( 38°C) or higher, or as advised by your child's provider

• Chills

• Pain in the bone

• Swelling of the arms or legs

• Redness or warmth of the skin on the arms or legs

• Pus draining from the skin

• Not letting the arms or legs be touched

• Not using the arms or legs (limb unable to hold weight)

• Babies could be irritable or lethargic, refuse to eat, or vomit.

An infection often happens from a recent injury. Symptoms of the infection are masked by the symptoms of the injury. Because of this, it might take longer to notice the infection. It's important to bring your child to their healthcare provider if symptoms don't get better quickly.

How is osteomyelitis diagnosed?

If the healthcare provider thinks your child may have osteomyelitis, these tests may be done:

• X-ray of the area to look for infection

• Blood tests to confirm infection and find the germ causing the infection

• Imaging tests such as a bone scan, CT scan, MRI, or ultrasound

• Biopsy (procedure to take a sample of bone) to find the germ causing the infection

How is osteomyelitis treated?

At first, treatment often takes place in the hospital. The treatment may include:

• Antibiotic or antifungal medicines, given through an IV (intravenous) line or by mouth (oral)

• Pain medicine

• Surgery to clean out infected area in and around the bone

Your child may be given antibiotics for 4 to 6 weeks. This can be done using a PICC line (peripherally introduced central catheter) at home. In other cases, your child may be able to have oral antibiotics. This will depend on how they've responded and the specific germ causing the infection.

Long-term concerns

Most children recover completely. Although rare, complications can occur. They include:

• Blood clots

• Growth problems

• Abnormally shaped bones

• Broken bones (fractures)

• Joint stiffness

• Death of bone tissue
