What is osteomyelitis?

"Osteo-" means bone, and "-itis" means inflammation.

Osteomyelitis is the medical term for a bone infection.

  • Bone is living tissue and can get infected like any other part of your body

  • Infection gets into a bone through your blood or from nearby infected tissue or an open wound

  • You may have pain in your bone, fever, and weight loss

  • You'll need x-rays and maybe a CT or MRI

  • You’ll need weeks of antibiotics and possibly surgery to treat osteomyelitis

With a bad infection, parts of the bone may die, which makes the infection harder to treat.

Sometimes the infection spreads out from your bone into nearby skin and muscle.
