What is osteomyelitis?
Osteomyelitis is 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 (computed tomography) or MRI (magnetic resonance imaging)
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.
What causes osteomyelitis?
Usually bone infections are caused by bacteria that:
Spread from nearby infected skin
Enter through a deep wound over a bone
Less often the bacteria:
Travel through your bloodstream from an infection in another part of your body
Enter when a broken bone has punctured the skin
Are a complication of bone or joint surgery
