Osteomyelitis

Osteomyelitis is a bone infection caused by bacteria, a fungus or other germs. The most common cause of osteomyelitis is the Staphylococcus aureus bacterium, commonly called "staph."

There are several ways that bones can become infected:

  • Through a wound on the skin, muscles or tendons
  • After a fracture in which the ends of the bone pierce the skin
  • Through the bloodstream from an infection in another part of the body
  • After surgery on the bone, especially if the surgery involved placement of metal hardware
  • After an ear or sinus infection, if the infection spreads to surrounding bones or soft tissues (this is called skull base osteomyelitis)

Osteomyelitis symptoms

Symptoms of osteomyelitis might include the following:

  • Fever, sweating and chills
  • Bone pain or tenderness
  • Severe back pain
  • Swelling and redness at the infection site
  • Swelling of ankles, feet and legs
  • Lethargy, malaise or irritability

Symptoms of skull base osteomyelitis

A rare but serious condition, skull base osteomyelitis has its own unique set of symptoms, including the following:

  • Headaches
  • Pain around the eye or ear
  • Hearing loss or ringing in the ear
  • Dizziness
  • Facial weakness or paralysis
  • Double vision
  • Hoarseness
  • Difficulty swallowing

Osteomyelitis risk factors

Risk factors for developing osteomyelitis include the following:

  • Diabetes
  • Kidney disease
  • A past splenectomy
  • Intravenous drug use
  • A recent fracture, surgery or bone injury
  • A recent ear infection or sinus infection
  • Age (osteomyelitis is most common in older adults, especially those with diabetes)

Osteomyelitis differences in children and adults

Osteomyelitis tends to affect different bones in children and adults:

  • In children: the long bones of the arms and legs
  • In adults: the feet, hips, spine, ears and skull base (skull base osteomyelities is most common in older adults with diabetes)
