Causes of Osteomyelitis

Bacteria or rarely a fungus multiply on the bone and causes infection:

Bacteria travel to the bone via the bloodstream, such as staphylococci spreading from a boil or other skin infection or following an injury that leads to an infection e.g. a deep cut, a broken bone or surgery to a bone.

Your risk of developing osteomyelitis increases if you: 

  •  have recently broken a bone or had surgery affecting a bone, 
  •  are diabetic, 
  •  have had your spleen removed, 
  •  are having kidney dialysis, 
  •  are an intravenous drug user, 
  •  have a problems with your immune system, (for example HIV or sickle cell disease).

Osteomyelitis can be caused by the tuberculosis (TB) bacterium. This often affects the vertebrae (spinal bones).
