Osteomyelitis is inflammation of bone. It is usually caused by bacteria but occasionally by fungi. Osteomyelitis in children has a mainly hematogenous origin; less commonly, it occurs as a result of trauma, surgery, or spread from infected contiguous soft tissue. Osteomyelitis due to vascular insufficiency is rare in children.
