Osteomyelitis is an infection of the bone. The infection may be:
Acute (for a short time) Chronic (lasting over a long period of time)
In adults, the pelvis and vertebrae (bone of the back) are the most common sites. In children, the long bones are most likely to be affected. These are found in arms and legs.
This infection can occur as a result of an injury to the bone, or an infection in the body carried by the blood.
