Osteomyelitis is an infection of the bone. The infection may be:
  • Acute—for a short time
  • Chronic—lasting for a long time
In adults, the pelvis and the bones of the back are the most common sites. In children, the long bones are most likely to be affected. These are found in the arms and legs.


Osteomyelitis is caused by specific bacteria.
