Bone infection can be caused by bacteria or fungi.
In children, the long bones are usually affected. In adults, the feet, spine bones (vertebrae), and the hips (pelvis) are most commonly affected.
Additional symptoms that may be associated with this disease:
A physical examination shows bone tenderness and possibly swelling and redness.
Tests may include:
The objective of treatment is to eliminate the infection and prevent it from getting worse.
Antibiotics will be given to destroy the bacteria that are causing the infection. You may be given more than one antibiotic at a time. Often, the antibiotics are given through an IV (intravenously, meaning through a vein) rather than by mouth. Antibiotics are taken for at least 4-6 weeks, sometimes longer.
Surgery may be needed to remove dead bone tissue if you have an infection that does not go away. If there are metal plates near the infection, they may be removed. The open space left by the removed bone tissue may be filled with bone graft or packing material that promotes the growth of new bone tissue.
Infection of an orthopedic prosthesis may require surgical removal of the prosthesis and infected tissue surrounding the area. A new prosthesis may be implanted in the same operation or delayed until the infection has gone away.
If the patient has diabetes, it will need to be well controlled. If there are problems with blood supply, surgery to improve blood flow may be needed.
When treatment is received, the outcome for acute osteomyelitis is usually good.
The outlook is worse for those with long-term (chronic) osteomyelitis, even with surgery. Amputation may be needed, especially in those with diabetes or poor blood circulation.
The outlook is guarded in those who have an infection of a prosthesis.
When the bone is infected, pus is produced within the bone, which may result in an abscess. The abscess steals the bone's blood supply. The lost blood supply can result in a complication called chronic osteomyelitis. This chronic infection can cause symptoms that come and go for years.
Other complications include:
Call your health care provider if you develop symptoms of osteomyelitis, or if you have osteomyelitis and the symptoms continue despite treatment.
Prompt and complete treatment of infections is helpful. High-risk people should see a health care provider promptly if they have signs of an infection anywhere in the body.
