Also known as: Bone infection
- Bacteria or other germs may spread to a bone from infected skin, muscles, or tendons next to the bone. This may occur under a skin sore.
- The infection can start in another part of the body and spread to the bone through the blood.
- The infection can also start after bone surgery. This is more likely if the surgery is done after an injury or if metal rods or plates are placed in the bone.
- You may receive more than 1 antibiotic at a time.
- Antibiotics are taken for at least 4 to 6 weeks, often at home through an IV (intravenously, meaning through a vein).
- If there are metal plates near the infection, they may need to be removed.
- The open space left by the removed bone tissue may be filled with bone graft or packing material. This promotes the growth of new bone tissue.

Osteomyelitis is a bone infection. It is mainly caused by bacteria or other germs.
Bone infection is most often caused by bacteria. But it can also be caused by fungi or other germs. When a person has osteomyelitis:
In children, the long bones of the arms or legs are most often involved. In adults, the feet, spine bones (vertebrae), and hips (pelvis) are most commonly affected.
Risk factors are:
Symptoms of osteomyelitis are not specific and vary with age. Main symptoms include:
Exams and Tests
A physical exam shows bone tenderness and possible swelling and redness in the area around the bone.
Tests may include:
The goal of treatment is to get rid of the infection and reduce damage to the bone and surrounding tissues.
Antibiotics are given to destroy the bacteria causing the infection:
Surgery may be needed to remove dead bone tissue if the above methods fail:
Infection that occurs after joint replacement may require surgery. This is done to to remove the replaced joint and infected tissue in the area. A new prosthesis may be implanted in the same operation. More often, doctors wait until the infection has gone away.
If you have diabetes, it will need to be well controlled. If there are problems with blood supply to the infected area, such as the foot, surgery may be needed to improve blood flow and get rid of the infection.
With treatment, the outcome for acute osteomyelitis is often good.
The outlook is worse for those with long-term (chronic) osteomyelitis. Symptoms may come and go for years, even with surgery. Amputation may be needed, especially in people with diabetes or poor blood circulation.
The outlook for people with an infection of a prosthesis depends partly on:
