Definition

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.

    Causes

    Osteomyelitis is caused by specific bacteria.

  • Diagnosis

    Your doctor will ask about your symptoms and medical history. A physical exam will be done.

    Your bodily fluids and tissues may be tested. This can be done with:

        
  • Blood tests
  • Bone biopsy
  • Images may be taken of your bodily structures. This can be done with:

        
  • X-ray
  • Bone scan
  • CT scan or MRI scan
  • Treatment

    The affected area may be treated with a splint to prevent it from moving. Avoiding weight bearing activities may also be advised.

    Antibiotics

    This infection is treated with antibiotics. They are given by IV and sometimes by mouth. Acute osteomyelitis is generally treated for at least 4-6 weeks. Chronic osteomyelitis may require antibiotics for a longer period of time.

    Surgery

    Surgery may be required to:

        
  • Clean infected bone via scraping and irrigating the area
  • Remove any fragments of dead bone or tissue that may prolong the infection
  • In severe cases, amputation may be necessary.

    Skin Graft

    In some situations, your doctor may recommend a skin graft . The skin in the affected area is replaced with healthy skin taken from another part of your body.

    Prevention

    To reduce your risk of getting osteomyelitis:

        
  • Seek immediate medical care for infections or injuries.
  • Keep diabetes under good control.
  • Do not use illegal drugs.
  • See your doctor for any sores that do not heal.
  • If you smoke, talk to your doctor about how you can successfully quit.
