What is secondary osteomyelitis?
In adults, osteomyelitis is usually a subacute or chronic infection that develops secondary to an open injury to bone and surrounding soft tissue. The specific organism isolated in bacterial osteomyelitis is often associated with the age of the patient or a common clinical scenario (i.e., trauma or recent surgery).
What is the most common cause of acute osteomyelitis?
Most cases of osteomyelitis are caused by staphylococcus bacteria, types of germs commonly found on the skin or in the nose of even healthy individuals. Germs can enter a bone in a variety of ways, including: The bloodstream.
Can you be misdiagnosed with osteomyelitis?
Misdiagnosis can lead to recurring chronic osteomyelitis, the need for amputation, or even death in more severe cases.
How would osteomyelitis appear radiographically?
Chronic osteomyelitis A fragment of dead infected bone becomes separated from viable bone and is known as a sequestrum. The bacteria within the devascularised sequestrum are protected from antibiotics and the endogenous immune response, thus forming a nidus for chronic infection which may persist for many years (1).
What is the prognosis for osteomyelitis?
Outlook / Prognosis With proper treatment, the outcome is usually good for osteomyelitis, although results tend to be worse for chronic osteomyelitis, even with surgery. Some cases of chronic osteomyelitis can be so resistant to treatment that amputation may be required; however, this is rare.
How quickly does osteomyelitis spread?
Acute osteomyelitis develops rapidly over a period of seven to 10 days.
What does osteomyelitis pain feel like?
This pain is usually described as dull or aching and may worsen during activity. The person may also experience fever and night sweats. In addition to pain, some cancerous bone lesions can cause stiffness, swelling, or tenderness in the affected area. The pain may come and go and may be worse or better at night.
What happens if osteomyelitis is untreated?
Osteomyelitis is a bacterial, or fungal, infection of the bone. Osteomyelitis affects about 2 out of every 10,000 people. If left untreated, the infection can become chronic and cause a loss of blood supply to the affected bone. When this happens, it can lead to the eventual death of the bone tissue.
What are the complications of osteomyelitis?
Some of the complications of osteomyelitis include:
- Bone abscess (pocket of pus)
- Bone necrosis (bone death)
- Spread of infection.
- Inflammation of soft tissue (cellulitis)
- Blood poisoning (septicaemia)
- Chronic infection that doesn’t respond well to treatment.
What is the mortality rate of osteomyelitis?
weeks after onset of spinal symptoms; diagnosis was confirmed within the first month of illness for 69% of patients, and the mortality rate was 11.7%. Patients with impaired immune systems appeared to be at increased risk of death.
What are common local signs of osteomyelitis?
The symptoms of osteomyelitis can include:
- Pain and/or tenderness in the infected area.
- Swelling, redness and warmth in the infected area.
- Nausea, secondarily from being ill with infection.
- General discomfort, uneasiness, or ill feeling.
