What is anaerobic osteomyelitis?
What is anaerobic osteomyelitis?
Anaerobic osteomyelitis of the feet is usually associated with diabetes mellitus, severe trauma or other underlying diseases that can cause vascular insufficiency. Some investigators have noticed that, as the duration of chronic osteomyelitis lengthens, the number of isolated species of anaerobes increases [2,3].
Which is the most common causes of hematogenous osteomyelitis?
Acute hematogenous osteomyelitis usually occurs after an episode of bacteremia in which the organisms inoculate the bone. The organisms most commonly isolated in these cases include S aureus, Streptococcus pneumoniae, and Haemophilus influenza type b (less common since the use of vaccine for H influenza type b).
Why is hematogenous osteomyelitis common in children?
Acute hematogenous osteomyelitis (AHO) is particularly common in children <5 years of age and typically affects the metaphysis because of the rich but slow blood flow of the growing bone.
Does osteomyelitis ever go away?
Osteomyelitis is a painful bone infection. It usually goes away if treated early with antibiotics. If not, it can cause permanent damage.
What are the long term effects of osteomyelitis?
Chronic osteomyelitis can lead to permanent deformity, possible fracture, and chronic problems, so it is important to treat the disease as soon as possible. Drainage: If there is an open wound or abscess, it may be drained through a procedure called needle aspiration.
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.
Where does hematogenous osteomyelitis affect the bone?
From the initial metaphyseal focus, the infection can spread into the epiphysis, the joint space, the subperiosteal space, the soft tissues, and the shaft of the bone. Acute hematogenous osteomyelitis is an infection that usually affects the growing skeleton, involving primarily the most vascularized regions of the bone.
Is there a sex difference in hematogenous osteomyelitis?
The sex difference in infant osteomyelitis is not marked and in adult osteomyelitis is less than in the juvenile form. In infancy and through to adolescence, hematogenous osteomyelitis greatly predilects the long bones of the extremities.
What is hematogenous osteomyelitis in infants and children?

When does acute osteomyelitis become a chronic condition?
About 10 to 14 days after the onset of symptoms, x-rays show signs of the bone infection. Intravenous antibiotic treatment is usually effective. If not, the infection destroys areas of the bone and an abscess forms. Acute osteomyelitis may become chronic, especially if the patient has a low resistance to infection.
