Osteomyelitis is most common in young kids under age 5. But it can happen at any age. Boys get it almost twice as often as girls do.
Smokers and people with chronic health conditions, such as diabetes or kidney failure, are more at risk of developing osteomyelitis. People who have diabetes may develop osteomyelitis in their feet if they have foot ulcers.
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.
Osteomyelitis is more common in younger children (five and under) but can happen at any age. Boys are usually more affected than girls. Antibiotics are often prescribed to treat osteomyelitis. Surgery may also be recommended in certain cases.
How common is osteomyelitis? Osteomyelitis affects about 2 to 5 out of every 10,000 people. It's one of the oldest diseases on record. Scientists have traced it back more than 250 million years.
Overview. Incidence of osteomyelitis is approximately 13 per 100,000 in children and approximately 90 per 100,000 in adults. Hematogenous osteomyelitis occurs predominantly in children and elderly patients while osteomyelitis due to contiguous infection is most common in adults.
In children, an infection in the blood is a common cause of osteomyelitis. This is because a child's growing bones have an increased blood supply. That makes it easier for the bacteria to get into the bone. An infection from nearby soft tissue or from a wound may also lead to osteomyelitis.
Bone infection is most often caused by bacteria. But it can also be caused by fungi or other germs. When a person has osteomyelitis: Bacteria or other germs may spread to a bone from infected skin, muscles, or tendons next to the bone.
It characterizes osteomyelitis as being in one of four anatomic stages. In stage 1, or medullary, osteomyelitis is confined to the medullary cavity of the bone. Stage 2, or superficial, osteomyelitis involves only the cortical bone and most often originates from a direct inoculation or a contiguous focus infection.
Osteomyelitis is a painful bone infection. It usually goes away if treated early with antibiotics. If not, it can cause permanent damage.
Acute osteomyelitis is usually acquired hematogenously, and the most common pathogen is Staphylococcus aureus. Acute osteomyelitis can usually be cured with antimicrobial therapy alone. In contrast, chronic osteomyelitis may be caused by S. aureus but is often due to gram-negative organisms.
Acute osteomyelitis develops rapidly over a period of seven to 10 days. The symptoms for acute and chronic osteomyelitis are very similar and include: Fever, irritability, fatigue.
Open upper extremity fractures with severe soft-tissue damage have the highest risk of developing osteomyelitis.
The duration of follow-up for patients with nonfatal cases ranged from 2 days to 38 years (median, 6.5 years). The outcome of 255 episodes was recovery in 146 (57%), qualified recovery in 80 (31%), and death in 29 (11%). The 1-year cumulative mortality rate was 11.3% ± 2.0% (95% CI, 7.4–15.2).
Osteomyelitis is more likely to occur in people with compromised immune systems. Patients with sickle cell disease or HIV or those taking immunosuppressive agents like chemotherapy or steroids are at higher risk. Depending on the cause of the infection, osteomyelitis may be acute or chronic.
One way to prevent osteomyelitis is to keep skin clean. All cuts and wounds — especially deep wounds — should be cleaned well. Wash a wound with soap and water, holding it under running water for at least 5 minutes to flush it out. To keep the wound clean afterward, cover it with sterile gauze or a clean cloth.
Acute - Acute osteomyelitis occurs suddenly and will show in diagnostic tests or procedures about two weeks after infection. This type of osteomyelitis is usually easier to treat. However, if left untreated, it can progress into chronic osteomyelitis.
Histology is necessary to ensure diagnosis. Late onset osteomyelitis could occur up to 30 years after an initial complex fracture as an outburst of chronic silent osteomyelitis.
Reiter's syndrome, on the other hand, is a form of arthritis that is triggered by an infection in another part of the body. It also presents with joint pain, swelling, redness, and similar symptoms with osteomyelitis.
A blood test or imaging test such as an x-ray can tell if you have a bone infection.
Osteomyelitis is a serious condition requiring immediate medical attention. It's more common in premature infants and babies born with complications. The treatment for osteomyelitis usually involves antibiotics. In rare and severe cases, a bone may need to be amputated.
Acute osteomyelitis is the clinical term for a new infection in bone. This infection occurs predominantly in children and is often seeded hematogenously. In adults, osteomyelitis is usually a subacute or chronic infection that develops secondary to an open injury to bone and surrounding soft tissue.
Male sex, advanced age, and diabetes were also associated with an increased risk of osteomyelitis following fracture [13]. These findings are largely rooted in studies investigating military populations.
Microbiology. Blood cultures should always be obtained when osteomyelitis is suspected, though they are often negative except in cases of hematogenous osteomyelitis. The gold standard for the diagnosis of osteomyelitis is bone biopsy with histopathologic examination and tissue culture.
