What is osteomyelitis?
Osteomyelitis is a bacterial, or fungal, infection of the bone. Osteomyelitis affects about 2 out of every 10,000 people.
What is the most common form of hematogenous osteomyelitis?
Although rare, NVO is the most common form of hematogenous osteomyelitis in patients aged >50 years and represents 3%–5% of all cases of osteomyelitis . An increase in the incidence of NVO has been attributed to an increase in susceptible patients such as intravenous drug users, individuals undergoing hemodialysis, and immunocompromised hosts.
What is osteomyelitis menu?
Osteomyelitis Menu. 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.
What happens if you get osteomyelitis from illegal drugs?
People who inject illegal drugs are more likely to develop osteomyelitis because they may use nonsterile needles and are less likely to sterilize their skin before injections. Osteomyelitis complications may include: Bone death (osteonecrosis). An infection in your bone can impede blood circulation within the bone, leading to bone death.
What is the pathophysiology of hematogenous osteomyelitis?
In adults with hematogenous osteomyelitis, Staphylococcus aureus is the most common organism isolated. Pseudomonas osteomyelitis is seen in drug addicts and has predilection for spine ( Table 1 ). Clinical features include chills, fever, malaise, pain and local swelling of the affected limb.
How does osteomyelitis affect children?
In children, osteomyelitis usually affects the adjacent ends of long bones. Long bones (bones in the arms or legs) are large, dense bones that provide strength, structure and mobility.
What are the diagnostic criteria for osteomyelitis (OM)?
Histopathologic examination of bone specimens coupled with bone culture is considered the gold standard for the diagnosis of osteomyelitis (OM). Despite this, studies have demonstrated interpathologist agreement in the diagnosis of OM as low as 30%, largely stemming from a lack of specific definitions and diagnostic criteria.
How common is interpathologist agreement in the diagnosis of osteomyelitis?

Osteomyelitis – StatPearls – NCBI Bookshelf Bone infection is called osteomyelitis. It is an acute or chronic inflammatory process involving the bone and its structures secondary to infection with pyogenic organisms, including bacteria, fungi, and mycobacteria.
How do Lew Lew and Waldvogel classify osteomyelitis?
Lew and Waldvogel classified osteomyelitis based on the duration of illness as acute or chronic and by the mechanism of infection (either hematogenous or contiguous infection). Contiguous infection is further classified based on the presence or absence of associated vascular insufficiency.
What are the risk factors for osteomyelitis?
Risk factors. Your bones are normally resistant to infection, but this protection lessens as you get older. Other factors that can make your bones more vulnerable to osteomyelitis may include: A severe bone fracture or a deep puncture wound gives bacteria a route to enter your bone or nearby tissue.
