What is acute hematogenous?

Acute hematogenous osteomyelitis is an infection that usually affects the growing skeleton, involving primarily the most vascularized regions of the bone. It is considered an acute process if the symptoms have lasted less than 2 weeks (2,3).

What are the three types of osteomyelitis?

Traditionally, osteomyelitis is a bone infection that has been classified into three categories: (1) a bone infection that has spread through the blood stream (Hematogenous osteomyelitis) (2) osteomyelitis caused by bacteria that gain access to bone directly from an adjacent focus of infection (seen with trauma or …

Which is the most common causes of hematogenous osteomyelitis?

[1] The most common pathogens in osteomyelitis depend on the patient’s age. Staphylococcus aureus is the most common cause of acute and chronic hematogenous osteomyelitis in adults and children. [1][5] Increasingly isolated from patients with osteomyelitis is methicillin-resistant Staphylococcus aureus (MRSA).

What is Haematogenous osteomyelitis?

Hematogenous osteomyelitis is clearly a systemic infection because bacteremia seeds proximal and distal long bones or paravertebral plexuses, resulting in acute bone infection and destruction.

How is hematogenous osteomyelitis diagnosed?

The preferred diagnostic criterion for osteomyelitis is a positive bacterial culture from bone biopsy in the setting of bone necrosis. Magnetic resonance imaging is as sensitive as and more specific than bone scintigraphy in the diagnosis of osteomyelitis.

What is the mortality rate for 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 is hematogenous spread of infection?

Bacteria can also spread via the blood to other parts of the body (which is called hematogenous spread), causing infections away from the original site of infection, such as endocarditis or osteomyelitis.

How common is hematogenous osteomyelitis?

Epidemiology. Acute hematogenous osteomyelitis (AHO) and septic arthritis are most common in the first decade of life. Approximately 40% of cases of septic arthritis occur in the knee,4–7 and approximately 30% of cases of AHO occur about the knee (distal femur, proximal tibia, proximal fibula).
