Acute Hematogenous Osteomyelitis
Key Points
Key Points
- Acute hematogenous osteomyelitis (AHO) occurs when bacteria enter and proliferate within the cellular and extracellular matrix of bone, generally accompanied by a host inflammatory response.
- The incidence of AHO in children ranges from 1.2 to 13 cases per 100,000 children per year
- Most of the cases involve a single bone, but about 5% involve multiple bones.
- The presentation of AHO varies from well-localized infection over a single metaphysis with a minimal associated systemic inflammatory response to multifocal infection with septic shock.
- Fever and pain are the most common manifestations of bone infection.
