Acute osteomyelitis

Acute osteomyelitis is a rapid-onset, severe infection of cortical bone and the medullary cavity, most frequently caused by pyogenic bacteria such as *Staphylococcus aureus*

Acute osteomyelitis is a rapid-onset, severe infection of cortical bone and the medullary cavity, most frequently caused by pyogenic bacteria such as *Staphylococcus aureus* Pathophysiologically, microbial invasion induces acute inflammation, purulence, and increased intramedullary pressure, which can impair local vascular perfusion and precipitate ischemic necrosis, cortical destruction, or subperiosteal abscess formation

Acute osteomyelitis is a rapid-onset, severe infection of cortical bone and the medullary cavity, most frequently caused by pyogenic bacteria such as *Staphylococcus aureus* It affects the skeletal system across all demographics, manifesting predominantly as hematogenous seeding in the metaphyseal regions of long bones in children, and more commonly arising from contiguous soft-tissue extension, trauma, or direct surgical inoculation in adults Patients typically present within days to two weeks ...

It affects the skeletal system across all demographics, manifesting predominantly as hematogenous seeding in the metaphyseal regions of long bones in children, and more commonly arising from contiguous soft-tissue extension, trauma, or direct surgical inoculation in adults

Pathophysiologically, microbial invasion induces acute inflammation, purulence, and increased intramedullary pressure, which can impair local vascular perfusion and precipitate ischemic necrosis, cortical destruction, or subperiosteal abscess formation

Patients typically present within days to two weeks with localized bone pain, erythema, warmth, and swelling, frequently accompanied by fever, impaired mobility, and elevated systemic inflammatory markers
