Osteomyelitis on plain radiographs:
- Early signs：adjacent soft tissues swelling, with or without displacement or obscuration of the soft tissue plane
- Osseous changes become apparent 10 to 14 days after infection and may include decreased bone mineralization, periosteal reaction, focal resorption of the inner cortical layer, lytic lesions, or new bone formation
- Subacute: Brodie abscess (most commonly at metaphysis of tibia), is an oval-shaped area of decreased density
- Chronic: thickened and irregular bone with sclerosis and a nonaggressive periosteal reaction, sequestrum, cloaca
