Abstract:
:The authors correlated sonographic findings with histologic findings in a rabbit model of osteomyelitis. Staphylococcus aureus osteomyelitis was induced in the femora of 11 New Zealand white rabbits. The opposite leg was used as a control. Sonographic findings showed fluid adjacent to the bone in 11 cases. The fluid was believed to be an inflammatory exudate, and its presence suggested osteomyelitis. Pathologic analysis showed extraperiosteal purulent fluid adjacent to the cortex as well as histopathologic changes of osteomyelitis in the 11 rabbits. There was one false-positive sonographic diagnosis of osteomyelitis in a rabbit that had a soft tissue abscess adjacent to the cortex.
