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.

摘要

作者在兔骨髓炎模型中，将超声检查结果与组织学检查结果进行了对比。在11只新西兰白兔的股骨中诱发了金黄色葡萄球菌骨髓炎。对侧腿用作对照。超声检查结果显示，11例中骨旁有液体。该液体被认为是炎性渗出物，其存在提示骨髓炎。病理分析显示，11只兔子的皮质旁有骨膜下脓性液体以及骨髓炎的组织病理学变化。有1只兔子皮质旁有软组织脓肿，超声诊断骨髓炎出现了1例假阳性。
