To describe the ultrasound (US) features of reactivation in post-traumatic chronic osteomyelitis in adults.
Twelve patients with clinical suspicion of reactivation of chronic osteomyelitis, secondary to trauma, surgery, and who were investigated with US were selected for the study. The following US features were assessed: periosseous fluid collection, bone changes (periosteal reactions, cortical irregularity, callus, sequestrum and cloaca) and soft-tissue changes (cellulitis and sinus tracts). US findings were correlated with plain radiography (n = 11), computed tomography (n = 3) and magnetic resonance imaging (n = 2).
US detected fluid collections in all patients (12 periosseous and 3 in soft tissues), bone changes in 10 and sinus tracts and cellulitis in 5 patients each. Bone changes detected were cortical irregularity (n = 10), discontinuity of cortex (n = 7), sequestrum (n = 2), callus (n = 2), periosteal reaction (n = 1) and cloaca (n = 1). Cellulitis was seen in 5 patients and sinus tracts in 5. Reactivation was confirmed at surgery in all patients.
US is a reliable noninvasive imaging modality for the diagnosis of reactivation of post-traumatic chronic osteomyelitis in adults.
描述成人创伤后慢性骨髓炎再激活的超声（US）特征。
选取12例临床怀疑慢性骨髓炎再激活（继发于创伤、手术）且接受超声检查的患者进行研究。评估以下超声特征：骨膜下积液、骨质改变（骨膜反应、皮质不规则、骨痂、死骨和骨空洞）以及软组织改变（蜂窝织炎和窦道）。超声检查结果与X线平片（n = 11）、计算机断层扫描（n = 3）和磁共振成像（n = 2）结果进行对比。
超声检查发现所有患者均存在积液（12例骨膜下积液和3例软组织积液），10例存在骨质改变，5例存在窦道和蜂窝织炎。检测到的骨质改变包括皮质不规则（n = 10）、皮质连续性中断（n = 7）、死骨（n = 2）、骨痂（n = 2）、骨膜反应（n = 1）和骨空洞（n = 1）。5例患者出现蜂窝织炎，5例出现窦道。所有患者手术时均证实存在再激活。
超声是诊断成人创伤后慢性骨髓炎再激活的一种可靠的非侵入性成像方法。
