超声对早期急性骨髓炎的诊断价值

The value of sonography in the diagnosis of early acute osteomyelitis

为了探讨超声对早期急性骨髓炎的诊断价值，我们对15例临床疑有早期急性骨髓炎，首次X线检查骨骼无异常发现的患者作了超声检查。15例中有6例显示骨膜下脓肿，表现为骨膜掀起及骨膜与骨皮质之间的暗区。这6例经手术和／或骨膜下穿刺以及随诊证实为早期急性骨髓炎。另9例经证实的软组织感染未见骨膜下脓肿。结果表明，超声对X线无骨路异常表现的早期急性骨髓炎可作出诊断，并可与软组织感染鉴别。

In order to evaluate the value of sonography in the diagnosis of early os-teomyelitis, 15 patients suspected to have early acute osteomyelitis with initial nor-mal bone radiograph were examined by ultrasound. Subperiosteal abscess, mani-fested as periosteal elevation and anechoic area between the periosteum and the bone cortex were detected in 6 of the 15 patients. These 6 patients were proved to have acute osteomyelitie by follow-up, surgery and / or subperiosleal needle aspi-ration. No subperiosteal abscess was detected in the remaining 9 patients who had proven soft-tissue infection. It is shown that early acute osteomyelitis without any abnormal roentgenographic bone findings can be diagnosed and differentiated from soft-tissue infection by sonography.
