Ultrasound of Acute Hematogenous Osteomyelitis in Young Children in Accordance with the Terms of the Disease

67 children with suspected acute hematogenous osteomyelitis were examined. Acute hematogenous osteomyelitis was diagnosed after the surgery in 52 (77.6%) cases and septic arthritis in 10 (14.9%). Inflammatory changes were not revealed in 5 (7.5%) cases. All patients were divided into three groups in accordance with their admission to the hospital. The first group included children admitted in the first week of onset (n = 31; 46.3%). Subgroup 1A - children admitted in the first 3 days of onset (n = 16; 23.9%), subgroup 1B - children admitted at 4-7 days of onset (n = 15; 22.4%). Children admitted at 8-14 days formed the second group (n = 24; 35.8%), at 15-21 days - third group (n = 12; 17.9%). Metaepiphyseal zone changes were the main ultrasound signs of the acute hematogenous metaepiphyseal osteomyelitis. They were more distinct at the end of the first week (4-7 days). Ultrasound signs of the acute hematogenous metaepiphyseal osteomyelitis at period 1-3 days were unspecific, and their identification required further follow-up. Synovial fluid presence could be the symptom of the arthritis and osteomyelitis as well. Sensitivity of the ultrasound in acute hematogenous metaepiphyseal osteomyelitis diagnosis during the first three days of the disease was 85.7%, specificity - 88.9%, accuracy - 87.5%; 4-7 days - 100.0, 80.0, and 93.3%, respectively. Sensitivity of the ultrasound at period 8-21 days was 100.0%.
