超声对儿童肱骨远端Ⅰ型骨骺损伤的诊断价值

摘要

目的:探讨超声对儿童肱骨远端Ⅰ型骨骺损伤的诊断价值.方法:回顾性分析8例婴幼儿肱骨远端骨骺损伤的病例资料,并将超声检查结果与X线、CT及手术所见进行对比分析.结果:8例患儿经X线及CT检查,均未见明显骨折线,均报告为肘关节脱位不能排除,超声检查准确诊断为肱骨远端Ⅰ型骨骺损伤,并完全排除肘关节脱位,避免了误诊.远端骨骺向肱骨背侧滑移的“阶梯”征象及“尺骨鹰嘴消失征”为其特异性超声表现.结论:超声检查是诊断儿童肱骨远端Ⅰ型骨骺损伤的有效方法,具有较高的临床应用价值.%Objective=The purpose of this study is to improve the ultrasound diagnostic accuracy of type Ⅰ epiphyseal injuries of distal humerus in children.Methods:Eight children with the type Ⅰ epiphyseal injuries of distal humerus were collected.Their diagnostic results by ultrasound imaging were analyzed and compared with X-ray,CT scan and operation results.Results:Except for suspicious epiphyseal separation,there was no obvious fracture sign on X-ray and CT images in all 8 children with type Ⅰ epiphyseal injuries of distal humerus.However,they were diagnosed as epiphyseal injuries instead of dislocation by ultrasound.The ultrasound diagnoses were consistent to operation results."Staircase sign",dorsal displacement of distal epiphysis,and "olecranon vanishing sign" are specific diagnostic signs on ultrasound.Conclusion=Ultrasound examination is an effective and valuable method in diagnosis of type Ⅰ distal humeral epiphyseal injuries in young children.
