We describe a case of external snapping hip diagnosed by dynamic sonography. The case prompted us to retrospectively review the imaging findings of children who clinically had presented with snapping hip. From this review we identified the features on MRI and CT of either thickening of the iliotibial band or thickening of the anterior edge of the gluteus maximus muscle as the cause of snapping and atrophy of the bulk of gluteus maximus muscle as an important secondary sign associated with snapping.
我们描述了一例通过动态超声诊断的臀肌外弹响髋病例。该病例促使我们回顾性分析临床上表现为弹响髋的儿童的影像学表现。通过此次回顾，我们确定了磁共振成像（MRI）和计算机断层扫描（CT）上显示的阔筋膜张肌增厚或臀大肌前缘增厚是弹响的原因，而臀大肌大部分萎缩是与弹响相关的一个重要次要征象。
