The normal and abnormal anatomy of the hip joint in childhood was evaluated by ultrasonography (US) with reference to examination technique and errors. When compared with computed tomography (CT), it was confirmed that the two sonographic echoes from the hip joint represent the femoral neck and the external surface of the capsule and that the thickness of the echo received from the capsule depends on the frequency of the transducer. Partial volume effects may simulate or increase the sonographic appearance of hip joint effusion. The normal relationship between joint capsule and femoral neck was established.
通过超声检查（US），参考检查技术和误差，评估儿童髋关节的正常与异常解剖结构。与计算机断层扫描（CT）相比，已证实髋关节的两个超声回声分别代表股骨颈和关节囊的外表面，并且从关节囊接收到的回声厚度取决于换能器的频率。部分容积效应可能会模拟或增加髋关节积液的超声表现。建立了关节囊与股骨颈之间的正常关系。
