Abstract

A 3-year old boy with an acute onset of hip pain and limitation of motion had 4 mm of crescent shaped intra-articular gas produced by manual traction radiography. Hip aspiration produced more than 2 ml of fluid from the hip. Manual traction radiography producing the vacuum phenomenon with release of crescent shaped intra-articular gas did not exclude joint fluid in this patient.

摘要

一名3岁男孩急性起病，出现髋部疼痛和活动受限，手法牵引X线摄影显示关节内有4毫米新月形气体。髋关节穿刺抽出超过2毫升的髋关节积液。手法牵引X线摄影产生真空现象并释放出新月形关节内气体，但这并未排除该患者存在关节积液。
