A nursemaid's elbow most frequently occurs with transient longitudinal traction of the pronated forearm and extended elbow, which can be reduced by manipulation without sedation. There are circumstances in which the history is atypical and reduction of the elbow is unsuccessful. Imaging may be helpful in these cases.
A 33-month-old child was injured in a fall from a tire swing and sustained what was thought to be a nursemaid's elbow. Typical reduction maneuvers were unsuccessful. The patient underwent magnetic resonance imaging (MRI) with conscious sedation, which demonstrated the entrapment of the annular ligament in the radicapitellar joint. A presumed successful reduction was performed with confirmed reduction of the annular ligament by immediate MRI.
To our knowledge, this is the first case report on MRI being used to diagnose and confirm treatment of an atypical nursemaid's elbow.

桡骨头半脱位最常发生于旋前位前臂和伸直位肘关节的短暂纵向牵拉，可通过非镇静手法复位。在某些情况下，病史不典型且肘关节复位不成功。影像学检查在这些病例中可能会有所帮助。
一名33个月大的儿童从轮胎秋千上跌落受伤，被诊断为桡骨头半脱位。典型的复位手法未成功。患者在清醒镇静下接受了磁共振成像（MRI）检查，结果显示环状韧带嵌顿于桡骨头关节。通过立即进行的MRI确认环状韧带已复位，随后进行了一次假定成功的复位。
据我们所知，这是首例关于使用MRI诊断和确认非典型桡骨头半脱位治疗情况的病例报告。
