This case report documents a rare cause of block to reduction in association with an anterior traumatic dislocation of the radial head in children. The radial head dislocations described were not reducible with a closed reduction secondary to "button holing" of the radial head through the anterior joint capsule. Open reduction was required to release the capsule and reduce the radial head. After reduction, the elbow was immobilized in flexion and the forearm in mild supination for 3 weeks. Postoperatively, all patients demonstrated full elbow function and range of function.
本病例报告记录了一种罕见的导致儿童桡骨头前外伤性脱位复位失败的原因。描述的桡骨头脱位由于桡骨头通过前关节囊“纽扣孔”而无法通过闭合复位进行复位。需要进行开放性复位以松解关节囊并复位桡骨头。复位后，肘部保持屈曲位，前臂轻度旋前位固定 3 周。术后，所有患者均表现出完全的肘部功能和活动范围。
