Three children aged 13 to 15 months had been pulled by the wrist. Subsequent pain and limitation of motion were typical of nursemaid's elbow. On radiographs, a line drawn through the longitudinal axis of the radius failed to bisect the humeral capitellum as is normally seen. Both the symptoms and the radiographic abnormalities resolved after successful manipulative reduction.
三名13至15个月大的儿童被牵拉手腕。随后出现的疼痛和活动受限是桡骨头半脱位的典型症状。在X线片上，一条沿桡骨纵轴画的线未能像正常情况下那样将肱骨小头平分。手法复位成功后，症状和影像学异常均消失。
