Acute annular ligament interposition into the radiocapitellar joint ("nursemaid's elbow") is a common injury in children younger than 5 years. The injury occurs when axial traction is applied to an extended, pronated arm. There are no abnormal radiographic findings associated with this condition. We recommend that children with a classic history and clinical presentation of an acute annular ligament interposition into the radiocapitellar joint be treated without obtaining radiographs.
急性环状韧带嵌入桡骨头关节（“保姆肘”）是5岁以下儿童的常见损伤。当对伸直、旋前的手臂施加轴向牵引力时就会发生这种损伤。这种情况没有相关的异常影像学表现。我们建议，对于有急性环状韧带嵌入桡骨头关节典型病史和临床表现的儿童，无需进行X光检查即可进行治疗。
