The diagnosis of traumatic dislocation of the radial head, either isolated or as part of a Monteggia fracture-dislocation, was delayed in 10 of the 110 children treated with these injuries during the study period. In eight children, the dislocation was overlooked on the initial radiographs. In two children, the radial head was reduced on the initial elbow radiographs, but it was dislocated 10 days later in one child and 21 days later in the other. The most likely explanation is that the radial head dislocated at the time of impact, spontaneously reduced by the time the first radiographs were obtained, and redislocated while the arm was in a cast. We conclude that radiographic assessments of the radiocapitellar joint, by using the radiocapitellar line, are required in children with elbow and forearm injuries at presentation and when the cast is removed.
在研究期间接受这些损伤治疗的110名儿童中，有10名儿童的桡骨头创伤性脱位（无论是孤立性的还是孟氏骨折脱位的一部分）诊断被延迟。在8名儿童中，初次X线片上脱位被漏诊。在2名儿童中，初次肘部X线片显示桡骨头已复位，但其中1名儿童在10天后再次脱位，另1名儿童在21天后再次脱位。最可能的解释是，桡骨头在撞击时脱位，在获得第一张X线片时自发复位，并在手臂石膏固定期间再次脱位。我们得出结论，对于肘部和前臂受伤的儿童，就诊时以及拆除石膏时，需要使用桡骨头线对桡肱关节进行X线评估。
