We report a unique case of posterior elbow dislocation with proximal radioulnar translocation in a six-year-old child with 3D reconstruction CT images. Five other cases of this type of association have been reported in the literature. Diagnosis is often established late. Our case illustrates the diagnostic and therapeutic difficulties. The CT scan demonstrated the presence of the proximal radioulnar translocation and contributed greatly to understanding the pathogenic mechanism: the radius crossed over the ulna anteriorly. The CT-scan can reveal associated lesions missed on the plain x-rays. Surgical reduction is generally needed, preferably via a medial approach.
我们报告了一例6岁儿童后肘部脱位合并近端桡尺关节移位的独特病例，并提供了三维重建CT图像。文献中还报道了其他5例此类关联病例。诊断通常较晚确立。我们的病例说明了诊断和治疗上的困难。CT扫描显示了近端桡尺关节移位的存在，并极大地有助于理解发病机制：桡骨向前越过尺骨。CT扫描可以发现平片上遗漏的相关损伤。通常需要手术复位，最好通过内侧入路。
