目前,铜缺乏已确认为一临床病种。多数儿科医生尚无简便方法衡定血浆的铜含量。而且血铜正常值变化较大,因此用骨骼X线照片识别本病尤其重要。关于铜缺乏的X线表现现仍有争议。本文目的系列出铜缺乏的所见并讨论鉴别诊断。X线表现:铜缺乏的早期主要表现为干骺端和骨骺骨质稀疏。此期,放射诊断无特异性。骨龄延迟。随病情的发展,临时钙化带大体完好,只呈现轻度不规则和杯形。此后,干骺端可见到镰状骨刺。正和其他营养缺乏病一样尺骨远端病理改变比桡骨远端更 Currently, copper deficiency has been identified as a clinical disease. There is no easy way for most pediatricians to determine plasma copper levels. And blood copper normal changes, so the use of bone X-ray photo identification of the disease is particularly important. X-ray performance on the lack of copper is still controversial. The purpose of this article is to outline the findings of copper deficiency and to discuss differential diagnosis. X-ray findings: The early manifestations of copper deficiency mainly for the metaphysis and epiphyseal bone sparse. This period, radiological diagnosis of non-specific. Bone age is delayed. With the development of the disease, temporary calcification zone generally intact, showing only mild irregular and cup-shaped. Since then, sickle bone spurs can be seen on the metaphysis. As with other nutritional deficiencies, distal ulnar pathology is more distal than the distal radius
