The purpose of this study was to investigate the use of elbow arthrography for detecting an occult subluxation of the radial head and for verifying the quality of reduction in children with ulnar fractures. The study involved 15 children who underwent closed reduction (with or without percutaneous pinning) based on arthrography for minimally displaced fractures with or without radial head subluxation. The mean age of the patient at the time of surgery was 6 years (range, 3-12 years). Initial diagnoses based on conventional radiographs were compared with arthrographically confirmed final diagnoses in groups of children with ulnar fractures of the olecranon, proximal, and diaphysis. Arthrography confirmed initial radiographic diagnoses in 10 and altered diagnoses in five patients. We conclude that arthrography can be useful for detecting an occult subluxation of the radial head and for evaluating adequate reduction in children of less than 6 years with ulnar fractures.
本研究的目的是探讨肘关节造影在检测儿童桡骨头隐匿性半脱位以及验证尺骨骨折复位质量方面的应用。该研究纳入了15例儿童，这些儿童因伴有或不伴有桡骨头半脱位的轻度移位骨折，基于肘关节造影接受了闭合复位（有或无经皮穿针固定）。手术时患者的平均年龄为6岁（范围3 - 12岁）。将基于传统X线片的初步诊断与肘关节造影确诊的最终诊断在鹰嘴、近端和骨干尺骨骨折儿童组中进行比较。肘关节造影证实了10例患者的初步X线诊断，改变了5例患者的诊断。我们得出结论，肘关节造影可用于检测桡骨头隐匿性半脱位，并评估6岁以下尺骨骨折儿童的充分复位情况。
