Despite several techniques for corrective osteotomy in congenital radioulnar synostosis (CRUS) the published literature lacks a guide for radiographic planning and rationale for the site and level of the osteotomy. The primary objective of this study is to report a technique of radiographically controlled corrective osteotomy using the axis of rotation of the forearm in CRUS.
Children with CRUS underwent corrective osteotomy based on radiographic planning; the extent of rotational correction and functional outcomes were assessed at a mean of 27 months after the operation.
Seven forearms in six children of an average of 6.25 years were assessed for correction and functional outcomes. The average pre-operative pronation deformity was 71.5°. The average correction achieved was 64°. At follow-up, there were five excellent and two good functional outcomes. All children could perform daily tasks besides eating with hand and personal hygiene.
Radiographic determination of the osteotomy sites by the method described is effective, consistent, and reproducible in achieving optimal functional outcomes in congenital radioulnar synostosis.
尽管先天性桡尺骨融合（CRUS）有多种矫正截骨技术，但已发表的文献缺乏影像学规划指南以及截骨部位和水平的理论依据。本研究的主要目的是报告一种在CRUS中使用前臂旋转轴进行影像学控制的矫正截骨技术。
患有CRUS的儿童根据影像学规划接受矫正截骨术；术后平均27个月评估旋转矫正程度和功能结果。
对6名平均年龄6.25岁儿童的7条前臂进行了矫正和功能结果评估。术前平均旋前畸形为71.5°。平均矫正角度为64°。随访时，功能结果为5例优秀，2例良好。除了用手吃饭和个人卫生外，所有儿童都能完成日常任务。
通过所述方法进行影像学确定截骨部位，在实现先天性桡尺骨融合的最佳功能结果方面是有效、一致且可重复的。
