The purpose of this study was to describe the results of a newly developed method of correction osteotomy for congenital radioulnar synostosis. With this method the osteotomy is performed at the distal one third of the radius and proximal one third of the ulna. After K-wires are inserted intramedullarly into both bones the forearm is derotated manually to the position planned before surgery followed by cast immobilization.
Four patients with an average age of 3.9 years underwent surgery with this method and were followed-up for 45.8 months. All of their forearms were fixed before surgery at over 70 degrees of pronation.
The average correction after surgery was 65 degrees and bone union occurred at 8 weeks after surgery without any complications. The patients' ability to perform daily activities showed a marked improvement after surgery, but there was a 20 degrees loss of correction during cast immobilization in one case.
This method is a simple and safe technique to derotate the forearms of the patients with congenital radioulnar synostosis that are fixed in pronation.
本研究旨在描述一种新开发的用于先天性桡尺骨融合矫正截骨术的结果。采用该方法时，截骨术在桡骨远端三分之一和尺骨近端三分之一处进行。在将克氏针经皮插入两根骨头后，手动将前臂旋转至术前计划的位置，随后进行石膏固定。
4例平均年龄3.9岁的患者采用该方法接受手术，并随访45.8个月。术前他们所有的前臂均固定在旋前超过70度的位置。
术后平均矫正角度为65度，术后8周骨愈合，无任何并发症。患者的日常活动能力术后有显著改善，但1例在石膏固定期间矫正角度丢失了20度。
该方法是一种简单安全的技术，可用于矫正固定于旋前位的先天性桡尺骨融合患者的前臂。
