Corrective osteotomy for distal radial malunion is a valuable but at times technically challenging operation. We have developed a new device to aid in the performance of the operation. We compared clinical use of the new technique with the standard technique. In 11 patients treated with the new technique the volar locking plate needed repositioning only once. With the standard technique in 17 patients the plate was repositioned in nine cases and needed bending in six cases. The new method corrected radial inclination (SD of 3° vs. 9°) and ulnar variance (SD of 0.9 mm vs. 1.4 mm) more predictably than the standard technique but there was no advantage in correction of volar tilt (SD of 6° vs. 4°). In our experience the new device makes corrective osteotomy of the distal radius easier and more reliable.
桡骨远端畸形愈合的矫正截骨术是一项有价值但有时在技术上具有挑战性的手术。我们开发了一种新装置来辅助该手术的实施。我们将新技术的临床应用与标准技术进行了比较。在11例采用新技术治疗的患者中，掌侧锁定钢板仅需重新定位1次。采用标准技术治疗的17例患者中，钢板在9例中需要重新定位，6例需要弯曲。与标准技术相比，新方法在矫正桡骨倾斜度（标准差分别为3°和9°）和尺骨变异（标准差分别为0.9 mm和1.4 mm）方面更具可预测性，但在矫正掌侧倾斜度方面没有优势（标准差分别为6°和4°）。根据我们的经验，新装置使桡骨远端的矫正截骨术更容易且更可靠。
