摘要：

背景：目前截骨矫形术截骨面确定方法多基于二维X射线片及经验大致判断，精度较差。
目的：运用数字仿真技术精确确定桡骨截骨矫形术的截骨面。
方法：将1例桡骨畸形伴桡骨前倾角及桡骨内倾角异常患者的CT扫描数据集(双侧)依次导入Mimics进行三维重建，用计算机辅助作图及空间解析几何计算确定截骨面并测量相关参数，利用数字化仿真技术模拟手术截骨及复位。
结果与结论：原文的方法能确定并测量双侧桡骨截骨矫形术的截骨面，为手术提供精确而直观的指导。

Abstract:

BACKGROUND: At present, most of the methods to determine the cut planes of corrnective osteotomy are based on two-dimensional X-ray films and empirical judgment, and the accuracy is poor.
OBJECTIVE: To accurately determine the cut planes of the radial osteotomy by digital simulation technique.
METHODS: A CT scanning data of double carpal joint of a patient with multiple exostoses was imported into Mimics for three-dimensional reconstruction. The computer-aided design and spatial analytic geometry was used to determine the cut planes and measure their parameters, digital simulation technique was used to simulate the surgical procedure of osteotomy and reduction.
RESULTS AND CONCLUSION: The method mentioned in article can determine and measure the bilateral cut planes of the radial corrective osteotomy, providing an accuracy and intuitive clinical guide.
