【摘要】：目的：初步探讨计算机软件对桡骨远端X线影像测量的准确性和可行性。 方法：选取中国中医科学院望京医院放射科拍摄的标准腕关节数字化X线片30张,实验者本人用计算机腕关节测量软件进行相关测量；从上述X线片中随机选取1张,并从中国中医科学院望京医院骨科研究生中随机选取30名,此30名人员分别利用临床量尺测量方法及计算机腕关节测量软件测量的方法对上述1张X线片测量,每人每种方法测量一次。测量主要内容：桡骨尺偏角、尺骨变异、桡腕关节弧的弦长。 结果：计算机腕关节测量软件对桡骨纵轴的确定：远端取斜率点到桡腕关节面的距离为38.996±10.494mm,近端中点到桡腕关节面的距离为69.337±11.011mm；计算机腕关节测量软件测量数值的标准差、极差、离散系数等均较量尺测量的数值小；取测量值的离均差绝对值进行统计检验分析：尺偏角及桡腕关节弦长的P值小于0.05,具有统计学意义；尺骨变异的P值大于0.05,不具有统计学意义。 结论：不同人利用计算机腕关节测量软件进行测量的数值离散度较小,该软件具有较好的一致性及可重复性。
[Abstract]:Objective: to explore the accuracy and feasibility of computer software for radiographic measurement of distal radius. Methods: a total of 30 digital radiographs of wrist joint were taken by the Department of Radiology of Wangjing Hospital of Chinese Academy of traditional Chinese Medicine. Thirty graduate students of orthopedics in Wangjing Hospital of Chinese Academy of traditional Chinese Medicine were randomly selected. The 30 subjects were measured by the methods of clinical measurement and computer software measurement of wrist joint. Each method is measured once per person. Main content: radial ulnar deviation, ulnar variation, radial wrist arc chord length. Results: the distance between distal slope point and radiocarpal joint surface was 38.996 卤10.494mm and 69.337 卤11.011mm between the midpoint of proximal end and radiocarpal joint surface, and the standard deviation and extreme deviation of the value measured by computer wrist joint measurement software were obtained by using computer wrist joint measurement software to determine the longitudinal axis of radius: the distance from the distal slope to the radiocarpal joint was 38.996 卤10.494mm and 69.337 卤11.011mm, respectively. The difference between the measured values and the mean value was analyzed statistically: the P value of the ulnar deviation angle and the chord length of the radiocarpal joint was less than 0.05, which had statistical significance. The P value of ulnar variation was more than 0.05, which had no statistical significance. Conclusion: the numerical dispersion of wrist joint measurement software is small, and the software has good consistency and repeatability.
