This study compares in normal subjects the variability of wrist x-ray film measurements between the right and left sides with the variability of the distribution of those measurements within the population. Additional purposes were to evaluate possible differences of these measurements according to sex, age, side, and hand dominance. The variability when comparing both sides was found to be statistically less for the carpal height, radiolunate, scapholunate, and capitolunate angles than within the whole group of subjects, and for those measurements, there was a high correlation (r > .88) between the right and left sides. In addition, the carpal height and the carporadial ratios were lower and the capitolunate angle was higher in women than in men. There was also a significant decrease of the scapholunate angle in older individuals. The clinical implication of these findings is that in unilateral wrist diseases, the normal wrist should be used to provide the reference values of the carpal height and of the carpal angles on profile x-ray films. However, for the radial inclination and palmar tilt of the distal radius and for the ulnar variance, the normal side does not provide a better reference than normal values obtained from databases.
本研究在正常受试者中比较了左右两侧腕部X线片测量值的变异性与这些测量值在人群中的分布变异性。其他目的是根据性别、年龄、侧别和利手评估这些测量值可能存在的差异。结果发现，在比较两侧时，腕高、桡月角、舟月角和头月角的变异性在统计学上低于整个受试者组内的变异性，并且对于这些测量值，左右两侧之间存在高度相关性（r>.88）。此外，女性的腕高和腕桡比低于男性，而头月角高于男性。老年个体的舟月角也有显著减小。这些发现的临床意义在于，在单侧腕部疾病中，应使用正常腕部来提供侧位X线片上腕高和腕角的参考值。然而，对于桡骨远端的桡侧倾斜和掌侧倾斜以及尺骨变异，正常侧并不比从数据库获得的正常值提供更好的参考。
