Analysis of radiographs of 52 wrists showed that, from ulnar to radial deviation, the amount of scaphoid shortening and ulnar translation of the scaphoid varies in a normal distribution. There is a significant correlation between the two measurements, such that the more the scaphoid shortens the less it translates and vice versa. Females subjects were more likely to have greater scaphoid shortening and less translation. It is felt that carpal kinematics thus cover a spectrum from the "row" theory to the "column" theory which is normally distributed and that women are more likely to have a column type wrist. This variation may affect the result of treatment of scapholunate dissociation by techniques such as scapho-lunate fusion. A "CR index" is proposed so that the tendency of a wrist towards row or column theory can be quantified. This may be used to predict the success of some surgical procedures in the treatment of scapho-lunate dissociation.
对52例腕关节X线片的分析表明，从尺偏到桡偏，舟骨缩短的程度和舟骨的尺侧移位呈正态分布变化。这两项测量之间存在显著相关性，即舟骨缩短越多，移位越少，反之亦然。女性受试者更有可能出现舟骨明显缩短和移位较少的情况。认为腕关节运动学涵盖了从“排”理论到“柱”理论的范围，呈正态分布，且女性更有可能具有柱型腕关节。这种变化可能会影响诸如舟月融合等技术治疗舟月分离的效果。提出了一个“CR指数”，以便能够量化腕关节向排或柱理论发展的趋势。这可用于预测一些治疗舟月分离手术的成功率。
