The aim of this study was to identify anatomic risk factors for scapholunate dissociation. On a PA view of the wrist, in zero position, the scaphoid and lunate diameter and height, lunate tilting angle, lunate uncovering index, lunate fossa inclination, radial inclination and ulnar variance were measured; on a lateral view the scapholunate angle and palmar tilting angle were measured. In a control group (N = 126) first left to right were compared which showed low correlations for radial inclination (r = 0.26), palmar tilt (r = 0.60) and ulnar variance (r = 0.68). These parameters were then measured on the affected hand in the study group, since they are not influenced by the dissociation, and no arthritic changes were seen. A statistically significant difference was found for a low lunate fossa inclination (p = 0.0001) and a low radial inclination (p = 0.0002). These factors may predispose to scapholunate dissociation.
本研究的目的是确定舟月骨分离的解剖学危险因素。在腕关节的正位片上，于零位时测量舟骨和月骨的直径和高度、月骨倾斜角、月骨覆盖指数、月骨窝倾斜度、桡骨倾斜度和尺骨变异；在侧位片上测量舟月角和掌侧倾斜角。在对照组（N = 126）中，首先比较了左侧和右侧，结果显示桡骨倾斜度（r = 0.26）、掌侧倾斜（r = 0.60）和尺骨变异（r = 0.68）的相关性较低。然后在研究组的患侧手上测量这些参数，因为它们不受分离的影响，且未观察到关节炎变化。发现月骨窝倾斜度低（p = 0.0001）和桡骨倾斜度低（p = 0.0002）存在统计学显著差异。这些因素可能易导致舟月骨分离。
