Long-standing scapholunate instability frequently leads to progressive deterioration of the adjacent joint cartilages in a consistent repetitive sequence of arthritis. The purpose of this study was to investigate whether the capitate-triquetrum distance is related with the occurrence of carpal collapse in cases of static scapholunate instability. In this retrospective study, 41 patients formed two groups based on the capitate-triquetrum distance; twenty-four with distance of less than 5mm and 17 with distance of 5mm or more. No significant difference was detected with respect to age, sex distribution, dominant hand involvement, initial treatment and time from injury to final x-rays. Three patients (3/24, 12.5%) of the C-T < 5mm group and 10 patients (10/17, 58.8%) of the C-T ≥ 5mm group had no sign of carpal collapse. This difference was statistically significant (p=0.017). Capitate-triquetrum distance could reliably contribute in the decision making process in difficult cases of static scapholunate instability.
长期的舟月关节不稳定常导致相邻关节软骨按一致的重复性关节炎序列进行性退变。本研究的目的是探讨在静态舟月关节不稳定的病例中，头状骨-三角骨间距是否与腕骨塌陷的发生有关。在这项回顾性研究中，41例患者根据头状骨-三角骨间距分为两组；24例间距小于5mm，17例间距为5mm或更大。在年龄、性别分布、优势手受累情况、初始治疗以及受伤至最终X线检查的时间方面，未检测到显著差异。头状骨-三角骨间距<5mm组的3例患者（3/24，12.5%）和头状骨-三角骨间距≥5mm组的10例患者（10/17，58.8%）没有腕骨塌陷的迹象。这种差异具有统计学意义（p=0.017）。头状骨-三角骨间距可在静态舟月关节不稳定的疑难病例的决策过程中提供可靠依据。
