Between 1997 and 2006, radiographs of 66 scaphoid fractures were retrospectively reviewed to evaluate ulnar variance. Twenty-one (31.8%) patients had an 'ulna neutral' wrist, six (9.1%) had an 'ulna plus' and 39 (59.1%) had an 'ulna minus' wrist. The mean ulnar variance was -1.3 (SD 1.8) mm (range -5.5, 2.5). We observed a significant difference in the distribution of ulnar variance (P < 0.00001) and in the proportion of cases with ulna minus (OR = 5.0; 95% CI: 2.7, 9.3) compared to previous publications.
1997年至2006年间，对66例舟状骨骨折的X线片进行回顾性分析，以评估尺骨变异情况。21例（31.8%）患者腕关节为“尺骨中立位”，6例（9.1%）为“尺骨正向变异”，39例（59.1%）为“尺骨负向变异”。平均尺骨变异为-1.3（标准差1.8）毫米（范围-5.5至2.5）。与以往的研究相比，我们观察到尺骨变异的分布存在显著差异（P < 0.00001），尺骨负向变异的病例比例也有显著差异（比值比=5.0；95%置信区间：2.7至9.3）。
