The carpus-to-digits distance measured on a posteroanterior roentgenogram of the hands and wrists takes into account 18 different joints. This study demonstrates that the carpus-to-digit distance is a simple, reproducible score which reliably reflects progression of roentgenological rheumatoid arthritis lesions and is correlated with Larsen's lesion score and with Steinbrocker's index, but not with Larsen's erosion score during the first two years after onset of the disease. Larsen's erosion score and similar parameters should be preferred for clinical studies of recent-onset rheumatoid arthritis. The carpus-to-digit distance, which requires neither a reference film not observer training, is appropriate for long-term clinical studies.
在手和腕关节的后前位X线片上测量的腕指距离涉及18个不同关节。本研究表明，腕指距离是一个简单、可重复的评分，能可靠地反映类风湿性关节炎X线病变的进展，且与拉森病变评分和斯坦布鲁克指数相关，但在疾病发作后的头两年与拉森侵蚀评分无关。对于近期发病的类风湿性关节炎的临床研究，应优先选择拉森侵蚀评分及类似参数。腕指距离既不需要参照片，也不需要观察者培训，适用于长期临床研究。
