Determining the progression of anatomic involvement in rheumatoid arthritis (RA) is a well recognized problem. In 1976, Trentham and Masi described the carpometacarpal (CMC) ratio and found it useful for detecting progression of anatomic involvement in RA. Our study attempts to validate the efficacy of this ratio both in a cross sectional (n = 267) and longitudinal (n = 53) sample of patients with rheumatoid arthritis. Our data indicate that the CMC ratio is useful for quantitating anatomic involvement and correlates well with anatomic progression over time.
确定类风湿性关节炎（RA）中解剖学受累的进展是一个公认的问题。1976年，特伦瑟姆和马西描述了腕掌（CMC）比率，并发现它有助于检测RA中解剖学受累的进展。我们的研究试图在横断面（n = 267）和纵向（n = 53）的类风湿性关节炎患者样本中验证该比率的有效性。我们的数据表明，CMC比率有助于量化解剖学受累情况，并且与随时间推移的解剖学进展密切相关。
