Tenosynovitis of one or more flexor tendons of the hand (mean 3.1 tendons per patient) was noted in 55% of 100 patients with rheumatoid arthritis (RA) examined periodically during a mean period of 5 years. The third flexor tendon was involved most frequently (71% of patients), followed by the second (62%), fourth (53%), fifth (27%), and first (13%). Patients with flexor tendonitis (FT) had a significantly higher prevalence of rheumatoid nodules (56% vs 33%), carpal tunnel syndrome (47% vs 13%), wrist extensor tenosynovitis (47% vs 9%), and elbow epicondylitis (22% vs 7%) than patients without FT. Dupuytren's contracture, DeQuervain's tenovaginitis, flexor carpi radialis and ulnaris tendonitis, and Achilles tendonitis were found exclusively in patients with FT. A control group of 50 non-RA patients with FT had statistically fewer diseased tendons per patient (mean 1.5) and a different digital distribution, the thumb being affected more frequently (P less than 0.05) than in RA patients.
在对100例类风湿关节炎（RA）患者进行平均为期5年的定期检查中，发现55%的患者存在手部一根或多根屈肌腱腱鞘炎（平均每位患者3.1根肌腱）。第三屈肌腱受累最为常见（71%的患者），其次是第二屈肌腱（62%）、第四屈肌腱（53%）、第五屈肌腱（27%）和第一屈肌腱（13%）。与无屈肌腱炎（FT）的患者相比，屈肌腱炎患者类风湿结节的患病率显著更高（56%对33%）、腕管综合征（47%对13%）、腕伸肌腱腱鞘炎（47%对9%）和肘上髁炎（22%对7%）。掌腱膜挛缩、桡骨茎突狭窄性腱鞘炎、桡侧腕屈肌腱和尺侧腕屈肌腱炎以及跟腱炎仅在屈肌腱炎患者中发现。50例非RA的屈肌腱炎患者组成的对照组，每位患者的患病肌腱在统计学上更少（平均1.5根），且手指分布不同，拇指受累比RA患者更频繁（P小于0.05）。
