High-frequency (5.0 and 7.5 MHz) ultrasonography (US) was performed in 16 patients with rheumatoid involvement of soft tissues in the hand or wrist; surgery was performed in 11. In 15 (94%) patients, a hypoechoic thickening of one or several tendon sheaths was noted. The thickening ranged from 2 to 13 mm (mean, 5.2 mm +/- 3.0). Complete or partial flexor tendon ruptures were correctly suspected preoperatively at real-time dynamic US examination in three patients. A discrete, elongated, hypoechoic soft-tissue nodule was demonstrated in five patients; one nodule was intra-tendinous. In 10 of 11 patients, US findings correlated well with those of surgery. Real-time US proved highly accurate in demonstrating rheumatoid soft-tissue changes in the hand. A hypoechoic rim around a tendon in the hand or wrist in a patient with rheumatoid arthritis is highly suggestive of rheumatoid tenosynovitis. US also provides surgeons with an accurate preoperative map of the lesions.
对16例手部或腕部软组织类风湿性病变患者进行了高频（5.0和7.5兆赫）超声检查；其中11例患者接受了手术。15例（94%）患者可见一个或多个腱鞘低回声增厚。增厚范围为2至13毫米（平均5.2毫米±3.0）。3例患者在术前实时动态超声检查中被正确怀疑存在完全或部分屈肌腱断裂。5例患者显示有离散的、细长的、低回声软组织结节；1个结节位于肌腱内。11例患者中有10例超声检查结果与手术结果高度相关。实时超声在显示手部类风湿性软组织变化方面证明非常准确。类风湿性关节炎患者手部或腕部肌腱周围的低回声边缘高度提示类风湿性腱鞘炎。超声还为外科医生提供了准确的术前病变图谱。
