The findings of ultrasonography (US) of 52 tendons of the hands of 14 patients with chronic rheumatoid arthritis (RA) were compared with operative findings obtained subsequently. US showed tenosynovitis as expansion of a hypoechoic area around the tendon. US also enabled pattern classification based on shape, internal echo and border features of the scanned tendon, differentiation of acute and progressive stages among acute inflammation, invasion of tenosynovitis, degeneration, and rupture of the tendon to be made, and the progression of tendon lesions could be ascertained. It was found that in inflammation the tendon was significantly thickened, and in degeneration, the tendon was thinned. By dynamic US scanning, disturbances of tendon movement due to tendon rupture and adhesion to surrounding structures could be detected and differentiated. It was found in this study that preoperative US of the hand of RA patients is very useful for early diagnosis and for the selection of treatment including operative methods.
对14例慢性类风湿性关节炎（RA）患者手部的52条肌腱进行超声检查（US），并将检查结果与随后的手术结果进行比较。超声显示腱鞘炎为肌腱周围低回声区扩大。超声还能够根据扫描肌腱的形状、内部回声和边界特征进行模式分类，区分急性炎症、腱鞘炎侵犯、退变和肌腱断裂中的急性和进展期，并确定肌腱病变的进展情况。研究发现，在炎症状态下肌腱明显增厚，而在退变时肌腱变薄。通过动态超声扫描，可以检测并区分因肌腱断裂和与周围结构粘连而导致的肌腱运动障碍。本研究发现，RA患者手部的术前超声检查对早期诊断以及包括手术方法在内的治疗选择非常有用。
