The purpose of this study was to assess tendon compressibility with sonography in extensor tendinopathy and in asymptomatic extensor tendons of the elbow. Sonography of both elbows was performed in eight patients with a clinical diagnosis of unilateral lateral epicondylitis. Tendons were assessed for compressibility by measuring their thickness before and after compression with the transducer. The same manoeuvre was performed while tendon vascularity was assessed with colour Doppler. All eight cases showed increased compressibility of the common extensor tendon on the painful side compared to the asymptomatic side, as well as increased vascularity with compressible vessels on colour Doppler. Other signs of tendinopathy were hypoechogenicity (n = 8), loss of fibrillar pattern (n = 8), intratendinous calcifications (n = 1), partial tears (n = 3), and enthesophytes (n = 5). Increased tendon compressibility indicative of tendon softening or "tenomalacia" is a new sonographic sign of common extensor tendinopathy.
本研究的目的是利用超声评估伸肌肌腱病患者及肘部无症状伸肌肌腱的肌腱可压缩性。对8例临床诊断为单侧外侧上髁炎的患者双侧肘部进行超声检查。通过用探头在压缩肌腱前后测量其厚度来评估肌腱的可压缩性。在用彩色多普勒评估肌腱血管情况时进行同样的操作。与无症状侧相比，所有8例患者疼痛侧的伸肌总腱可压缩性均增加，且彩色多普勒显示可压缩血管的血管增多。肌腱病的其他表现包括低回声（n = 8）、纤维结构消失（n = 8）、肌腱内钙化（n = 1）、部分撕裂（n = 3）和骨赘（n = 5）。提示肌腱软化或“肌腱软化症”的肌腱可压缩性增加是伸肌总腱肌腱病的一种新的超声表现。
