Ultrasonography (US) of the elbow is an increasingly utilized modality for a variety of diagnoses. US is advantageous in many cases because of the ability to perform a dynamic examination while obtaining patient feedback. Furthermore, US is cost effective, widely available, and beautifully demonstrates superficial soft tissue structures. Finally, US is an excellent option for patients whose studies are degraded by motion artifact or those with claustrophobia concerns. The most common pathologies about the elbow are discussed in this article, including partial- and full-thickness tears of the biceps and triceps tendons, common extensor and flexor tendinosis, medial and lateral epicondylitis, radial and ulnar collateral ligament tears, ulnar nerve entrapment, cubital or olecranon bursitis, joint effusions, and intra-articular bodies. Relevant anatomy is detailed as it pertains to sonographic evaluation and appearance. In addition, specific imaging techniques and positions are described for optimum visualization of the various structures around the elbow because US is highly operator dependent.
超声检查（US）肘部在多种诊断中越来越多地被采用。由于能够在获取患者反馈的同时进行动态检查，超声在许多情况下具有优势。此外，超声成本效益高、广泛可用，并且能很好地显示浅表软组织结构。最后，对于因运动伪影导致检查效果不佳的患者或有幽闭恐惧症的患者，超声是一个极佳的选择。本文讨论了肘部最常见的病变，包括肱二头肌和肱三头肌腱的部分和全层撕裂、常见伸肌和屈肌腱病、内侧和外侧上髁炎、桡侧和尺侧副韧带撕裂、尺神经卡压、肘或鹰嘴滑囊炎、关节积液和关节内游离体。详细介绍了与超声评估和表现相关的解剖结构。此外，还描述了特定的成像技术和体位，以便最佳地显示肘部周围的各种结构，因为超声高度依赖操作者。
