The purpose of this article is to review a number of diagnostic pitfalls related to ultrasound evaluation of the hand and wrist. Such pitfalls relate to evaluation of ten-dons (extensor retinaculum, multiple tendon fascicles, tendon subluxation), inflammatory arthritis (incomplete evaluation, misinterpretation of erosions, failure to evaluate for enthesitis), carpal tunnel syndrome (inaccurate measurements, postoperative assessment), ulnar collateral ligament of the thumb (misinterpretation of the adductor aponeurosis and displaced tear), wrist ganglion cysts (incomplete evaluation and misdiagnosis), and muscle variants.
Although ultrasound has been shown to be an effective imaging method for assessment of many pathologic conditions of the wrist, knowledge of potential pitfalls is essential to avoid misdiagnosis and achieve high diagnostic accuracy.
本文旨在回顾与手部和腕部超声评估相关的一些诊断陷阱。这些陷阱涉及到肌腱（伸肌支持带、多条肌腱束、肌腱半脱位）、炎性关节炎（评估不完整、侵蚀误读、忽视附着点炎）、腕管综合征（测量不准确、术后评估）、拇指尺侧副韧带（内收肌腱止点和移位撕裂的误读）、腕关节腱鞘囊肿（评估不完整和误诊）和肌肉变异等方面的诊断。
尽管超声已被证明是评估手腕多种病理情况的有效成像方法，但了解潜在的陷阱对于避免误诊和实现高诊断准确性至关重要。
