Different ultrasound approaches have been proposed to evaluate the distal biceps brachii tendon, such as lateral, posterior, medial, and anterior, all allowing good visualization of the distal biceps tendon and its pathologic appearances. Here we describe a new method of ultrasound evaluation of the distal biceps tendon insertion with the patient in the so-called crab position. The crab position is used to evaluate the posterior compartment of the elbow but also the lateral and medial compartments. This position allows for coverage of 75% the elbow in a single position, with less discomfort for the patient and a fair amount of saved time. In this position, after the evaluation of the common extensor tendon in the long axis, turning the transducer 90° and moving it distally allows for optimal visualization of the distal biceps brachii tendon in the axial plane. It is a simple, quick approach that allows for excellent visualization of the insertion of the distal biceps brachii tendon while avoiding an anisotropic effect.
已经提出了不同的超声检查方法来评估肱二头肌远端肌腱，如外侧、后侧、内侧和前侧，所有这些方法都能很好地显示肱二头肌远端肌腱及其病理表现。在此，我们描述一种患者处于所谓螃蟹位时对肱二头肌远端肌腱止点进行超声评估的新方法。螃蟹位用于评估肘部的后侧间室，也用于评估外侧和内侧间室。该体位可在单一位置覆盖肘部75%的范围，患者不适感较轻，且可节省大量时间。在此体位下，在长轴方向评估伸肌总腱后，将探头旋转90°并向远端移动，可在轴向平面上最佳地显示肱二头肌远端肌腱。这是一种简单、快速的方法，可在避免各向异性效应的同时，很好地显示肱二头肌远端肌腱的止点。
