The rotator interval (RI) is a critical but complex anatomical structure for which musculoskeletal ultrasound provides an excellent imaging evaluation. In the patients with restricted and painful movements, the RI may not be visualised optimally as the conventional 'Modified Crass' positions may not be achievable. It can also be difficult to optimally evaluate the anterior supraspinatus and subscapularis tendons in such patients. We describe a simple shoulder position obviating need of pronounced supraspinatus stretch for better evaluation of the rotator interval and adjoining rotator cuff structures.
旋转间隔（RI）是一个关键但复杂的解剖结构，肌肉骨骼超声为此提供了极好的影像学评估。在活动受限和疼痛的患者中，由于常规的“改良 Crass”体位可能无法达到，RI 可能无法得到最佳可视化。在这些患者中，也很难对前肩袖上肌和肩胛下肌肌腱进行最佳评估。我们描述了一种简单的肩部位置，避免了明显的肩袖上肌拉伸，从而可以更好地评估旋转间隔和相邻的肩袖结构。
