Shoulder dislocation is an injury with potential long-term consequences that requires prompt diagnosis and treatment. Patient positioning and imperfect radiographic views may result in discomfort, added examination time, and problematic diagnosis. The scapular Y radiograph has been shown to be useful in diagnosing shoulder dislocation but is not considered sufficient in isolation. Using a synthetic bone shoulder model, we propose a novel technique wherein osseous landmarks are used to form angles that significantly improved diagnostic accuracy for shoulder dislocation, even in significantly rotated and otherwise indeterminate scapular Y radiographs.
肩关节脱位是一种可能产生长期后果的损伤，需要及时诊断和治疗。患者体位及不完美的X线片可能导致不适、增加检查时间以及诊断困难。肩胛Y位X线片已被证明对诊断肩关节脱位有用，但单独使用并不被认为足够。我们使用一个合成骨肩部模型，提出了一种新技术，即利用骨性标志形成角度，即使在肩胛Y位X线片显著旋转及其他不确定的情况下，也能显著提高肩关节脱位的诊断准确性。
