The Grashey shoulder position is used to demonstrate damage to the glenohumeral joint caused by osteoarthritis, sclerosis, tumors, fractures, osteophytes and cystic changes. However, it can be difficult to assess loss of articular cartilage using the Grashey shoulder position because little axial load is applied to the glenohumeral joint. This article describes a method of creating a loading force across the glenohumeral joint by adding weighted arm abduction during the Grashey position to demonstrate loss of the articular cartilage. Case studies and radiographs are presented to discuss the advantages of using the Grashey position with weighted abduction.
格拉西肩部投照位用于显示由骨关节炎、骨质硬化、肿瘤、骨折、骨赘和囊性变引起的盂肱关节损伤。然而，使用格拉西肩部投照位评估关节软骨损伤可能会有困难，因为施加到盂肱关节的轴向负荷较小。本文介绍了一种在格拉西投照位时通过增加负重臂外展来在盂肱关节上产生加载力的方法，以显示关节软骨损伤。文中呈现了病例研究和X线片，以探讨使用负重外展的格拉西投照位的优势。
