The weighted abduction Grashey shoulder method.

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.
