A patient comes to radiology for treatment of an arthritic condition of the right shoulder.The radiologist orders AP internal/external rotation projections and an inferosuperior axial projection of the scapulohumeral joint.However, the patient cannot abduct the arm for this projection.Which other projection will best demonstrate the scapulohumeral joint space?

The AP oblique (Grashey method) is the best projection in this scenario as it can demonstrate the scapulohumeral joint space without requiring the patient to abduct their arm. The other options, such as scapular Y lateral and inferosuperior axial projection, require arm abduction which the patient cannot do. The transthoracic lateral may show the scapulohumeral joint, but it is not ideal for showing the joint space. The AP projection-neutral rotation is also not ideal for demonstrating the joint space as it may show overlapping of the joint.
