The Grashey method is the best alternative projection for demonstrating the scapulohumeral joint space when the patient cannot abduct the arm. This projection requires the patient to be positioned in a posterior oblique position, and the central ray is directed through the scapulohumeral joint. The AP internal/external rotation projections and inferosuperior axiolateral projection are not suitable when the patient cannot abduct the arm. The scapular Y lateral and transthoracic lateral views are not appropriate for demonstrating the scapulohumeral joint space.
