What to look for in normal shoulder radiograph
- Two orthogonal views: an AP (or true AP / Grashey) plus a scapular Y-view or axial view.
- On a standard AP the humeral head overlaps the glenoid in a smooth ellipse; on the Y-view it sits over the centre of the 'Y'.
- Work round the girdle: glenohumeral joint, proximal humerus, AC joint (inferior borders of acromion and clavicle level), clavicle and scapula.
