Answer: Normal shoulder radiograph
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.
Description by the image author (may be in another language): Anteroposterior glenoid ("Grashey view") projectional radiograph ("X-ray") of the right shoulder of a 31 year old man with recurrent shoulder dislocation . It shows no skeletal or soft tissue abnormalities (the malfunctioning rotator cuff is not seen).
Educational case. The diagnosis comes from the image's documented source; the "what to look for" list describes the condition in general and is not a report of this individual image.
