True AP View

Position – Patient is erect or sitting with arm in sling or shoulder internally rotated. Affected scapula is flat against the x-ray cassette.

X-ray Beam – Directed perpendicular to the scapula and x-ray cassette, i.e., angled 45-degrees to frontal plane of thorax.

Demonstrates – Glenohumeral joint with glenoid seen in profile separate from the humeral head. Best view to demonstrate glenohumeral arthrosis.
