The AP (anteroposterior) view of the scapula is an X‑ray projection with the beam directed anterior-to-posterior, centered on the scapular body. It visualizes the entire scapula—acromion, coracoid, glenoid and body—separated from the thoracic cage. Performed upright or supine with the arm positioned to move the scapula laterally, it assesses fractures, dislocations and other bony pathology.

Standard scapular radiographic views are: AP (true anteroposterior) to evaluate the body and lateral border; lateral scapula (scapular Y view) for the spine, acromion and glenoid; and axillary lateral to visualize the glenoid fossa and acromioclavicular relationship. If the arm cannot be abducted, a modified axillary (Velpeau) or trauma lateral is used.

AP (anteroposterior) and Lat (lateral) are X‑ray view orientations. AP means the X‑ray beam travels from front to back (commonly used for supine or portable exams) and may magnify cardiac/mediastinal structures. Lat is a side‑to‑side view, with the beam passing laterally at 90°, giving depth information and helping localize abnormalities not well seen on AP images.

Place the patient erect or supine with the affected side against the image receptor. Rotate the patient 45–60° so the scapula lies lateral to the rib cage. Have the patient cross the arm over the chest or rest the hand on the opposite shoulder to move the scapula laterally. Direct the central ray perpendicular to mid-scapula, include acromion to inferior angle, collimate, shield, and hold still.

For an AP scapula, place the patient erect or supine with the affected side against the image receptor. Abduct the arm to 90° and externally rotate the shoulder to move the scapula laterally off the chest. Center the scapular body on the receptor; direct the central ray perpendicular to the mid‑scapula (about 2 inches inferior to the coracoid). Suspend respiration for the exposure.

AP (anteroposterior) and PA (posteroanterior) describe X‑ray beam direction. In PA, the beam passes from back to front with the patient standing facing the detector; this reduces cardiac magnification and gives more accurate heart and mediastinal size. In AP, the beam passes front to back—often used supine or portable—producing increased apparent heart size, altered clavicle/scapular positions, and different lung markings to consider.
