The AP (anteroposterior) view of the finger is an X‑ray taken with the beam directed from the front toward the back of the digit. The finger is extended and centered on the image receptor so the beam passes through the phalanges and interphalangeal joints. It shows bone alignment, joint spaces, fractures, dislocations and foreign bodies, and is usually supplemented by oblique and lateral views.

AP (anteroposterior) and Lat (lateral) describe X‑ray projection directions. AP means the X‑ray beam travels from the front (anterior) to the back (posterior) of the body — commonly used when patients are supine or cannot stand. Lateral means the beam passes from one side to the other, giving a side view. Both projections help localize structures, assess alignment, and reveal obscured pathology.

Finger lateral X‑ray: seat the patient with the forearm on the table and elbow flexed 90°. Place the affected finger in a true lateral—side of the finger against the image receptor—so the finger’s palmar surface is perpendicular to the receptor. Ensure other fingers are moved away or supported, collimate from distal phalanx to distal metacarpal, and centre the beam at the PIP joint.

A finger X‑ray typically requires three views — PA (or AP), lateral and oblique — to evaluate fractures, joint alignment, and soft‑tissue relationships. These three projections improve detection of small fractures and displacement. Additional or specialized views (e.g., skyline, stress, or comparison views) may be taken for complex injuries, pre/post‑reduction assessment, or when initial images are inconclusive.

An AP view is an anteroposterior radiographic projection where the X‑ray beam travels from the front (anterior) of the body to the back (posterior) and onto the detector. It’s often used for portable or supine patients who cannot stand. AP images can enlarge the cardiac silhouette and alter mediastinal appearance compared with a PA (posterior‑anterior) chest view.

The index finger (pointer) is the second digit of each hand, positioned between the thumb and middle finger. It extends from the hand’s second metacarpal and consists of three phalanges (proximal, middle, distal) with associated joints and tendons. Prominent in pointing and precision grips, it ends at the fingertip and works with the thumb for fine manipulation and dexterity.
