X Ray Left Index Finger AP View

The AP (anteroposterior) view of the finger is an X‑ray projection where the beam passes from anterior (palmar) to posterior (dorsal) through the digit. The finger is extended and placed flat on the detector with the palmar surface down, the central ray aimed at the PIP joint. It shows bone, joint spaces and alignment to assess fractures, dislocations and arthritis.

AP view (anteroposterior) means the X‑ray beam travels from the front (anterior) to the back (posterior) of the body. The patient’s back is usually against the detector or the beam source is positioned in front. It’s used when a PA view isn’t possible, but AP projections can magnify anterior structures and may make the heart and lungs appear larger than on PA views.

Standard finger X‑ray includes three views: PA (or AP) to assess joint spaces and bone alignment, an oblique (about 45°) to reveal fractures hidden on PA, and a lateral to evaluate displacement and soft‑tissue profile. Images should be centered on the affected digit from the distal phalanx through the metacarpophalangeal joint, with appropriate collimation and immobilization.

A standard finger X‑ray normally includes three views: an AP (or PA) view, an oblique view, and a lateral view. These three projections provide thorough evaluation of bone alignment, fractures, and joint spaces. In some settings two views may be taken initially, but three views are generally recommended for accurate diagnosis; additional tailored views can be added if needed.

AP (anteroposterior) view means the x‑ray beam travels from anterior to posterior. Position the patient upright or supine with the detector posterior, midline perpendicular to the detector, and the area of interest centered. Use appropriate source‑to‑image distance, place side markers and shielding, instruct full inspiration for chest exams, and immobilize to avoid motion artefact.

The left index finger is the second digit of the left hand, located between the thumb (radial side) and the middle finger. It consists of three phalanges (proximal, middle, distal) with metacarpophalangeal and interphalangeal joints. It contains bones, muscles, tendons, blood vessels and sensory nerves, enabling fine touch, grip and dexterous movements. It’s primarily innervated by the median nerve.
