Overview

The lateral wrist radiograph assesses sagittal alignment of the carpus and distal radius. The hand is positioned in true lateral with the thumb side up. This view is important for evaluating dorsal or volar displacement and carpal instability.

Technique

Align the wrist so the radius and ulna are superimposed on the lateral projection. Use consistent positioning and include the distal forearm and metacarpals. Immobilize the hand to minimize motion and ensure reproducibility.

Clinical Indications

Lateral wrist is indicated for trauma suspected dislocation and assessment of carpal alignment. It complements PA and oblique views for comprehensive wrist evaluation. It is useful in preoperative planning and follow up.

Image Assessment

Assess dorsal and volar displacement of fractures and evaluate carpal height and alignment. Look for perilunate and lunate dislocations. Correlate with clinical findings and consider CT for complex injuries.
