Wrist Lateral
4
Feb

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.

Hand Lateral
4
Feb

Overview

The lateral hand radiograph evaluates sagittal alignment of the digits and metacarpals. The hand is positioned with fingers superimposed and the thumb slightly abducted. This view is useful for assessing displacement and rotational deformity.

Technique

Place the hand in true lateral with the ulnar side down and ensure fingers are aligned. Use a short exposure time to minimize motion and include the wrist when indicated. Immobilize the hand for reproducible positioning.

Clinical Indications

Lateral hand is indicated for trauma suspected dislocation and evaluation of foreign bodies. It complements PA and oblique views for comprehensive assessment. It is essential for preoperative planning in complex injuries.

Image Assessment

Evaluate dorsal or volar displacement of fractures and inspect for rotational malalignment. Assess joint congruity and soft tissue swelling. Document findings relevant to surgical planning and rehabilitation.
