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.
