Hand Oblique
4
Feb

Overview

The oblique hand radiograph rotates the hand approximately 45 degrees to profile metacarpals and phalanges. This projection reduces overlap and improves detection of fractures. It is routinely obtained with PA and lateral views for comprehensive assessment.

Technique

Rotate the hand laterally about 45 degrees and center the detector to the third metacarpal. Ensure consistent rotation and immobilize the hand to minimize motion. Use appropriate collimation to include the entire hand.

Clinical Indications

Oblique hand views are indicated for trauma and suspected occult fractures. They help visualize metacarpal neck and shaft injuries and joint subluxations. Correlate with clinical exam and consider CT for complex fractures.

Image Assessment

Inspect cortical margins for fracture lines and evaluate joint congruity. Assess for rotational deformity and malalignment. Report findings and recommend orthopedic follow up when indicated.

Hand Lateral

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.
