Overview
The lateral finger radiograph profiles the phalanges to assess displacement and angulation. The digit is positioned true lateral with adjacent fingers separated. This view is essential for evaluating dorsal or volar displacement and joint alignment.
Technique
Place the finger in true lateral with the plane of interest parallel to the detector. Use a small focal spot and immobilize the digit to reduce motion. Collimate tightly to minimize dose and improve image quality.
Clinical Indications
Lateral finger is indicated for trauma suspected dislocation and assessment of angulation. It complements PA and oblique views for comprehensive evaluation. It guides management decisions for reduction and fixation.
Image Assessment
Assess dorsal or volar displacement and measure angulation when present. Evaluate joint congruity and soft tissue swelling. Report findings and recommend orthopedic consultation when indicated.
