Overview
The PA hand radiograph evaluates phalanges metacarpals and carpometacarpal joints for fractures and arthritis. The palm is placed flat on the detector with fingers extended. This view is standard for hand trauma and chronic disease assessment.
Technique
Center the detector to the third metacarpal and ensure fingers are parallel and separated slightly. Use appropriate exposure and immobilize the hand to reduce motion. Include the distal forearm when indicated for wrist pathology.
Clinical Indications
PA hand is indicated for trauma deformity and suspected infection or arthritis. It helps detect fractures dislocations and erosive changes. Additional oblique and lateral views provide complementary information.
Image Assessment
Evaluate cortical continuity joint spaces and alignment of the metacarpals and phalanges. Look for subluxation and periarticular erosions in inflammatory disease. Document findings relevant to surgical or conservative management.
