Overview
The PA finger radiograph evaluates phalanges and interphalangeal joints for fractures and dislocations. The finger is placed flat on the detector with slight separation from adjacent digits. This targeted view provides high resolution assessment of small bone injuries.
Technique
Center the detector to the affected digit and collimate tightly to reduce dose. Use a small focal spot and appropriate exposure for fine detail. Immobilize the finger and use positioning aids for comfort.
Clinical Indications
PA finger is indicated for trauma localized pain and suspected foreign body. It helps detect tuft fractures avulsions and joint subluxations. Additional oblique and lateral views complement the PA projection.
Image Assessment
Inspect cortical margins for fracture lines and evaluate joint spaces for subluxation. Look for soft tissue swelling and foreign bodies. Report findings and recommend follow up imaging if healing assessment is required.
