Finger PA
4
Feb

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.

Finger Oblique

Overview

The oblique finger radiograph rotates the digit to separate cortical margins and reveal fracture lines. This projection reduces overlap and enhances detection of small fractures. It is routinely obtained with PA and lateral views for complete evaluation.

Technique

Rotate the finger approximately 45 degrees and center the detector to the affected phalanx. Use tight collimation and a small focal spot for optimal detail. Ensure patient comfort and immobilize the digit to minimize motion.

Clinical Indications

Oblique finger views are indicated for trauma and suspected occult fractures. They help visualize avulsion fragments and joint surface involvement. Correlate with clinical findings and consider follow up radiographs for healing.

Image Assessment

Evaluate cortical continuity and joint alignment and look for small intra articular fragments. Assess soft tissue swelling and tendon avulsion sites. Document findings relevant to orthopedic management.

Finger Lateral

Feb

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.
