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.
