Overview
AP and lateral forearm radiographs evaluate the entire radius and ulna including wrist and elbow joints. These views are essential for detecting shaft fractures and assessing alignment. Proper positioning ensures both joints are included for comprehensive assessment.
Technique
Obtain AP view with the palm up and the forearm flat on the detector. For lateral view flex the elbow 90 degrees and superimpose the radius and ulna. Use appropriate exposure and immobilize the limb to reduce motion.
Clinical Indications
Forearm series are indicated for trauma pain and suspected shaft fractures or dislocations. They assess for malrotation and joint involvement. CT is used for complex fractures and preoperative planning.
Image Assessment
Inspect cortical continuity alignment and joint congruity at the wrist and elbow. Evaluate for plastic deformation in pediatric patients and growth plate involvement. Document displacement and recommend orthopedic follow up when indicated.
