Overview
The radial head view profiles the radial head and neck to detect subtle fractures and impaction injuries. The projection is obtained with the elbow flexed and the beam angled to profile the radial head. This view complements standard AP and lateral elbow radiographs.
Technique
Position the elbow in partial flexion and rotate the hand to profile the radial head. Use a small focal spot and tight collimation for detail. Immobilize the limb to minimize motion artifact.
Clinical Indications
Radial head views are indicated for trauma with lateral elbow pain and suspected radial head fracture. They help detect nondisplaced fractures that may be occult on standard views. CT or MRI may be used for complex or occult injuries.
Image Assessment
Evaluate radial head cortical continuity articular surface and neck for fracture lines. Assess for joint effusion and associated capitellar injury. Report findings relevant to orthopedic management.
