Radial Head Fractures
Key Points
The radial head is tender, and pain is worse during supination. Take anteroposterior, lateral, and oblique x-rays, but because x-rays may show only indirect evidence of fracture, physical examination is very important in diagnosis. If the radial head is tender and clinical or radiographic evidence suggests an elbow effusion, treat presumptively for radial head fracture even if the x-ray shows no fracture.
