Key points

The radius is the long bone on the thumb side of the forearm in anatomical position.
Its small upper end meets the humerus and ulna, while its broad lower end contributes to the wrist joint.
The radial head, radial tuberosity, ulnar notch and radial styloid process are important landmarks.
The radius rotates around the ulna during movements that turn the palm forwards or backwards.
