Red dot indicates position of radial tuberosity which moves from:
- Anterior position in suppination
- Posteromedial in neutral rotation
- Lateral in pronation

Radial Head-Capitellum view
- Demostrates: Unobstructed view of radial head, capitellum, coronoid process, humeroradial/humeroulnar articulations • anteroinferior glenoid rim.

Postion: patient seated with forarm resting on the xray table on its ulnar side; elbow flexed 90°; thumb pointing up.
Beam: aimed at 45° angle from the forearm towards radial head
