Radial styloid process

Processus styloideus radii

How to find it
On the thumb side of the wrist, the distal end of the radius. It normally reaches about a centimetre further down than its counterpart on the little finger side.
What you use it for
Reference for radial inclination after a distal radius fracture; the Finkelstein test hurts right across it in de Quervain tenosynovitis.
