Styloid process of the radius

Other Terms: Radial styloid process, Processus styloideus radii, Processus styloïde du radius


This pyramidal process sits on the distolateral end of the radius forming the distal most projection of the antebrachium. To the tip of the styloid process attaches the lateral carpal ligament, the lateral surface of the styloid serving as the attachment site for the brachioradialis muscle.


Styloid is derived from the Greek stylos meaning a pillar. In combination with eidos meaning like, this term literally means a pillar-like process. Process is a term used in anatomy to describe a projection on a bone. It comes from the Latin pro- meaning forward and cessus for gone. It is an old term that can be traced back to the writings of the early anatomist Celsus.
