The Radial Styloid Process is a bony protrusion located at the distal end of the radius bone in the human forearm. It is an important anatomical landmark in the wrist, playing a crucial role in the stability and movement of the joint.

Anatomy

The radial styloid process is a pointed projection located on the lateral side of the radius, just proximal to the thumb. It serves as an attachment site for several ligaments, including the brachioradialis, radial collateral ligament, and part of the scapholunate ligament.

Clinical Significance

The radial styloid process is often involved in wrist injuries, such as Colles' fracture and Smith's fracture. It can also be affected by De Quervain's tenosynovitis, a condition that causes pain and swelling in the wrist.
