It provides a stable, non-moving pivot point against which the radius rotates. The distal joint is near the wrist, where the radius and the ulna connect via an interosseous membrane.

The unique feature of the radius is its ability to rotate around the ulna, a motion that is fundamental to the supination and pronation of the forearm. A "broken wrist" often involves the distal radius.
The strength provided by these two bones allows for both powerful gripping and precise manipulation. Understanding their distinct anatomy and interconnected function is essential for appreciating how the upper limb operates.
Diagnosing Forearm Bone Injuries: Understanding Radius and Ulna Damage
Summary of Key Skeletal Components To visualize the anatomy, it is helpful to consider the following comparison of the two bones: Feature Radius Ulna Location Lateral (Thumb side) Medial (Pinky side) Primary Role Rotation, Wrist articulation Stability, Elbow formation Key Joint Proximal & Distal Radioulnar Joints Trochlear Notch. Anatomy of the Radius: The Lateral Stabilizer Positioned on the lateral side of the forearm, closer to the thumb, the radius is a long bone that plays a crucial role in the stability and movement of the wrist and hand.
