The proximal joint is located near the elbow, where the head of the radius meets the ulna. Anatomy of the Ulna: The Medial Anchor Running along the medial side of the forearm, closer to the little finger, is the ulna.
Forearm Mechanics: How the Radius and Ulna Work Together
Understanding their distinct anatomy and interconnected function is essential for appreciating how the upper limb operates. This bone is longer than the radius and serves as the primary anchor for the muscles that move the wrist and fingers.
The distal joint is near the wrist, where the radius and the ulna connect via an interosseous membrane. It provides a stable, non-moving pivot point against which the radius rotates.

The Radioulnar Joints: Enabling Rotation The functionality of the forearm hinges on the two radioulnar joints, which are the proximal and distal radioulnar joints. These bones work in concert to facilitate a wide range of motion, from the simple act of lifting a cup to the complex mechanics of a tennis serve.
