Development and Growth Plates In children and adolescents, these two bones are separated by a layer of cartilage known as the growth plate. X-rays are the standard diagnostic tool to visualize the alignment and integrity of the radius and ulna.
The ulna is located on the medial side (pinky finger side) and is longer than the radius, while the radius sits on the lateral side (thumb side) and allows for significant rotational movement. Anatomy of the Radius The radius is thinner and more compact, playing a crucial role in the rotation of the forearm.
