Is the radius in the elbow?

Published in Anatomy 1 min read

Yes, part of the radius bone is located near the elbow.

While the radius is one of the two long bones in the forearm, extending from the elbow to the wrist, the radial head, which is the proximal (closest to the body) end of the radius, sits near the elbow joint. It doesn't form the elbow joint itself, but it articulates with the humerus (upper arm bone) and the ulna (the other forearm bone) at the elbow.

Here's a simplified breakdown:

  • Radius: A long bone in the forearm, located on the thumb side.
  • Radial Head: The upper (proximal) end of the radius, near the elbow.
  • Elbow Joint: Formed primarily by the humerus, ulna, and, to a lesser extent, the radius.

Therefore, although the radius is a forearm bone, its radial head is a crucial component near the elbow, playing a role in forearm rotation and stability. A fracture of the radial head is a common elbow injury.
