The ulna is a long bone in the forearm
, located at its inner side while the radius, the second bone in the forearm, and is located at the outer side. The ulna meets up with the radius and humerus
(the bone going from the elbow
to the shoulder
) up around the elbow joint
, and with the radius and the carpal bones, down around the wrist
joint. This is a bone that can be fractured during trauma, often at the lower end near the wrist, and sometimes associated with a fracture of the radius in the same area.
