radius
Let an agent explain the radius bone and its anatomy, relay structure, function, development and injuries from anatomy and orthopaedic sources in general terms, describe right and left radii, and distinguish the bone from the ulna and from the geometric radius, routing injuries to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the radius bone and its anatomy, relay structure, function, development and injuries from anatomy and orthopaedic sources in general terms, describe right and left radii, and distinguish the bone from the ulna and from the geometric radius, routing injuries to clinicians.
One of the two long bones of the forearm, lying on the thumb side parallel to the ulna, articulating with the humerus and ulna at the elbow and with the carpal bones and ulna at the wrist, rotating around the ulna in pronation and supination; the radius, present as right and left, is the most commonly fractured bone in the arm, especially at the distal end in falls on the outstretched hand.
What it is for: Not applicable; a bone.
It can be explain anatomy; relay function and injuries; route to clinicians; distinguish related concepts.
Distinguishing features
Forearm long bone
Thumb side
Rotates in pronation
Common fracture site
What it looks like
A long bone with a small round head at the elbow and a broad end at the wrist.
Physical character
length, adult: about 20-26 cm
articulations: humerus, ulna, scaphoid, lunate list
distal radius fractures: about 1 in 6 fractures note - emergency departments
How it is recognised
Lateral long bone of the forearm
Right radius, left radius
The ulna is the medial forearm bone; the geometric radius is a line
