The outer
of the two bones of the forearm when viewed with the palm facing forward
is the radius and is shorter than the ulna.

The ulna
is the inner of the two bones of the forearm (when viewed with the palm
facing forward).
Fractures
of the ulna or radius are common in road traffic accidents. Spiral or
transverse fracture can occur with a fall or a direct trauma. These
fractures can be treated conservatively or surgically depending on the
severity or miss alignment of the fractures. X-rays will dictate what
type of treatments is required. Treatment should involve proper alignment
restoring the length of the appropriate bone.
