Palmar radio-ulnar ligament

Looks like

A band on the palm side of the lower forearm joint, from the radius to the base of the ulnar styloid, part of the TFCC.

What it does

Holds the lower ends of radius and ulna together as the forearm turns.

Keeping it well

Torn in wrist fractures and sprains, causing an unstable, clicking wrist on turning the palm.
