Ulnar styloid process

Looks like

A small peg at the lower end of the ulna on the little-finger side of the wrist.

What it does

Anchors the cartilage disc and ligaments that steady the wrist on the little-finger side.

Keeping it well

Often chipped along with a broken wrist, usually without trouble. Clicking and pain on this side when turning the forearm point to the cartilage disc (TFCC).
