Intercornual ligament

Looks like

A small ligament joining the horns (cornua) of the sacrum to those of the coccyx at the bottom of the spine.

What it does

Part of the fibrous link between sacrum and coccyx.

Keeping it well

Mainly a landmark: the sacral hiatus beside it is the entry point for caudal epidural injections.
