Sacral block

Last edited and medically reviewed by Alaric Steinmetz on 29.04.2026

For a sacral block, a thin needle is advanced into the outer end of the epidural space of the Spine, and a local anesthetic, with or without a corticosteroid preparation, is administered locally[^1].

Imaging

A sacral block is performed with the aid of fluoroscopy.
