Cervical CT-Guided, Selective Nerve Root Blocks: Improved Safety by Dorsal Approach: Fig 1.

Abstract

Cervical transforaminal blocks are frequently performed as a treatment of cervical radicular pain. These blocks are performed mostly under fluoroscopy, but a CT-guided technique also has been described. We describe a modification that leads to a more extraforaminal than transforaminal and equally selective nerve root block.
