Cervical CT-guided, selective nerve root blocks: improved safety by dorsal approach

AJNR Am J Neuroradiol. 2009 Feb;30(2):336-7. doi: 10.3174/ajnr.A1222. Epub 2008 Jul 24.


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.
