Area of Science:

  • Pain Management
  • Neurology
  • Radiology

Background:

  • Selective nerve block (SNB) is an established diagnostic and therapeutic imaging procedure.
  • It involves precise needle placement within the epiradicular space of the spine.

Purpose of the Study:

  • To describe the methodology of selective nerve blocks in the spine.
  • To highlight its utility in identifying symptomatic nerves and guiding treatment decisions.

Main Methods:

  • Needle insertion under fluoroscopic guidance into the epiradicular space.
  • Confirmation of needle position using nonionic contrast injection.
  • Administration of local anesthetic and/or corticosteroid, with pain reproduction and relief monitoring.

Main Results:

  • Successful identification of symptomatic nerves.
  • Variable duration of pain relief achieved.
  • Assistance in selecting appropriate candidates for surgery.

Conclusions:

  • Selective nerve block is an effective technique for spinal pain diagnosis and management.
  • It provides valuable information for patient stratification and treatment planning.
