Direct intraforaminal steroid injections effectively treat radicular pain, especially when caused by degenerative foraminal stenosis. This minimally invasive procedure offers significant pain reduction for many patients.

Area of Science:

  • Pain Management
  • Neurosurgery
  • Radiology

Background:

  • Radicular pain significantly impacts patient quality of life.
  • Foraminal stenosis, caused by degenerative disorders or herniated discs, is a common cause of radicular pain.
  • Minimally invasive interventions are sought for effective pain relief.

Purpose of the Study:

  • To evaluate the efficacy of direct intraforaminal steroid injections.
  • To assess the effectiveness of periganglionic steroid injections in the treatment of radicular pain.

Main Methods:

  • 41 patients with acute or chronic radicular pain underwent periganglionic infiltrations.
  • Neuroradiologic imaging confirmed foraminal stenosis in all patients.
  • All steroid injections were performed under computed tomography (CT) guidance.

Main Results:

  • 70% of patients experienced significant pain reduction following the procedure.
  • Success rates were higher in patients with degenerative foraminal stenosis (90% pain relief).
  • 45% of patients with foraminal herniated discs reported pain relief.

Conclusions:

  • Direct intraforaminal steroid injection is a valuable treatment for radicular pain.
  • The procedure demonstrates particular utility in managing radicular pain associated with foraminal degenerative stenosis.
