Société d'imagerie musculosquelettique (SIMS), Fédération de radiologie interventionnelle (FRI), and Société Francophone de radiologie (SFR) recommendations for epidural and transforaminal corticosteroid injections.

Spinal injections of corticosteroids are routinely used in the treatment of lumbar and cervical radicular pain. These infiltrations are carried out at all spinal levels, essentially transforaminal, interlaminar, and through the facet joint or the sacrococcygeal hiatus. The purpose of these infiltrations is to eliminate inflammation (if present) involved in the pathogenesis of pain and to reduce or eliminate pain in the short term. The medium and long-term efficacy of these infiltrations is, however, difficult to assess given the frequent spontaneous partial or complete pain relief when nerve entrapment is due to a disc herniation.
