[Evaluation of the efficacy of foraminal infusions of corticosteroids guided by computed tomography in the treatment of radicular pain by foraminal injection]

Abstract

Purpose: To evaluate the efficacy of foraminal steroid injections performed under CT guidance for the management of radicular pain.

Methods: Periganglionic infiltrations were performed in 160 patients with radicular pain refractory to medical treatment. Imaging showed either degenerative foraminal stenosis, herniated disk or postsurgical fibrosis.

Results: 102 patients (63.8%) had significant pain reduction. Pain relief was lasting in 68 (66.6%). CT showed the position of the needle tip, as well as the diffusion of the therapeutic compounds.

Conclusion: We consider that CT-guided periganglionic steroid injections should be an integral part of the management strategy for radicular pain resistant to medical treatment.
