Epiduroscopy for Chronic Lumbar and Radicular Pain

A Review of Recent Clinical Findings

Abstract

Introduction: Epiduroscopy has emerged as a minimally invasive diagnostic and therapeutic option for chronic low back and radicular pain. This review summarises evidence from the past five years to evaluate its role in contemporary clinical practice.

Methods: This review is based on selected peer-reviewed literature that addresses the mechanisms of action, diagnostic and therapeutic role, efficacy and safety of epiduroscopy in the treatment of chronic pain. Relevant literature was identified by searching PubMed and Scopus databases, published in the span of 2021.- 2026. The aim of this review is to present the contemporary use of epiduroscopy in the treatment of chronic lumbar and radicular pain with an emphasis on recent clinical studies and to summarize recent clinical findings on the use of epiduroscopy in clinical practice.

Discussion: Current evidence supports epiduroscopy as an effective treatment for Persistent Spinal Pain Syndrome type 2 (PSPS type 2, formerly called Failed Back Surgery Syndrome – FBSS), lumbar spinal stenosis and radicular pain. It may also serve as a transitional therapy that may delay or reduce the need for spinal cord stimulation (SCS). In addition, epiduroscopy enables targeted delivery of therapeutic agents, including platelet-rich plasma (PRP) and corticosteroids. Although generally safe, potential complications necessitate monitoring of intracranial pressure (ICP).

Conclusion: Epiduroscopy is a valuable tool in the management of chronic spinal pain and has an expanding role in clinical practice. However, the available evidence is limited by retrospective study designs and clinical heterogeneity, highlighting the need for well-designed randomised controlled trials.
