Procedures & Treatment Options
Epidural Steroid
Injections.
Epidural steroid injections are image-guided procedures that may be considered for selected patients with radicular pain or suspected nerve root irritation. A formal clinical evaluation is required to determine whether this procedure is appropriate for an individual patient.
In Brief
Image-Guided Procedure
Epidural steroid injections deliver anti-inflammatory medication near irritated spinal nerve roots under imaging guidance.
For Selected Patients
They may be considered for patients with radicular pain or suspected nerve root irritation when appropriate clinical criteria are met.
Response Varies
The procedure is not appropriate for every patient. Risks, benefits, and realistic expectations should be discussed before any procedure is performed.
Overview
What Are Epidural Steroid Injections?
Epidural steroid injections (ESIs) are procedures that deliver corticosteroid medication into the epidural space — the area surrounding the spinal cord and nerve roots inside the spinal canal. The goal is to reduce inflammation around irritated or compressed nerve roots, which may help reduce associated pain, numbness, or tingling.
The procedure is typically performed under fluoroscopic (X-ray) or other imaging guidance to confirm accurate needle placement. ESIs are not a structural treatment and do not repair underlying disc or spinal pathology.
Approaches
Injection Approaches.
Different injection approaches may be used depending on the patient's anatomy, diagnosis, and clinical situation:
Interlaminar Epidural
Medication is delivered through the back of the spine into the epidural space, providing broader coverage of the epidural area.
Transforaminal Epidural
Medication is delivered near a specific nerve root foramen, allowing more targeted treatment of a particular nerve level.
Caudal Epidural
Medication is delivered through the sacral hiatus at the base of the spine and may be appropriate for certain lower lumbar or sacral symptoms.
Selective Nerve Root Block
A more targeted injection near a specific nerve root, which may also serve a diagnostic purpose to help confirm the symptomatic nerve level.
Candidacy
When May Epidural Steroid Injections Be Considered?
Epidural steroid injections may be considered for selected patients with:
- Radicular pain related to a herniated disc or spinal stenosis
- Cervical or lumbar nerve root irritation with radiating symptoms
- Symptoms that have not improved adequately with conservative treatment
- Symptoms significant enough to warrant procedural evaluation
Epidural steroid injections are not appropriate for every patient with back, neck, or leg pain. A clinical evaluation is required to determine appropriateness.
Limitations
Important Limitations.
Response to epidural steroid injections varies among patients. The procedure may provide temporary relief, partial relief, or no relief. Multiple injections may be considered in appropriate clinical circumstances, and the number of injections appropriate for a given patient depends on the clinical response and overall context.
As with any medical procedure, epidural steroid injections carry potential risks. Risks and benefits should be discussed in detail with the treating physician before any procedure is performed.
