Diagnostic and therapeutic spinal interventions: Epidural injections

Area of Science:

• Pain Medicine
• Neurology
• Interventional Radiology

Background:

• Epidural injections are common for diagnosing and treating radicular pain.
• Transforaminal approach in the lumbar spine has strong evidence.
• Selective nerve blocks can identify specific pain-causing nerves.

Purpose of the Study:

• To review the diagnostic and therapeutic applications of epidural injections for radicular pain.
• To highlight the evidence supporting the transforaminal approach.
• To discuss patient selection and potential risks.

Main Methods:

• Review of existing evidence on epidural injections.
• Analysis of diagnostic utility of selective nerve blocks.
• Assessment of risks associated with epidural steroid injections.

Main Results:

• Many patients experience significant benefit from a single therapeutic epidural injection.
• Transforaminal lumbar epidural injections show the best evidence.
• Short-term serious risks are rare; long-term risks are infrequent.

Conclusions:

• Epidural injections are a valuable tool for managing radicular pain.
• Patient selection is key, particularly for those failing conservative therapy.
• Careful consideration of risks versus benefits is necessary for optimal patient outcomes.
