When Is a Caudal Epidural Injection Recommended? A Consultant Orthopaedic Spine Surgeon's Guide
A caudal epidural may help when conditions like sciatica or spinal stenosis cause persistent pain. It is especially beneficial if physiotherapy and medication have not resolved the issue. This procedure can both relieve pain and confirm a diagnosis. A positive response indicates which spinal structures are involved. Dr. Purnajyoti Banerjee, a consultant orthopaedic spine surgeon, performs these injections under image guidance at his Harley Street Hospital in London.
Conditions Treated with Caudal Epidural Injection
- Sciatica
- Spinal stenosis

- Post-surgical nerve pain
What Happens During the Procedure?
BEFORE
You can eat and drink normally unless sedation is planned. Arrive 30 minutes early for consent confirmation and questions.
DURING
Lying face-down, sedation is administered and skin is numbed. Under X-ray guidance, a needle is placed through the sacral hiatus, administering medication around the affected nerves.
AFTER
You rest for 30 to 60 minutes before going home the same day with a companion. Mild soreness is normal, and relief typically builds over 2 to 10 days.

- Diagnostic value for planning future treatment
- Can be repeated if clinically appropriate
Considerations
- Relief varies between patients and is not guaranteed
