Caudal Epidural
What is a Caudal Epidural?
A Caudal Epidural is a minimally invasive spinal injection used to relieve lower back and leg pain caused by inflammation or nerve compression. This procedure involves delivering a combination of local anaesthetic and steroid into the caudal epidural space, located at the base of the spine.
Performed under live X-ray guidance (fluoroscopy), the injection targets the inflamed nerves and spinal structures, helping to reduce pain and improve mobility.
Who Can Benefit from a Caudal Epidural?
A caudal epidural may be recommended for patients experiencing:
-
Chronic lower back pain due to degenerative changes or inflammation.
-
Sciatica – Pain radiating down the leg due to nerve compression.
-
Spinal Stenosis – Narrowing of the spinal canal causing nerve irritation.
-
Herniated (slipped) discs – Bulging discs pressing on spinal nerves.
-
Post-surgical pain – Discomfort following spinal surgery.
What to Expect During the Procedure
Before the Injection:
-
You will be given sedation and local anaesthetic to ensure comfort during the procedure.
-
You will be asked to avoid eating and drinking 6 hours before the procedure.
-
The procedure usually takes around 15 minutes
-
A doctor will explain the procedure and answer any questions you may have.
During the Injection:
-
You will lie on your front on an X-ray table.
-
The skin over the lower back will be cleaned and numbed with a local anaesthetic.
-
Using live X-ray guidance (fluoroscopy), a fine needle is inserted into the caudal epidural space.
-
A contrast dye may be used to confirm accurate placement before the local anaesthetic and steroid are injected.
-
The procedure typically takes 20–30 minutes.
After the Injection:
-
You will be monitored briefly in a recovery area before going home.
-
It is recommended that you arrange for someone to drive you home due to the sedation.
Recovery & Aftercare
- Pain Relief: Some patients experience immediate relief, while others notice gradual improvement over several days as the steroid takes effect.
- Activity Restrictions: Avoid strenuous activities for 24–48 hours but return to light daily activities as tolerated.
- Side Effects: Mild soreness at the injection site is common. Temporary leg numbness or weakness may occur but usually resolves within a few hours.
- Follow-Up: If successful, repeat injections may be considered in the future if pain recurs.
How Long Do the Effects Last?
Relief from a caudal epidural can last several weeks to months, depending on the individual and the underlying condition being treated. Some patients may require additional treatments or alternative therapies for long-term pain management.
