Caudal Epidural Injection
What is a Caudal Epidural Injection?
A Caudal Epidural Injection is a minimally invasive pain management procedure in which anti-inflammatory medication is delivered into the epidural space through the sacral hiatus, located at the base of the spine.
This technique allows medication to reach multiple lower spinal nerve roots and is commonly used to treat chronic lower back pain, sciatica, spinal stenosis, and post-surgical spinal pain.
Caudal epidural injections are often recommended when conservative treatments such as medication and physical therapy have not provided sufficient relief.

Conditions Treated
Caudal Epidural Injections may be recommended for:
- Lumbar disc herniation
- Sciatica
- Lumbar spinal stenosis
- Degenerative disc disease
- Chronic lower back pain
- Post-laminectomy syndrome (Failed Back Surgery Syndrome)
- Nerve root irritation and inflammation
Symptoms That May Benefit from Treatment
- Chronic lower back pain
- Pain radiating into the buttocks or legs
- Numbness and tingling in the legs
- Burning or electric shock-like sensations
- Weakness related to nerve irritation
- Difficulty standing or walking for extended periods
Goals of Treatment
The primary goals of treatment include:
- Reducing pain and inflammation
- Relieving pressure and irritation around spinal nerves
- Improving mobility and walking capacity
- Supporting rehabilitation and exercise participation
- Reducing dependence on pain medications
- Improving overall function and quality of life
Treatment Process
Caudal Epidural Injection is typically performed as an outpatient procedure.
The procedure generally includes:
- Clinical evaluation and imaging review
- Local anesthesia of the treatment area
- Image-guided needle placement through the sacral hiatus
- Injection of medication into the epidural space
- Short observation period following treatment
The procedure usually takes between 15 and 30 minutes.
Who Can Benefit?
Caudal Epidural Injection may be suitable for:
- Patients with chronic lower back pain
- Individuals with sciatica
- Patients with lumbar spinal stenosis
- Individuals with persistent symptoms after spinal surgery
- Patients seeking minimally invasive pain management options
Recovery and Rehabilitation
Most patients can return to light daily activities within 24 hours.
For optimal long-term results, the procedure is often combined with:
- Spine rehabilitation programs
- Exercise therapy
- Core strengthening exercises
- Postural training
- Functional rehabilitation
Combining interventional pain management with rehabilitation helps address both symptoms and their underlying causes.
Frequently Asked Questions (FAQ)
A Caudal Epidural Injection is administered through the sacral opening at the base of the spine, allowing medication to spread across multiple lower spinal nerve roots. It is particularly useful for lower back and leg pain.
Most patients experience minimal discomfort because local anesthesia is used during the procedure.
Relief varies between individuals and may last from several weeks to several months.
Some patients experience relief within a few days, while others notice gradual improvement over one to two weeks.
Yes. Caudal Epidural Injection is commonly used for persistent pain following spinal surgery.
Yes. Depending on the patient's response and clinical condition, repeat injections may be considered.
