When Is Surgery Necessary for a Disc Herniation?

By Dr. Gerry Nastasia, DC, DABCO, DIANM | Primary Spine Practitioner | Dubai

You’ve been told you have a herniated disc. Maybe your MRI confirmed it. Maybe you’ve been living with pain, numbness, or weakness for weeks or even months. And now someone has mentioned the word surgery.

It’s a word that stops most people cold.

In over 36 years of treating spine conditions across multiple countries, I’ve seen this moment play out hundreds of times. A patient sits across from me, scared, confused, and wondering: “Do I actually need surgery? Or is there another way?”

The honest answer the one I give every single patient  is this: most herniated discs do not require surgery. But some do. And knowing the difference could save you months of unnecessary suffering, or protect you from delaying a procedure you genuinely need.

What Is a Disc Herniation? (A Quick Recap)

Your spine is made up of bones called vertebrae, and between each one sits a spinal disc  a tough outer ring (the annulus fibrosus) surrounding a soft, gel-like center (the nucleus pulposus). When that outer ring tears or weakens, the inner gel can push through. That’s a herniation.

Depending on where it presses, you can experience:

• Back pain or neck pain at the level of the disc
• Radiating pain (sciatica in the legs, or radiculopathy in the arms)
• Numbness or tingling along a nerve pathway
• Muscle weakness in the arms, hands, legs, or feet

The most common levels are L4-L5 and L5-S1 in the lower back, and C5-C6 and C6-C7 in the neck.

Here’s what most people don’t realize: a herniated disc on an MRI doesn’t automatically mean surgery. The scan shows the disc. It doesn’t tell you how the disc is responding to treatment or whether your body is already beginning to heal itself.

The Good News: Your Body Can Heal a Herniated Disc

A process called resorption occurs in many herniated discs. Over time  typically weeks to months the herniated disc material can shrink, be absorbed by the body’s immune cells, and reduce pressure on the nerve. Studies consistently show that larger herniations actually resorb more than smaller ones, which is counterintuitive but true.

This is why the standard first approach for most disc herniations is conservative care non-surgical treatment that gives the body the best chance to heal on its own.

Conservative Treatment: What Should Come First

Before surgery is ever considered, the following approaches should be tried and given adequate time to work:

1. Chiropractic Care (Including Flexion-Distraction Decompression)

As the only certified Cox Flexion-Distraction Decompression Manipulation provider in the Middle East, this is an approach I use extensively for disc herniation patients. Cox Technique involves gentle, controlled movement that decompresses the disc, reduces intradiscal pressure, and restores normal spinal mechanics without any twisting or high-force manipulation. Many patients experience meaningful improvement within 4-6 weeks of consistent treatment.

2. Physical Therapy and Rehabilitation

Targeted exercises that strengthen the muscles supporting the spine can take load off the disc and reduce nerve irritation. McKenzie Method exercises, core stabilization, and posture correction all play important roles.

3. Pain Management (Short-Term)

Anti-inflammatory medications, muscle relaxants, and in some cases epidural steroid injections can manage pain well enough to allow participation in rehabilitation. These aren’t long-term fixes but they can be an important bridge.

4. Activity Modification

This doesn’t mean bed rest. Bed rest is actually counterproductive for most disc herniations. It means learning which movements aggravate the disc, temporarily modifying those activities, and gradually returning to full function.

The general guideline: conservative care should be given a genuine trial typically 6 to 12 weeks before surgery is considered, unless there are urgent symptoms present.

So When Does Surgery Become Necessary?

The answer falls into two categories: urgent situations and elective situations.

Category 1: Urgent Surgery May Be Needed Quickly

There are specific warning signs with disc herniations that indicate a genuine neurological emergency.

Cauda Equina Syndrome

This is the most serious complication of a lumbar disc herniation and represents a true surgical emergency. The cauda equina is a bundle of nerve roots at the bottom of the spinal cord. If a herniated disc compresses these nerves severely, it can cause:

• Loss of bladder or bowel control (or sudden retention)
• Saddle anesthesia numbness in the groin, inner thighs, and buttocks
• Progressive weakness in both legs
• Sexual dysfunction

If you or someone you know develops these symptoms alongside back pain, do not wait. Go to an emergency room immediately. Surgery must typically occur within 24-48 hours to prevent permanent loss of bladder and bowel function.

Rapidly Progressive Neurological Deficit

If you’re losing strength in a limb and losing it quickly over days that’s a red flag. Foot drop developing rapidly, sudden worsening hand weakness with a cervical herniation, or progressive leg weakness making it difficult to walk all warrant urgent evaluation. When neurological function is declining fast, waiting too long risks permanent nerve damage.

Category 2: Elective When Conservative Care Has Failed

The more common scenario: a patient has received appropriate conservative treatment for 6-12 weeks, and the improvement simply isn’t enough. They’re still unable to work, sleep, or participate in normal daily life. Situations that commonly reach this point include:

• Persistent severe sciatica that remains disabling despite months of chiropractic care, physiotherapy, and pain management
• Persistent arm radiculopathy from a cervical herniation that hasn’t responded to conservative care and is significantly affecting function
• Intractable pain so severe it cannot be managed enough to allow normal rehabilitation

What Type of Surgery Is Usually Done?

Modern disc surgery is far less invasive than it was even 20 years ago.

Microdiscectomy (lumbar herniations) The most common procedure. A small incision is made and the portion of the disc pressing on the nerve is removed. Minimally invasive, with typical recovery of 2-6 weeks and success rates for leg pain relief around 85-90%.

Anterior Cervical Discectomy and Fusion (ACDF) (cervical herniations) The disc is removed from the front of the neck and the vertebrae above and below are fused. Most patients return to normal activity within 4-6 weeks.

Cervical Disc Replacement A newer alternative to fusion for appropriate candidates, preserving more natural movement in the neck.

Questions to Ask Before Agreeing to Surgery

If surgery has been recommended, bring these questions to your consultation:

• Is this urgent, or do I have time to try conservative care?
• What specific benefit is surgery expected to provide?
• What does the research say about outcomes for my specific situation?
• What happens if I don’t have surgery? What is the realistic trajectory with conservative care?
• Have I actually had an adequate trial of conservative care  6 to 12 weeks of structured treatment?
• What are the risks of this specific procedure? (infection, nerve injury, failed back surgery syndrome)

A Word From Clinical Experience

In over three decades at the clinical front line, the patients I worry about most are not those who ask hard questions before agreeing to surgery. They are the ones who either rush into surgery before trying anything else, or who wait so long with true emergency symptoms that nerve damage becomes irreversible.

Your spine is not a problem to be solved with a single intervention. It is a structure designed for movement, load, and recovery. Given the right conditions and the right care, it heals more often than people think.

Key Takeaways

• Most herniated discs do not require surgery. The body can and does resorb disc material over time.
• Conservative care should come first chiropractic care (including Cox Flexion-Distraction), physiotherapy, activity modification, and pain management.
• Urgent surgery is needed for cauda equina syndrome and rapidly progressive neurological deficits. Do not delay.
• Elective surgery becomes appropriate when conservative care has genuinely failed after 6-12 weeks and symptoms remain disabling.
• Ask hard questions before agreeing to any surgical procedure.
